  • Yeah that pause image was really annoying when I was hosting a k8s cluster on Hetzner, since the `registry.k8s.io` -registry was blocking some Hetzner IPs, since its hosted on Google.

  • Nice to know, though I wonder how many companies are really using all private images? I've certainly had a client running their own Harbor instance, but almost all others pulled from Docker Hub or Github (ghcr.io).

  • I believe this has been patched time and time again in on-premises variants like OpenShift. Curious to check if it’s there in small variants like microk8s, k3s, etc., as I’m considering moving a few offline services to Talos.

  • I've used k8s before a lot and at several companies. I am convinced that 99.9% of the people who use it should not be. But it's more fun than deploying VM images at least.

  • O/T, but I'm getting a cert error on this page - wonder if it's just me or if this site is just serving a weird cert. Looks like it's signed by some Fortinet appliance - maybe I'm getting MITMed? Would be kind of exciting/frightening if so.

    EDIT: I loaded the page from a cloud box, and wow, I'm getting MITMed! Seems to only be for this site, wonder if it's some kind of sensitivity to the .family TLD.

  • I went down this rabbit hole not so long ago too.

    There was a discussion open on containerd's GitHub on removing the dependency on the pause image but it has been closed as won't fix: https://github.com/containerd/containerd/issues/10505

    Also, if you are using kubeadm to create your cluster, beware that kubeadm may be pre-pulling a different pause image if it does not match your containerd configuration: https://github.com/kubernetes/kubeadm/issues/2020

  • Just to save someone 5 minutes of research, if you are using the EKS AMIs based on AL2023 or Bottlerocket, this is already done for you by pointing to an image on ECR. At least on Bottlerocket, I haven't checked AL2023, the image is baked into the AMI so you don't even need to pull it from ECR.

  • It bugs me that this implementation detail of containerd has leaked to such an extent. This should be part of the containerd distribution, and should not be pulled at runtime.

    Instead of just swapping out the registry, try baking it into your machine image.
