NAME

buildah commit - Create an image from a working container.

SYNOPSIS

buildah commit [options [...]] containerID [imageName]

DESCRIPTION

Writes a new image using the specified container's read-write layer and if it is based on an image, the layers of that image. If an image name is not specified, an ID is assigned, but no name is assigned to the image.

OPTIONS

--cert-dir path

Use certificates at path (*.crt, *.cert, *.key) to connect to the registry

--creds creds

The username[:password] to use to authenticate with the registry if required.

--disable-compression, -D

Don't compress filesystem layers when building the image.

--format

Control the format for the image manifest and configuration data. Recognized formats include oci (OCI image-spec v1.0, the default) and docker (version 2, using schema format 2 for the manifest).

--quiet

When writing the output image, suppress progress output.

--rm Remove the container and its content after committing it to an image. Default leaves the container and its content in place.

--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.

--tls-verify bool-value

Require HTTPS and verify certificates when talking to container registries (defaults to true)

EXAMPLE

This example saves an image based on the container. buildah commit containerID

This example saves an image named newImageName based on the container. buildah commit --rm containerID newImageName

This example saves an image based on the container disabling compression. buildah commit --disable-compression containerID

This example saves an image named newImageName based on the container disabling compression. buildah commit --disable-compression containerID newImageName

This example commits the container to the image on the local registry while turning off tls verification. buildah commit --tls-verify=false containerID docker://localhost:5000/imageId

This example commits the container to the image on the local registry using credentials and certificates for authentication. buildah commit --cert-dir ~/auth --tls-verify=true --creds=username:password containerID docker://localhost:5000/imageId
