Usage

Packer configuration can be done via .packerconfig config file or environment variables (e.g. PACKER_LOG=1 for verbose logging). Environment variables are preferred when using docker.

QEMU builder

# Note: The GID of the group 'kvm' in the container must match the host's. If not, use --privileged instead of --device. See: https://stackoverflow.com/questions/48422001/how-to-launch-qemu-kvm-from-inside-a-docker-container
docker run --rm -it \
    --device /dev/kvm \
    -v $(pwd):/src \
    -w /src \
    theohbrothers/docker-packer:1.7.7-sops-qemu-ubuntu-20.04 packer build template.json

See examples:

• Ubuntu 20.04 VM .qcow2 image

Virtualbox builder

The host may need to have an exact matching virtualbox version, or at least the same virtualbox minor version, if not virtualbox may not be able to start VMs. To verify virtualbox can start VMs, run the following, ensuring there is no error message:

docker run --rm -it \
    --device /dev/vboxdrv \
    theohbrothers/docker-packer:1.7.7-sops-virtualbox-7.0.8-ubuntu-20.04 vboxmanage --version

If all is well, to build a VM image:

docker run --rm -it \
    --device /dev/vboxdrv \
    -v $(pwd):/src \
    -w /src \
    theohbrothers/docker-packer:1.7.7-sops-virtualbox-7.0.8-ubuntu-20.04 packer build template.json

See examples:

• Ubuntu 20.04 VM .ova

Other builder(s)

docker run --rm -it \
    -v $(pwd):/src \
    -w /src \
    theohbrothers/docker-packer:1.7.7-sops-ubuntu-20.04 packer build template.json
