Proxmox Auto Installer

Generate custom unattended Proxmox VE installation ISOs using Docker and profile-based configurations.

This tool wraps the official proxmox-auto-install-assistant in a Docker image, allowing you to build automated installer ISOs using separate answer.toml files per profile.

---

📦 Features

• ✅ Supports multiple profile configurations (e.g. pve-1, pve-2)
• ✅ Uses Docker for reproducible, isolated builds
• ✅ Output ISOs labeled with profile names
• ✅ Clean and scriptable interface
• ✅ Works with any Proxmox VE ISO

🛠 Usage

Single Profile

docker run --rm \
  -v $PWD/iso:/iso:ro \
  -v $PWD/secrets:/answers:ro \
  -v $PWD/iso/output:/out \
  proxmox-auto-installer:latest \
    /iso/proxmox-ve_8.4-1.iso \
    pve-1

Multiple Profiles

Loop through profiles:

for profile in pve-1 pve-2; do
  docker run --rm \
    -v $PWD/iso:/iso:ro \
    -v $PWD/secrets:/answers:ro \
    -v $PWD/iso/output:/out \
    proxmox-auto-installer:latest \
    /iso/proxmox-ve_8.4-1.iso \
    $profile
done

---

📁 Output

Output ISOs will be generated in iso/output/:

iso/output/proxmox-ve_8.4-1-auto-pve-1.iso
iso/output/proxmox-ve_8.4-1-auto-pve-2.iso

---

🧪 Troubleshooting

• Ensure the answer.toml file exists in secrets/<profile>/
• Make sure Docker has permission to access the mounted volumes
• Run interactively if you want to debug:

docker run -it --entrypoint /bin/sh proxmox-auto-installer

---

🧹 Cleanup

docker rmi proxmox-auto-installer
rm iso/output/*
