can i use a configmap created from an init container in the pod

Question

I am trying to \"pass\" a value from the init container to a container. Since values in a configmap are shared across the namespace, I figured I can use it for this purpose. Her

You can create an EmptyDir volume, and mount this volume onto both containers. Unlike persistent volume, EmptyDir has no portability issue.

apiVersion: batch/v1
kind: Job
metadata:
  name: installer-test
spec:
  template:
    spec:
      containers:
      - name: installer-test
        image: installer-test:latest
        env:
        - name: clusterId
          value: "some_cluster_id"
        volumeMounts:
        - name: tmp
          mountPath: /tmp/artifact
      initContainers:
      - name: artifactory-snapshot
        image: busybox
        command: ['/bin/sh', '-c', 'cp x /tmp/artifact/x']
        volumeMounts:
        - name: tmp
          mountPath: /tmp/artifact
      restartPolicy: Never
      volumes:
      - name: tmp
        emptyDir: {}
