## Setting up git user for use with gitea originally
```sh
sudo -u git ssh-keygen -t rsa -b 4096 -C "Gitea Host Key"
sudo -u git cat /home/git/.ssh/id_rsa.pub | sudo -u git tee -a /home/git/.ssh/authorized_keys
sudo -u git chmod 600 /home/git/.ssh/authorized_keys
```
`/home/git/.ssh/authorized_keys` should look like this:
```txt
# SSH pubkey from git user
ssh-rsa <Gitea Host Key>
# other keys from users
command="/usr/local/bin/gitea --config=/data/gitea/conf/app.ini serv key-1",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty <user pubkey>
```
To point gitea/forgejo to the shim gitea binary for SSH I symlink the current system version to `/usr/local/bin/gitea`.
```sh
ln -s /run/current-system/sw/bin/gitea /usr/local/bin/gitea
```
## Setting up Attic
Generated a key using command provided in attic docs:
```sh
nix run nixpkgs#openssl -- genrsa -traditional 4096 | base64 -w0
```
And wrote `ATTIC_SERVER_TOKEN_RS256_SECRET_BASE64="output from above"` to `/etc/attic.env`
I generated a token to configure the caches using the following command:
```
atticd-atticadm make-token --sub daylin --push "*" --pull "*" --validity '1y' --create-cache "*" --configure-cache "*" --configure-cache-retention "*" --destroy-cache "*" --delete "*"
```
If I handled secrets via `sops` or `agenix` I think this could be stored directly in the repo.
I also had to modify the firewall so that docker would forward along the requests by caddy to `host.docker.internal` correctly.
