docker - 无法使用 docker (prom/prometheus) 加载 prometheus.yml 配置文件

Question

我正在尝试使用以下自定义 conf 文件通过 docker 加载 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

该文件已经存在。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": couldn't load configuration (--config.file="/prometheus-data/prometheus.yml"): open /prometheus-data/prometheus.yml: no such file or directory"

我正在遵循本指南:

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

我该怎么做才能正确加载此文件？

“文件已经存在”是指文件在您的主机上/prometheus-data/prometheus.yml吗？ ?如果是这样，那么您需要将它绑定(bind)到您的容器中，以便 Prometheus 可以访问它。

sudo docker run -p 9090:9090 -v /prometheus-data/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus

它包含在 Volumes & bind-mount 下在文档中。
