Container Registry:Push images to and pull images from a Container Registry Personal instance

Step 1: Obtain the username that you use to log on to the Container Registry Personal Edition instance

• If you use an Alibaba Cloud account, the name of the Alibaba Cloud account is the username that you use to log on to the Container Registry Personal Edition instance.

• If you use a RAM user, the string before aliyundoc.com is the username that you use to log on to the Container Registry Personal Edition instance. For example, if the name of your RAM user is 28768383240243****@aliyundoc.com, the username that you use to log on to the Container Registry Personal Edition instance is 28768383240243****.

Step 2: Set a password that you use to log on to the Container Registry Personal Edition instance

1. Log on to the Container Registry console.

2. Click Reset Docker Login Password.

   Note

   If you forget the password that you set, you can use an access credential to reset a password.

3. In the Reset Docker Login Password dialog box, configure the Password and Confirm Password parameters and click Confirm.

Step 3: Create a namespace

You can manage a collection of repositories in a namespace. For example, you can manage permissions on repositories and modify repository attributes in a namespace.

1. Log on to the Container Registry console.

2. In the top navigation bar, select a region.

3. In the left-side navigation pane, click Instances.

4. On the Instances page, click the Personal Edition instance that you want to manage.

5. On the management page of the Container Registry Personal Edition instance, choose Repository > Namespace in the left-side navigation pane.

6. On the Namespace page, click Create Namespace.

7. In the Create Namespace dialog box, enter a name for the namespace and click Confirm.

Step 4: Create an image repository

1. Log on to the Container Registry console.

2. In the left-side navigation pane, click Instances.

3. On the Instances page, click the Personal Edition instance that you want to manage.

4. On the management page of the Container Registry Personal Edition instance, choose Repository > Repositories in the left-side navigation pane.

5. On the Repositories page, click Create Repository.

6. In the Repository Info step of the Create Repository wizard, configure the Namespace, Repository Name, Repository Type, Summary, and Description parameters, and then click Next.

   Note

   The repository name must be 2 to 64 characters in length and can contain lowercase letters, digits, underscores (_), hyphens (-), and periods (.). The name cannot start or end with an underscore (_) or contain forward slashes (/).

7. In the Code Source step, configure Code Source, Build Settings, and Build Rules, and then click Create Repository.

   Parameter	Description
   Code Source	The code source. Important Before you select a code source, ensure that the instance is bound to a source code hosting platform. For more information, see Bind a source code hosting platform.
   Build Settings	Automatically Build Images When Code Changes: The building rule is automatically triggered when code is committed from a branch. Build with Servers Deployed Outside Chinese Mainland: Images are built in a data center outside the Chinese mainland and then pushed to the image repository in the specified region. Build Without Cache: The system pulls the base image each time an image is to be built. This may slow down the building process.
   Build Rules	After the repository is created, go to the image building page to create image building rules. For more information, see Create a repository and build images.

Step 5: Push and pull an image

1. Run the following command to log on to the Container Registry Personal Edition instance:

   docker login --username=<Username that you use to log on to the Container Registry Personal Edition instance> registry.cn-<Region ID of the Container Registry Personal Edition instance>.aliyuncs.com

   Enter the logon password that you set in Step 2: Set a password that you use to log on to the Container Registry Personal Edition instance as prompted. If login succeeded is displayed, the logon is successful.

2. Push an image.

   1. Run the following command to tag the image:

      docker tag <Image ID> registry.cn-<Region in which the Personal Edition instance resides>.aliyuncs.com/<Namespace name>/<Image repository name>:<Image tag>

   2. Run the following command to push the image to the image repository on the Container Registry Personal Edition instance:

      docker push registry.cn-<Region in which the Personal Edition instance resides>.aliyuncs.com/<Namespace name>/<Image repository name>:<Image tag>

      On the Repositories page, click the name of the image repository. On the page that appears, click Tags. If the image name is displayed on the Tags page, the image is pushed to the image repository.

3. Run the following command to pull an image:

   docker pull registry.cn-<Region in which the Personal Edition instance resides>.aliyuncs.com/<Namespace name>/<Image repository name>:<Image tag>

   Run the docker images command. If the image name is displayed in the command output, the image is pulled from the image repository.

What to do next

Delete multiple image tags at a time

1. Log on to the Container Registry console.

2. In the top navigation bar, select a region.

3. In the left-side navigation pane, click Instances.

4. On the Instances page, click the Personal Edition instance that you want to manage.

5. On the management page of the Container Registry Personal Edition instance, choose Repository > Repositories. On the Repositories page, click the name of the repository whose tags you want to delete.

6. On the details page of the repository, click Tags in the left-side navigation pane.

7. On the Tags page, select the tags that you want to delete and then click Batch Delete.
