feat(wpcarro/terraform): Support SSH r/3498
Supporting SSH turned-out to be a bit of a saga... Thank you @espes and @grfn for the pointers. Problem: When I originally setup my Google VM, I followed this tutorial, https://nixos.wiki/wiki/Install_NixOS_on_GCE, so I ended-up installing `nixos-20-03`: an older version of NixOS, (the newest version in `gsutils ls -l gs://nixos-images`). Critically, I missed this important footnote: > NOTE: Newer images (from 20.09 on) won't be available at the bucket above, and > will instead need to be found at > <nixpkgs/nixos/modules/virtualisation/gce-images.nix>. It turns out that *newer* images include this script... https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/virtualisation/fetch-instance-ssh-keys.bash ...which reads the key, "sshKeys", from the Google metadata server and copies the value into /root/.ssh/authorized_keys. To make matters a bit misleading, the NixOS script expects the key to be "sshKeys", but Google deprecated that in favor of "ssh-keys" (hence why both versions appear in this commit). TL;DR: - upgrading to a newer NixOS image - adding an empty access_config block so Google will assign my VM an external IP - removing oslogin (not necessary to do, and I may add it back later) - adding my public SSH key as metadata Change-Id: If624fe77afd47b31fa7be0a1dd4a55512317eef0 Reviewed-on: https://cl.tvl.fyi/c/depot/+/4737 Tested-by: BuildkiteCI Reviewed-by: wpcarro <wpcarro@gmail.com> Autosubmit: wpcarro <wpcarro@gmail.com>
