直接拉取镜像，创建容器并运行容器一把梭哈：
docker run -d --restart=always \
--privileged=true \
--net=host \
--name=fastdfs \
-e IP=192.168.149.128 \
-e WEB_PORT=80 \
-v ${HOME}/fastdfs:/var/local/fdfs registry.cn-beijing.aliyuncs.com/tianzuo/fastdfs
其中-v ${HOME}/fastdfs:/var/local/fdfs是指：
将${HOME}/fastdfs这个目录挂载到容器里的/var/local/fdfs这个目录里。
所以上传的文件将被持久化到${HOME}/fastdfs/storage/data里，
IP 后面是自己的服务器公网ip或者虚拟机ip，-e WEB_PORT=80 指定nginx端口
访问容器：
docker exec -it fastdfs /bin/bash
追加文本信息到index.html文件中
echo "Hello FastDFS!">>index.html
上传此文件？
fdfs_test /etc/fdfs/client.conf upload index.html
