Permission denied deploying Hystrix Dashboard 1.0.26 image on OpenShift

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.

support kubernetes service discovery inside Zuul?

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

new archetype for spring boot + hystrix we can include in the fabric8 forge wizard

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:

Unable to connect to Command Metric Stream. (with Kubeflix 1.0.16 and 1.0.17)

When I deployed Kubeflix 1.0.16 that uses openzipkin/zipkin-query:1.39.3 image I just see the following messages when I open the hystrix-dashboard:

• Unable to connect to Command Metric Stream.
• Unable to connect to Thread Pool Metric Stream.

In the Turbine Pod log I see a lot of exceptions:

turbine discovery question

has anyone been able to get the turbine discovery working out side the fabric8 sandbox?

using kubeflix to monitor hystrix sources from outside the kubernetes cluster

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
Raffaele

improvement to the pod selection logic

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:

1. ability to specify a selector (as in Kubernetes' pod selector) to select the hystrix source pods. We can still default to hystrix.enabled if no selector is specified. A selector can match on multiple labels.
2. ability to specify an hystrix cluster for the defined selector. If no cluster is specified that the cluster name could be the pod name (probably more discussion needed here).
3. ability to specify multiple selectors. With this multiple groups of pods would be selected and would report to the same turbine server.
4. ability to specify a different URL suffix for each selector.

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.

turbine: how to make clusters work

I've tried to make the ?cluster=blah work, but it won't. I'm pretty sure I'm missing something, but I'm not really sure what.

So far, I'm creating everything with this yaml:

---

---
apiVersion: "extensions/v1beta1"

  selector:
    project: "turbine-server"
    provider: "fabric8"
    group: "io.fabric8.kubeflix"
  type: "LoadBalancer"

I also enabled some services by annotating them:

apiVersion: v1
kind: Service
metadata:
  labels:
    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!

Set fabric8-deploy profile in examples, turbine-server and hystrix dashboard

Support for Openshift

Can we have a configuration to change the environment to openshift for turbine?

Fixed version build without examples

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?

ribbon client side load balancer should filter out pods that are not 'Ready'

so we get to reuse the readiness probe results

Unable to build the loan broker example

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

[ERROR] Failed to execute goal on project loanbroker-broker: Could not resolve dependencies for project io.fabric8.kubeflix.examples:loanbroker-broker:jar:1.0-SNAPSHOT: Failure to find io.fabric8.kubeflix:ribbon-discovery:jar:1.0-SNAPSHOT in https://repo.spring.io/libs-release was cached in the local repository, resolution will not be reattempted until the update interval of spring-releases has elapsed or updates are forced -> [Help 1]

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>

Add <description> to pom

so that it is properly shown in the fabric8 console.

See fabric8io/fabric8#5920 for details.

Unable to run the loan broker example on a K8 cluster

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

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.

exported docker image but didn't work

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?

$ kubectl get svc hello-hystrix -o yaml

demo using @HystrixCommand annotation on java code with a fallback method

e.g. like this demo
https://github.com/nklmish/microservice-demo/blob/master/catalog-service/src/main/groovy/com/nklmish/cs/catalogs/integration/ProductBuilder.groovy#L23-L29

Zuul Proxy: SSLException: Unrecognized SSL message, plaintext connection

upgrade the kubernetes-client and mockwebserver/groovy/spock dependencies

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 :)

Modify the hystrix dashboard so that it defaults to the k8s turbine server.

project dependencies

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.

create a demo of using Zipkin service tracing

along with a docker/kubernetes packaging of the zipkin console

ribbon discovery for the credit-bureau doesn't work

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.

Hystrix dashboard v 1.4.9 buggy

Netflix/Hystrix#827

1.4.13 does not have this issue.

":"kubeflix","project":"kubeflix","provider":"fabric8","version":"1.0.20"}:selectordoes not match templatelabels Error from server: Deployment.extensions "turbine-server" is invalid: spec.template.metadata.labels: Invalid value: {"group":"io.fabric8.kubeflix","package":"kubeflix","project":"kubeflix","provider":"fabric8","version":"1.0.20"}:selectordoes not match templatelabels``

specifying the hystrix stream url

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

Namespace issue using zuul-proxy as a basis for a zuul proxy in kubernetes

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?

Meanwhile both hello-hystrix and hello-ribbon-spring-boot are running like specified.

reportingHostsLast10Seconds always 1

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

HttpRequestTemplate should not be created for each request in ribbon example

Docker image

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.

kubeflix not working with kubernetes 1.2

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
