After you delete image tags in the Container Registry console, the image tags still exist in an Object Storage Service (OSS) bucket. If you do not delete the image tags in the OSS bucket in time, you may be charged for additional costs. You can execute an artifact deletion task to delete the image tags from the OSS bucket to release the occupied storage space.
Precautions
You can clean up OSS buckets only for Container Registry Enterprise Edition instances. When you clean up OSS buckets for a Container Registry Enterprise Edition instance, expired image tags in all image repositories are deleted from OSS buckets. Expired chart tags in all chart repositories are not deleted from OSS buckets.
You cannot push images to image repositories while an artifact deletion task is being executed. However, you can still pull images from image repositories. After the artifact deletion task is completed, you can push images to image repositories.
