With both Docker daemons (minikube & docker-machine) the AWS Toolkit in Intellij IDEA ran a "docker ps" which was always complaining that the socket "/var/run/docker.sock" could not be found. Unfortunately this UNIX socket is only available with the Docker Desktop for MacOSX.
You can set DOCKER_HOST=unix:///your-docker-socket to point to your docker endpoint. (this makes the docker ps work, I'm using colima and it still fails on the next step)

There are currently more issues with the JetBrains Docker integration. docker-machine did not find a machine that was created: https://youtrack.jetbrains.com/issue/IDEA-237306/Docker-plugin-does-not-see-docker-machine-despite-it-is-in-standard-location-and-has-machines-running
So the only hassle free solution seems to be the Docker Desktop for MacOSX at the moment.
