Container Registry:Create a repository and build images

Precautions

For example, you can specify a publicly accessible Internet image of the Container Registry Personal Edition instance as the base image in the Dockerfile. However, you cannot specify an image that is provided by a third party.

Features

• Automatically build images when code changes

  After you turn on Automatically Build Images When Code Changes, an image is automatically built each time you commit the code. This reduces manual workload.

  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. In the left-side navigation pane of the management page of the Personal Edition instance, choose Repository > Repositories.

  6. On the Repositories page, find the repository that you want to manage and click Manage in the Actions column.

  7. In the left-side navigation pane, click Build. On the page that appears, turn on Automatically Build Images When Code Changes.

  

• Build images on servers outside the Chinese mainland

  The source code used for image building may be stored in a source code repository outside the Chinese mainland. Container Registry provides the Build With Servers Deployed Outside Chinese Mainland feature to help you build images from repositories outside the Chinese mainland. After an image is built on a server outside the Chinese mainland, the image is pushed to a repository in the specified region.

  Note

  Image pushes may time out if the cross-border network connection is unstable.

  

• Build images without using cache

  After you turn on Build Without Cache, Container Registry pulls the base image from the source code repository each time you build an image. This may slow down the building process. We recommend that you turn off the switch.

• Multi-stage building

  Container Registry supports multi-stage building.

Step 1: Bind a source code repository

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. In the left-side navigation pane of the management page of the Container Registry Private Edition instance, choose Repository > Code Source.

6. On the Code Source page, find GitHub and click Bind Account in the Actions column.

7. In the GitHub dialog box, click Go to the source code repository to bind account.

8. On the GitHub logon page, enter your username and password, and then click Sign in.

   You are redirected to the Container Registry console and the following message appears: You have successfully bound the GitHub account.

Step 2: Create an image repository

Before you create an image repository, make sure that a namespace is created in the specified region. For more information, see Manage namespaces.

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. In the left-side navigation pane of the management page of the Personal Edition instance, choose Repository > Repositories.

6. On the Repositories page, click Create Repository.

7. In the Repository Info step, configure Namespace, Repository Name, Repository Type, and Summary. In this example, select Private for Repository Type. Then, click Next.

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

   Parameter	Description
   Code Source	Select the code source. In this example, GitHub is selected. Click the GitHub tab and then select the namespace and repository.
   Build Settings	Automatically Build Images When Code Changes: An image is automatically built 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 an image repository in the specified region. If the resources such as the source code repository and container image repository that you use to build the image are deployed in the Chinese mainland, we recommend that you disable the Build With Servers Deployed Outside Chinese Mainland feature to use servers deployed in the Chinese mainland. Build Without Cache: The system pulls the base image from the source code repository each time an image is built. This may increase the building duration. You can disable Build Without Cache to accelerate the image building.

Step 3: Configure building rules

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. In the left-side navigation pane of the management page of the Personal Edition instance, choose Repository > Repositories.

6. On the Repositories page, find the repository that you want to manage and click Manage in the Actions column.

7. In the left-side navigation pane of the repository management page, click Build. In the Build Rules section, click Add Build Rule.

   Note

   If you want to modify a building rule, select the rule that you want to modify and click Modify in the Actions column.

8. In the Add Build Rule dialog box, configure the building rule and click Confirm.

   Parameter	Description
   Type	The type of the source code repository. Valid values: Branch and Tag.
   Code Branch/Tag	The code branch or tag that triggers the building rule.
   Build Context Directory	The directory of the Dockerfile. This is a subdirectory of the branch or tag directory. For example, if the branch directory is Master/ and the Dockerfile is in the Master/ directory, the value of this parameter is Master/Dockerfile.
   Dockerfile Filename	The name of the Dockerfile. Default value: Dockerfile.
   Tags	The tag of the image. Example: latest.

Step 4: Build an image

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. In the left-side navigation pane of the management page of the Personal Edition instance, choose Repository > Repositories.

6. On the Repositories page, find the repository that you want to manage and click Manage in the Actions column.

7. In the left-side navigation pane of the repository management page, click Build.

8. In the Build Rules section, select the building rule that you want to use and click Build in the Actions column.

   After the building rule is built, a building record is generated.

   Note

   Select the building record that you want to view and click Log in the Actions column to view the building log.

9. After the image is built, click Tags in the left-side navigation pane to view the created images.

10. To view all images, click Build in the left-side navigation pane. On the Build Settings section of the page that appears, turn on Build with Servers Deployed Outside Chinese Mainland and Build Without Cache and remain the default enabled status of Automatically Build Images When Code Changes. Then, click Tags in the left-side navigation pane to view all image tags.
