must be set to `docker+machine`. Most of those settings are taken care of when
you register the Runner for the first time.
`limit` defines how many jobs can be handled concurrently by this token.
`limit` sets the maximum number of machines (running and idle) that this Runner
will start. For more info check the [relationship between `limit`, `concurrent`
and `IdleCount`](https://docs.gitlab.com/runner/configuration/autoscale.html#how-concurrent-limit-and-idlecount-generate-the-upper-limit-of-running-machines).

- `amazonec2-vpc-id=vpc-xxxxx` - Your VPC ID to launch the instance in, read more in [Docker docs about the VPC ID](https://docs.docker.com/machine/drivers/aws/#vpc-id).
- `amazonec2-subnet-id=subnet-xxxx` - AWS VPC subnet ID.
- `amazonec2-use-private-address=true` - Use the private IP address for docker-machine, but still create a public IP address. Useful to keep the traffic internal and avoid extra costs.
- `amazonec2-tags=Name,gitlab-runner-autoscale` - AWS extra tag key-value pairs, useful to identify the instances on the AWS console.
