How Do I Resolve the Image Pull Failure During a Build Task?

Symptoms

When a build task is executed, the following error information is displayed in the log:

 ERROR: docker pull image failed, dockerImage

Cause Analysis

The possible causes are as follows:

• The network is abnormal. As a result, the pull times out.
• The image to be pulled does not exist.
• The pulled image is private.

Solution

• If the fault is caused by a network exception, perform the following operations to rectify the fault:
  1. Try again to check whether the problem can be solved.
  2. If the problem occurs frequently or the retry still fails, contact customer service.
• The image does not exist. Ensure that the image has been uploaded to the image repository and the image name and version are correct.
• If the image is private, set the image to be public, or perform the docker login authentication, and perform the docker pull operation.
