docker-监控环境搭建.md

1.镜像使用(一体化)

1.1.镜像安装

• 手工配置

  docker stop monitor
  docker rm monitor
  docker run --name monitor --privileged=true -p 9090:9090  -p 3000:3000  -d wuhaocn/monitor:1.0
  docker update monitor --restart=always

• 自动发现

  docker stop monitor-consul
  docker rm monitor-consul
  docker run --name monitor-consul --privileged=true  -p 18500:8500  -p 19090:9090  -p 13000:3000  -d wuhaocn/monitor:2.0
  docker update monitor-consul --restart=always

• 注册节点信息

  curl -X PUT -d '{"id": "test1","name": "test1","address": "192.168.56.12","port": 9100,"tags": ["service"],"checks": [{"http": "http://192.168.56.12:9100/","interval": "5s"}]}' http://192.168.56.12:8502/v1/agent/service/register
  
  curl -X PUT -d '{"id": "test1","name": "test1","address": "192.168.56.12","port": 9100,"tags": ["service"],"checks": [{"http": "http://192.168.56.12:9100/","interval": "5s"}]}' http://192.168.56.12:8502/v1/agent/service/unregister

1.2.容器配置

docker exec -it monitor bash

1.3 配置生效

修改后重启配置

docker restart monitor

2.镜像使用(拆分)

2.1.安装

• 默认配置

docker stop prometheus
docker rm prometheus
docker run -d --name=prometheus  -p 9090:9090  prom/prometheus
docker update prometheus --restart=always

docker stop grafana
docker rm grafana
docker run -d --name=grafana  -p 3000:3000 grafana/grafana
docker update grafana --restart=always

• 修改配置

docker stop prometheus
docker rm prometheus
docker run -d --name=prometheus  -p 9090:9090  -v /home/rcloud/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus
docker update prometheus --restart=always

global:
  # 默认情况下，每15s拉取一次目标采样点数据。
  scrape_interval:     15s
  # 我们可以附加一些指定标签到采样点度量标签列表中, 用于和第三方系统进行通信, 包括：federation, remote storage, Alertmanager
  external_labels:
    # 下面就是拉取自身服务采样点数据配置
    monitor: 'codelab-monitor'
scrape_configs:
  # job名称会增加到拉取到的所有采样点上，同时还有一个instance目标服务的host：port标签也会增加到采样点上
  - job_name: 'prometheus'
    # 覆盖global的采样点，拉取时间间隔5s
    scrape_interval: 5s
    static_configs:
      - targets: ['localhost:9090']

2.2 登录配置

• 登录 http://127.0.0.1:3000
• 修改密码 默认 admin admin
• 配置 DataSource 127.0.0.1:9090
• 添加面板

app(metrics)–data–> (?) + prometheus + grafana
