1. Execute command below to check if the image exists

   kubectl describe pod {报错的 pod}
   

2. Confirm whether you have pull permissions for the image repository. PolarDB-X's default image repository does not require permissions. If an internal image repository is used, authentication information needs to be configured; refer to the documentation: Pull an Image from a Private Registry
3. After confirming step 2, delete the pod that is reporting errors to allow it to be rebuilt.
