umoci new - Create a blank tag in an OCI image
umoci new --image=image[:tag]
Create a blank tag in an OCI image. The created image's configuration and manifest are all set to umoci-defined default values, with no filesystem layer blobs added to the image.
Once a new image is created with umoci-new(1) you can directly use the image with umoci-unpack(1), umoci-repack(1), and umoci-config(1) to modify the new tagged image as you see fit. This allows you to create entirely new images from scratch, without needing a base image to start with.
The global options are defined in umoci(1).
--image=image[:tag]
The destination of the blank tag in the OCI image. image must be a
path to
a valid OCI image, and tag must be a valid tag name. If a tag already
exists with the name tag it will be overwritten. If tag is not
provided
it defaults to "latest".
The following creates a brand new OCI image layout and then creates a blank tag for further manipulation with umoci-repack(1) and umoci-config(1).
% umoci init --layout image % umoci new --image image:tag
