Sooo, I spent most of my day —unsuccessfully— diagnosing why #Kaniko fails to pull images from our internal #GitLab dependency proxy.

That was fun.

Short guide about how to build Docker images with kaniko on Kubernetes-based GitLab Runners

I worked around the problem with the #Github Actions Runner by trying out #Tekton instead and it worked! At first at least. The image was built and pushed, but I then discovered that #Kaniko had used #Docker layers on top of the existing #OCI Layers of the Image. That made for an invalid image, at least for my use-case…

@dragnucs Difficult and embarassing topic.
I wrote prototypes for Terraform Providers for #podman, #buildah and #kaniko IIRC.
ALL of them are horrible at caching layers - let alone remote exec.
The only descend approach which supports caching seems to be #buildx + #buildkit. And yes, I have a prototype implementation for that as well.
We are still not testing this though, since hosting a Buildkit Remote Builder on GKE is a nightmare.
Let alone error handling in both buildx and buildkit is BAD.
