Docker部署cAdvisor

docker run -d 
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:ro \ 
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:ro \ 
--volume=/dev/disk/:/dev/disk:ro \
--publish=8080:8080 \
--detach=true \
--name=cadvisor \ 
google/cadvisor:latest

 

cAdvisor 每台主机都需要部署 

 

 

Docker部署Grafana

docker run -d \
--name=grafana \ 
-p 3000:3000 \
grafana/grafana

Docker部署Prometheus

 

docker run -d \
--name=prometheus \ 
-p 9090:9090 \ 
-v /tmp/prometheus.yml:/etc/prometheus/prometheus.yml \
