一、Docker环境准备

本文基于Windows 10+Docker Desktop单机搭建集群，如需跨主机搭建，请自行搜索Swarm或Docker跨主机通讯相关内容。

1、安装Docker Desktop

Docker Desktop自带了Docker Compose，无需另外安装

1
2
# 验证一下
docker-compose --version

2、创建Docker网络

1
docker network create --driver bridge --subnet 172.18.0.0/16 taosnet

二、集群配置

1、创建数据文件夹和配置文件

1
2
3
/path/to/tdengine-docker/node{n}/logs
/path/to/tdengine-docker/node{n}/data
/path/to/tdengine-docker/node{n}/taos.cfg

2、编辑docker-compose.yml

fqdn                      taos-node1
serverPort                6030

node2:
firstEp                   taos-node1:6030
fqdn                      taos-node2

node3:
firstEp                   taos-node1:6030
fqdn                      taos-node3
serverPort                8030

4、启动集群组网

docker-compose up -d

# 在node1运行命令，让node2和node3加入集群

create dnode "taos-node2:7030";
create dnode "taos-node3:8030";

5、测试和访问
