It seems at one time the older docs mentioned calico based on this https://github.com/gravitational/gravity/pull/14. The newer 6.x doesn’t seem to. Can I run calico on a gravity cluster? What should my cluster YAML file look like to build a k8s cluster that has calico on it? I want to leverage network policy and I prefer calico for features and because it’s the reference implementation that the k8s folks use to do design k8s network policy, at least not long ago it was.
