基於docker 搭建Prometheus+Grafana的過程詳解

1. 拉取依賴鏡像

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

2.分別啓動各鏡像

1. 啓動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. 啓動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
   

3. 啓動grafana

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

3.登錄grafana
