I have asked this before but never found the answer.  I have created my own docker in dockerhub using automated builds from github and set up a repository,  how does the update mechanism work? 

 

Check for updates never shows an update when I update my code in github.  Force update still works fine so not much of an issue but it still bugs me.

Sorry for not being exactly on topic, but my problem is to create a docker from dockerhub file, could you please make a quick tutorial?

Thanks in advance, TrueType
