Proxmox : Terraform : K3S

Assumptions

You have a Proxmox Server/Cluster capable of running 4+ Linux VM's
You have an Internet Connection
You're comfortable with the CLI in Linux
Understand containerization concepts
Watch lots of home lab YouTube content :)

Order of operations

Create Proxmox User w/ API Token
Create VM template via 'build_cloud_image_vm_template.sh' (must be done on proxmox host)
- edit script to fit your proxmox environment
  - VMID
  - TMPL_NAME
  - TMPL_DESCRIPTION
  - PVE_DISK
  - DISK_SZ
  - PVE_NODE
- assign ssh public key in build script for cloud init drive
- Currently designed to create Ubuntu 23.04 Cloud Image VM/Template

ssh root@pve-6

apt update -y && apt install libguestfs-tools -y

cd k3s_deployment/modules/pm_vm_template

Add SSH public keys to the id_sshkeys.pub file as this file is used to seed the cloud image drive.
Change variables in build_cloud_image_vm_template.sh to ensure you're pointing to the right PVE SERVER, PVE DISK, etc.

bash ./build_vm_template.sh

VIRTUAL MACHINE TEMPLATE: [9900 - ubun2204-k3s-tmpl-01]

Provision 5 - 6 VM's from VM template using Terraform
- 3 Server Nodes and 2 - 3 Worker Nodes
  - Server Nodes: 2 CPU / 4 GB RAM (2 GB min)
  - Worker Nodes: 2 CPU / 8 GB RAM
- edit terraform.tfvars and main.tf as required
- assign static ip scheme to support K3S deployment

terraform init

terraform apply -auto-approve

K3S SRVR::VIRTUAL MACHINES: [7701/2/3 - k3s-srvr-nodes-(1-3)] FROM THE TEMPLATE ON PVE-6: [9900 - ubun2204-k3s-tmpl-01]

K3S WRKR::VIRTUAL MACHINES: [7201/2/3 - k3s-wrkr-nodes-(1-3)] FROM THE TEMPLATE ON PVE-5: [9200 - ubun2204-k3s-tmpl-02]

Execute K3S deployment script

./k3s.sh

ENJOY and begin to containerize all the things!
