• Create an account on fly.io if you don't have one.
• Edit the fly.toml files in the root and in docker-daemon and replace the instances of <app_name> to be the name you want.
• Run fly launch --no-deploy in the root dir and accept the fly.toml config that is already there
• Set up the volume fly volumes create gitea_data -s 10, replace 10 with however many GB you want the volume to be. It can be expaned later.
• Run fly deploy
• Go to your new app and set up your gitea account
• On admin settings > actions > runners get your runner token from the create new runner button
• Go to the .dockercmd file and replace <token> with the token you copied
• cd docker-daemon
• fly launch --no-deploy and create another volume fly volumes create <app_name>_data -s 10
• fly ssh console and run the docker run command from the .dockercmd file to start your runner

Congrats. You now have a gitea instance that can run gitea actions.

For more setup go to renovate_config and clone it into your gitea instance to run a dependabot like job.

Once this is set up you can also clone this repo into your gitea instance and it will deploy itself when changes are made to configs.
