--userns-uid-map=mapping
Directly specifies a UID mapping to be used to set ownership, at the
filesystem level, on the working container's contents.
Commands run when handling RUN instructions default to being run in
their own user namespaces, configured using the UID and GID maps.
Entries in this map take the form of one or more triples of a starting in-container UID, a corresponding starting host-level UID, and the number of consecutive IDs which the map entry represents.
This option overrides the remap-uids setting in the options section of /etc/containers/storage.conf.
If this option is not specified, but a global --userns-uid-map setting is supplied, settings from the global option is used.
If none of --userns-uid-map-user, --userns-gid-map-group, or --userns-uid-map are specified, but --userns-gid-map is specified, the UID map is set to use the same numeric values as the GID map.
