#### **--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.
