Another distro goes to @cilium.io 🐝
First it was GKE. Then EKS. Then AKS. Now Canonical Kubernetes ☸️ At this point, it’s getting hard to find a major Kubernetes distro that doesn’t ship with Cilium.

Kubernetes "native" sidecars are slated for GA in 1.33, so it's a good time to brush up on how (and why) to use them.
Solve this practical challenge by reworking a flawed pod, making it use a native sidecar:
