树莓派上做的ddns要自启动

sudo  vim /usr/lib/systemd/system/myddns.service  

#这里myservice.service可以定义为自己想要取的名字。

使配置文件生效
sudo systemctl daemon-reload     #重载服务列表
sudo systemctl enable myddns.service  #设置开机自启动
sudo systemctl start  myddns.service    #开启服务
sudo systemctl  status  myddns.service   #查看服务是否正常运行
 
或者重启查看能否自启动。
reboot

systemctl enable shadowsocks

最后要检查一下端口(12000)是否开放 要不然没办法使用代理

[Standard_init_linux.go:190: exec user process caused “exec format error]

You have to run the docker image that was built for a particular Architecture on a docker node that is running that same Architecture.

Take docker out of the picture for a moment. You can’t run a Linux application compiled and built on a Linux ARM machine and run it on a Linux amd64 machine. You can’t run a Linux application compiled and built on a Linux Power machine on a Linux amd64 machine.

I answered this same issue/question in this another post.
Take a look -> How much does Docker virtualize? 367
