基于docker 搭建Prometheus+Grafana的过程详解

1. 拉取依赖镜像

docker pull prom/node-exporter
docker pull prom/prometheus
docker pull grafana/grafana

2.分别启动各镜像

1. 启动node-exporter

   docker run -d -p 9100:9100 
    --name node-exporter 
    --restart=always  
    -v /opt/dockerData/node-exporter/proc:/host/proc:ro 
    -v /opt/dockerData/node-exporter/sys:/host/sys:ro 
    -v /opt/dockerData/node-exporter:/rootfs:ro 
    prom/node-exporter
   

2. 启动promethus

   docker run -d 
    --name prometheus 
    --restart=always 
    -u root 
    -p 9090:9090 
    -v /opt/dockerData/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml 
    -v /opt/dockerData/prometheus:/prometheus 
    -v /opt/dockerData/prometheus/conf:/etc/prometheus/conf 
    prom/prometheus
   

   prometheus.yml

   global:
     scrape_interval: 60s
     evaluation_interval: 60s
   
   scrape_configs:
     - job_name: prometheus
       static_configs:
         - targets:
             - 192.168.0.104:9090
   
     - job_name: node-exporter
       static_configs:
         - targets:
             - 192.168.0.104:9100
     - job_name: jenkins
       scheme: http
       metrics_path: prometheus
       bearer_token: bearer_token
       static_configs:
         - targets:
             - 192.168.57.242:8080
   

3. 启动grafana

   docker run -d 
    -p 3000:3000 
    --restart=always 
    --name=grafana 
    -u root 
    -v /opt/dockerData/grafana:/var/lib/grafana 
    grafana/grafana
   

3.登录grafana

默认用户名和密码均为admin，登录成功后修改默认密码
