autopull

Bash script that auto-creates Pull Requests for a given repo.

How it works

1. Clones the to-be-updated repo (AP_REPO) into a tmp dir
2. Does stuff (AP_CMD)
3. Creates a PR for the changes
4. Profit!

Configuration

This script uses environment variables for configuration; most must be set. Examples are from the ZoneDB project, which updates its data daily.

• AP_REPO — GitHub repository to auto-update, in the form of user/repo, e.g. zonedb/zonedb
• AP_BRANCH — Branch to check out. Default: master
• AP_SETUP_CMD — Optional command to run before running the update command, e.g. for installing dependencies.
• AP_CMD — Update command that mutates the repository. Default: make update
• GH_USER — GitHub username (yours or a bot)
• GH_TOKEN – GitHub access token (not your password!)
• GIT_AUTHOR_NAME and GIT_COMMITTER_NAME — Name of the user or robot doing the committing. Both must be set.
• GIT_AUTHOR_EMAIL and GIT_COMMITTER_EMAIL — Email address of the user or robot doing the committing. Both must be set.

Heroku quickstart

1. Clone (or fork) this repository
2. Create a Heroku app, which will run the autopull script
3. Set the above environment variables
4. Add the Heroku Scheduler add-on: heroku addons:create scheduler:standard
5. Configure the work schedule: heroku addons:open scheduler and command to run (./autopull)
6. Push your fork to Heroku: git push {your Heroku app's git remote}
7. Test: heroku run ./autopull -a {your Heroku app name}

Python example

• AP_CMD — python3 script.py
• AP_SETUP_CMD — pip3 install -r requirements.txt
