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

- **Low**

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.
