Proxmox Terraform Ansible Kubernetes

Setting up a Kubernetes cluster in Proxmox using Ansible git clone --recurse-submodules -j8 [email protected]:krisunni/ptak.git Version Check

• Proxmox 8.1.3
• Terraform v1.6.5
• Ansible [core 2.16.1]

1. Scripts to create ubuntu image Download and create Ubuntu VM template image.sh

2. Create hosts using Terraform on Proxmox.

   • As of writing, Proxmox 8.1.3 API update is still not fixed in the Telmate/terraform-provider-proxmox #869.
   • I am using a forked provider that is added as a submodule.
   • Build Proxmox Terraform lib as workaround
     • Version Check
       • GNU Make 3.81
       • go version go1.21.1
     • Run this command to build the file. export VERSION=2.9.14 && cd ./terraform/.terraform/providers/terraform.local/frostyfab && make

3. Update Host IP and Gateway for your network in var

    variable "ip" {
    default = "192.168.0"
    }
    variable "gateway" {
    default = "192.168.0.1"
    }

1. Apply Terrafrom to create hosts

   cd terraform
   terraform init
   terraform apply
   

2. Configure host using Ansible
   • Modify Host ip in
   • Check if Hosts are ready. Note ANSIBLE_HOST_KEY_CHECKING disables host key against the known_hosts file. This is optoinal if known_hosts has all the hosts.
     • ANSIBLE_HOST_KEY_CHECKING=False ansible -i hosts.txt all -u ubuntu -m ping
       • Example Output

5. Init Kubernets Cluster in the main host ansible-playbook -i hosts.txt init-cluster.yml
6. Get Join command for Agents from Main ansible-playbook -i hosts.txt join-command.yml
7. Join Agents to Main ansible-playbook -i hosts.txt join-agents.yml
