本文档介绍如何在单机上通过 Docker Compose 快速一键部署一套 TiDB 测试集群。Docker Compose 可以通过一个 YAML 文件定义多个容器的应用服务，然后一键启动或停止。
确保你的机器上已安装：
- Docker（17.06.0 及以上版本）
- Docker Compose
- Git
1.1、下载tidb-docker-compose
[root@docker35 ~]# git clone https://github.com/pingcap/tidb-docker-compose.git

1.2、创建并启动集群
创建并启动集群，获取最新 Docker 镜像：
cd tidb-docker-compose && docker-compose pull && docker-compose up -d
执行过程：
[root@docker35 ~]# cd tidb-docker-compose/
[root@docker35 tidb-docker-compose]# ll

二、访问集群
2.1、访问TiDB
[root@docker35 tidb-docker-compose]# mysql -h 127.0.0.1 -P 4000 -u root

2.2、访问集群 Grafana 监控
访问集群 Grafana 监控页面：http://localhost:3000 默认用户名和密码均为 admin。如下内容都可以监控到：
例如：
2.3、集群数据可视化
集群数据可视化（https://github.com/pingcap/tidb-vision）：http://localhost:8010
如果启用了 tidb-vision，可以通过 http://localhost:8010 查看。
2.4、访问Spark Web UI
http://192.168.66.35:8080/
三、自定义集群
在完成快速部署后，以下组件已默认部署：3 个 PD，3 个 TiKV，1 个 TiDB 和监控组件 Prometheus，Pushgateway，Grafana 以及 tidb-vision。
如果想自定义集群，可以直接修改 docker-compose.yml，但是手动修改比较繁琐而且容易出错，强烈建议使用 Helm 模板引擎生成 docker-compose.yml 文件。
安装 Helm
curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get | bash
brew install kubernetes-helm
下载 tidb-docker-compose
自定义集群
修改 values.yaml 里面的配置，例如集群规模，TiDB 镜像版本等。
PD，TiKV，TiDB 和 tidb-vision 支持从 GitHub 源码或本地文件构建 Docker 镜像，供开发测试使用。
- 如果希望从本地已编译好的 binary 文件构建 PD，TiKV 或 TiDB 镜像，需要将其
image字段留空，并将已编译好的 binary 拷贝到对应的pd/bin/pd-server，tikv/bin/tikv-server，tidb/bin/tidb-server。 - 如果希望从本地构建 tidb-vision 镜像，需要将其
image字段留空，并将 tidb-vision 项目拷贝到tidb-vision/tidb-vision。
生成 docker-compose.yml 文件
使用生成的 docker-compose.yml 创建并启动集群
docker-compose -f generated-docker-compose.yml pull
访问集群
四、访问 Spark shell 并加载 TiSpark
向 TiDB 集群中插入一些样本数据：
docker-compose exec tispark-master bash &&
cd /opt/spark/data/tispark-sample-data &&
mysql -h tidb -P 4000 -u root < dss.ddl
当样本数据加载到 TiDB 集群之后，可以使用 docker-compose exec tispark-master /opt/spark/bin/spark-shell 来访问 Spark shell。
docker-compose exec tispark-master /opt/spark/bin/spark-shell
...
Spark context available as 'sc' (master = local[*], app id = local-1527045927617).
Spark session available as 'spark'.

docker-compose exec tispark-master /opt/spark/bin/pyspark &&
docker-compose exec tispark-master /opt/spark/bin/sparkR
