rometheus（18）：通过prometheus在centos7监控docker容器
·
一 安装docker
1.1 更新yum源
vim /etc/yum.repos.d/docker-ce.repo
修改第一个源为
[docker-ce-stable]
name=Docker CE Stable - x86_64
baseurl=https://mirrors.aliyun.com/docker-ce/linux/centos/9/x86_64/stable/
enabled=1
gpgcheck=1
gpgkey=https://mirrors.aliyun.com/docker-ce/linux/centos/gpg
1.2 找docker镜像的仓库
我这里选择了轩辕镜像的免费版
vim /etc/docker/daemon.json
然后选择这个轩辕镜像
{
"registry-mirrors": ["https://docker.xuanyuan.me"]
}
1.3 rocky采用的是二代CPU内核的形式
1.3.1 centos7
[root@centos7-3 scripts]# stat -fc %T /sys/fs/cgroup/
tmpfs
您在 /var/spool/mail/root 中有新邮件
[root@centos7-3 scripts]#
1.3.2 rocky9
[root@rocky9-1 ~]# stat -fc %T /sys/fs/cgroup/
cgroup2fs
1.3.3 最后采用tmps架构的centos7。部署docker和cAdvisor

二 下载
要监控docker状态，需要使用一个软件cAdvisor
cadvisor不仅可以搜集一台机器上所有运行的容器信息，还提供基础查询界面和http接口，方便其他组件如Prometheus进行数据抓取。
2.1 拉镜像的日志
在脚本里面已经拉下来了镜像
[root@centos7-3 scripts]# vim install_docker_cadvisor_centos7.sh
[root@centos7-3 scripts]# chmod +x install_docker_cadvisor_centos7.sh
[root@centos7-3 scripts]# /install_docker_cadvisor_centos7.sh
-bash: /install_docker_cadvisor_centos7.sh: 没有那个文件或目录
[root@centos7-3 scripts]# ./install_docker_cadvisor_centos7.sh
=== CentOS 7 Docker 安装和 cAdvisor 部署脚本 ===
步骤 1: 卸载旧版本 Docker（如果存在）
已加载插件：fastestmirror
不删除任何软件包

步骤 9: 测试 Docker 运行
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
17eec7bbc9d7: Pull complete
Digest: sha256:54e66cc1dd1fcb1c3c58bd8017914dbed8701e2d8c74d9262e26bd9cc1642d31
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

步骤 10: 检查 cgroup 版本（CentOS 7 通常使用 cgroups v1）
检测到 cgroups v1，适合运行 cAdvisor
步骤 11: 部署 cAdvisor 容器
使用适用于 cgroups v1 的 cAdvisor 配置

步骤 12: 等待 cAdvisor 启动
步骤 13: 检查 cAdvisor 状态
✅ cAdvisor 容器运行正常
325b8cf289f6 google/cadvisor:latest "/usr/bin/cadvisor -…" 12 seconds ago Up 10 seconds 0.0.0.0:8080->8080/tcp, :::8080->8080/tcp cadvisor
步骤 14: 测试 cAdvisor Web 界面
✅ cAdvisor Web 界面可以正常访问
🌐 请在浏览器中访问: http://192.168.80.133:8080
步骤 15: 显示 cAdvisor 日志（最后10行）
--- cAdvisor 日志 ---
=== 安装完成 ===
Docker 版本: Docker version 26.1.4, build 5650f9b
cAdvisor 访问地址: http://192.168.80.133:8080
常用命令：
查看容器状态: docker ps
查看 cAdvisor 日志: docker logs cadvisor
重启 cAdvisor: docker restart cadvisor
停止 cAdvisor: docker stop cadvisor
启动 cAdvisor: docker start cadvisor
如果遇到问题，请检查：
1. 防火墙设置: firewall-cmd --list-ports

2.2 拉成功的界面
2.3 也有拉到监控的界面
http://192.168.80.133:8080/metrics
2.4 部署node-exporter监控主机
2.4.1 docker run拉镜像并运行
[root@centos7-3 scripts]# docker run -d \
> --name=node-exporter \
> --restart=always \
> -p 9100:9100 \
> -v /proc:/host/proc:ro \
> -v /sys:/host/sys:ro \
> -v /:/rootfs:ro \
> prom/node-exporter \
> --path.procfs=/host/proc \
> --path.sysfs=/host/sys \
> --collector.filesystem.ignored-mount-points="^/(sys|proc|dev|host|etc)($|/)"
2.4.2 检测服务是否启动
[root@centos7-3 scripts]# docker ps

2.4.5 查看web上访问node exporter界面
http://192.168.80.133:9100/metrics
点开metrics看的话。都是一些监控指标
三 纳入prometheus
3.1 修改prometheus.yml
加入这次带检测的docker服务,prometheus的配置文件需要保持对齐
# JOB 12：配置文件 添加了docker容器相关的检测
- job_name: 'docker'
static_configs:
- targets: ['192.168.80.133:8080']
labels:
instance: docker-test
配置完成，重启prometheus
采用优雅重启的方式
curl -X POST http://localhost:9090/-/reload
3.2 发现多了docker这个监控指标
