Does it support NetworkPolicy? BGP? eBPF? Encryption? Observability? Those are useful questions, but I think they miss the first one: What networking problem does this cluster actually need the CNI to solve? A three-node K3s cluster and a large multi-tenant Kubernetes platform do not need the same network architecture. Start with what the CNI does A pod needs an IP address and it needs to communicate with other pods.https://eljirari.me/posts/containers-thebackstory/Wed, 30 Aug 2023 22:53:30 +0100https://eljirari.me/posts/containers-thebackstory/Back in my student days, I first bumped into Docker. It was all the rage then, and honestly, it blew my mind. The idea that you could take a piece of code, make it work anywhere in its own little space, separate from the computer’s main system – that was pretty cool. Later on, I found out Docker wasn’t the first to come up with this container and isolation stuff. In this blog post, I want to take you on a little trip back in time to check out who started it all.
