docker-compose 部署jmeter+grafana+prometheus/influxdb，构建性能测试可视化实时监控（一）

docker-compose 部署grafana，prometheus

从grafana和prometheus官网拿到docker-compose.yml（下面有链接，进入后直接搜docker-compose.yml 就可以找到），然后放一起，如下图，作为compose启动的配置文件docker-compose.yml

[root@kpc]# cat docker-compose.yml 
version: "3"
services:
  grafana:
    image: grafana/grafana:5.1.0
    ports:
      - 3000:3000
    user: "104"
  prometheus:
    image: prom/prometheus:latest
    container_name: prometheus
    ports:
    - 9090:9090
    command:
    - --config.file=/etc/prometheus/prometheus.yml
    volumes:
    - ./prometheus.yml:/etc/prometheus/prometheus.yml:ro
    depends_on:
    - cadvisor
  cadvisor:
    image: gcr.io/cadvisor/cadvisor:latest
    container_name: cadvisor
    ports:
    - 8080:8080
    volumes:
    - /:/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:
    - 6380:6379

https://prometheus.io/docs/guides/cadvisor/#prometheus-configuration

只有docker-compose.yml还不够，启动会报错的，因为prometheus有个volumes配置

    volumes:
    - ./prometheus.yml:/etc/prometheus/prometheus.yml:ro

意思是把虚拟机当前目录下的prometheus.yml文件映射到prometheus服务容器里面的/etc/prometheus/prometheus.yml，所以，我们还要在当前目录建一个prometheus.yml，写入内容

scrape_configs:
- job_name: cadvisor
  scrape_interval: 5s
  static_configs:
  - targets:
    - cadvisor:8080

现在就齐活了，看一下当前目录都有啥？嗯， 就这2个文件

[root@kpc]# ls
docker-compose.yml  prometheus.yml

现在我们再up，发现报错了，看报错是拉取cadvisor时连接超时了，这是因为国外源的原因，马上换一下docker源，换成aliyun的，怎么替换docker源？

sudo mkdir -p /etc/docker  # 如果没有就新建，有的话直接进去然后下一步
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://tjtr2dh5.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

OK，源也换了，理论上没问题了。

docker-compose up启动，启动成功的日志太长就不贴了

docker-compose ps查看一下，如图，State都是up说明都成功了

[root@kpc]# docker-compose ps
       Name                     Command               State           Ports
