Within your repository, you can give others access to push and pull to your repository, and you can assign permissions. You can also view your repository tags and the associated images.
A collaborator is someone you want to give access to a private repository. Once designated, they can
pull to your repositories. They're not
allowed to perform any administrative tasks such as deleting the repository or changing its status from private to public.
Only personal account repositories can use collaborators. You can add unlimited collaborators to public repositories, and Docker Pro accounts can add up to 1 collaborator on private repositories. Organization repositories can't use collaborators. Organization owners can control repository access with member roles and teams.
You can choose collaborators and manage their access to a private repository from that repository's Settings page.
A collaborator can't add other collaborators. Only the owner of the repository has administrative access.
You can also assign more granular collaborator rights ("Read", "Write", or "Admin") on Docker Hub by using organizations and teams. For more information see the organizations documentation.
You can view the available tags and the size of the associated image. Go to the Repositories view and select a repository to see its tags. To view individual tags, select the Tags tab.
To delete a tag, select the corresponding checkbox and select Delete from the Action drop-down list.
Only a user with administrative access (owner or team member with Admin permission) over the repository can delete tags.
You can select a tag's digest to access more details.
Image sizes are the cumulative space taken up by the image and all its parent
images. This is also the disk space used by the contents of the
created when you
docker save an image.
An image is stale if there has been no push or pull activity for more than one month. A multi-architecture image is stale if all single-architecture images part of its manifest are stale.
You can search the Docker Hub registry through its search interface or by using the command line interface. You can search by image name, username, or description:
$ docker search centos
NAME DESCRIPTION STARS OFFICIAL AUTOMATED
centos The official build of CentOS. 1034 [OK]
ansible/centos7-ansible Ansible on Centos7 43 [OK]
tutum/centos Centos image with SSH access. For the root... 13 [OK]
In the previous example, you can see two example results,
The second result shows that it comes from the public repository of a user,
ansible/, while the first result,
centos, doesn't explicitly list a
repository which means that it comes from the top-level namespace for
Docker Official Images.
/ character separates a user's repository from the image name.
Once you've found the image you want, you can download it with
docker pull <imagename>:
$ docker pull centos
latest: Pulling from centos
6941bfcbbfca: Pull complete
41459f052977: Pull complete
fd44297e2ddb: Already exists
centos:latest: The image you are pulling has been verified. Important: image verification is a tech preview feature and should not be relied on to provide security.
Status: Downloaded newer image for centos:latest
You now have an image from which you can run containers.
Stars are a way to show that you like a repository. They're also an easy way of bookmarking your favorites.
