* Automated multi-arch build
This setup uses GitHub Actions to build an image for arm/v7 and arm64 then publish them on DockerHub (you need to setup repo secrets first) every time you want (workflow_dispatch), every push, every pull requests (pull_requests), or on a schedule (cronjob) :)
Remove the triggers you don't want.
Reminder: if you ever move the Dockerfile (or some dependencies), you will have to correct the Dockerfile path (and/or the context path).
* Create dependabot.yml
This checks the dependencies' versions for the Actions everyday and creates a pull request if there are new versions available.
