Kubernetes Cluster API Provider Proxmox (CAPPVE)

---

What is Cluster API Provider Proxmox

Cluster API brings declarative, Kubernetes-style APIs to cluster creation, configuration and management.

Proxmox is an open source hypervisor for launching QEMU VMs and LXC containers

The Cluster API Provider Proxmox allows a Proxmox host / cluster to respond to the infrastructure requests from Cluster API configurations.

Getting Started

Before installation, be sure to check the Requirements section first, to ensure your Proxmox environment is ready

Installation

Add the following provider configuration to ~/.cluster-api/clusterctl.yaml

providers:
  - name: "proxmox"
    url: "https://github.com/launchboxio/cluster-api-provider-proxmox/releases/latest/infrastructure-components.yaml"
    type: "InfrastructureProvider"

We can then install the provider alongside ClusterAPI

clusterctl init --infrastructure proxmox

Requirements

• NFS storage volume for snippets (https://github.com/launchboxio/cluster-api-provider-proxmox/issues/8)
• Proxmox deployed as a cluster (https://github.com/launchboxio/cluster-api-provider-proxmox/issues/9)

Credentials

Proxmox API

export PM_API_URL=https://proxmox:8006/api2/json
export PM_API_TOKEN_ID=user@pve!cluster-api
export PM_API_TOKEN_SECRET="xxxxxxxxxxx-xxxxx-xxxx-xxxx"
export NAMESPACE="my-cluster"

kubectl create secret generic proxmox \
  --from-literal=api_url="${PM_API_URL}" \
  --from-literal=token_id="${PM_API_TOKEN_ID}" \
  --from-literal=token_secret="${PM_API_TOKEN_SECRET}" \
  -n "${NAMESPACE}"

Storage

export HOST="0.0.0.0:22"
export USER="user_id"
export PASS="password"
export NAMESPACE="my-cluster"

kubectl create secret generic storage-access \
  --from-literal=host="${HOST}" \
  --from-literal=user="${USER}" \
  --from-literal=password="${PASSWORD}" \
  -n "${NAMESPACE}"

Template

This provider requires that a base cloud init template be created, which it can use to start and configure Kubernetes nodes. At the moment, only Ubuntu 22.04 has been tested, but other Ubuntu versions may work

SSH to one of the Proxmox nodes, and perform the following

export TEMPLATE_ID=XXXX  
export STORAGE="storage"
export DISK_SIZE="32G"

wget  https://cloud-images.ubuntu.com/releases/focal/release/ubuntu-20.04-server-cloudimg-amd64.img
qm create "${TEMPLATE_ID}" --memory 2048 --net0 virtio,bridge=vmbr0 # Change other configurations if needed
qm importdisk "${TEMPLATE_ID}" ubuntu-20.04-server-cloudimg-amd64.img "${STORAGE}"
qm set "${TEMPLATE_ID}" --scsihw virtio-scsi-pci --scsi0 storage:vm-9001-disk-0
qm set "${TEMPLATE_ID}" --serial0 socket --vga --serial0
qm set "${TEMPLATE_ID}" --ide2 storage:cloudinit
qm set "${TEMPLATE_ID}" --boot c --bootdisk scsi0
qm resize "${TEMPLATE_ID}" scsi0 "${DISK_SIZE}"

This template can then be used as a base for launching the Kubernetes nodes
