问题:

执行docker run后出现以下报错

(HTTP code 500) server error - Ports are not available: listen tcp 0.0.0.0:11211: bind: An attempt was made to access a socket in a way forbidden by its access permissions.

原因是使用了hyper-V的保留端口

# 查看hyper-v启动后的保留端口范围
netsh interface ipv4 show excludedportrange protocol=tcp

协议 tcp 端口排除范围
 
开始端口    结束端口
----------    --------
      1026        1125

# 通过这个可以查看被占用的项目端口是否在这个范围内

解决办法:

管理员权限运行cmd后按以下步骤输入命令并运行docker

1.停止Windows NAT 驱动程序
net stop winnat

2.启动容器
docker start ...

3.开启Windows NAT 驱动程序

net start winnat
