Question 1

How do I use Docker Hub Description with a personal access token?

Accepted Answer

Generate a Docker Hub Personal Access Token with read/write/delete scope and use it as the 'password' input in the workflow YAML. This is more secure than using a plain password, as mentioned in the README.

Question 2

Can Docker Hub Description handle multiple repositories at once?

Accepted Answer

No, it updates one repository per step; you need to configure separate steps or jobs for multiple repositories, each with its own credentials and repository input.

Question 3

What happens if my README is too big for Docker Hub?

Accepted Answer

The action truncates the content to fit the 25,000-byte limit and logs a warning. You may need to manually shorten your README to avoid losing documentation details.

Question 4

Docker Hub Description vs manually updating: which is better for infrequent changes?

Accepted Answer

For infrequent updates, manual control might be simpler to avoid automation overhead, but this action ensures consistency and reduces human error, making it ideal for active projects.

Question 5

Does it work with private Docker Hub repositories?

Accepted Answer

Yes, as long as you provide valid credentials with Admin permissions, it can update both public and private Docker Hub repositories, as noted in the username input description.

Question 6

How to trigger updates only on releases?

Accepted Answer

Configure the workflow to run 'on: release' in the YAML, as shown in the examples, which updates the description whenever a new release is created in GitHub.
