Openstack and Rook/Ceph Cluster.

This repository contains scripts to automate the creation of a 4-node Kubernetes cluster on Proxmox VE. It is specifically designed for running Rook/Ceph as the storage backend and supports multi-bridge network setups (e.g., vmbr1199 and vmbr2199).

🧩 Features

• Automated VM creation and configuration via Proxmox CLI
• Support for multi-network interfaces (Kolla-Ansible compatibility)
• Prepares nodes for Kubespray-based Kubernetes installation
• Ready for Rook-Ceph deployment
• Generates globals.yml and passwords.yml for Kolla-Ansible
• Automatically integrates Ceph credentials and configuration
• Supports VM template creation from Ubuntu 24.04 Cloud image

📦 Requirements

• A working Proxmox VE hypervisor
• Internet access on the host machine to download images and tools
• Proxmox CLI access (run as root)
• cloud-init installed on the guest image
• VM Template ID to clone from

🚀 Usage

1. Clone this repository

git clone https://github.com/senolcolak/proxmox-k8s4rook.git
cd proxmox-k8s4rook

2. Create a cloud-init ready VM template (only once)

⚙️ This will create a VM template (ID 4444 by default) based on Ubuntu 24.04 Cloud image.

3. Deploy 4-node cluster from the template

./install-k8s.sh <TEMPLATE_ID> <START_VM_ID> <IP_RANGE>

Example:

./install-k8s.sh 4444 5001 10.1.99.121-10.1.99.124

The script will automatically create VMs with:

• 2 interfaces: vmbr99 (default) and vmbr2199
• Cloud-init config for each node
• SSH key injection (you can modify this)
• Hostname and static IP configuration

🔐 Ceph / Rook Integration

If you have an existing Rook-Ceph cluster:

• The script will ask for the IP/DNS of the Rook-Ceph toolbox host
• It will fetch ceph.conf and relevant keyrings
• These will be placed under /etc/kolla/config/cinder, glance, swift, etc.
• You can modify the behavior in the script to suit your environment

🛠️ Output Files

• globals.yml: Pre-generated for Kolla-Ansible customization
• passwords.yml: Auto-generated secure password file
• VM Configurations stored in Proxmox VMDB
• Ceph credentials copied under correct config directories

⚠️ Notes

• Tested with Ubuntu 24.04 and Proxmox 7.x
• Ensure vmbr1199 and vmbr2199 are correctly configured on your Proxmox host
• Make sure cloud-init and SSH keys are functional in the template
• Script assumes 4-node setup, but can be modified easily for more
