Flannel

📄️ Install Calico for policy and flannel (aka Canal) for networking

If you use flannel for networking, you can install Calico network policy to secure cluster communications.

📄️ Migrate a Kubernetes cluster from flannel/Canal to Calico

Preserve your existing VXLAN networking in Calico, but take full advantage of Calico IP address management (IPAM) and advanced network policy features.
