在kubernetes集群上部署zuul代理

Question

I have a Kubernetes cluster configured on Linux. On this, I want to configure zuul proxy. For deploying zuul, I am using zuul docker images from docker hub. But after running these zuul images, the pod status shows as 'ImagePullBackOff'. I used 2-3 repositories but all are showing the same status. I am either using 'kubectl create' or 'kubectl run' to install & configure zuul proxy. Can anybody let me know how can we install & configure zuul proxy on kubernetes cluster either by using docker images or any other method ?

It seems you are trying to get netflixoss/zuul image, ie netflixoss/zuul:latest but get the following error:

  Warning  Failed                 15s               kubelet, minikube  Failed to pull image "netflixoss/zuul": rpc error: code = Unknown desc = Error response from daemon: manifest for netflixoss/zuul:latest not found
  Warning  Failed                 15s               kubelet, minikube  Error: ErrImagePull
  Normal   BackOff                14s               kubelet, minikube  Back-off pulling image "netflixoss/zuul"
  Warning  Failed                 14s               kubelet, minikube  Error: ImagePullBackOff
  Normal   Pulling                0s (x2 over 18s)  kubelet, minikube  pulling image "netflixoss/zuul"

That's because there is only one version 1.0.28 available for image netflixoss/zuul . There is no default latest version for the image.

So, you need to deploy netflixoss/zuul:1.0.28 image on your kubernetes cluster:

kubectl run --image netflixoss/zuul:1.0.28 zuul

It is successfully pulled:

  Normal  Pulled                 10m   kubelet, minikube  Successfully pulled image "netflixoss/zuul:1.0.28"
