Deploy Base Image

Kubernetes keeps restarting pods whose image is a base image because they don't have an executable that starts a process and keeps that process running.

To deploy a base image you need to set the following values for it

spec.containers.args:
  - sh
spec.containers.stdin: true
spec.containers.stdinOnce: true
spec.containers.tty: true
spec.terminationGracePeriodSeconds: 30

for example of a deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: maven
spec:
  selector:
    matchLabels:
      app: maven
    spec:
      containers:
        - name: maven
          image: maven:3.8.6-jdk-11
          imagePullPolicy: IfNotPresent
          args:
            - sh
          stdin: true
          stdinOnce: true
          tty: true
      terminationGracePeriodSeconds: 30
