Trying to create liveness command with exec-liveness.yaml.

kubectl create -f exec-liveness.yaml

apiVersion: v1
kind: Pod 
metadata:
  labels:
    test: liveness
  name: liveness-exec
spec:
  containers:
  - name: liveness 
  image: k8s.gcr.io/busybox
  args:
  - /bin/sh
  - -c
  - touch /tmp/healthy; sleep 30; rm -rf /tmp/healthy; sleep 600
  livenessProbe:
    exec:
      command:
      - cat
      - /tmp/healthy
    initialDelaySeconds: 3
    periodSeconds: 5

Do I try to fix the errors, or turn off validation?

Hi Paul,

The indentation is wrong.

The stuff after this line relates to the container so should be indented to line up with name

Kind regards,
Stephen

Looks lined up to me.

I have since copied the file from the Kubernetes docs and it worked. thanks

Just for reference, this is what I meant about indenting to be inline with name

containers is an array of container specs objects, and each objectis indented with a -, so for example if the pod had 2 containers it would look like:

spec:
  containers:
  - name: container1
    image: image1
    livenessProbe:
      exec:
        command:
        - cat
        - /tmp/healthy
      initialDelaySeconds: 3
      periodSeconds: 5 
  - name: container2
    image: image2

Kind regards,
Stephen
