More self-hosting work this weekend:
I have seven open source projects currently hosted on GitHub; eventually I'll move them off, but that will take some effort. However, all of them have CI workflows which produce OCI (container) images which are used to run linters and tests (so that those operations will run more quickly and repeatably), and I'd been hosting those images on quay.io.
This weekend I reconfigured those processes to publish and consume images hosted on my Forgejo server (using its 'Packages' feature), and deleted my account on quay.io. I have a Fastly Delivery (CDN) service in front of Forgejo, so I had to do some learning about how to make that work, which I'll get published in a blog post Real Soon Now.
Images are now live at https://forge.km6g.us/km6g/-/packages, and while I haven't done a scientific experiment, it appears that the Actions jobs which use these images actually start faster than when the images were on quay.io.
