Please use correct docker tags for released versions

Is your feature request related to a problem? Please describe.
I currently use What's up Docker to monitor available updates to my containers. This, like many other container update tools depends on the container sha that changes between deployments, but a neat feature is that it is capable to get the tag name from the new image and parse a version number from it, making it possible for me to have a clear view of what versions are updating and even automatically link the related changelogs on GitHub. Currently MyIP is always pushing every new docker image just as latest and does not assign any version tags to these, which makes the process I described above impossible.

Having tags per version basis is also a good practice to make it easier for people that want to pin their environments for one specific version of a project or rollback to older releases.

Describe the solution you'd like
I would like to propose that the deployment process of MyIP pushes the docker images with tags related to the actual version.

It should work now.
