Use local docker image?

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

I see that I can use a predefined Docker image when launching a Ray cluster. I was wondering, if I want to use my own Docker image, do I need to upload it to a Docker repository. Or, is it fine if the Docker image is just stored locally on my own computer?

the ray nodes just need to be able to docker run the image. It could be “local” in the sense that it’s already on the node (maybe baked into the machine image, or docker build on the machine) but it does need to find its way to the nodes of the cluster.
