2.5. Using bootc-image-builder to build disk images based on a container

Procedure

1. Login to authenticate to registry.redhat.io:

   $ sudo podman login registry.redhat.io

2. Install the bootc-image-builder tool:

   $ sudo podman pull registry.redhat.io/rhel10/bootc-image-builder

Procedure

1. Optional: Create a config.toml to configure user access, for example:

   [[customizations.user]]
   name = "user"
   password = "pass"
   key = "ssh-rsa AAA ... user@email.com"
   groups = ["wheel"]

2. Manually pull the image:

   $ sudo podman pull quay.io/quay.io/<_namespace_>/<_image_>:<_tag_>

3. Create the output directory for the image that you are building:

   $ mkdir output

4. Run bootc-image-builder to create the image. If you do not want to add any configuration, omit the -v $(pwd)/config.toml:/config.toml argument.

   $ sudo podman run \
       --rm \
       -it \
       --privileged \
       --pull=newer \
       --security-opt label=type:unconfined_t \
       -v /var/lib/containers/storage:/var/lib/containers/storage \
       -v $(pwd)/config.toml:/config.toml \
       -v $(pwd)/output:/output \
       registry.redhat.io/rhel9/bootc-image-builder:latest \
       --type iso \
       --config /config.toml \
     quay.io/<namespace>/<image>:<tag>

   You can find the .iso image in the output folder.

   [[customizations.user]]
   name = "user"
   password = "pass"
   key = "ssh-rsa AAA ... user@email.com"
   groups = ["wheel"]

2. Manually pull the image:

   $ sudo podman pull quay.io/<namespace>/<image>:_<tag>_

3. Create the output directory for the image that you are building:

   $ mkdir output

4. Run bootc-image-builder to create the image. If you do not want to add any configuration, omit the -v $(pwd)/config.toml:/config.toml argument.

   $ sudo podman run \
       --rm \
       -it \
       --privileged \
       --pull=newer \
       --security-opt label=type:unconfined_t \
       -v /var/lib/containers/storage:/var/lib/containers/storage \
       -v $(pwd)/config.toml:/config.toml \
       -v $(pwd)/output:/output \
       registry.redhat.io/rhel10/bootc-image-builder:latest \
       --type iso \
       --config /config.toml \
     quay.io/<namespace>/<image>:<tag>

   You can find the .iso image in the output folder.
