Scripts and automation to deploy kubernetes on photon OS

Packer Build for Photon 5 Kubernetes Template VM

This repository contains files for automated build, configuration and deployment of a VMware Photon OS v5 image using Hashicorp packer ready to be configured as part of a Kubernetes cluster (k8s) to be deployed to a vSphere environment as virtual machines. The way the scripts are written this should be easily adjustable to alternative virtualization platforms. The components and versions are:

• VMware Photon OS v5.0
• containerd v1.7.19
• runc v1.1.13
• CNI plugins v1.5.1
• nerdctl v1.7.6
• calicoctl v3.28.0
• kubectl v1.30.2
• kubectl-convert v1.30.2
• crictl v1.30.1
• kubeadm v1.30.2
• kubelet v1.30.2

The envisaged usage sequence is:

1. Clone the repository, update config.auto.pkrvars.hcl in the packer folder as appropriate for the target environment
2. Run packer init . and packer build . from the packer folder to create a template VM
3. Once a template has been successfully built, the deploy.ps1 PowerShell script in the powershell folder can be used with PowerCLI to deploy VMs for the cluster
4. From within the deployed cluster VMs, run kubeadm to initialize/build the kubernetes cluster and configure components

Alternatively, a 'bare-bones' VM template can be manually built and the script k8s-setup-manual.sh from the packer\data\scripts folder run inside it to perform (mainly) the same actions as the packer build in case of any issues with packer.

Note that the versions of components used are (at the time of writing) the most recent release versions of the components and will be ahead (considerably in some cases) of the versions obtainable from the Photon OS repositories available through tdnf - this is intentional as one of the goals of this project was to be able to expirement with the 'latest and greatest'.
