It is very convenient to create Autobuild repositories on DockerHub linked to a Github repository with a Dockerfile. Then every time you commit to Github, Dockerhub is going to build the image on their service and make it available on https://hub.docker.com and can quickly be pulled to any other system that supports Docker or Singularity.
Unfortunately if you have many Github organizations and repositories, the process to set a new repository up gets stuck.
Fortunately we can bypass the issue by directly accessing the right URL, as suggested on StackOverflow.
I created a simple page to make this quicker, add the right parameters and it automatically builds the right URL, see:
