How do I update kubernetes deployment image and command?

Question

I see that I can use the \"kubectl set image\" command to update a container used in a deployment, like this:

kubectl set image deployment/myapp myapp=repo.mycom

You could use kubectl patch for that. Run kubectl patch --help to get the docs, but as far as I can tell something like this should do it:

$ kubectl patch deployment  -p '
spec:
  template:
    spec:
      containers:
        - name: 
          command: ["new", "command"]
'
