Repositories and Images on Docker.io

Searching for repositories and images

You can search for all the publicly available repositories and images using Docker. If a repository is not public (i.e., private), it won't be listed on the repository search results. To see repository statuses, you can look at your profile page on Docker.io.

Repositories

Stars

Stars are a way to show that you like a repository. They are also an easy way of bookmark your favorites.

Comments

You can interact with other members of the Docker community and maintainers by leaving comments on repositories. If you find any comments that are not appropriate, you can flag them for the admins' review.

Private Docker Repositories

To work with a private repository on Docker.io, you will need to add one via the Add Repository link. Once the private repository is created, you can push and pull images to and from it using Docker.

Note: You need to be signed in and have access to work with a private repository.

Private repositories are just like public ones. However, it isn't possible to browse them or search their content on the public registry. They do not get cached the same way as a public repository either.

It is possible to give access to a private repository to those whom you designate (i.e., collaborators) from its settings page.

From there, you can also switch repository status (public to private, or viceversa). You will need to have an available private repository slot open before you can do such a switch. If you don't have any, you can always upgrade your Docker.io plan.

Collaborators and their role

A collaborator is someone you want to give access to a private repository. Once designated, they can push and pull. Although, they will not be allowed to perform any administrative tasks such as deleting the repository or changing its status from private to public.

Note: A collaborator can not add other collaborators. Only the owner of the repository has administrative access.

Webhooks

You can configure webhooks on the repository settings page. A webhook is called only after a successful push is made. The webhook calls are HTTP POST requests with a JSON payload similar to the example shown below.

Note: For testing, you can try an HTTP request tool like requestb.in.

Example webhook JSON payload:

{
   "push_data":{
      "pushed_at":1385141110,
      "images":[
         "imagehash1",
         "imagehash2",
         "imagehash3"
      ],
      "pusher":"username"
   },
   "repository":{
      "status":"Active",
      "description":"my docker repo that does cool things",
