🙌 Credits

Credits goes out to William Lam. The code basis comes from project VMware Event Broker Appliance which William and Michael Gasch are maintaining. I reused the code and stripped it down to the necessary pieces and extended it for my needs.

👓 Overview

This repository contains the necessary code to build a based Kubernetes Appliance.

The Appliance can be quickly deployed on vSphere for testing, development or learning purposes. Perhaps, it serves as the foundation for your project(s) 😉

📋 Requirements

CLI Tools:

• VMware ovftool
• Packer
• jq
• PowerShell - more optional

Network:

• DHCP enabled
• SSH enabled (port 22)
• No network restrictions between the build system (were packer is running on) and the VMware ESXi host
• Packer will create an http server serving http_directory
  • Random port used within the range of 8000 and 9000

vSphere

• ESXi 6.7 or greater
• Enable GuestIPHack on the ESXi host before building the appliance: esxcli system settings advanced set -o /Net/GuestIPHack -i 1

👨‍🍳 Building the Appliance

1. Clone the repository: git clone git@github.com:rguske/kubernetes-appliance.git
2. Change into the directoy: cd kubernetes-appliance
3. Adjust the photon-builder.json file with the appropriate ESXi (build host) data (IP or FQDN, user, password, datastore, network)
4. Execute the build.sh script: ./build.sh

Optional: If you like to change the versions for e.g. Kubernetes or Antrea, modify those in the k8s-app-bom.json

Debugging

The SSH session initiated will be visible in the detail provided when PACKER_LOG=1 environment variable is set within the build.sh script.

Example: PACKER_LOG=1 packer build -var "K8S_APP_VERSION=${K8S_APP_VERSION_FROM_BOM}" -var-file=photon-builder.json -var-file=photon-version.json photon.json ).

Output directoy

The finished ova file will be exported to the output-vmware-iso directory.

💻 zsh installed

I'm a happy user of zsh and oh-my-zsh and therefore, when connecting to the appliance via ssh, you will use a "pimped" shell environment.

Deployment Options Appliance

Join an existing Kubernetes-Appliance

In version v0.3.0, the possibility was added to join an existing Kubernetes-Appliance as an additional node.

📋 Change Log
