docker安装Prometheus+cAdvisor+Grafana

修改yml文件，加上docker和linux机器设备

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

配置文件信息

[root@k8s-master tmp]# cat prometheus.yml

  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
