kubernetes deploy plugin in Jenkins doesn't update pod

I use kubernetes-cd plugin in Jenkins (https://plugins.jenkins.io/kubernetes-cd/) to deploy my application successfully.

enter image description here

But, I got a problem, when I re-run the job again, the jenkins doesn't update my pod (doesn't delete and create new pod again), so my changes of code aren't affected. And after I delete the pod manual using kubectl commands in kubernetes cluster and re-run the job, it make changes

Below is my yaml file. Do you know how to fix this ?

    app: tds-upload

There are different ways to make Kubernetes deploy new changes.

  1. kubectl rollout restart deployment myapp

This is the current way to trigger a rolling update and leave the old replica sets in place for other operations provided by kubectl rollout like rollbacks

  1. kubectl patch deployment my-deployment -p "{\"spec\":{\"template\":{\"metadata\":{\"labels\":{\"build\":\"$CI_COMMIT_SHORT_SHA\"}}}}}}"

Where you can use any name and any value for the label as long as it changes with each build.

You can use the kubectl cli plugin of Jenkins to execute above commands.
