Kubernetes integration with Netflix OSS
I'm wrapping my head around how to get this tool into our configuration management. What I'm looking for:
a. Have a defined and fixed version of all libraries deployed (no snapshots).
b. Use defined and fixed version of all maven plugins (or skip them all together and use dockerfiles directly if possible)
b. Skip all examples. Only deploy turbine, appropriate discovery modules and hystrix dashboard.
c. Use internal docker repo.
d. Rely on published builds through maven central (no local build/test).
Any thoughts?
I tried out the hello-hystrix example. I scaled up the pods to 6 instances. But when deploying hystrix-dashboard and turbine-server I only see 1 host on the dasboard and the turbine stream also shows "reportingHostsLast10Seconds":1. Alhough in the turbine logs I can see that 6 hosts were discovered.
I ran the example on my local minikube.
Thanks,
Thorsten
Hi,
I have a use case where we would like to deploy a hystrix console + turbine inside an OpenShift cluster to monitor hystrix sources that reside outside the cluster.
Is it possible to specify which turbine discovery policy to use?
Thanks

along with a docker/kubernetes packaging of the zipkin console
Cannot see any ribbon related code on kubeflix/examples/hello-world/hello-ribbon-springboot/
I see hystrix things but nothing on ribbon.
Not sure what version of the Jetty 9 base image fabric8/hystrix-dashboard:1.0.26
is using, but I hit permissions issues on OpenShift. Seems ok if I build & deploy using fabric8/jetty-9:1.1.10
as the base image.

I also enabled some services by annotating them:

hystrix.enabled: "true"
hystrix.cluster: "svc1"
I'm not sure where I should put them, though. Should it be in the service or in the deployment?
Anyways, by doing this, I can access the turbine-server
ELB addr + /turbine.stream
, but, if a append a ?cluster=svc1
in the URL, I get a 404.
Seems like I'm missing some turbine configs, but I'm not sure how to do it and there is no example in the docs...
Thanks!
so that it is properly shown in the fabric8 console.
See fabric8io/fabric8#5920 for details.

Hi, currently it is assumed that the pods that are hystrix stream sources will have the hystrix.enabled
label.
This may impose unnecessary constraints on the source pods. There could also be situations where multiple turbine serves need to be run in the same kubernetes cluster and there would be no way to specify which pods each turbine server should connect to.
I'd like to propose the following improvements:
hystrix.enabled
if no selector is specified. A selector can match on multiple labels.I should be able to provide 1 and 2 based on my previous project.
3 is not urgent for me and my current endeavor but I think it would be useful in the long term
4 goes together with 3 but I'm afraid there is no easy way to do it unless upgrading to turbine 2.x, which wasn't very mature last time I looked at it.
I got the hello-hystrix example working in my vagrant sandbox, but couldn't get them working in my own k8 cluster with the same exported docker images.
I curled the turbine server and only got the heartbeat, it appears the turbine server is not finding any valid streams. Can you guys help check my labels? Anything needed besides "hystrix.enabled: true"? also is there any other config required inside the turbine server? what else do i need to check?

I was getting the following error when trying to build the broker application under the loan broker example:

I changed the pom to include the current version for the ribbon-discovery dependency which allowed the build to go through.
<dependency>
<groupId>io.fabric8.kubeflix</groupId>
<artifactId>ribbon-discovery</artifactId>
<version>1.0.26</version>
</dependency>
can someone list the dependencies for this project? The instructions are very brief, following it does not lead to successful builds
I am getting this error which i assume is because i don't have fabric8 installed. [ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.14.2:build (default-cli) on project turbine-server: Execution default-cli of goal io.fabric8:docker-maven-plugin:0.14.2:build failed: No url given, no DOCKER_HOST environment variable and no read/writable '/var/run/docker.sock' -> [Help 1]
I tried to build it's failed.
I am not a developer, purely Infra guy.
Is it possible create docker images of all containers and push to docker hub so people can use easyly.
Anyway it's a nice example.
Thanks in advance.

verify by running the demo and watching the hystrix circuit breaker report 100% failures. noticed this in demo @rajdavies and @jstrachan and i did this morning.
I have a fix coming in a sec.
looks like kubeflix is using a really old version of kubernetes-client. Upgrading caused issues with mockwebserver - so maybe that needs to migrate to the io.fabric8 one?
Not totally sure - figure @iocanel you'd know better :)
has anyone been able to get the turbine discovery working out side the fabric8 sandbox?
Hi,
I'm working with OpenShift 3.1 which aligns with kubernetes 1.1.
It looks like the new spring based framework requires configmaps to be available.
I'd like to request configmaps to be optionals and that the application starts even if they are not available
Thanks
Raffaele
I have taken your example zuul-proxy, and modified it for my own use.
I'm having issues getting the namespace to be set when looking up endpoints exposed through zuul.
I can see the services being mapped to ZuulController.
When I try to hit those mapped URL paths, I see an error in the logs:
KubernetesServerList : Did not find any endpoints in ribbon in namespace [null] for name [xxxx] and portName [xxxx]
The name and portName are correct based on the URL being used, and the configuration.
What am I missing to get the namespace set?
Hello all,
I am try to run this sample but I got those error when access the ribbon service in kubernetes:
kubectl get services:
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
hello-hystrix 10.0.0.162 80:32210/TCP 6m
hello-ribbon 10.0.0.26 80:32199/TCP 6m
kubernetes 10.0.0.1 443/TCP 7m
Url: http://192.168.99.100:32199/hello
if I try access br hello-kystrix services its works fine.
I tryed google about those error, but I got no response.
Someone has any idea about what those error??
Thanks,

Can we have a configuration to change the environment to openshift for turbine?
1.4.13 does not have this issue.

hi,
there should be a way to specify where the hystrix stream can be found for the observed pods.
Not all webapps will have the hystrix stream at /hystrix.stream
For example many webapps will have a context root before that.
I started a similar project to what you're doing here and stopped when I saw that you guys where going to provide "official" support. I had solved this problem, you may want to take a look: https://github.com/raffaelespazzoli/hystrix-kuberneters-instance-discovery
thanks
Raffaele
I am trying to run the loanbroker sample but the services are failing to start. An example from the credit bureau is below. Please help been trying to stand this up as an example on using kubeflix over the naive Spring cloud approach but cannot get past this one.
Thanks,
Andrew

it'd be great to create a quickstart for folks wanting to write a microservice based on spring boot + RestTemplate + hystrix so we can do demos showing how to get started with kurbine and then run turbine etc
Adding a quickstart to this github organisation should do the trick:

Folks might want to use Zuul to implement load balancing across multiple services using %age weightings etc. So it might be nice to support a Zuul plugin to do endpoint discovery for services Zuul talks to.
Ideally ingress in kubernetes will hopefully be a more natively supported option; but having Zuul support in kubeflix will let folks familiar with Zuul feel right at home
