I do not recommend this project being used for ones own infrastructure, as this project is heavily attuned to my specific host/network setup

This Ansible project automates the setup of a K3s Kubernetes cluster on Proxmox VE. It also includes playbooks for configuring Docker hosts, load balancers, and other services.

Repository Structure

The repository is organized into the following main directories:

• playbooks/: Contains the main Ansible playbooks for different setup scenarios.
• roles/: Contains the Ansible roles that are used by the playbooks.
• vars/: Contains variable files, including group-specific variables.

Playbooks

The following playbooks are available:

• proxmox.yml: Provisions VMs and containers on Proxmox VE.
• k3s-servers.yml: Sets up the K3s master nodes.
• k3s-agents.yml: Sets up the K3s agent nodes.
• k3s-loadbalancer.yml: Configures a load balancer for the K3s cluster.
• k3s-storage.yml: Configures storage for the K3s cluster.
• docker.yml: Sets up Docker hosts and their load balancer.
• docker-host.yml: Configures the docker hosts.
• docker-lb.yml: Configures a load balancer for Docker services.
• kubernetes_setup.yml: A meta-playbook for setting up the entire Kubernetes cluster.

Roles

The following roles are defined:

• common: Common configuration tasks for all nodes.
• proxmox: Manages Proxmox VE, including VM and container creation.
• k3s_server: Installs and configures K3s master nodes.
• k3s_agent: Installs and configures K3s agent nodes.
• k3s_loadbalancer: Configures an Nginx-based load balancer for the K3s cluster.
• k3s_storage: Configures storage solutions for Kubernetes.
• docker_host: Installs and configures Docker.
• kubernetes_argocd: Deploys Argo CD to the Kubernetes cluster.
• node_exporter: Installs the Prometheus Node Exporter for monitoring.
• reverse_proxy: Configures a Caddy-based reverse proxy.

Usage

1. Install dependencies:

   pip install -r requirements.txt
   ansible-galaxy install -r requirements.yml
   

2. Configure variables:

   • Create an inventory file (e.g., vars/k3s.ini).
   • Adjust variables in vars/group_vars/ to match your environment.

3. Run playbooks:

   # To provision VMs on Proxmox
   ansible-playbook -i vars/proxmox.ini playbooks/proxmox.yml
   
   # To set up the K3s cluster
   ansible-playbook -i vars/k3s.ini playbooks/kubernetes_setup.yml
