      - name: somename
        image: image

Answer 1

You should be using a shell as an entrypoint for that, e.g.:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-deployment
  labels:
    app: xyz
spec:
  replicas: 3
  selector:
    matchLabels:
      app: xyz
  template:
    metadata:
      labels:
        app: xyz
    spec:
      containers:
      - name: somename
        image: image
        command: ["sh"]
        args: ["-c" , "source /vault/secrets/keystoreinfo && exec java -Djava.security.egd=file:/dev /.urandum -jar /app.jar"]
        ports:
        - containerPort: 80
