k8s编排部署的方式部署Prometheus、node

• 1. 拉取google/cadvisor官方镜像
• 2. 将cadvsior镜像运行为容器
• 3. 修改Prometheus的配置文件

测试访问web界面，点击docker containers可以用来查看指定容器的详细信息

// 可以点击查看

// 使用上一篇博客的Prometheus的容器
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=` to any timeseries scraped from this config.
  - job_name: "prometheus"
  - job_name: "linux"
  - job_name: "cadvisor"  //要监控的对象
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ["localhost:9090"]
      - targets: ["192.168.182.151:9100"]
      - targets: ["192.168.182.151:8080"]  //添加要监控的主机

[root@master prometheus]# docker restart prometheus  //重启容器
