Chapter 6. Red Hat Quay repository overview
A repository provides a central location for storing a related set of container images. These images can be used to build applications along with their dependencies in a standardized format.
Repositories are organized by namespaces. Each namespace can have multiple repositories. For example, you might have a namespace for your personal projects, one for your company, or one for a specific team within your organization.
With a paid plan, Quay.io provides users with access controls for their repositories. Users can make a repository public, meaning that anyone can pull, or download, the images from it, or users can make it private, restricting access to authorized users or teams.
The free tier of Quay.io does not allow for private repositories. You must upgrade to a paid tier of Quay.io to create a private repository. For more information, see "Information about Quay.io pricing".
There are two ways to create a repository in Quay.io: by pushing an image with the relevant podman command, or by using the Quay.io UI. You can also use the UI to delete a repository.
If you push an image through the command-line interface (CLI) without first creating a repository on the UI, the created repository is set to Private, regardless of the plan you have.
It is recommended that you create a repository on the Quay.io UI before pushing an image. Quay.io checks the plan status and does not allow creation of a private repository if a plan is not active.
6.1. Creating a repository by using the UI
Use the following procedure to create a repository using the Quay.io UI.
Procedure
Use the following procedure to create a repository using the v2 UI.
Procedure
- Click Repositories on the navigation pane.
- Click Create Repository.
Select a namespace, for example, quayadmin, and then enter a Repository name, for example,
testrepo.ImportantDo not use the following words in your repository name: *
build*trigger*tagWhen these words are used for repository names, users are unable access the repository, and are unable to permanently delete the repository. Attempting to delete these repositories returns the following error:
Failed to delete repository <repository_name>, HTTP404 - Not Found.Click Create.
Now, your example repository should populate under the Repositories page.
-
Optional. Click Settings
Repository visibility Make private to set the repository to private.
6.2. Creating a repository by using Podman
With the proper credentials, you can push an image to a repository using Podman that does not yet exist in your Quay.io instance. Pushing an image refers to the process of uploading a container image from your local system or development environment to a container registry like Quay.io. After pushing an image to your registry, a repository is created. If you push an image through the command-line interface (CLI) without first creating a repository on the UI, the created repository is set to Private.

Use the following procedure to create an image repository by pushing an image.
Prerequisites
-
You have download and installed the
podmanCLI. - You have logged into your registry.
- You have pulled an image, for example, busybox.
Procedure
Pull a sample page from an example registry. For example:
$ podman pull busybox
Example output
Trying to pull docker.io/library/busybox... Getting image source signatures Copying blob 4c892f00285e done Copying config 22667f5368 done Writing manifest to image destination Storing signatures 22667f53682a2920948d19c7133ab1c9c3f745805c14125859d20cede07f11f9
Tag the image on your local system with the new repository and image name. For example:
$ podman tag docker.io/library/busybox quay.io/quayadmin/busybox:test
Push the image to the registry. Following this step, you can use your browser to see the tagged image in your repository.
$ podman push --tls-verify=false quay.io/quayadmin/busybox:test
Example output
Getting image source signatures Copying blob 6b245f040973 done Copying config 22667f5368 done Writing manifest to image destination Storing signatures
6.3. Deleting a repository by using the UI
You can delete a repository directly on the UI.
Prerequisites
- You have created a repository.
Procedure
-
On the Repositories page of the v2 UI, check the box of the repository that you want to delete, for example,
quayadmin/busybox. - Click the Actions drop-down menu.
- Click Delete.
Type confirm in the box, and then click Delete.
After deletion, you are returned to the Repositories page.
6.4. User settings
The User Settings page provides users a way to set their email address, password, account type, set up desktop notifications, select an avatar, delete an account, adjust the time machine setting, and view billing information.
6.4.2. Adjusting user settings
Use the following procedure to adjust user settings.
Procedure
- To change your email address, select the current email address for Email Address. In the pop-up window, enter a new email address, then, click Change Email. A verification email will be sent before the change is applied.
- To change your password, click Change password. Enter the new password in both boxes, then click Change Password.
- Change the account type by clicking Individual Account, or the option next to Account Type. In some cases, you might have to leave an organization prior to changing the account type.
- Adjust your desktop notifications by clicking the option next to Desktop Notifications. Users can either enable, or disable, this feature.
You can delete an account by clicking Begin deletion. You cannot delete an account if you have an active plan, or if you are a member of an organization where you are the only administrator. You must confirm deletion by entering the namespace.
ImportantDeleting an account is not reversible and will delete all of the account’s data including repositories, created build triggers, and notifications.
- You can set the time machine feature by clicking the drop-box next to Time Machine. This feature dictates the amount of time after a tag is deleted that the tag is accessible in time machine before being garbage collected. After selecting a time, click Save Expiration Time.
6.4.3. Billing information
You can view billing information on the User Settings. In this section, the following information is available:
- Current Plan. This section denotes the current plan Quay.io plan that you are signed up for. It also shows the amount of private repositories you have.
- Invoices. If you are on a paid plan, you can click View Invoices to view a list of invoices.
- Receipts. If you are on a paid plan, you can select whether to have receipts for payment emailed to you, another user, or to opt out of receipts altogether.
