[BUG] SSH private key not found
I run the basic example and get this:
❯ uc machine init kali@orb
Error: SSH login to remote machine kali@orb: read private key file "/Users/alper/.ssh/id_ed25519": open /Users/alper/.ssh/id_ed25519: no such file or directory
That is true because my key is called .ssh/alper.pub
Is this hardcoded somewhere?
This is the default key path used if you don't specify any. From the uc machine init --help:
-i, --ssh-key string Path to SSH private key for remote login (if not already added to SSH agent). (default "~/.ssh/id_ed25519")
You can specify it explicitly with uc machine init kali@orb -i ~/.ssh/alper.pub. Although it seems alper.pub is the public key, you need to specify the path to your private SSH key (identity).
Alternatively, add your ssh key to the local SSH agent with ssh-add path/to/key so you don't need to specify it for machine init/add commands.
I'm hitting this error and specifying the key isn't working.
The key is in my agent, it gets me into my host, and my host has passwordless sudo enabled. I also tried root@ but got the same results.

@spiffytech as you likely already discovered, the SSH configuration (.ssh/config) is not supported at the moment and will be supported after finishing the implementation of ssh+cli:// targets: https://github.com/psviderski/uncloud/pull/173, https://github.com/psviderski/uncloud/pull/152. We're planning to make this the default in the future releases.
