Cilium CNI & SKS

The Cilium CNI is now even easier to use with SKS. While SKS has had previous support for other CNIs than our default Calico setup, we now enabled a simple switch to specify Cilium instead. While initiating your cluster you can specify Cilium as CNI plugin using the --cni flag:

exo compute sks create my-test-cluster \
    --zone de-fra-1 \
    --cni cilium \
    --service-level pro \
    --nodepool-name my-test-nodepool \
    --nodepool-size 3 \
    --nodepool-security-group sks-security-group

Cilium is an open source software providing and securing network connectivity between application workloads like containers or processes. The software is integrated into orchestration frameworks like Kubernetes.

A Linux eBPF Kernel is at the foundation of Cilium. The kernel supports dynamic insertion of eBPF bytecode, like security, visibility, and networking control logic. eBPF is used to provide high-performance networking, multi-cluster capabilities, extensive network security capabilities and more.
