- Add 2024.1 overrides to those charts where there are overrides for previous releases. - Update some jobs to use 2024.1 overrides. - Update default images in grafana, postgresql, nagios, ceph-rgw, ceph-provisioners, kubernetes-node-problem-detector - Install tzdata package on K8s nodes. This is necessary for kubernetes-node-problem-detector chart which mounts /etc/localtime from hosts. Change-Id: I343995c422b8d35fa902d22abf8fdd4d0f6f7334 |

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.
