4.11. Building disk images of image-mode RHEL with advanced partitioning

Procedure

1. Create a config.toml file to configure custom mount options, for example:

   [[customizations.filesystem]]
   mountpoint = "/"
   minsize = "10 GiB"
   
   [[customizations.filesystem]]
   mountpoint = "/var/data"
   minsize = "20 GiB"

2. Run bootc-image-builder, passing the config.toml as an argument.

   참고

   If you do not have the container storage mount, your image must be public.

   The following is an example of creating a public image:

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