Update pod configuration for running pod

I would like to update image version for my running kubernetes pod.

My current config is:

spec:
  containers:
    - name: ADMIN_USER
      valueFrom:
        secretKeyRef:
          key: jenkins-admin-user
          name: jenkins
    image: jenkins/jenkins:latest

I would like to update it to

spec:
  containers:
    - name: ADMIN_USER
      valueFrom:
        secretKeyRef:
          key: jenkins-admin-user
          name: jenkins
    image: jenkins/jenkins:2.247

I have tried to run an apply as I understood by reading documentation kubectl apply -f jenkins.yaml --namespace=infrastructure, but nothing changed (nor my pod was restarted automatically).

Can someone advice how to do this?

You can use replace

kubectl replace -f jenkins.yaml --namespace=infrastructure

Probably image: jenkins/jenkins:2.247 is the same as image: jenkins/jenkins:latest and because of that, no update occurred.

Tip: Try to not use latest tag but to set the specific tag always.
