Automate Prs to keep submodules up to date.

Submarine

This program iterates over a list of 'consumer' github url's looking for submodules. When it finds a match, it checks the current commit sha of the submodule repo against the commit of the submodule in the consumer repo. If they differ, and there is no matching open PR, the repo is cloned and a commit is created on a new branch and pushed to the remote. A PR is then created.

Pre-reqs

If you are comfortable setting up python virtenv and willing to export env vars by hand, you can skip installing direnv. But it really makes things easier...

• install direnv direnv is used to setup the python environment and export required environment variables.

• Create an access token in github

Setup

Create config/list.txt as shown below and update it with one or more repos containing submodules. You can choose which submodules are checked.

  $ cp envrc.example .envrc
  $ direnv allow
  $ direnv edit .envrc
  # update this line with your github access token.
  # export GITHUB_TOKEN="_YOUR_GITHUB_ACCESS_TOKEN_"

  $ mkdir config
  $ cp list.txt.example config/list.txt

  $ pip install pygithub

Run

  $ ./submarine.py

Production

Add a crontab entry to run the script at the desired interval. Given the requirements, this is a bit tricky. Googling will reveal some ways to run tasks every N weeks using a wrapper script.

If you have ssh access to production servers/containers, this above command can be manually run as needed.
