EC2 Autoscale mentions Docker Machine but this is deprecated

I’m looking to configure Gitlab runners in AWS but when I look at the documentation for autoscaling in EC2 it references Docker Machine. Autoscaling GitLab Runner on AWS EC2 | GitLab

The link to docker machine says that this has now been deprecated. Is there updated guides/documentation on how to set this up?

I’d also be open to just using the Fargate implementation but I need to be able to set the docker image that should be used for the build in the gitlab ci file and as far as I can tell that requires the docker executor which apparently Fargate doesn’t support. (Note, I just want to specify the image that should be used for build, not build a docker image)

If someone could point me in the right direction that would be great.
