For anyone looking to add commit signing (GPG)

[ericsizemore]

Hello all.

Wasn't sure if this was the correct category; my apologies if not. I did perform a search but didn't come up with anything related to this, other than issue #132

I was using another action to add and commit until recently, when it started experiencing issues with my branch protection rules. I came across this action and decided to give it a try. I wanted to share a recent workflow update that, thus far, appears to be working for signing commits with a GPG key. I would imagine it could be tweaked, as I am not that well versed with GitHub actions as I would like. There are few things to note:

1. I created a Personal Access Token to be used specifically with this workflow. (secrets.PAT)
2. This relies on you having your GPG key added to GitHub
3. I created two repository secrets for the GPG secret key and passphrase. (https://github.com/yourusername/yourrepo/settings/secrets/actions/new : secrets.GPG_PRIVATE_KEY, secrets.GPG_PASSPHRASE)
4. I had to enable Allow force-pushes under my branch protection rules. I also enabled Specify who can force push with myself listed.
5. steps.import-gpg.outputs.name and steps.import-gpg.outputs.email will use the information tied to the GPG key. Of course, the key you use should match the name and email address on your GitHub account.

           skip_fetch: true

You can see the workflow run for this here. You can see the resulting commit here which shows me as the author and that it is Verified.

Lastly, it is currently 8am and I'm running on little sleep :D If you notice any issues, or have suggestions, please let me know! I hope this helps someone that was struggling much like I was.

Regards,
Eric
