How to trigger a kubernetes/openshift job restart when ever a specific pod in the cluster will restart?

For example, I have a pod running a server in it and I have a job in my cluster that is doing some yaml patching on the server deployment.

Is there a way we can set up some kind of trigger or anything that will rerun the job when ever the respective deployment change happens?

You can add your job spec into the deployment as initContainer like that:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: example
spec:
  replicas: 1
  selector:
    matchLabels:
      app: example
  template:
    metadata:
      labels:
        app: example
    spec:
      initContainers:
      - name: init
        image: centos:7
        command:
        - "bin/bash"
        - "-c"
        - "do something useful"
      containers:
      - name: nginx
        image: nginx

In this case every time you rollout the deployment, job defined in initContainers will run.
