Hi there,

I don’t think there’s an official guide on changing the CNI in DOKS. Since it’s a managed service, swapping out the default Cilium for something like Calico might not be supported and could lead to issues. It’s probably best to stick with the default Cilium CNI unless you have a strong reason to switch.

If you really need the flexibility of choosing your own CNI, a self-hosted Kubernetes cluster might be the way to go. This way, you have full control over the networking stack and can use Calico or any other CNI of your choice:

For clarification or to see if there’s any workaround, I’d recommend reaching out to DigitalOcean support:
