If Docker encounters a label/key that already exists, the new value overrides any previous labels with identical keys. To view an image’s labels, use the docker inspect command. They will be under the 'Labels' JSON attribute. Reference - Best Practices. This Docker cheat sheet will give you a quick reference to the basics of Docker that you must know to get started with it.
