How to get the same output with go-template as kubectl get pod output

5/2/2020

I want to get kubectl get pod outputs with go-template. I don't know the way as kubectl get pod -o yaml(json) does not contain READY values (e.g. 1/1)

kubectl get pod
NAME           READY   STATUS    RESTARTS   AGE
client-qfr4s   1/1     Running   0          14d

My purpose is to get additional values (e.g. container-port) in addition to default columns (NAME, READN, STATUS etc.) with one time kubectl command.

kubectl
kubernetes

You can add custom column in kubectl get command like following

    $ kubectl get pods -o custom-columns=NAME:.metadata.name,STATUS:.status.phase,RESTARTS:.status.containerStatuses[].restartCount,CONATAINER_NAME:.spec.containers[*].name,PORT:.spec.containers[*].ports,READY:.status.containerStatuses[*].ready
NAME                         STATUS    RESTARTS   CONATAINER_NAME   PORT                                            READY
nginx-6bc98f4797-7kv6m       Pending   0          busy,nginx        [map[containerPort:8000 protocol:TCP]]          false,true
nginx-6bc98f4797-zv4sp       Pending   0          busy,nginx        [map[containerPort:8000 protocol:TCP]]          false,true

Instead of using get, you can use describe

kubectl describe pod

You will get complete status like below :

Conditions:
  Type              Status
  Initialized       True
  Ready             True
  ContainersReady   True
  PodScheduled      True
