docker安装prometheus

1、下载进行

 docker pull prom/prometheus

2、维护配置信息

mkdir /opt/prometheus    
cd /opt/prometheus/
vim prometheus.yml

• 内容如下

global:
  scrape_interval:     60s
  evaluation_interval: 60s
 
scrape_configs:
  - job_name: prometheus
    static_configs:
      - targets: ['localhost:9090']
        labels:
          instance: prometheus
 

• [再加个data文件夹用于挂载prometheus的数据]

mkdir /opt/prometheus/data 

• 将挂载目录权限设置为777 [防止run时候提示data没有权限创建文件目录啥的]

    chmod 777 -R /opt/prometheus

3、启动Docker

docker run  -d \
  -p 9090:9090 \
  -v /opt/prometheus/prometheus1.yml:/etc/prometheus/prometheus.yml \
  -v /opt/prometheus/data:/prometheus \
  prom/prometheus \
  --config.file=/etc/prometheus/prometheus.yml \
  --storage.tsdb.retention.time=100d

• storage.tsdb.retention.time=100d 【保留100天数据】

4、检查是否启动

• 访问地址： http://localhost:9090/graph
