#DOCKER RUN IMAGE AND ATTACH UPDATE#

Docker appears to update their master images on a fairly frequent basis. This can help us assess how "fresh" a particular build is.

CREATED: The date the repository was created, as opposed to when it was pulled.

Sometimes, such as when we commit a container without specifying a name or tag, the repository or the tag is, but we can always refer to a specific image or container using its ID.

IMAGE ID: This is like the primary key for the image.

Each of these versions is tagged with a version number, a name, and there's even a special tag called "latest" which represents the latest version. As we can see from the list, we've pulled down different versions of linux.

TAG: Tags represent a specific set point in the repositories' commit history.

REPOSITORY: The name of the repository, which in this case is "ubuntu".

The command, docker images, returns the following columns: Status: Downloaded newer image for centos:latestĬentos latest ae0c2d0bdc10 2 weeks ago 224 MB In Docker, versions are marked with tags.Ĭentos:latest: The image you are pulling has been verified
