Build the operating system disk image

Use bootc-image-builder to generate an ISO disk image from your operating system image.

About this task

Build the operating system disk image that contains the file system for your devices. Complete the following steps:

Procedure

  1. Create a directory called output by running the following command: 
    mkdir -p output
  2. Use bootc-image-builder to generate an operating system disk image of type iso from your operating system image. Run the following command: 
    sudo podman run --rm -it --privileged --pull=newer \
    --security-opt label=type:unconfined_t \
    -v "${PWD}/output":/output \
    -v /var/lib/containers/storage:/var/lib/containers/storage \
    registry.redhat.io/rhel9/bootc-image-builder:latest \
    --type iso \
    ${OCI_IMAGE_REPO}:${OCI_IMAGE_TAG}

    When the bootc-image-builder completes, you can find the ISO disk image at the ${PWD}/output/bootiso/install.iso path.
