1.cAdvisor是什么

cAdvisor是專門用來采集數(shù)據(jù)的工具。

cadvisor使用流程

2.Docker下cadvisor環(huán)境安裝

1.拉取官方鏡像google/cadvisor
[root@ecs-429b ~]$>docker pull google/cadvisor

2.創(chuàng)建容器google/cadvisor
[root@ecs-429b ~]$>docker run -itd --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=8081:8080 --detach=true --name=cadvisor google/cadvisor

3.Docker下prometheus環(huán)境安裝

更多prometheus的詳細(xì)內(nèi)容，參考網(wǎng)址：http://www.reibang.com/writer#/notebooks/50037693/notes/87166367

1.拉取prom/prometheus鏡像
[root@ecs-429b ~]$> docker pull prom/prometheus
2.創(chuàng)建prometheus目錄冷溃，新增prometheus.yml文件沙庐，用于指定設(shè)置docker地址:mkdir -p /opt/prometheus镀梭、vi /opt/prometheus/prometheus.yml
3.創(chuàng)建prometheus容器屋确，指定端口瘤睹、名稱舌胶、掛載目錄捆蜀、設(shè)置時區(qū):
docker run -itd --name prometheus -p 9090:9090
-v /opt/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml
-v /etc/localtime:/etc/localtime:ro
prom/prometheus

>4.修改配置文件后，重啟prometheus幔嫂，即重啟服務(wù)就是重啟容器：docker restart prometheus
>對應(yīng)第二步辆它，新建yaml文件并修改：vi /opt/prometheus/prometheus.yml
global:
  scrape_interval:     60s
  evaluation_interval: 60s
scrape_configs:
  - job_name: prometheus
    static_configs:
      - targets: ['172.17.0.1:9090']  #dokcer安裝的宿主機(jī)對應(yīng)的ip，比如10.100.10.15
        labels:
          instance: prometheus
  - job_name: linux
    static_configs:
      - targets: ['172.17.0.1:9100'] #dokcer安裝的宿主機(jī)對應(yīng)的ip履恩，比如10.100.10.15
  - job_name: mysql
    static_configs:
      - targets: ['172.17.0.1:9104'] #dokcer安裝的宿主機(jī)對應(yīng)的ip锰茉，比如10.100.10.15
  - job_name: 'cadvisor'
    static_configs:
      - targets: ['172.17.0.1:8081'] #dokcer安裝的宿主機(jī)對應(yīng)的ip，比如10.100.10.15

>對應(yīng)第三步切心，創(chuàng)建prometheus并創(chuàng)建容器
docker run -itd --name prometheus -p 9090:9090  \
  -v /opt/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml  \
  -v /etc/localtime:/etc/localtime:ro \
  prom/prometheus

4.Docker下grafana環(huán)境安裝

grafana容器搭建操作步驟
1.創(chuàng)建grafana目錄：
mkdir -p /opt/grafana/data
chmod 777 /opt/grafana/data
2.拉取官方的grafana鏡像：docker pull grafana/grafana
3.運(yùn)行容器飒筑，端口映射，用于外網(wǎng)訪問：

docker run -itd  --name=grafana  -p 3000:3000  \
  -v /opt/grafana/data:/var/lib/grafana  \
  -v /etc/localtime:/etc/localtime:ro \
  grafana/grafana

4.進(jìn)入容器：docker exec -it e7eeb8be6171 /bin/bash
5.輸入對應(yīng)的網(wǎng)址+端口绽昏，訪問容器协屡，用戶名/密碼的默認(rèn)值為admin/admin：http://10.100.10.16:3000/login
