Kubernetes Cluster Setup with Ansible Inventory for Kubespray Project

This directory contains an Ansible inventory file for setting up a Kubernetes cluster using the kubespray project.

Setup steps

1. Clone the Kubespray repository and checkout a specific release:

    git clone https://github.com/kubernetes-sigs/kubespray --branch <version>
   

2. Install Ansible:

    VENVDIR=kubespray-venv
    KUBESPRAYDIR=kubespray
    python3 -m venv $VENVDIR
    source $VENVDIR/bin/activate
    cd $KUBESPRAYDIR
    pip install -U -r requirements.txt

Steps to Rebuild Inventory

1. Navigate to the cloned kubespray directory in this project:

    # Copy ``inventory/sample`` as ``inventory/mycluster``
    cp -rfp inventory/sample inventory/mycluster
    
    # Update Ansible inventory file with inventory builder
    declare -a IPS=(10.10.1.3 10.10.1.4 10.10.1.5)
    CONFIG_FILE=inventory/mycluster/hosts.yaml python3 contrib/inventory_builder/inventory.py ${IPS[@]}

NOTE:

• the IPs should match the configuration from Ansible config and Terrafrom config
• kubespray inventory will rename the hostnames of your machines so match it from generated "node"

2. Modify the cluster variables according to your cluster requirements.

Initializing the Cluster

1. Run the following command from the root directory of this project:

   ansible-playbook -i ../proxmox cluster.yaml

For more detailed information, please refer to the Kubespray documentation and Ansible documentation for additional customization options.
