I'm newbie of the Kubernetes while I'm using Google Cloud Container. I just follow the tutorials as belows:
https://cloud.google.com/container-engine/docs/tutorials/http-balancer http://kubernetes.io/docs/hellonode/#create-your-pod
In these tutorials, I'll get the replicacontroller after I run the "kubectl run" but there is no replicacontrollers so that I cannot run the command of "kubectl expose rc" in order to open a port.
Here is my result of the commands:
ChangMatthews-MacBook-Pro:frontend changmatthew$ kubectl run nginx --image=nginx --port=80
deployment "nginx" created
ChangMatthews-MacBook-Pro:frontend changmatthew$ kubectl expose rc nginx --target-port=80 --type=NodePort
Error from server: replicationcontrollers "nginx" not foundHere is my result when I run "kubectl get rc,svc,ingress,deployments,pods":
ChangMatthews-MacBook-Pro:frontend changmatthew$ kubectl get rc,svc,ingress,deployments,pods
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes 10.3.240.1 <none> 443/TCP 12m
NAME RULE BACKEND ADDRESS AGE
basic-ingress - nginx:80 107.178.247.247 12m
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
nginx 1 1 1 1 11m
NAME READY STATUS RESTARTS AGE
nginx-198147104-zgo7m 1/1 Running 0 11mOne of my solution is to create yaml file which define the replicacontroller. But is there any way to create replicacontroller via kubectl run command like above tutorials?
Thanks,
Now that kubectl run creates a deployment, you specify that the type being exposed in a deployment rather than a replication controller:
kubectl expose deployment nginx --target-port=80 --type=NodePortThe team might still be updating the docs to reflect 1.2. Note the output you got:
$ kubectl run nginx --image=nginx --port=80
deployment "nginx" created
kubectl run now creates a deployemtn+replica-set. To view these you can do kubectl get deployment, and get rs respectively. Deployments are essentially a nicer way to perform rolling update server side, but there's a little more to it. See docs: http://kubernetes.io/docs/user-guide/deployments/
