kURL: How can I update my pod and service CIDRs

Supporting your customers
1

The default pod and service network conflicts with my existing network and I need to use a different CIDR, how can I do this?

In a kURL embedded cluster, the pod network is managed by weave spec and the service network is managed by kubernetes spec.

Weave Spec: https://kurl.sh/docs/add-ons/weave
Kubernetes Spec: https://kurl.sh/docs/create-installer/add-on-adv-options

This would look something like this when you patch it at runtime:

  apiVersion: "cluster.kurl.sh/v1beta1"
  kind: "Installer"
  metadata:
    name: "patch"
  spec:
    kubernetes:
      serviceCIDR: "10.96.0.0/12"
    weave:
      podCIDR: "10.10.0.0/16"

Note: If you already started the install you need to clean up the VM and start from a fresh OS install for the new CIDRs to take effect, rerunning the installer with the patch will not work.
