4.5. Creating VMDK images by using bootc-image-builder

Procedure

1. Create a Containerfile with the following content:

   FROM registry.redhat.io/rhel10/rhel-bootc:latest
   RUN dnf -y install cloud-init open-vm-tools && \
   ln -s ../cloud-init.target /usr/lib/systemd/system/default.target.wants && \
   rm -rf /var/{cache,log} /var/lib/{dnf,rhsm} && \
   systemctl enable vmtoolsd.service

2. Build the bootc image:

   # podman build . -t localhost/rhel-bootc-vmdk

3. Create a VMDK file from the previously created bootc image. The image must be accessible from a registry, such as registry.redhat.io/rhel10/bootc-image-builder:latest.

   # podman run \
   --rm \
   --privileged \
   -v /var/lib/containers/storage:/var/lib/containers/storage \
   -v ./output:/output \
   --security-opt label=type:unconfined_t \
   --pull newer \
   registry.redhat.io/rhel10/bootc-image-builder:latest \
   --type vmdk \
   --config /config.toml \
   localhost/rhel-bootc-vmdk:latest

   A VMDK disk file for the bootc image is stored in the output/vmdk directory.
