Use server-managed user SSH keys for new runs#3216
Merged
Conversation
This commit updates the CLI and the server to use
server-managed user SSH keys when starting new
runs. This allows users to attach to the run from
different machines, since the SSH key is
automatically replicated to all clients.
Implementation details:
- Server:
- If the user key is missing, generate it when
the user first calls `/get_my_user`.
- Client:
- Before applying or getting a run plan, call
`/get_my_user` to check if the user key is
available. If it is, use it.
- Cache the downloaded keys in `~/.dstack/ssh`
to avoid repeated `/get_my_user` calls.
- Switch from `warn` to logger messages, since
this code is part of the Python API, so its
output should be configurable.

Why put UserSSHKeyManager in core instead of api?
