Will this sequence of steps completely delete an image from disk in the Docker Trusted Registry?

Solution. Delete the image and remove permissions to the repository in the Docker

Trusted Registry.

A.

Yes

Answers
A.

Yes

B.

No

Answers
B.

No

Suggested answer: B

Explanation:

The sequence of steps will not completely delete an image from disk in the Docker Trusted Registry. Deleting the image and removing permissions to the repository will only remove the image from the registry's user interface and prevent unauthorized access to it.However, the image data will still remain on the registry's storage backend until garbage collection is performed1.Garbage collection is a process that removes unused blobs (layers) from the registry's storage2.To run garbage collection, the registry must be stopped and the commandbin/registry garbage-collect /etc/docker/registry/config.ymlmust be executed3.Alternatively, the registry can be configured to run garbage collection automatically at regular intervals4.Reference:
