I’ve deployed multiple K8s clusters with Juju. When deploying 1.19 or 1.20 with Calico, a pod is not able to access an external IP through SNAT. Calico is configured to allow SNAT. When I build a 1.18 K8s cluster, the pods are able to communicate with external devices through SNAT.
Here are some of the errors within the Calico logs:
