1. 下载源码

cd /root
git clone https://github.com/filecoin-project/lotus.git
cd lotus/

2. 拷贝Dockerfile到源码根目录

cp tools/dockers/docker-examples/basic-miner-busybox/Dockerfile .

3. 拷贝时区文件

cp /etc/localtime .

4. 修改Dockerfile

• 增加了时区
• 修改了默认entrypint命令
• 修改默认用户

默认会安装lotus、lotus-storage-minier、lotus-seal-work，默认跑lotus-seal-worker，可以覆盖entrypoint跑lotus和lotus-storage-minier命令

5. 构建镜像

docker build -t lotus-test:v0.28-work .
 

构建好后再推送到镜像仓库

6. 运行 lotus-seal-work

docker run  --name lotus-work  -d -e WORKER_PATH=/data/lotusworker -e STORAGE_API_INFO=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJBbGxvdyI6WyJyZWFkIiwid3JpdGUiLCJzaWduIiwiYWRtaW4iXX0.gyhqIDRToC29zhIQZDbuqht-GcGJ6HwsKQM7Hu_6HhF:/ip4/192.168.0.1/tcp/2345/http  -p 1234:1234 -v /data/lotuswork/lotusworker:/data/lotusworker -v  /data/filecoin-proof-parameters-v20:/var/tmp/filecoin-proof-parameters    lotus-test:v0.28-work  

注：

1. 需要指定WORKER_PATH并挂载到本地目录至少准备1T的存储空间
2. STORAGE_API_INFO指定存储矿工TOKEN:STORAGE_NODE_MULTIADDR
