- install Calico as a Kubernetes networking
- establish tunnel between primary node and K8s control plane ndoe
The role works both for singlenode and multinode inventories and
assumes the inventory has the node called `primary` and the group called `nodes`.
The role works both for single-node and multi-node inventories. The role
totally relies on inventory groups. The `primary` and `k8s_control_plane`
groups must include only one node and this can be the same node for these two
groups.
The `primary` group is where we install `kubectl` and `helm` CLI tools.
You can consider this group as a deployer's machine.
The `k8s_control_plane` is where we deploy the K8s control plane.
The `k8s_cluster` group must include all the K8s nodes including control plane
and worker nodes.
In case of running tests on a single-node environment the group `k8s_nodes`
must be empty. This means the K8s cluster will consist of a single control plane
node where all the workloads will be running.
