Preventing Kubernetes from Pulling the Pause Image from the Internet

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.

Ooft. If it helps, this is the PEM I'm getting. LetEncrypt signed.

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.

I'm running k3s at home on single node with local storage. Few blogs, forum, minIO.
Very easy, reliable.
Without k3s I would have use Docker, but k3s really adds important features: easier to manage network, more declarative configuration, bundled Traefik...
So, I'm convinced that quite a few people can happily and efficiently use k8s.
In the past I used other k8s distro (Harvester) which was much more complicated to use and fragile to maintain.

Check out Talos Linux if you haven't already, it's pretty cool (if you want k8s).

I use k3s for my home and for dev envs I think it's completely fine especially when it comes to deployment documentation.
I am way more comfortable managing a system that is k3s rather than something that is still using tmux that gets wiped every reboot.
Well... it's what I would have said until bitnami pulled the rug and pretty much ruined the entire ecosystem as now you don't have a way to pull something that you know is trusted with similar configuration and all from a single repository which makes deployments a pain in the ass.
However, on the plus side I've just been creating my own every time I need one with the help of claude using bitnami as reference and honestly it doesn't take that much more time and keeping them up to date is relatively easy as well with ci automations.

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).

Pretty much all enterprises are using their own ECR/GCR/ACR.
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.
