How to delete none tags by docker

None Tags can be deleted in batches by manually deleting unmarked images or using the Docker CLI plugin. Manual deletion involves finding unmarked images, getting the mirror ID, and then deleting the images. For batch deletion, you can use the command docker images -f dangling=true -q | xargs docker rmi to delete all unmarked images.

How to delete None Tag in Docker

None Tag is a special tag that marks unlabeled images that take up disk space and interfere with image management. The following methods can delete the None Tag in Docker:

Manually delete

1. Find unlabeled images: docker images | grep none
2. Get the image ID: docker inspect IMAGE_ID | jq -r '.Id'
3. Delete the image: docker rmi IMAGE_ID

Batch Delete

Use the following command to batch delete all unmarked images:

 <code>docker images -f dangling=true -q | xargs docker rmi</code>

Using the Docker CLI plugin

You can also use Docker CLI plug-in (such as docker-cleanup ) to automatically delete the None Tag. After installing and enabling the plugin, you can delete the None Tag using the following command:

 <code>docker-cleanup -f</code>

Notes:

• Make sure that the deleted image is not used by other containers or images, otherwise it may cause problems.
• If the deleted image contains important data, back up the data before deleting.
