Pardon my lack of knowlegde.  
If I understand correctly when using Cluster Launcher I have and option to set file\_mounts and it syncs files to all nodes and then I can use ‘ray rsync-down’ to download files from Cluster head.

How could I do those things while the using Cluster Operator instead of Cluster Launcher?

This is a great question - syncing files up can be handled using the “working\_dir” setting of Runtime environments.

Syncing files up can be handled using the working\_dir setting of runtime environments:  
[https://docs.ray.io/en/master/advanced.html#runtime-environments-experimental](https://docs.ray.io/en/master/advanced.html#runtime-environments-experimental)

I don’t think we currently have a built-in answer for syncing files down.  
I’ve opened a feature request:

> \### Describe your feature request
> 
> The deprecated K8s cluster launcher support…ed syncing files from cluster to laptop, but the operator does not.

> We may want a Ray-internal system for syncing files/directories down and between nodes.

Come to think of it, `kubectl cp` is an option here.
