Buildah — A command line tool that facilitates building OCI container images.
buildah [Options] COMMAND [ARG...]
The Buildah package provides a command line tool which can be used to:
* Create a working container, either from scratch or using an image as a starting point. * Mount a working container's root filesystem for manipulation. * Unmount a working container's root filesystem. * Use the updated contents of a container's root filesystem as a filesystem layer to create a new image. * Delete a working container or an image.
This tool needs to be run as the root user.
- Print debugging information
- --help, -h
- Show help
- --registries-conf path
- Pathname of the configuration file which specifies which registries should be consulted when completing image names which do not include a registry or domain portion. It is not recommended that this option be used, as the default behavior of using the system-wide configuration (/etc/containers/registries.conf) is most often preferred.
- --registries-conf-dir path
- Pathname of the directory which contains configuration snippets which specify registries which should be consulted when completing image names which do not include a registry or domain portion. It is not recommended that this option be used, as the default behavior of using the system-wide configuration (/etc/containers/registries.d) is most often preferred.
- --root value
- Storage root dir (default: "/var/lib/containers/storage") Default root dir is configured in /etc/containers/storage.conf
- --runroot value
- Storage state dir (default: "/var/run/containers/storage") Default state dir is configured in /etc/containers/storage.conf
- --storage-driver value
- Storage driver. Default Storage driver is configured in /etc/containers/storage.conf. Overriding this option, will drop the storage-opt definitions was well from the storage.conf file. User must specify additional options via the
- --storage-opt value
- Storage driver option, Default Storage driver options are configured in /etc/containers/storage.conf
- --version, -v
- Print the version

|storage.conf(5)||Syntax of Container Storage configuration file|
storage.conf is the storage configuration file for all tools using containers/storage The storage configuration file specifies all of the available container storage options for tools using shared container storage.
/usr/share/containers/mounts.conf and optionally
The mounts.conf files specify volume mount directories that are automatically mounted inside containers when executing the `buildah run` or `buildah build-using-dockerfile` commands. Container process can then use this content. The volume mount content does not get committed to the final image. Usually these directories are used for passing secrets or credentials required by the package software to access remote package repositories. For example, a mounts.conf with the line "`/usr/share/rhel/secrets:/run/secrets`", the content of `/usr/share/rhel/secrets` directory is mounted on `/run/secrets` inside the container. This mountpoint allows Red Hat Enterprise Linux subscriptions from the host to be used within the container. Note this is not a volume mount. The content of the volumes is copied into container storage, not bind mounted directly from the host.
registries.conf is the configuration file which specifies which registries should be consulted when completing image names which do not include a registry or domain portion.
