Harmonize GitHub issue labels across all repos in the organization?

[brian-rose]

Currently we have to manually create labels such as "High priority" at the repo level, and the badges all end up with different colors.

It would be really useful to harmonize this across repos, especially now that we're using the project board to track work across all repos. Is this easy to do?

[brian-rose]

I will investigate whether this is simple or not.

I manually created new default tags at the organization level following these instructions

I don't think these will automatically propagate down to existing repos though. Probably just affects newly created repos.

I also went through several of our high traffic repos and manually edited the colors of the most important labels:

• high priority #fbca04
• medium priority #fef2c0
• low priority #c2e0c6
• content #0052cc
• infrastructure #006b75

I pulled these colors from https://github.com/ProjectPythia/.github/blob/main/.github/labels.yml where we have a bunch of standard labels defined. But I don't really understand how GitHub interprets this file and whether it's possible to programatically change labels across repos.

[brian-rose]

The harmonization of the colors helps make our project board easier to read, I think.

We could do more of this manual syncing of colors across all repos but it's pretty tedious work.

Nice! Having the appropriate defaults in place for new repos probably addresses the most urgent part of this issue; we could think of dropping the priority for the harmonizing of the existing repos.

[brian-rose]

Makes sense! I will do that.

Looks like I've been trying to reinvent a wheel here.

We actually have this workflow already:
https://github.com/ProjectPythia/.github/blob/main/.github/workflows/labels.yml

which is running hourly and syncing labels from the file https://github.com/ProjectPythia/.github/blob/main/.github/labels.yml to an explicit list of repos.

Seems that the only problem is the list of repos is way out of date. I will open a PR to get it updated.
