为了开启docker远程端口真是难受
google了无数条,全差不多,因为有几种修改方式,所以都尝试过
这里修改点,哪里修改点,搞得回不去了
首先指明要修改的点
- 云服务器要开放docker的端口 可自定义端口
- /usr/lib/systemd/system/docker.service 文件 修改 ExecStart 处
- 读取 systemctl daemon-reload 重启 systemctl restart docker
查看docker状态
sudo systemctl status docker.service
sudo systemctl status docker.service
● docker.service - Docker Application Container Engine

英语水平太差不过看到了

然后我就 vim /etc/docker/daemon.json 查看发现有之前的配置没有删除
删除之后就好了
