Export

In Docker Trusted Registry, is this how a user can prevent an image, such as 'nginx:latest', from being overwritten by another user with push access to the repository?

Solution: Remove push access from all other users.

A.

Yes

Answers
A.

Yes

B.

No

Answers
B.

No

Suggested answer: B

Explanation:

While removing push access from all other users can prevent an image from being overwritten, it's not the only way and might not be the most efficient or practical solution, especially in a collaborative environment. Docker Trusted Registry (DTR) provides a feature called 'Immutable Tags' which can be used to prevent an image, such as 'nginx:latest', from being overwritten. Once a tag is marked as immutable, DTR will prevent any user from pushing the same tag to the repository, thus preserving the image. This allows for better version control and prevents accidental overwrites. Therefore, the solution to prevent an image from being overwritten is not just to remove push access from all other users, but to use the features provided by DTR like 'Immutable Tags'.
