IPFS 笔记 - 使用 Docker 搭建 IPFS 私链

准备

环境

安装好 go 环境
安装好 docker

swarm.key

swarm.key 用来做私链认证的密钥，最终要放在 /ipfs/data 目录下

go get github.com/Kubuxu/go-ipfs-swarm-key-gen
cd $GOPATH
go build
./ipfs-swarm-key-gen > swarm.key

查下生成的 swarm.key 内容：

/key/swarm/psk/1.0.0/
/base16/
5c99c0c67fe9d45d5b612afcb1f325d2826b2645ebb77c43e05e4b8472ccb3db

挂载目录

ipfs 的 export 和 data 目录挂载到主机上，这里做下准备，每个不同是私链节点的挂载目录不一样。

节点 node0 要挂载的主机目录：

/Users/lidiqing/Docker/ipfs/nodes/node0/export
/Users/lidiqing/Docker/ipfs/nodes/node0/data

节点 node1 要挂载的主机目录：

/Users/lidiqing/Docker/ipfs/nodes/node1/export
/Users/lidiqing/Docker/ipfs/nodes/node1/data

启动容器

创建节点

这里演示创建节点 node0 的流程，其他节点的创建流程一致，端口号和目录要修改。

把 swarm.key 放入到 /Users/lidiqing/Docker/ipfs/nodes/node0/data 目录下。

启动：

docker run 
    --name ipfs-node-0
    -v /Users/lidiqing/Docker/ipfs/nodes/node001/export:/export
    -v /Users/lidiqing/Docker/ipfs/nodes/node001/data:/data/ipfs
    -p 10000:4001
    -p 11000:5001
    -p 12000:8080
    -d ipfs/go-ipfs:latest

查看日志:

docker logs -f ipfs-node-0

Daemon is ready

打印出 Daemon is ready 说明 ipfs 已经启动了。Swarm is limited to private network of peers with the swarm key 可以看出使用了密钥，属于私链节点。

需要清理一下公链的引导节点。

docker exec ipfs-node-0 bootstrap rm —all

查看节点

按照上面的方式我们创建了多个节点，现在进入 node0 查看下情况。

打开节点的 shell：

docker exec -it ipfs-node-0 /bin/sh

查看已连接的所有 p2p 节点：
