使用docker compose安装部署prometheus、cAdvisor、redis容器监控_wx643e285b660e7的技术博客_

一、创建项目目录，编辑Prometheus.yml主配置文件，添加监控的容器cAdvisor为目标容器

[root@localhost ~]# mkdir prom
[root@localhost ~]# cd prom
[root@localhost ~]# vi prometheus.yml
[root@localhost prom]# cat prometheus.yml |egrep -v "^([ ]*#)|^$"	#过滤掉注释和空行
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
alerting:
  alertmanagers:
    - static_configs:
        - targets:
rule_files:
scrape_configs:
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]
# 加入以下内容：
  - job_name: cadvisor
    scrape_interval: 5s
    static_configs:
      - targets:
        - cadvisor:8080
将prometheus.yml拷贝到/etc/prometheus/目录下
[root@localhost ~]# mkdir /etc/prometheus
[root@localhost ~]# cp prometheus.yml /etc/prometheus
二、编写docker-compose文件启动prom、cAdvisor、redis容器
[root@localhost prom]# vi docker-compose.yml
version: '3.2'
services:
  prometheus:
    image: prom/prometheus:latest
    container_name: prometheus
    ports:
    - 9090:9090
    command:
    - --config.file=/etc/prometheus/prometheus.yml		# 本机存放的配置文件路径，但感觉读的还是当前目录的文件,
    volumes:
    - ./prometheus.yml:/etc/prometheus/prometheus.yml:ro		# 只读挂载
    depends_on:
    - cadvisor		# 依赖容器，要先启动cadvisor容器
  cadvisor:
    image: gcr.io/cadvisor/cadvisor:latest		# gcr.io为谷歌云，国内访问不了，需提前准备
    container_name: cadvisor
    ports:
    - 8080:8080
    volumes:		# 挂载——获取其他容器信息的原因
    - /:/rootfs:ro
    - /var/run:/var/run:rw
    - /sys:/sys:ro
    - /var/lib/docker/:/var/lib/docker:ro
    depends_on:
    - redis
  redis:
    image: redis:latest
    container_name: redis
    ports:
    - 6379:6379
加载本地acdvisor软件包到本地
[root@localhost prom]# ls
cadvisor.tar  docker-compose.yml  prometheus.yml
[root@localhost prom]# docker load -i cadvisor.tar		# 加载镜像

切换到Prom目录启动容器
[root@localhost prom]# docker compose up -d
[+] Running 3/3
 ✔ Container redis       Started                                                                 0.4s 
 ✔ Container cadvisor    Started                                                                 0.7s 
 ✔ Container prometheus  Started                                                                 1.5s 
三、访问localhost:8080查看cadvisor的Web界面，访问 localhost:9090 查看Prom界面
cadvisor可以看到所有正在运行的容器即可
