What happens if you change the docker image in a cluster?

How severe does this issue affect your experience of using Ray?

  • Low: It annoys or frustrates me for a moment.
    • Would be useful to make a decision on whether to bake docker images into the AMIs.

I’m wondering; if I update the worker image name in a ray cluster, and then re-run ray up, will Ray kill the old containers and spawn new containers with the updated images?

Yes, in fact, generally when the config for a node changes, for safety, the entire node is removed and re-added.
