快速创建一个可用的 prometheus 和 grafana 进行测试， 并将数据保留在当前的目录中， 在重启之后数据不会丢失：

  1. 创建一个目录.

    mkdir /opt/monitor
mkdir /opt/monitor/grafana
mkdir /opt/monitor/grafana_data
mkdir /opt/monitor/prometheus
mkdir /opt/monitor/prometheus_data
touch /opt/monitor/docker-compose.yaml

  2. 创建docker-compose 文件

    ---
version: "3"
services:
  prometheus:
    container_name: prometheus
    image: reg.liarlee.site/docker.io/prom/prometheus:latest
    restart: always
    network_mode: host
    environment:
      - TZ=Asia/Shanghai
    volumes:
      # - /opt/monitor/prometheus/prometheus.yaml:/etc/prometheus/prometheus.yml
      - /opt/monitor/prometheus_data:/prometheus
    command:
      - '--config.file=/etc/prometheus/prometheus.yml'
      - '--storage.tsdb.path=/prometheus'
      - '--web.console.libraries=/usr/share/prometheus/console_libraries'
      - '--web.console.templates=/usr/share/prometheus/consoles'
      - '--storage.tsdb.retention.time=90d'
  grafana:
    container_name: grafana
    image: reg.liarlee.site/docker.io/grafana/grafana-oss:main-ubuntu
    restart: always
    network_mode: host
    environment:
      - TZ=Asia/Shanghai
    volumes:
      - /opt/monitor/grafana_data:/var/lib/grafana
      - /opt/monitor/grafana/datasource:/etc/grafana/provisioning/datasources
      # - /opt/monitor/grafana/grafana.ini:/etc/grafana/grafana.ini
      - /etc/localtime:/etc/localtime:ro
    user: '472'

  3. 准备基础配置文件

    docker compose up -d 
docker cp grafana:/etc/grafana/grafana.ini /opt/monitor/grafana/grafana.ini
docker cp prometheus:/etc/prometheus/prometheus.yml /opt/monitor/prometheus/prometheus.yaml

chown -R 472:472 /opt/monitor/grafana_data
chown -R 472:472 /opt/monitor/grafana

chown -R nobody:nobody /opt/monitor/prometheus_data
chown -R nobody:nobody /opt/monitor/prometheus

docker compose down --remove-orphans

  4. 准备prometheus 作为默认的Datasource

    touch /opt/monitor/grafana/datasource/datasource.yml
---
apiVersion: 1

datasources:
- name: Prometheus
  type: prometheus
  url: http://localhost:9090 
  isDefault: true
  access: proxy
  editable: true

  5. 修改配置文件中需要的参数, 取消配置文件中的注释， 然后重启即可。

    docker compose down --remove-orphans && docker compose up -d
