I wanted to know how pricing works with setup_remote_docker. If I have a paid plan with 2 containers, and I have setup_remote_docker in my circle.yml, then circle will spin up a remote environment to run docker/docker-compose related commands. Does that remote environment/container count against my quota ? e.g. If I have 2 containers plan, then when I trigger a build, will the remote environment be my second container? Or will I be able to concurrently trigger a second build?
