推荐答案

命名容器不会更改您的主机文件或DNS，并且取决于您运行容器的方式，它可能无法像Docker一样通过标准端口进行访问端口翻译.

Naming the container doesn't alter your hosts file or DNS, and depending on how you ran the container it may not be accessible via the standard port as Docker does port translation.

运行 docker inspect redis 并检查端口输出，它将告诉您可访问哪个端口以及IP.但是请注意，这只能通过该主机上的该IP进行连接.要从主机之外访问它，您将需要使用上述命令中的端口和主机的IP地址.前提是您的本地防火墙规则允许这样做，但这不在本网站的讨论范围之内.

Run docker inspect redis and examine the ports output, it will tell you what port it is accessible on as well as the IP. Note, however, that this will only be connectable over that IP from that host. To access it from off of the host you will need to use the port from the above command and the host's IP address. That assumes your local firewall rules allow it, which are beyond the scope of this site.
