我正在尝试使用以下自定义conf文件加载带有docker的prometheus：**danilo@machine:/prometheus-data/prometheus.yml**：

global:
  scrape_interval:     15s # By default, scrape targets every 15 seconds.

  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
    monitor: 'codelab-monitor'

  # A scrape configuration containing exactly one endpoint to scrape:
  # Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # Override the global default and scrape targets from this job every 5 seconds.
    scrape_interval: 5s

    static_configs:
      - targets: ['localhost:9090']

      - targets: ['localhost:8083', 'localhost:8080']
        labels: my_app
      group: 'my_app_group'

使用以下命令：

$ sudo docker run -p 9090:9090 prom/prometheus --config.file=/prometheus-
  data/prometheus.yml

文件已经存在。但是，我收到以下消息：
level=error ts=2018-09-26T17：45：00.586704798Z caller=main.go：617 err=“error loading config from“/prometheus-data/prometheus.yml”：无法加载配置（--config.file="/prometheus-data/prometheus.yml”）：打开/prometheus-data/prometheus.yml：没有这样的文件或目录”
我遵循以下指南：

• https://prometheus.io/docs/prometheus/latest/installation/

如何正确加载此文件？
