SYNOPSIS

container build ['OPTIONS']

DESCRIPTION

The container build command builds a container based on a script.

The following build scripts are available:

--bind-ro='DIRECTORY:DIRECTORY[:OPTIONS][;DIRECTORY:DIRECTORY[:OPTIONS]]':: Specify container read-only bind mounts, see systemd-nspawn(1) --bind-ro option.
--cnt-overlay='DIRECTORY_LOWER:DIRECTORY_UPPER:DIRECTORY_WORK:DIRECTORY_MERGED[;DIRECTORY_UPPER:DIRECTORY_LOWER:DIRECTORY_WORK:DIRECTORY_MERGED]':: Specify container overlay mounts, see Documentation/filesystems/overlayfs.txt.
