基于Grafana和Prometheus的监视系统(2):环境配置

基于Grafana和Prometheus的监视系统(2):环境配置

0.基本说明

• 如何使用的组件的快速构建部署: docker镜像
• docker compose 方便容器的管理

1. 基本环境

• docker-ce [https://docs.docker.com/get-started/]
• docker componse [https://docs.docker.com/compose/install/]

2. 配置

• docker-compose.yml
  docker 镜像包括: prometheus, node-expoter, grafana, pushgateway, elasticsearch

docker-compose几个常用的命令

1. docker-compose stop 停止容器
2. docker-compose rm 移除容器
3. docker-compose up -d 后台启动
