Build an OCI (Open Container Initiative) image.

By default, the image is generated in a directory called

rootfs-oci:

$ cd output/images

$ ls rootfs-oci/

blobs index.json oci-layout

You can push the image to a registry. Example using skopeo:
|

$ skopeo copy --dest-creds <user>:<pass> \
|
oci:rootfs-oci:<tag> docker://<user>/<image>[:tag]
|
|
And pull/run it with docker:

$ docker run -it <user>/<image>[:tag]
