:alarm_clock: :fire: A TCP proxy to simulate network and system conditions for chaos and resiliency testing

Toxiproxy

Toxiproxy is a framework for simulating network conditions. It's made specifically to work in testing, CI and development environments, supporting deterministic tampering with connections, but with support for randomized chaos and customization. Toxiproxy is the tool you need to prove with tests that your application doesn't have single points of failure. We've been successfully using it in all development and test environments at Shopify since October, 2014. See our blog post on resiliency for more information.

Toxiproxy usage consists of two parts. A TCP proxy written in Go (what this repository contains) and a client communicating with the proxy over HTTP. You configure your application to make all test connections go through Toxiproxy and can then manipulate their health via HTTP. See Usage below on how to set up your project.

For example, to add 1000ms of latency to the response of MySQL from the Ruby client:

Toxiproxy[:mysql_master].downstream(:latency, latency: 1000).apply do
  Shop.first # this takes at least 1s
end

To take down all Redis instances:

Toxiproxy[/redis/].down do
  Shop.first # this will throw an exception
end

While the examples in this README are currently in Ruby, there's nothing stopping you from creating a client in any other language (see Clients).

Why yet another chaotic TCP proxy?

The existing ones we found didn't provide the kind of dynamic API we needed for integration and unit testing. Linux tools like nc and so on are not cross-platform and require root, which makes them problematic in test, development and CI environments.

Clients

• toxiproxy-ruby
• toxiproxy-go
• toxiproxy-python
• toxiproxy.net
• toxiproxy-php-client
• toxiproxy-node-client
• toxiproxy-java
• toxiproxy-haskell

Example

Let's walk through an example with a Rails application. Note that Toxiproxy is in no way tied to Ruby, it's just been our first use case. You can see the full example at sirupsen/toxiproxy-rails-example. To get started right away, jump down to Usage.

For our popular blog, for some reason we're storing the tags for our posts in Redis and the posts themselves in MySQL. We might have a Post class that includes some methods to manipulate tags in a Redis set:

class Post < ActiveRecord::Base
  # Return an Array of all the tags.
  def tags
    TagRedis.smembers(tag_key)
  end

  # Add a tag to the post.
  def add_tag(tag)
    TagRedis.sadd(tag_key, tag)
  end

  # Remove a tag from the post.
  def remove_tag(tag)
    TagRedis.srem(tag_key, tag)
  end

  # Return the key in Redis for the set of tags for the post.
  def tag_key
    "post:tags:#{self.id}"
  end
end

We've decided that erroring while writing to the tag data store (adding/removing) is OK. However, if the tag data store is down, we should be able to see the post with no tags. We could simply rescue the Redis::CannotConnectError around the SMEMBERS Redis call in the tags method. Let's use Toxiproxy to test that.

Since we've already installed Toxiproxy and it's running on our machine, we can skip to step 2. This is where we need to make sure Toxiproxy has a mapping for Redis tags. To config/boot.rb (before any connection is made) we add:

require 'toxiproxy'

Toxiproxy.populate([
  {
    name: "toxiproxy_test_redis_tags",
    listen: "127.0.0.1:22222",
    upstream: "127.0.0.1:6379"
  }
])

Then in config/environments/test.rb we set the TagRedis to be a Redis client that connects to Redis through Toxiproxy by adding this line:

TagRedis = Redis.new(port: 22222)

All calls in the test environment now go through Toxiproxy. That means we can add a unit test where we simulate a failure:

test "should return empty array when tag redis is down when listing tags" do
  @post.add_tag "mammals"

  # Take down all Redises in Toxiproxy
  Toxiproxy[/redis/].down do
    assert_equal [], @post.tags
  end
end

The test fails with Redis::CannotConnectError. Perfect! Toxiproxy took down the Redis successfully for the duration of the closure. Let's fix the tags method to be resilient:

def tags
  TagRedis.smembers(tag_key)
rescue Redis::CannotConnectError
  []
end

The tests pass! We now have a unit test that proves fetching the tags when Redis is down returns an empty array, instead of throwing an exception. For full coverage you should also write an integration test that wraps fetching the entire blog post page when Redis is down.

Full example application is at sirupsen/toxiproxy-rails-example.

Usage

Configuring a project to use Toxiproxy consists of three steps:

1. Installing Toxiproxy
2. Populating Toxiproxy
3. Using Toxiproxy

1. Installing Toxiproxy

Linux

See Releases for the latest binaries and system packages for your architecture.

Ubuntu

$ wget -O toxiproxy-2.1.4.deb https://github.com/Shopify/toxiproxy/releases/download/v2.1.4/toxiproxy_2.1.4_amd64.deb
$ sudo dpkg -i toxiproxy-2.1.4.deb
$ sudo service toxiproxy start

OS X

With Homebrew:

$ brew tap shopify/shopify
$ brew install toxiproxy

Or with MacPorts:

$ port install toxiproxy

Windows

Toxiproxy for Windows is available for download at https://github.com/Shopify/toxiproxy/releases/download/v2.1.4/toxiproxy-server-windows-amd64.exe

Docker

Toxiproxy is available on Github container registry. Old versions <= 2.1.4 are available on on Docker Hub.

$ docker pull ghcr.io/shopify/toxiproxy
$ docker run --rm -it ghcr.io/shopify/toxiproxy

If using Toxiproxy from the host rather than other containers, enable host networking with --net=host.

$ docker run --rm --entrypoint="/toxiproxy-cli" -it ghcr.io/shopify/toxiproxy list

Source

If you have Go installed, you can build Toxiproxy from source using the make file:

$ make build
$ ./toxiproxy-server

Upgrading from Toxiproxy 1.x

In Toxiproxy 2.0 several changes were made to the API that make it incompatible with version 1.x. In order to use version 2.x of the Toxiproxy server, you will need to make sure your client library supports the same version. You can check which version of Toxiproxy you are running by looking at the /version endpoint.

See the documentation for your client library for specific library changes. Detailed changes for the Toxiproxy server can been found in CHANGELOG.md.

2. Populating Toxiproxy

When your application boots, it needs to make sure that Toxiproxy knows which endpoints to proxy where. The main parameters are: name, address for Toxiproxy to listen on and the address of the upstream.

Some client libraries have helpers for this task, which is essentially just making sure each proxy in a list is created. Example from the Ruby client:

# Make sure `shopify_test_redis_master` and `shopify_test_mysql_master` are
# present in Toxiproxy
Toxiproxy.populate([
  {
    name: "shopify_test_redis_master",
    listen: "127.0.0.1:22220",
    upstream: "127.0.0.1:6379"
  },
  {
    name: "shopify_test_mysql_master",
    listen: "127.0.0.1:24220",
    upstream: "127.0.0.1:3306"
  }
])

This code needs to run as early in boot as possible, before any code establishes a connection through Toxiproxy. Please check your client library for documentation on the population helpers.

Alternatively use the CLI to create proxies, e.g.:

toxiproxy-cli create -l localhost:26379 -u localhost:6379 shopify_test_redis_master

We recommend a naming such as the above: <app>_<env>_<data store>_<shard>. This makes sure there are no clashes between applications using the same Toxiproxy.

For large application we recommend storing the Toxiproxy configurations in a separate configuration file. We use config/toxiproxy.json. This file can be passed to the server using the -config option, or loaded by the application to use with the populate function.

An example config/toxiproxy.json:

[
  {
    "name": "web_dev_frontend_1",
    "listen": "[::]:18080",
    "upstream": "webapp.domain:8080",
    "enabled": true
  },
  {
    "name": "web_dev_mysql_1",
    "listen": "[::]:13306",
    "upstream": "database.domain:3306",
    "enabled": true
  }
]

Use ports outside the ephemeral port range to avoid random port conflicts. It's 32,768 to 61,000 on Linux by default, see /proc/sys/net/ipv4/ip_local_port_range.

3. Using Toxiproxy

To use Toxiproxy, you now need to configure your application to connect through Toxiproxy. Continuing with our example from step two, we can configure our Redis client to connect through Toxiproxy:

# old straight to redis
redis = Redis.new(port: 6380)

# new through toxiproxy
redis = Redis.new(port: 22220)

Now you can tamper with it through the Toxiproxy API. In Ruby:

redis = Redis.new(port: 22220)

Toxiproxy[:shopify_test_redis_master].downstream(:latency, latency: 1000).apply do
  redis.get("test") # will take 1s
end

Or via the CLI:

toxiproxy-cli toxic add -t latency -a latency=1000 shopify_test_redis_master

Please consult your respective client library on usage.

4. Logging

There are the following log levels: panic, fatal, error, warn or warning, info, debug and trace. The level could be updated via environment variable LOG_LEVEL.

Toxics

Toxics manipulate the pipe between the client and upstream. They can be added and removed from proxies using the HTTP api. Each toxic has its own parameters to change how it affects the proxy links.

For documentation on implementing custom toxics, see CREATING_TOXICS.md

latency

Add a delay to all data going through the proxy. The delay is equal to latency +/- jitter.

Attributes:

• latency: time in milliseconds
• jitter: time in milliseconds

down

Bringing a service down is not technically a toxic in the implementation of Toxiproxy. This is done by POSTing to /proxies/{proxy} and setting the enabled field to false.

bandwidth

Limit a connection to a maximum number of kilobytes per second.

Attributes:

• rate: rate in KB/s

slow_close

Delay the TCP socket from closing until delay has elapsed.

Attributes:

• delay: time in milliseconds

timeout

Stops all data from getting through, and closes the connection after timeout. If timeout is 0, the connection won't close, and data will be delayed until the toxic is removed.

Attributes:

• timeout: time in milliseconds

reset_peer

Simulate TCP RESET (Connection reset by peer) on the connections by closing the stub Input immediately or after a timeout.

Attributes:

• timeout: time in milliseconds

slicer

Slices TCP data up into small bits, optionally adding a delay between each sliced "packet".

Attributes:

• average_size: size in bytes of an average packet
• size_variation: variation in bytes of an average packet (should be smaller than average_size)
• delay: time in microseconds to delay each packet by

limit_data

Closes connection when transmitted data exceeded limit.

• bytes: number of bytes it should transmit before connection is closed

HTTP API

All communication with the Toxiproxy daemon from the client happens through the HTTP interface, which is described here.

Toxiproxy listens for HTTP on port 8474.

Proxy fields:

• name: proxy name (string)
• listen: listen address (string)
• upstream: proxy upstream address (string)
• enabled: true/false (defaults to true on creation)

To change a proxy's name, it must be deleted and recreated.

Changing the listen or upstream fields will restart the proxy and drop any active connections.

If listen is specified with a port of 0, toxiproxy will pick an ephemeral port. The listen field in the response will be updated with the actual port.

If you change enabled to false, it will take down the proxy. You can switch it back to true to reenable it.

Toxic fields:

• name: toxic name (string, defaults to <type>_<stream>)
• type: toxic type (string)
• stream: link direction to affect (defaults to downstream)
• toxicity: probability of the toxic being applied to a link (defaults to 1.0, 100%)
• attributes: a map of toxic-specific attributes

See Toxics for toxic-specific attributes.

The stream direction must be either upstream or downstream. upstream applies the toxic on the client -> server connection, while downstream applies the toxic on the server -> client connection. This can be used to modify requests and responses separately.

Endpoints

All endpoints are JSON.

• GET /proxies - List existing proxies and their toxics
• POST /proxies - Create a new proxy
• POST /populate - Create or replace a list of proxies
• GET /proxies/{proxy} - Show the proxy with all its active toxics
• POST /proxies/{proxy} - Update a proxy's fields
• DELETE /proxies/{proxy} - Delete an existing proxy
• GET /proxies/{proxy}/toxics - List active toxics
• POST /proxies/{proxy}/toxics - Create a new toxic
• GET /proxies/{proxy}/toxics/{toxic} - Get an active toxic's fields
• POST /proxies/{proxy}/toxics/{toxic} - Update an active toxic
• DELETE /proxies/{proxy}/toxics/{toxic} - Remove an active toxic
• POST /reset - Enable all proxies and remove all active toxics
• GET /version - Returns the server version number
• GET /metrics - Returns Prometheus-compatible metrics

Populating Proxies

Proxies can be added and configured in bulk using the /populate endpoint. This is done by passing a json array of proxies to toxiproxy. If a proxy with the same name already exists, it will be compared to the new proxy and replaced if the upstream and listen address don't match.

A /populate call can be included for example at application start to ensure all required proxies exist. It is safe to make this call several times, since proxies will be untouched as long as their fields are consistent with the new data.

CLI Example

$ toxiproxy-cli create -l localhost:26379 -u localhost:6379 redis
Created new proxy redis
$ toxiproxy-cli list
Listen          Upstream        Name  Enabled Toxics
======================================================================
127.0.0.1:26379 localhost:6379  redis true    None

Hint: inspect toxics with `toxiproxy-client inspect <proxyName>`

$ redis-cli -p 26379
127.0.0.1:26379> SET omg pandas
OK
127.0.0.1:26379> GET omg
"pandas"

$ toxiproxy-cli toxic add -t latency -a latency=1000 redis
Added downstream latency toxic 'latency_downstream' on proxy 'redis'

$ redis-cli -p 26379

127.0.0.1:26379> DEL omg
(integer) 1
(1.00s)

$ toxiproxy-cli toxic remove -n latency_downstream redis
Removed toxic 'latency_downstream' on proxy 'redis'

$ redis-cli -p 26379
127.0.0.1:26379> GET omg
(nil)

$ toxiproxy-cli delete redis
Deleted proxy redis

$ redis-cli -p 26379
Could not connect to Redis at 127.0.0.1:26379: Connection refused

Metrics

Toxiproxy exposes Prometheus-compatible metrics via its HTTP API at /metrics. See METRICS.md for full descriptions

Frequently Asked Questions

How fast is Toxiproxy? The speed of Toxiproxy depends largely on your hardware, but you can expect a latency of < 100µs when no toxics are enabled. When running with GOMAXPROCS=4 on a Macbook Pro we achieved ~1000MB/s throughput, and as high as 2400MB/s on a higher end desktop. Basically, you can expect Toxiproxy to move data around at least as fast the app you're testing.

Can Toxiproxy do randomized testing? Many of the available toxics can be configured to have randomness, such as jitter in the latency toxic. There is also a global toxicity parameter that specifies the percentage of connections a toxic will affect. This is most useful for things like the timeout toxic, which would allow X% of connections to timeout.

I am not seeing my Toxiproxy actions reflected for MySQL. MySQL will prefer the local Unix domain socket for some clients, no matter which port you pass it if the host is set to localhost. Configure your MySQL server to not create a socket, and use 127.0.0.1 as the host. Remember to remove the old socket after you restart the server.

Toxiproxy causes intermittent connection failures. Use ports outside the ephemeral port range to avoid random port conflicts. It's 32,768 to 61,000 on Linux by default, see /proc/sys/net/ipv4/ip_local_port_range.

Should I run a Toxiproxy for each application? No, we recommend using the same Toxiproxy for all applications. To distinguish between services we recommend naming your proxies with the scheme: <app>_<env>_<data store>_<shard>. For example, shopify_test_redis_master or shopify_development_mysql_1.

Development

• make. Build a toxiproxy development binary for the current platform.
• make all. Build Toxiproxy binaries and packages for all platforms. Requires to have Go compiled with cross compilation enabled on Linux and Darwin (amd64) as well as goreleaser in your $PATH to build binaries the Linux package.
• make test. Run the Toxiproxy tests.

Release

See RELEASE.md

toxiproxy's Issues

Go API

We should have a Go API for toxiproxy. It wouldn't be hard to test, as it's essentially what's already in api_test.go, it just needs to be in a sub package that can be imported independently of the Toxiproxy daeamon.

how to access request and response data from the proxy server

Hi,
I want to manipulate and recognize errors from the requests and response data which are passing through the proxy server.
What are is the proper way of doing that?
It would be nice to if someone explains it step by step.

Proxy name conflicts leak ports

If a proxy is added with a conflicting name, but not a conflicting port, the port will be opened before an error is returned, leaving the port open.
There's currently no way to close the port other than restarting toxiproxy.

See tests added in the toxiproxy2 branch: 53773f6#diff-095e965c1e92c9277036371d89bd083cR262
and the tests failing here: https://circleci.com/gh/Shopify/toxiproxy/295

Unable to update toxic name and stream property

Hi,

I noticed that creating a proxy with a toxic and sending POST request to the URL http://localhost:8474/proxies/{proxyname}/toxics/{toxicname}, I cannot update the toxic name and the stream attribute.
Is this by design?

Better Go api

The current Go API is pretty low-level, something with closures or a context object would be great.

Package loss toxic

Would it be possible to add a toxic that simulates package loss?

DNS

A lot of software assumes fast DNS lookups. Let's challenge assumptions!

toxiproxy-cli hangs in docker connecting to local toxproxy (related to internet?)

hello!
new toxiproxy user here, trying out my first toxic steps.
I run it in docker, using the latest image that was just pushed today.
just 1 proxy and 1 backend, very light load.

i noticed that toxiproxy-cli, which worked fine first to add a proxy and a toxic, on subsequest commands started hanging. i ctrl-c'd the commands after they hung for minutes (the last 3 commands).

interesting to mention: around the same time my internet connection also became slow and started timing out. while everything is local in a dockerstack entirely on my laptop, maybe my internet has something to do with it? has anyone experienced something like this before?

Change to IP proxy instead of TCP proxy

It'd make sense for the proxy to be at layer 3, instead of layer 4. Means we can re-order packets, etc., and rely on the TCP implementation to provide the stream. It'd also make us able to support UDP, SCTP, etc.

@xthexder

Protocol aware toxics

We could build protocol aware toxics, e.g.

• HTTP. Send extremely large headers, slow headers, slow body but fast headers, 5xx, infinite redirects..
• Redis. Slow writes and fast reads, out of memory conditions (reads but no writes), ..

404s for toxics and reset

I set up Toxiproxy(1.2.1 from the .deb) with 3 servers. When i go to http://localhost:8474/proxies or do Toxiproxy.all I get results back, but when I try to examine the toxics for any of the servers, it 404s. Same with Toxiproxy.reset. Surely there's something simple I'm missing.

Individual proxies work as well. Toxiproxy[:my_service] works fine. It's Toxiproxy[:my_service].toxics that 404s

docker image no longer updating?

Hello,
toxiproxy looks like a neat project. looking forward to play with it.
on https://hub.docker.com/r/shopify/toxiproxy/tags/ i see that the last image push was 6 months ago, whereas https://github.com/Shopify/toxiproxy/blob/master/Dockerfile was updated less than 2 months ago
also the current latest image has nothing in /go/bin, and no toxiproxy-cli binary anywhere:

looking forward to have new images that have the toxiproxy-cli binary included. thanks

Issues with re-routing https traffic

Hi,

I'm trying to setup a proxy for the https port 443.
I've made the change such that the service in my VM runs on 488, and have used toxy-proxy cli to create a proxy which runs on 443, and forwards it to 488.

./toxiproxy-cli-linux-amd64 create Navaneethan --listen localhost:443 --upstream localhost:488

The problem however is, I see a bunch of "source Terminated" messages on the toxy-proxy-server.
Something like this.

My question is, does toxy proxy support https traffic routing ? What am I missing. Is there any specific configuration change on the apache webserver that lets me route the https traffic ?

Any help is appreciated.

the deb package does not install any init.d file

wget -O toxiproxy-1.2.1.deb https://github.com/Shopify/toxiproxy/releases/download/v1.2.1/toxiproxy_1.2.1_amd64.deb
$ sudo dpkg -i toxiproxy-1.2.1.deb
$ sudo service toxiproxy start

for ubuntu, however when installing it on a ubuntu 14.04 , I can't do the service start

cli: Allow host to be specified

At Shopify we use a VM to run services that a project depends on, including toxiproxy. Unfortunately, toxiprox-cli is hard coded to use localhost. That means that toxiproxy-cli can't be used from outside of the VM

I think there should be a global option to specify the host. E.g. toxiproxy-cli --host=example.com list

better CLI error handling

#112 updates our CLI library to a newer version with better error handling. We should figure out how this error handling works and change toxiAction to support the new error handling if it's a cleaner solution.

toxiAction should be updated to look something like this.

type toxiAction func(*cli.Context, *toxiproxy.Client) error

return func(c *cli.Context) error {
    return f(c, t)
}

And then all the action error handling should be ported to the new API.

No docker image?

It seems so that no docker image is available ❗ ❓

Integrate with `goproxy`

Have you taken a look at https://github.com/abourget/goproxy ? I'd really like to be able to integrate both toxiproxy and goproxy.. to be able to instrument a proxy for multiple purposes, and adding to the mix toxicity..

Do you think it'd be easy ?

Update Brew formula

bin.install "1.0.0-darwin-amd64" => "toxiproxy"
to
bin.install "toxiproxy-darwin-amd64" => "toxiproxy"

Otherwise you get an error:
Error: No such file or directory - 1.0.0-darwin-amd64

Open Source Steps

• Test current master with Shopify
• Create a new Rails app on Ubuntu, go through all the steps, make sure it works
• Use #populate in Shopify from toxiproxy-ruby
• Use new enabled API in toxiproxy-ruby
• Upgrade toxiproxy-ruby in Shopify
• Create a new Rails app on OS X with the current tap, go through all the steps, make sure it works
• When all of the above is done, tag 1.0.0
• Prepare binaries for Linux and Darwin, build .deb package, add all to Github release
• Update Homebrew tap Shopify/homebrew-shopify to point to new binary
• Review README
• Click the Open Source buttons!

@xthexder @camilo , haven't included all the stuff I've already done (readme, how to build packages, etc)

Provide -master docker images

Currently :latest docker image is a build of 2.0.0 without /populate endpoint. It will be handy to have image of current -master.

do flakey latency tests point to a larger problem?

#112 changes the maximum latency allowed in a test from n + 10ms to n + 20ms. Have these tests always been flakey? (I doubt it.)

If not, does this increase in latency affect all toxics or just the latency one. Why? (If it's just the latency toxic, then I think this issue can be closed.)

chat room?

Have you considered creating a chat room for this project or do you think it would be too low traffic to be worthwhile?
I certainly have a few questions that would get ironed out much quicker - and some ideas for the project - if there was a chat where developers and users could unite.

thanks,
Dieter

how to specify multiple attributes? incorrect handling of errors

problem 1) it's unclear how to specify multiple attributes when adding a toxic.
the example in the readme only uses one attribute
(https://github.com/Shopify/toxiproxy#cli-example)
and the cli help docs don't specify how to specify multiple attributes (see help msg below). as a user I'm guessing either specify -a key=val,key2=val2 or -a key=val -a key2=val2

cli toxic add                                                                                                                                                          
NAME:
   toxiproxy-cli toxic add - add a new toxic

USAGE:
   toxiproxy-cli toxic add [command options] <proxyName>

OPTIONS:
   --toxicName value, -n value    name of the toxic
   --type value, -t value         type of toxic
   --toxicity value, --tox value  toxicity of toxic
   --attribute value, -a value    toxic attribute in key=value format
   --upstream, -u                 add toxic to upstream
   --downstream, -d               add toxic to downstream

Proxy name is required as the first argument.

problem 2) either approach i guessed above seems to work sort of, but things aren't exactly working.

approach 1 - comma separated items - seems to be the right way, see this run in the latest docker container...

... so the inspect output looks good. however, I'm having issues getting it to work. it seems to be deplaying requests some of the time but also long periods of undelayed, non-toxic proxying.

so I tried the other way but now latency is set to 0 for some reason, so maybe it's the comma separated approach after all?
edit: in testing the toxic does seem to work effectively

When I try this outside of the docker container, using the latest code in git, the comma separated approach doesn't work at all and I have to switch to multiple -a args

$ ./cli toxic add -t latency -a latency=1000,jitter=500 web
Failed to add toxic: AddToxic: HTTP 400: bad request body: json: cannot unmarshal string into Go value of type int64

$ ./cli toxic add -t latency -a latency=1000 -a jitter=500 web
Added downstream latency toxic 'latency_downstream' on proxy 'web'

the first one submits json like:

{"name":"","type":"latency","stream":"downstream","toxicity":1,"attributes":{"latency":"1000,jitter=500"}}

which looks invalid. the second approach submits:

{"attributes":{"latency":1000,"jitter":500},"name":"latency_downstream","type":"latency","stream":"downstream","toxicity":1}

Alternative to current Node client

The current Node client is out of date and it doesn't have any tests, and I have made a Node client compatible with toxiproxy-2.0 and it has tests.

I have made it out of necessity for my personal use and as an educational task in authoring a Node package written in TypeScript.

https://github.com/ihsw/toxiproxy-node-client

https://www.npmjs.com/package/toxiproxy-node-client

What are your thoughts on switching the docs to mention mine?

Slow TCP Accept and Read cannot be simulated

Currently a proxy will always accept new connections right away, so there is no way to test client connection timeouts (only connection refused when the proxy is disabled).

It is also not possible to test Write failures/timeouts since #67. All incoming data will be read in and buffered by toxiproxy right away, so TCP Writes can't fail on either the server or client.

Expose via DNS

It'd be cool if Toxiproxy could expose its local running services via DNS. Especially because this would make the development environment more like production by using DNS as well.

Return 400 when name is empty

When creating a new Proxy and name is empty it should return 400

Separate development from master branch

Recently it seems there's been some issues and confusion over what versions are released and what documentation matches what.

Currently the master README.md is a bit of a mix between 2.0.0 documentation and upcoming 2.1.0 changes.
I think it may be beneficial to move 2.1.0 development to a dev branch, so that master is always the most recent release, and has the corresponding documentation.
This also makes staging README changes much easier for future releases.

Thoughts?

macOS Sierra issue

After creating a new proxy and adding a latency toxic:

toxiproxy-cli create postgres --listen 127.0.0.1:5434 --upstream 127.0.0.1:5432
toxiproxy add postgres --type latency --toxicName latency --attributes latency=10 --downstream

Trying to establish a connection via PSQL never succeeds:

psql -d postgres://127.0.0.1:5434/postgres?sslmode=disable

However, connecting directly on port 5432 (not via toxiproxy) continues to work fine.

This is affecting a machine running macOS 10.12.1. The setup detailed above with toxiproxy works fine on OSX El Capitan 10.11.6.

Any help debugging this would be most appreciated!

---

Version information:

• toxiproxy-cli version 2.0.0 (installed via Homebrew)
• psql (PostgreSQL) 9.5.5

Dockerfile not port forwarding

Hello there! 👋

I'm currently running this within our CI system and noticed that accessing the HTTP API doesn't work unless I explicitly forward 8474 to 8474 inside the container (usually via -p 8474:8474).

I'm unsure if this is a bug or you handle this differently in your setup? My setup looks like this:

docker pull shopify/toxiproxy
docker run -it -d -p 8474:8474 shopify/toxiproxy

# create HTTP requests for proxies and toxics
# run rspec

Interested to hear your thoughts on this one but if it is a bug I'll gladly open a PR to get it fixed.

Support for cluster of toxiproxy nodes

It would be nice if we can setup a cluster of toxiproxy nodes so that can use a load balancer to balance loads between these nodes. This avoids a single point of failure.

If a toxic is configured in any of the nodes, it should propagate to all nodes in the cluster automatically.

Want to check if this feature looks interesting with everyone.

Wrong response when creating a toxic

Hi,

I'm having a problem when creating a toxic.
If I send ah HTTP POST request to the following URL:

http://localhost:8474/proxies/testingProxy/toxics

where testingProxy is an existing proxy, using the following body:

{
"Name" : "BandwidthToxicTest",
"Stream" : "upstream",
"Enabled" : true,
"Type": "bandwidth",
"Rate" : 100
}

I get the following response:
{
"attributes": {
"rate": 0
},
"name": "BandwidthToxicTest",
"type": "bandwidth",
"stream": "upstream",
"toxicity": 1
}

Why attributes.rate is zero in the response? It should be 100, isn't it?
Thank you.
Regards,
Federico

Data limit toxic suggestion

I need to simulate situation when client sends too much data and server close the connection. Would you accept PR with simple toxic which would do such thing? ... limit how much data can be transferred during single connection but let pass everything before threshold is reached.

Suggestion: Distribute as a Gem

Instead of relying on bootstrap code to update to the latest version, could we add the necessary files to make this a gem and version it using Github's releases?

Batch API / support HTTP pipelines

@BlakeMesdag mentioned that creating proxies at boot of our application actually takes a while, up to 2 seconds. We can make this better. Toxiproxy should not take more than 100ms at boot, and preferably less.

The simplest thing would probably be to support HTTP pipelines / persistent connections, so we can just send a bunch of data. We may also just be doing something stupid in the Rails gem. I'd prefer that to a new API. Another possibility is that the #populate call becomes a native thing in Toxiproxy that just sends it a JSON dictionary of all the proxies it expects (and resets all of them).

@xthexder @jpittis

Populate doesn't compare hostnames properly

When a proxy is created with a hostname such as localhost, toxiproxy will resolve the address and store the ip address 127.0.0.1.
This means that host comparisons such as in /populate will fail unless a static ip is used originally.

The address should be resolved to an IP and then compared after so that comparisons are consistent.

cli's help messages are too abstract, e.g. nothing toxic specific

out of #139 came an interesting point.
per @xthexder:

The cli is designed to be independant of what toxics are defined, so that if a new toxic is added, the cli and api will still work with older versions

interesting choice. this explains another gripe i had as a newcomer to this project: toxiproxy-cli only has help messages for highlevel operations (e.g. create and remove a toxic) but no help messages about which toxics you can add, what their attributes are, etc. It would be nice to be able to have toxiproxy-cli toxic help add list the available toxics and toxiproxy-cli toxic help add latency for example show details about how to add a latency toxic. With the current strategy of keeping the cli generic, this can't be done.
You could technically have the cli query the server for the available toxics, their attributes, which are required vs optional etc and then feed that back to the user, but I would argue that's getting a bit complicated and probably makes it quite hard to dynamically build optimized CLI experiences (see below)

If somebody upgrades their server to support new toxics or new toxic attributes, then it seems very reasonable that they also update the cli as well. given proper packaging / install script /.. this is no extra effort at all.

this way the cli can "truly" support the toxics. and not only could it display more useful help messages, it could also provide a CLI experience that's more optimized. e.g. instead of:
toxiproxy-cli toxic add [command options] <proxyName> with options like --type value, -t value and --attribute value, -a value

you could do:
toxiproxy-cli toxic add [command options] latency <proxyName> with options like --latency and --jitter

this CLI approach seems more user friendly IMHO, I would argue it's a good thing that the cli is optimized for the terminology of the toxics etc instead of trying to be more of a generic json encoder for toxic attributes. If people want that, they can use curl ;)

anyway, please consider this as the way i intend it: constructive feedback.
this project is pretty sweet and I hope to contribute as much as I can (first with some thoughts and ideas, and later hopefully with code as well)

making sure all connections are subject to a toxic / creating proxy-toxic atomically

Hello again Jacob & co,

I'm currently seeing something weird with a proxy that has a latency toxic applied to it with toxicity of 1.0,
for some reason some of the connections that go through it have no latency.

I've tried a few tactics:

1. doing an update on the toxic. because the code looks like it may apply the latency toxic to all active connections going through a proxy, i need to study the code a bit more (pretty intense stuff btw!). this tactic doesn't seem to work: some connections are still undelayed.
2. execute 3 commands (proxy delete, proxy add, and add toxic to proxy) in sequence from a script, trying to minimize the timeframe between them, "hopefully" faster than my application reconnecting. doesn't seem to work: some connections are still undelayed.

Is 1 supposed to work at all? 2 is obviously racey.
Note: I'm using the latest code in git master.
Is there a better way to solve or diagnose this problem? (idea: toxiproxy-cli inspect could do a dump of connections through a proxy and whether they are in noop or toxic mode)

would it make sense to add a mode to toxiproxy-cli to add a proxy and a toxic atomically? So that as soon as the proxy listens, the toxic is ready to be applied for any new incoming connections?
I maybe be able to contribute such a feature, I would just need some direction on how the code should fit together.
Or is there another/better way to enforce a toxic is applied to all connections through a proxy?

Toxiproxy 2.0 RFC

Proposed API Changes

• Remove enabled field from all toxics
• POST /proxies/{proxy}/{up|down}stream/toxics - Create (enable) a new toxic
• POST /proxies/{proxy}/{up|down}stream/toxics/{toxic} - Update an existing toxic
• DELETE /proxies/{proxy}/{up|down}stream/toxics/{toxic} - Destroy (disable) a toxic

This API matches the current proxy creation/deletion api.

Internal Structure Changes

Current 1.x architecture: https://docs.google.com/drawings/d/1pwuRINbpwyaQeYSgGt8VTEKWEUQAwYpNJIMH1owW3Sc/view

Instead of a static number of ToxicStubs (and a static mapping for each toxic), ToxicStubs will be dynamically added / removed as toxics are created/destroyed. A minimum of 1 ToxicStub will always be present, and the first toxic will always be a NoopToxic so that it can be interrupted for inserting / removing toxics.

Steps for adding a new toxic:

1. Interrupt the last toxic in the chain
2. Reconnect the output channels so that the new toxic is between the last toxic and the end ChanReader
3. Resume both ToxicStubs with their toxics

Steps for removing a toxic:

1. Interrupt the toxic before the target in order to ensure the target's input channel is empty
2. Interrupt the target toxic
3. Connect the previous toxic's output to the target toxic's output
4. Resume the previous toxic / ToxicStub pair

This ends up being very similar to a doubly-linked list, except that we need to ensure no data is in-flight between the links (channels) when they're removed.

Toxic Registration

The main() function and server creation will be simplified so that it can be used as a library.
Instead of having all the toxics hard-coded inside toxiproxy, they will be registered in an init() function: toxiproxy.Register(SomeToxic) (this will have to be done with reflection or something...)

This will allow user-created toxics without having to create a full fork of toxiproxy.

Deleting a timeout toxic can lockup proxy http requests

Ran into this issue in some of my tests. Here's the curl commands you can use to recreate this issue.

curl -i -d '{"name": "redis", "upstream": "localhost:6379", "listen": "localhost:26379"}' localhost:8474/proxies
curl -i -d '{"type":"timeout", "timeout":30000, "stream": "upstream"}' localhost:8474/proxies/redis/toxics
curl -m 1 -i 127.0.0.1:26379
curl -m 1 -i -X DELETE localhost:8474/proxies/redis/toxics/timeout

The final delete request seems to lock up (final command must be executed before the 30 second timeout on the toxic), and any future requests like the following no longer returns before timing out

curl -i localhost:8474/proxies

But the version request works fine still curl -i localhost:8474/version returns 2.0.0rc1

@sirupsen @xthexder

Cant access toxiproxy server from outside host

I am not able to hit the toxiproxy server using the REST API for configuring proxies from outside of the host where it is running.

netstat -tulpn shows that it is listening to the loopback address 127.0.0.1:8474

For now as a workaround what I did was to create another proxy which listens on public ip and port 80 and forwards to localhost:8474

PUBLIC_IP:80 --> localhost:8474

Wondering if anyone else faced this issue?

Simplify by always using ProxyWithToxics

Is there any reason why the Proxy type doesn't just have Toxics always? It's perfectly fine for them to be nil. I also think proxies should be returned with toxics in all cases in the API. This simplifies things a great deal.

@xthexder thoughts?

simulate package losses

Is there a feature which can config the percentage of the package losses?

Clarification of timeout toxic behavior

Hey, according to the description of timeout toxic it should stop all data after some specific timeout.

Let's say I have proxy myproxy created

./toxiproxy-cli create myproxy --listen localhost:42666 --upstream google.com:80

And I create new toxic of timeout type with 10s timeout

./toxiproxy-cli toxic add myproxy -n mytoxic --upstream --type timeout --attributes timeout=10000

Processing of simple http get request should take less then 10s so I assume toxiproxy shouldn't interfere in communication. But when I try it I get empty response after 10s. It works well without any toxic enabled.

date -R ; curl -vv localhost:42666 ; date -R

Tue, 16 Aug 2016 15:58:42 +0200

Am I doing something wrong or just don't understand well how it's supposed to work?

Toxics are not set when creating a proxy for the first time.

When using the Go client as follows, toxics are not added to a proxy.
Given var p []toxiproxy.Proxy with toxics.

proxy := client.NewProxy(&p)
proxy.Create()

This does not properly add the configured toxics from p onto the proxy.

They must be added after the fact using Proxy.SetToxic.

simulate cable unplug

Is it possible to simulate a cable being unplugged? It seems timeout stops the data immediately.

I would prefer something like, stop all data (and hang for ever) after x time so I can use it with the toxicity option and have random hangs in the middle of some connections.

Simulate slow connection open

I'm trying to use Toxiproxy to test a connection that is slow to open (I am specifically trying to test our Elastic Search configuration which has both a request_timeout and a request open_timeout which is shorter https://github.com/Shopify/shopify-app-store/pull/1297).

My test fails after the full timeout, not the open timeout (4 vs 2 seconds). From a discussion with @sirupsen he pointed out that this is probably because when the Elastic Search client is routed through Toxiproxy the Toxiproxy server accepts the connection immediately and then applies the toxic. From the Elastic Search client's perspective, it passed the request open_timeout for this reason.

For discussion
@sirupsen @xthexder @jpittis

Race condition in removing a proxy causes panic.

See this CI run of toxiproxy-ruby for an example: https://circleci.com/gh/Shopify/toxiproxy-ruby/18
The build artifact toxiproxy.log contains the stack trace.

What I see happening is the proxy is being closed, and the toxic is being changed at the same time. The packet channel is being closed, but then a new toxic is being started, which will then try to close the channel again.
