Cilium question:

How are `ClusterIP` type services supposed to be routed when Kube-Proxy is replaced?

Like Service Cluster IP Range must be set in the K8s API server configuration, so the IPAM for that is well outside of Cilium's so... is it supposed to be natively routable? Everything says CIDR overlaps are a no-no.

The pod routing table contains nothing about the ClusterIP, though default routing should be okay `traceroute` shows it hitting the node's cluster IP and then just... nothing.

Is eBPF supposed to be doing DNAT?

I don't get it and I'm so close!

Und weiter geht's mit einem Blog zu #OpenCloud per #Helm in #kubernetes: loku.be/250411-opencloud-on-ku - das erste kurze Fazit ist "Erste Tests machen Spaß, die UI ist unglaublich snappy." - das ist, worum es uns (auch) geht: Nur wenn die Software bei der Anwendung auch Spaß macht, werden wir als Alternative zu #Bigtech erfolgreich sein.

TIL that adding CAP_SYS_ADMIN to a #kubernetes pod has different behaviour depending on the backing CRI. With Containerd it does nothing (you need to call it SYS_ADMIN) but on CRI-O it will add ok. Also TIL k8s doesn't validate the capabilities you add to pods!

Philip Laine · Getting Forked by MicrosoftThree years ago, I was part of a team responsible for developing and maintaining Kubernetes clusters for end user customers. A main source for downtime in customer environments occurred when image registries went down. The traditional way to solve this problem is to set up a stateful mirror, however we had to work within customer budget and time constraints which did not allow it. During a Black Friday, we started getting hit with a ton of traffic while GitHub container registries were down. This limited our ability to scale up the cluster as we depended on critical images from that registry. After this incident, I started thinking about a better way to avoid these scalability issues. A solution that did not need a stateful component and required minimal operational oversight. This is where the idea for Spegel came from.

Thinking of refreshing my home server setup. Currently have NixOS on bare metal with a few things running directly there (Nextcloud, NFS server, some lesser things). I’m interested in learning kubernetes some more so I’m considering replacing NixOS with Proxmox then running Kubernetes across some Fedora CoreOS VMs (or some similar container focused OS). Is that a reasonable start? Do folks have any other suggestions for the base setup for #homelab #selfhosted #kubernetes ?
