Doesn't install Docker on server (Hetzner)

[shafy]

I've created a new Hetzner VM (Ubuntu 22.04, AMD) and would expect MRSK to install Docker on the remote machine. However, mrsk deploy fails with:

Acquiring the deploy lock

My SSH key does have root access. After installing Docker manually this problem goes away.

According to the MRSK source, not having Docker installed and failing to install Docker should show an error message. However, this doesn't happen in my case.

Any ideas?

try "mrsk setup" first and later "mrsk deploy"

This solves this issue, thanks! However, this is not made clear in the docs. In fact, there it is implied that mrsk deploy installs Docker.

We should update the docs to reflect that. Or is this a bug, and deploy is supposed to also call invoke "mrsk:cli:server:bootstrap" ? Let me know what the intention is @dhh and I'm happy to make a PR.

Should add a note to docs about it.
