本文主要讲解使用docker-compose快速部署TiDB集群，此方法官方已不建议在生产环境进行部署。
注：不建议使用此方法跨物理节点部署。
准备
- Docker （version >= 17.06.0）
- Docker Compose
- Git
- MySQL Client
获取 tidb-docker-compose
git clone https://github.com/pingcap/tidb-docker-compose.git
自定义集群
完整版见： tidb-docker-compose/docker-compose.yml
默认的情况下：3个PD，3个TiKV，1个TiDB和监控组件Pushgateway，Prometheus，Grafana以及TiDB-vision。
自定义集群需要修改docker-compose.yml文件
以下是修改成1个PD，1个TiKV，1个TiDB以及相应的监控组件

创建并启动集群
# 拉取镜像
docker-compose pull
# 启动集群
docker-compose up -d
执行成功后
示例中是启动了1个PD，1个TiKV，1个TiDB

停止集群
docker-compose stop
