Microk8s requirements 28/stable MicroK8s is the simplest production-grade conformant K8s. If there are more than three nodes, then a spare one is automatically promoted if a data store node goes offline, creating a zero-ops resilient HA Kubernetes which can lose nodes and heal itself. Tweak this to your own needs and requirements. CPU: A 2-core processor is the minimum recommended for each node. - canonical/microk8s. separate VLANs for control plane and data-plane traffic). They’ll help you achieve an end result but may require you to understand and adapt the steps to fit your specific requirements. microk8s is running high-availability: no datastore master nodes: 127. However, for a more stable and efficient operation, especially for larger workloads, at least 4 CPU cores per node is recommended. In closing, though K3s and MicroK8s both flaunt distinct capabilities within the sphere of lightweight Kubernetes variants, the ultimate selection hinges on the user's preferences and requirements.

Maybe microk8s changed the calico config you get by default when you pull up a cluster and that made it define a different interface? Looking here 1 , they have different install options and one of them is the VXLAN so that's definitely point to the direction that the default Calico config of microk8s was changed somewhere along the line and the inspect script was MicroK8s is the simplest production-grade upstream K8s. Cilium currently defaults to proactively deleting other CNI plugins and their config, and must be configured with cni.
