Deciding on a CNI
We support two different CNIs, that being Flannel and Cilium. Flannel is known for it's simplicity and Cilium for it's advanced even service mesh like features.
Flannel focuses on the integral part that is the network connection itself. It does not provide any NetworkPolicies or traffic encryption, but it is rock solid when it comes to inter pod communication. That makes it a good choice if you want to chain CNIs and/or add a Service-Mesh on top of it.
If you are interested in more advanced CNI features like NetworkPolicies, traffic encryption, mutal TLS and network Observability, Cilium is the right choice for you. It can provide many features that would otherwise neccesstiate a full blown ServiceMesh like Istio. You can find out more on their website: https://cilium.io.
