NAME

       umoci raw add-layer - add a layer archive verbatim to an image

SYNOPSIS

       umoci raw add-layer --image=image [--tag=tag] [--no-history] [--history.comment=comment]
       [--history.created_by=created_by] [--history.author=author] [--history-created=date]
       new-layer.tar

DESCRIPTION

       Adds the uncompressed layer archive referenced by new-layer.tar verbatim to the image.
       Note that since this is done verbatim, no changes are made to the layer and thus any
       OCI-specific tar extensions (such as .wh. whiteout files) will be included unmodified. Use
       of this command is therefore only recommended for expert users, and more novice users
       should look at umoci-repack(1) to create their layers.

       At the moment, umoci raw add-layer only supports appending layers to the end of the image
       layer list.

OPTIONS

       The global options are defined in umoci(1).

       --image=image[:tag]
         The source tag to use as the base of the image containing the new layer.
         image must be a path to a valid OCI image and tag must be a valid tag in
         the image. If tag is not provided it defaults to "latest".

       --tag=tag
         The destination tag to use for the newly created image. tag must be a valid
         tag in the image. If tag is not provided it defaults to the tag specified
         in --image (overwriting it).

       --no-history
         Causes no history entry to be added for this operation. This is not
         recommended for use with umoci-raw-add-layer(1), since it results in the
         history not including all of the image layers -- and thus will cause
         confusion with tools that look at image history.

       --history.comment=comment
         Comment for the history entry corresponding to this modification of the image
         If unspecified, umoci(1) will generate an implementation-dependent value.

       --history.created_by=created_by
         CreatedBy entry for the history entry corresponding to this modification of
         the image. If unspecified, umoci(1) will generate an
         implementation-dependent value.

       --history.author=author
         Author value for the history entry corresponding to this modification of the
         image. If unspecified, this value will be the image's author value after
         any modifications were made by this call of umoci-config(1).

       --history-created=date
         Creation date for the history entry corresponding to this modifications of
         the image. This must be an ISO8601 formatted timestamp (see date(1)). If
         unspecified, the current time is used.

EXAMPLE

       The following takes an existing diff directory, creates a new archive from it and then
       inserts it into an existing image. Note that the new archive is not compressed (umoci will
       compress the archive for you).

              % tar cfC diff-layer.tar diff/ .
              % umoci raw add-layer --image oci:foo diff-layer.tar
