NAME
buildah push - Push an image from local storage to elsewhere.
SYNOPSIS
buildah push [options [...]] imageID [destination]
DESCRIPTION
Pushes an image from local storage to a specified destination, decompressing and recompessing layers as needed.
imageID
Image stored in local container/storage
DESTINATION
The DESTINATION is a location to store container images The Image "DESTINATION" uses a "transport":"details" format.
Multiple transports are supported:
atomic:hostname/namespace/stream:tag
An image served by an OpenShift(Atomic) Registry server. The current OpenShift project and OpenShift Registry instance are by default read from $HOME/.kube/config, which is set e.g. using (oc login).
dir:path An existing local directory path storing the manifest, layer tarballs and signatures as individual files. This is a non-standardized format, primarily useful for debugging or noninvasive container inspection.
docker://docker-reference
An image in a registry implementing the "Docker Registry HTTP API V2". By default, uses the authorization state in $HOME/.docker/config.json, which is set e.g. using (docker login).
docker-archive:path[:docker-reference]
An image is stored in the docker save formatted file. docker-reference is only used when creating such a file, and it must not contain a digest.
docker-daemon:docker-reference An image docker-reference stored in the docker daemon internal storage. docker-reference must contain either a tag or a digest. Alternatively, when reading images, the format can also be docker-daemon:algo:digest (an image ID).
oci:path:tag An image tag in a directory compliant with "Open Container Image Layout Specification" at path.
ostree:image[@/absolute/repo/path] An image in local OSTree repository. /absolute/repo/path defaults to /ostree/repo.
OPTIONS
--disable-compression, -D
Don't compress copies of filesystem layers which will be pushed.
--signature-policy
Pathname of a signature policy file to use. It is not recommended that this option be used, as the default behavior of using the system-wide default policy (frequently /etc/containers/policy.json) is most often preferred.
--quiet
When writing the output image, suppress progress output.
EXAMPLE
This example extracts the imageID image to a local directory in docker format.
# buildah push imageID dir:/path/to/image
This example extracts the imageID image to a local directory in oci format.
# buildah push imageID oci:/path/to/layout
This example extracts the imageID image to a container registry named registry.example.com
# buildah push imageID docker://registry.example.com/repository:tag
This example extracts the imageID image and puts into the local docker container store
# buildah push imageID docker-daemon:image:tag
This example extracts the imageID image and pushes it to an OpenShift(Atomic) registry
# buildah push imageID atomic:registry.example.com/company/image:tag
