  name: random-logger
spec:
  selector:
    matchLabels:
      app: random-logger
  template:
    metadata:
      labels:
        app: random-logger
    spec:
      containers:
  - name: random-logger
    image: chentex/random-logger:latest
    command: ["sh", "-c",  "./entrypoint.sh &> /logfile"]
</code>
  

    
      $ kubectl logs random-logger-76c6fd98d5-8d5fm
</code>
  

    
      $ kubectl exec random-logger-76c6fd98d5-8d5fm cat /logfile
