Docker image on Docker Hub?

Hi. Is there a public Docker image published on Docker Hub or any other repository?

If not, I would like to work on a workflow to publish the Docker image every time a new version is published.

Just give me the following things:

• What registry should the image be pushed to?
• When should it be pushed? When a new tag is published, or when a new release is published?

By the way, I just checked that this project doesn't follow any version specification. I suggest that new versions are publicly available using tags and releases. It would be great they follow the semantic versioning specification.
