Automation!

[dnil]

This repo is missing CI automation! Would be neat to add in GitHub Actions to update DockerHub!

You are welcome to open a PR to fix it! 😆

Could be done with an action like this perhaps? What it does:

• Loops thru all changed .yml files and builds a matrix with them
• Builds and pushes each image to Docker Hub

The problem is that you don't know which tag to push, apart from "latest"..

I haven't tested this, it's just a draft!

name: Build and push changed Docker images to Docker Hub

          push: true
          tags: "clinicalgenomics/${{steps.image_name.outputs.all}}:latest" #How do you get to know if you should push tag 1.0, 2.0 etc here?
