• Apply a CMD Dockerfile instruction to the created image:

docker commit --change="CMD {{command}}" {{container}} {{image}}:{{tag}}

• Apply an ENV Dockerfile instruction to the created image:

docker commit --change="ENV {{name}}={{value}}" {{container}} {{image}}:{{tag}}

• Create an image with a specific author in the metadata:

docker commit --author="{{author}}" {{container}} {{image}}:{{tag}}

• Create an image with a specific comment in the metadata:

docker commit --message="{{comment}}" {{container}} {{image}}:{{tag}}

• Create an image without pausing the container during commit:
