It is designed for building other VMs inside this VM. + +## Requirements + +- Packer +- QEMU/KVM +- Ubuntu 24.04 Server ISO +- (Optional) Proxmox to run the image + +## Usage + +### Install Prerequisites + +- You can use the provided script to install all necessary tools on your host system or inside an existing VM: + +``` +./scripts/install-prerequisites.sh +``` + +- This sets up tools like Packer, QEMU, and Docker. + +### Build the image + +- Run the following command from the project root to build the image: + +``` +packer build ubuntu-qemu-template.json +``` + +- The resulting .qcow2 image will be saved in the `output/` directory. + +### Post-Processing + +- After the build, the following script generates checksum files with the `scripts/create-checksums.sh` script. It produces .sums files with MD5 and SHA512 checksums. + +### Using the VM + +- Import the image into Proxmox and enable nested virtualization. +- You can then run this image as a VM capable of building other VMs using tools like Packer or Docker-in-Docker. + +## Notes + +- The image uses Ubuntu 24.04 Live Server. +- `scripts/sysprep.sh` prepares the image for reuse (e.g., clears logs, resets machine ID, etc.). +- The template sets defaults like 2 CPUs, 2 cores, 2 GB RAM. +- You can customize variables in the Packer template. + +## File Structure + +- `ubuntu-24.04-server_vm-builder.json` – Main Packer configuration. +- `scripts/install-prerequisites.sh` – Installs dependencies. +- `scripts/sysprep.sh` – Cleans and prepares the image. +- `scripts/create-checksums.sh` – Generates MD5/SHA512 checksums. diff --git a/packer/ubuntu-24.04-server.json b/packer/ubuntu-24.04-server_vm-builder.json index 397bdba..397bdba 100644 --- a/packer/ubuntu-24.04-server.json +++ b/packer/ubuntu-24.04-server_vm-builder.json |
