host forgejo on fly.io

original guide: https://lugh.ch/forgejo-on-flyio.html#should-you-self-host-your-git-instance

Dockerfile is vanilla forgejo (the guide uses the rootless version)

setup

• see fly.toml for all the env vars
• in the original guide most of the FIXMEs are straightforward (don't make the two cookie names the exact same)
• the FIXMEs below (in the admin script)
  • initial guide didn't mention ROOT_URL (which is probably of interest to most!)

create the initial user (admin)

• fly ssh console (be fast before the scale to 0 kicks in... haha)
• su git (git user owns the files already there)
• forgejo admin user create --username FIXME --password FIXME --email "some@email" --admin
  • if needed (config file is not found), you can add something like --config custom/conf/app.ini (take note of the app.ini, you can find . | grep app.ini)

maintenance

ssh/scp to grab backups

• fly ssh issue (temp ssh creds)
• fly ssh console (use the creds)
• su - git

forgejo dump \
  --config /var/lib/gitea/custom/conf/app.ini \
  --type tar.gz \
  --file /var/tmp/forgejo_$(date +%Y%m%d_%H%M%SZ).tar.gz

• scp -i ~/.ssh/MY_KEY root@<APP_NAME>.internal:/var/tmp/forgejo\* . (from wherever!)
• fly ssh rm -r /var/tmp/forgejo* remove the backup archive on the machine (don’t wanna trigger an auto disk resize)
