Replacing Kaniko with Buildah in a Tekton Pipeline worked like a charm...

Building and pushing container images on Codeberg CI

As part of moving my services to EU-based infrastructure, I've been migrating away from GitHub to @Codeberg One of the things I needed was a CI pipeline to build a container image and push it to the Codeberg container registry for my @catfires bot . It took a few tries to get right, so here's what works for me.

Building and pushing container images on Codeberg CI

Logo: Codeberg e.V. โ€” CC BY-SA 4.0 As part of moving my services to EU-based infrastructure, Iโ€™ve been migrating away from GitHub to Codeberg, a non-profit code hosting platform based in Germany. One of the things I needed was a CI pipeline to build a container image and push it to the Codeberg container registry for my wildfires project (which also posts to @[email protected]). It took a few tries to get right, so hereโ€™s what works for me.

I figured out multiarch container images hosted on forgejo.

In this case I cross compile all golang binaries in one job and then use buildah --arch to build container images for different architectures.
This saves a lot of time compared to building the go binaries inside the architecture emulation.

With both images in the manifest, docker/podman pull/run works on amd64 and arm64 with the same image name.

Just connected a self hosted ci runner to my #codeberg account. Love my CI building and publishing new container images right into codeberg's package/image repository when i push to a repo.

This post brought to you by trying to build #Angular DevTools inside a #buildah environment and isn't nearly as absurd as you think it is.

And another small improvement: Cut down the bookwyrm aarch64 image build time from 17 minutes to 6 by installing libsass from apt and instructing the libsass wheel build to use that instead of building the lib.

New blog post: https://blog.mei-home.net/posts/improving-container-image-build-perf-with-buildah/

I describe how I reduced runtimes of my container image builds, using buildah and not doing emulation via BuildKit anymore.

Improving Multi-Arch Image Build Performance by not Emulating

I've recently improved my container image build performance by not emulating anymore

So in short: Running buildah builds for amd64+arm64 on a CephFS RBD backed by an SSD pool sequentially with the OverlayFS driver is faster than running the same build, on CephFS backed by HDDs with the VFS driver, with the arm64 and amd64 builds running in parallel.
