如何基于Docker Swarm多机部署Hyperledger Fabric？

前言
最近在研究如何用Docker Swarm多机部署，也找了很多博客和教程，发现很多说的其实不是很清楚，所有，在踩了很多坑之后，我做一个搭建过程的记录，尽量写的详细一点。

本文准备部署一个6个组织，每个组织2个peer节点，其中5个组织维护5个排序节点的Hyperledger Fabric 区块链网络。
Docker Swarm来连通各个主机的节点

本项目开源地址 https://gitee.com/ccccczy77/fabric_docker_swarm

准备6台阿里云的服务器，推荐购买按量付费的实例就可以，不用了及时释放掉！（樂樂阿里云打钱！！！本来想用腾讯云的，结果我在腾讯云没有找到按量付费的服务器）

docker
docker-compose
hyperledger fabric的镜像

这一步直接参考fabric的官方文档就可以了。如果能搜到这篇博客的话，这一步肯定已经安装完毕了，就不赘述了。
到这里前期准备就完事了。

初始化docker swarm

docker swarm init --advertise-addr 

生成一个其他host加入同一个网络的命令

docker swarm join-token manager

把上一步生成的命令放到这一条命令的开头，加上本机的ip
对其余的5台主机都操作一下这一步

 --advertise-addr 

在各个主机都查看一下有没有成功，
（路‍♂️话说这里其实我有点不太明白？为什么各个主机都以manager身份加入？docker swarm中的worker和这个有什么关系！有懂的大佬在教教我！）

docker node ls

接下来生成一个docker network，输入如下命令（这里的basic-network是网络名字，可以自定义哈~ ，不过要和后面指定的名字对应起来！）

docker network create --attachable --driver overlay basic-network

在这里我们配置节点启动文件，然后用docker-compose启动起来。
启动文件仓库里面有！仅供测试用哈。改配置文件实在太头疼了！

下面简答拿一个文件举个例子！

    networks:

下面说明几个网络需要注意的地方

这一块声明用外部网络，basic-network是我的网络的名字。

networks:
  basic-network:
    external: true
    name: basic-network

这里也要是basic-network，和上面对应

    networks:
      - basic-network

这一块的参数也是basic-network

      - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=basic-network

OK，到现在为止，好像所有的配置有关的东西都准备好了。接下来就把项目跑起来吧！

输入启动节点，在6个服务器都启动一下就行了,记得改文件名！

docker-compose -f  -f [] up -d

多机部署完毕啦，接下来可以进行一些通道链码的操作啦！
放一张查询成功的截图哈哈✌️✌️

有关多机搭建如何用sdk来进行操作，之后有时间我再尝试吧！
理论上好像只需要更新一下节点的ip就可以！后面再说！

okk，到此为止，就记录完毕啦！
