Running Docker Commands

login and logout

1. Search for and add action Run Docker Command.
2. Select login or logout for Command.
   

   Only self-hosted and SWR repositories are supported. You are advised to use the action Run Shell Commands to log in to or log out of a public repository.

   When running the login command, retain the default value No for Restart Docker.

   When you log in to a private repository, Docker provides a valid credential of the private repository in the .docker/config.json file. By default, the credential is encoded using Base64. You are advised to use docker-credential-pass and gpg to enhance Docker security.

3. Select the image repository to be logged in to or logged out of. If no image repository is available, click Create.

   The Create Service Endpoint: Docker repository dialog box is displayed, as shown in the following figure.

   

   Table 1 Parameters

   Parameter	Description
   Service Endpoint Name	Name of the service endpoint to the image repository. The name facilitates service endpoint selection and management.
   Repository Address	Address of the image repository. You can use a self-hosted or SWR repository. NOTE: The image repository address cannot contain the organization name or image name. The repository address is in the https://XXXX.com or http://XXXX.com format.
   Username	Username for logging in to the image repository.
   Password	Password for logging in to the image repository.

      • -u is followed by the username.
      • -p is followed by the password.
      • swr.XXXXX.com is the repository address.
   4. On the deployment page, add the service endpoint.

      

      

      The repository URL must be in the https://XXXX.com or http://XXXX.com format.

      The image repository address obtained by running the temporary command must be prefixed with https:// or http:.

   5. Click OK.

      Then you can run the login command to log in to the image repository on CodeArts Deploy.

5. To modify the information about an image repository, click Manage next to Image Repository in the action Run Docker Commands. On the displayed page, edit or delete the repository.
