  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
    static_configs:
    - targets: ['docker.for.mac.host.internal:9003']

docker 调用宿主机服务，使用 docker.for.mac.host.internal 作为host
