Docker+machine executor creating too many instances
Summary
Using then docker+machine executor creates too many machines:
- When the limit is set to 4, it initially creates 5 machine instances and then scales down to 4.
- When the limit is set to 1, it initially creates 2 machine instances and then scales down to 1.
- When the limit is not set, it creates 2 machine instances.
Steps to reproduce (limit = 4)
Save the following in gitlab-runner/config.toml:
concurrent = 10
check_interval = 1
[[runners]]
name = "runner-digitalocean-0"
limit = 4
url = "https://<gitlab-host>"
token = "cc70ebba48ed1b288af2..."
executor = "docker+machine"

privileged = false
disable_cache = true
volumes = ["/var/run/docker.sock:/var/run/docker.sock", "/cache"]
