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 加载普罗米修斯：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": couldn't load configuration (--config.file="/prometheus-data/prometheus.yml"): open /prometheus-data/prometheus.yml: no such file or directory"

我正在遵循此指南：

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

如何才能正确加载此文件？

Answer 1

“文件已经存在”是指该文件位于 /prometheus-data/prometheus.yml 的主机上吗？如果是这样，那么您需要将其绑定安装到您的容器中，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

它在文档的 Volumes & bind-mount 下进行了介绍。

Answer 2

我正在使用 docker-compose.yaml，我也遇到了同样的问题。我必须按如下方式设置音量详细信息。

  prometheus:
    image: prom/prometheus:v2.26.0
    user: root
    ports:
      - 9090:9090
    volumes:
      - /apps/prometheus/configs/prometheus.yaml:/etc/prometheus/prometheus.yaml
      - /data/prometheus:/prometheus
    command: --web.enable-lifecycle --config.file=/etc/prometheus/prometheus.yml

Answer 3

您需要在 docker 上安装卷。 @Udara 的解决方案很好，但命令出错。

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

别忘了在文件夹/prometheus-data

下添加prometheus.yml文件
