codeabovelab / haven-platform

Haven is an open source Docker container management system. It integrates container, application, cluster, image, and registry management in one single place.

Haven: Container Management Simplified

Introduction

Haven is a Docker cluster management system. The user controls the entire platform via user-friendly yet powerful UI and commandline tools. Built on top of Docker, Swarm, and Compose, it offers multiple clusters and image registries management.

• Common Application Properties

Feature Overview

Haven features the following capabilities:

• Dashboard
• Cluster Management
• Container Management
• Node Status
• Image Management
• Registry Management
• Jobs
• Delegated Admin
• Subset of additional features

Dashboard

The dashboard gives an overview of the status of the cluster and any containers or nodes that are using excessive resources.

Cluster Management

In the Cluster module, the user can manage the nodes and the containers, and view any errors the in the cluster event log.

Container Management

In the Containers module, the user can manage all of the active containers and their status. The user can also view logs, moreover, configurations of each container.

Node Status

In the Node module, the user can see all nodes in the system and their detailed info.

Image Management

In the Image Management module, the user can see all of the images downloaded onto each cluster and which nodes the image resides on. Users can remove old images to save disk space.

Registry Management

Private and public Registries can be configured on the system to let the user easily select the desired image for downloading without having to remember which registry it is on.

Jobs

Unattended jobs can be scheduled and results are available for auditing purposes. Each cluster can have its set of jobs to update specific images.

Delegated Admin

Users can be assigned administrative rights to specific clusters to avoid admin bottleneck.

Additional Features

1. Creating/deleting tags and ability to set filters for clusters based on the tags. Use case would be creating workflow: only images which were tested at QA should be visible on the prod cluster.

2. Storing containers configuration in VCS per cluster, see https://github.com/codeabovelab/haven-example-container-configuration

3. Additional policies/constraints for Swarm.

4. Group operations such as cleaning space, upgrade/rollback containers. For example, use cases are:

   a. checking/updating all containers from specified repository every five minutes for test cluster
   
   b. one-time update specified list of containers (which use common API, etc).
   
   c. or just click update all in this cluster
   

5. Backups of system configuration

6. Network management:

7. Events:

8. API

haven-platform's Issues

Add 'unless-stopped' policy support

see com.codeabovelab.dm.cluman.cluster.docker.model.RestartPolicy#parse

Pass timestamp param during creating new job

Currently impossible to create 2 jobs with same parameters (second job will be returned from cache), for avoiding this we need to pass timestamp

Containers 'leak' in etcd

etcdctl ls /cluman/containers|wc -l is 23, but system has only 2 containers

Add support of docker "swarm mode"

Provide support of the new "Swarm mode" available in Docker 1.13 and above.

error while creating container

Create container: nginx of nginx:1.13.1 in cluster1
Creating container with params: ContainerSource(super=EditableContainerSource(cpuShares=null, cpuQuota=null, blkioWeight=null, cpuPeriod=null, cpusetCpus=null, cpusetMems=null, restart=null, memoryLimit=null, memorySwap=null, memoryReservation=null, kernelMemory=null), id=null, image=nginx:1.13.1, imageId=null, cluster=cluster1, node=slave1, application=null, environment=[], include=[], volumes=[], volumeBinds=[], volumeDriver=null, volumesFrom=[], mounts=[], name=nginx, hostname=null, domainname=null, ports={}, labels={}, reschedule=null, publishAllPorts=false, links={}, command=[], entrypoint=[], dns=[], dnsSearch=[], network=null, networks=[], extraHosts=[], securityOpt=[])
{"message":null,"code":"ERROR"}

Improve Install.md

Installation was simplified, doc should be updated

nodes is holded after delete its cluster

Steps to reproduce:

• delete cluster with nodes
• try to create new cluster (important do not reload page) with nodes of deleted cluster

workaround: reload page after cluster deleting

Add "services" tab @ cluster UI

see /swagger-ui.html#/service-api
and /swagger-ui.html#!/cluster-api/listServicesUsingGET

Do not store additional labels in kw

It allows do not keep container information

Simplify updating configuration

Currently updating configuration in git (external configurations) requires deleting/creating container manually. Add button "Recreate" to the UI for simplifying this common operation.
see:
post /ui/api/containers/recreate

Docker stack support

In Docker 1.13, there is a new command 'stack'. It replaces 'compose' that is currently being used. We need to implement the support by:

1. Emulate from https://github.com/docker/docker/blob/eac91a19d632dc82b04f19eb11f83ed1dcefb8ae/cli/command/stack/deploy.go#L40
2. Be able to run the Docker client with the specified file

Unnecessary rows on "All containers" screen

Steps:

• Open /clusters/all

Result:

• Many empty rows are displayed with node status "Node is offline"

Remove dm.config.git.enabled property

dm.config.git.url should be enough for activating cloud config

allow to remove env variable fields in create container dialog (add "-" button to every field)

Implement support of remote TTY

To evaluate approach to add remote TTY via our HTML UI. Note that it may require specific options for run containers & etc.

Fix port mapping for unexposed ports

impossible to log in over https

I use https to access the web interface Haven. and it is impossible to log in.
maybe I'm doing something wrong?

Adjusting of "Node" doesn't work when cloning container

Steps:

• Open /clusters/{cluster}
• Choose a container and select "Clone"
• Change "Node" to any node other then current
• Press "Create container"

Result:

• Container is started on the same node as original what is incorrect

Improve Swarm process heath detection

There are Swarm edge cases that we need to detect and provide user with feedback:

• swarm try to bind to used port
• swarm hang

Non semantic versioning tags should not influence on images updates

Steps:

• Open /clusters/{name}/images

Result:

• Image shouldn't be highlighted because of "latest" image tag

Save json type info in KV.

We load JSON type from Kv, but not do anything for save it.

volumes management

Support for volumes management.
api: https://docs.docker.com/engine/api/v1.25/#tag/Volume

NodeStorage: node registration

Currently we use 'name-address' pair for adding new node. In storage, we use node name by key.

1. The name is specified by user at registration, but in standalone swarm, it is retrieved from the host name. When the user specify the wrong name, it cause can look like the nodes are invalid in the system.

2. Swarm-mode does not use node name for identity and uses different address (port) for managing node via encrypted RPC.

So following changes must be made:

• Check that the user specified name is the same as the host name
• Rewrite system to use independent node IDs (like currently but fix the behavior of the stadalone-Swarm)

Support for secret API

Docker provides a secret API: https://docs.docker.com/engine/api/v1.25/#tag/Secret (in api from 1.25)
doc: https://docs.docker.com/engine/swarm/secrets/

In terms of Docker Swarm services, a secret is a blob of data, such as a password, SSH private key, SSL certificate, or another piece of data that should not be transmitted over a network or stored unencrypted in a Dockerfile or in your application’s source code. In Docker 1.13 and higher, you can use Docker secrets to centrally manage this data and securely transmit it to only those containers that need access to it. Secrets are encrypted during transit and at rest in a Docker swarm. A given secret is only accessible to those services which have been granted explicit access to it, and only while those service tasks are running.

We need to provide support in Haven.

make docker-agent is optional

ConfigsFetcherGitTest is broken

So, we have test that have different behavior in ide and shell, that is not good.

agent container with proxy docker.sock to secured http

At commit d8a7fe0 i start develop of agent module, which must do:

• proxy /var/run/docker.sock to node http port (8771) with optional encryption

It need because current way to expose docker api has issuess:

• docker does not provide way to secure its api (we may use tlsverify, but it complicates configuration)
• some users has difficulties with configuration of docker

Developing of agent achieve us a deploying node by single command like

docker run -v /var/run/docker.sock:/var/run/docker.sock cluman-agent cluman-master-node.local

Allow to chose type of cluster (stand alone swarm or swarm-mode) during creating new cluster

see /swagger-ui.html#!/cluster-api/updateClusterUsingPATCH

was added
"managers": [ "string" ] List of node names which will be used as managers.
and
type: "SWARM"(standalone swarm cluster)/"DOCKER" (docker in swarm-mode cluster).

Improve docker events fetch

Current implementation use scheduledThreadExecutor which configured on fixed thread count, and can not allocate new thread for node. This work incorrect - when node count great than pool size - it can not subscribe to all nodes.

Behavior of data table in application pages are inconsistent

On some pages, the entire section of the page is not rendered until the the data is loaded. On other pages, most of the pages are rendered except for the data that are still being returned from server. The behavior should be consolidated to be the latter where most of the pages are rendered to give user a better experience.

Also if there are no data in a data table, some tables are empty while others show a friendly message. We should always show a friendly message.

help me pls

Simplify upgrading agent

Currently agent uses self signed key pair for ssl, this made upgrading rather difficult. Default installation should be as simple as it possible

Manage cluster networks

Currently we automatically create network per cluster.
We need API for creating custom networks (bridge, overlay, etc.), list existed networks in UI (API exists)

DockerService define caches mutable data & publish docker DTO

Below and some other methods that need to be refactored:

• it must return immutable data
• result must be independent from docker api

Add ability to clone an existing container

I would like to be able to "clone" an existing container but be able to modify the different attributes such as env. variables, volume settings, tags, etc before starting.

Add remove node feature to UI

see: DELETE /ui/api/nodes/{node}

DockerClusterContainers.getContainersInternal load all containers

improve 'add node' UI

add input filed for node IP, and generate command like:

wget --content-disposition "http://$MASTER_IP:8761/discovery/agent/haven-agent.py?node=$SELF_IP:2375"
 chmod +x haven-agent.py

where $SELF_IP - the node ip

Swarm support

Hello , what you mean under "Swarm support"?
Does it needs to install agents on each swarm node, or you have already implemented mechanism to manage swarm cluster via swarm master node (i mean docker swarm usage , not swarm mode)?

I reup haven:

1. stop and rm haven container
2. stop and rm etcd0 container
3. delete data dirs
4. up etcd0 and haven conteiners
