This role is used to deploy test environment which includes
|
|
- install necessary prerequisites including Helm
|
|
- deploy Containerd and a container runtime for Kubernetes
|
|
- deploy Kubernetes using Kubeadm with a single control plane node
|
|
- install Calico as a Kubernetes networking
|
|
- establish tunnel between primary node and K8s control plane ndoe
|
|
|
|
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.
|
