cAdvisor：google開源的一個docker container監(jiān)控工具，自帶web ui乏苦，并支持導出到prometheus六荒、influxdb等存儲；
prometheus + grafana安裝看這里蝗砾。
安裝配置
cAdvisor
-
配置用戶名密碼
為cAdvisor web ui生成認證文件auth.htpasswd,用戶http basic認證:yum install -y httpd-tools htpasswd -b -c auth.htpasswd user1 password1 -
docker-compose配置
將auth.htpasswd與docker-compose.yml放到同一目錄下:version: '3.3' services: cadvisor: image: google/cadvisor:v0.33.0 ports: - "8030:8080" volumes: - /:/rootfs:ro - /var/run:/var/run:rw - /sys:/sys:ro #- /var/lib/docker/:/var/lib/docker:ro - /apps/data/docker/:/var/lib/docker:ro - /dev/disk/:/dev/disk:ro - /cgroup:/cgroup:ro - ./auth.htpasswd:/etc/auth.htpasswd command: - '--http_auth_file=/etc/auth.htpasswd' privileged: true devices: - /dev/kmsg 啟動并驗證
docker-compose up -d啟動先较，瀏覽器訪問cAdvisor web uihttp://{host}:8030，輸入用戶名密碼登錄悼粮，可以看到如下界面:
