[Feature Request]: docker-machine is deprecated, we need to add support for another tool for autoscaling

[gromain]

docker-machine is being deprecated and starts to be unavailable from repositories. It's also not compatible with the latest docker version. See docker/machine#4537 and docker/roadmap#245 .

One alternative would be to move towards Terraform. There is a provider for Scaleway, so we wouldn't lose functionality. Is there any interest in moving towards this solution?

What is the problem?

docker-machine being deprecated.

What should be the expected behavior?

Not losing the autoscale!

How can we reproduce this? (What steps did you do to trigger the problem? If applicable, please include multiple screenshots of the problem! Be detailed)

Try installing docker-machine on a recent OS.

A python alternative could be libcloud (I know this tool is written in JS, just mentioning this for posterity): https://libcloud.apache.org/

Definitely interested in possible approaches to migrate away from docker-machine, although docker-machine is open source, so it continues to receive support from various organizations (e.g. gitlab https://gitlab.com/gitlab-org/ci-cd/docker-machine) and has been working OK thus far, so I don't think we're losing autoscaling anytime soon.

[gromain]

Ah yes, this is good then!
Maybe we can just update the Readme to point to this new repo, instead of towards https://docs.docker.com/machine/install-machine/ . It was really confusing for me!

[gromain]

I've fixed the documentation, Dockerfile and docker-compose files.
This will do for now, but I suggest we keep this open to make sure the tool is not completely abandoned by Gitlab and we keep looking for another solution.

[pierotofy]

Thanks. As a heads up, I've reverted the docker-compose file changes since not everyone uses the autoscaling functionality (perhaps those changes should be part of a separate docker-compose file).

[gromain]

Oh I see, I thought the docker-composer file here was only for the autoscaler (since this was in the autoscaler section of the readme too and there is specific instructions about starting it up with one child nodeodm).
I'll create a separate one and update the readme accordingly.

@pierotofy Can we not migrate to Terraform? It is very widely supported.
