docker + fastdfs + springboot 踩坑记录

storage.conf 配置容器 tracker_server [容器]:22122

tracker_server=172.17.0.2:22122

百度一番：尝试将 tracker_server 改为 [宿主机]:22122

{
    "timestamp": "2021-10-09T07:56:09.902+0000",
    "status": 500,
    "error": "Internal Server Error",
    "message": "无法获取服务端连接资源：can't create connection to/172.17.0.1:23000",
    "path": "/upload/inputStream3"
}

？？？ 怎么是 172.17.0.1

查看docker网络

tracker把Docker容器的网关地址当成了storage的地址

尝试着容器内添加 iptables NAT规则

iptables -t nat -A POSTROUTING -p tcp -m tcp --dport 22122 -d 172.17.0.2 -j SNAT --to 192.168.153.103

无效 ，还是一样的报错

docker --net=host

sudo docker run -d --net=host  a:v1

storage.conf

tracker_server=192.168.153.103:22122

Springboot application.yml
