Hello guys, what is wrong with this yaml, It looks well with the *volumeMounts* . . .

Hello guys, what is wrong with this yaml, It looks well with the volumeMounts

spec:
  containers:
  - command:
    - /bin/sh
    - -c
    - while true; do date; sleep $TIME_FREQ;done > /opt/time/time-check.log
    image: busybox
    imagePullPolicy: Always
    name: time-check
    resources: {}
    volumeMounts:
    - mountPath: /opt/time
      name: vol
    terminationMessagePath: /dev/termination-log
    terminationMessagePolicy: File
  volumes:
  - name: vol
    emptyDir: {}
  dnsPolicy: ClusterFirst
  enableServiceLinks: true
  nodeName: node01
  preemptionPolicy: PreemptLowerPriority

I am getting this error, when I apply the yaml

controlplane $ k apply -f /tmp/kubectl-edit-xk9a5.yaml -n dvl1987
The Pod "time-check" is invalid: spec.containers[0].volumeMounts[0].name: Not found: "vol"
#2

Tanumoy Ghosh:
Just a guess if vol is a keyword; try changing vol to my-vol and see if it gets applied

#3

Edith Puclla:
I will try

#4

Edith Puclla:
same problem :open_mouth:

The Pod "time-check" is invalid: spec.containers[0].volumeMounts[0].name: Not found: "volll"
#5

Tanumoy Ghosh:
Is this Lightening Lab 1 or 2 ?

#6

Edith Puclla:
Lightening 1 , question 3 I think, time-check pod

#7

Tanumoy Ghosh:
ok - let me try

#8

Edith Puclla:
wohoo!! :dancer:

Tanumoy Ghosh:
Did you create the configmap time-config before creating the pod and why are you explicitly scheduling the pod in node01 ?

For me it worked with vol

$ kubectl create ns dvl1987
namespace/dvl1987 created

$ kubectl -n dvl1987 create cm time-config --from-literal=TIME_FREQ=10
configmap/time-config created

$ kubectl -n dvl1987 run time-check --image busybox --dry-run=client -o yaml -- /bin/sh -c 'while true; do date; sleep $TIME_FREQ;done >> /opt/time/time-check.log' > busybox.yaml

$ vi busybox.yaml
apiVersion: v1
kind: Pod
metadata:
  creationTimestamp: null
  labels:
    run: time-check
  name: time-check
  namespace: dvl1987
spec:
  containers:
  - args:
    - /bin/sh
    - -c
    - while true; do date; sleep $TIME_FREQ;done >> /opt/time/time-check.log
    image: busybox
    name: time-check
    resources: {}
    volumeMounts:
    - mountPath: /opt/time
      name: vol
  volumes:
  - name: vol
    emptyDir: {}
  dnsPolicy: ClusterFirst
  restartPolicy: Always
status: {}

$ kubectl create -f busybox.yaml 
pod/time-check created

Tanumoy Ghosh:
I have copy pasted your spec section it is working fine at my end in Kodekloud Lab environment

#11

Edith Puclla:
I see @Tanumoy Ghosh I was editing this pod, so maybe I got confused :blush:
I did it again, and It works too.
Thank you so much
