Container Network Interfaces (CNIs)

Default

The Default CNI is the default Container Network Interface plugin that is bundled with the Kubernetes distribution you are using. It is often a basic CNI plugin with limited features.

Below is a table of the default CNI plugins for each Kubernetes distribution supported by KSail:

Distribution	CNI
Kind	kindnetd
K3d	flannel

Cilium

Cilium is a powerful CNI plugin that provides advanced networking and security features for Kubernetes clusters. It uses eBPF (Extended Berkeley Packet Filter) technology to provide high-performance networking, load balancing, and security policies.

Using the Cilium CNI will create a Kubernetes cluster with the Cilium CNI plugin pre-installed.

None

The None CNI option means that no Container Network Interface plugin will be installed in your Kubernetes cluster. This is useful if you want to install an unsupported CNI plugin.
