在ip
B类范围内
但我的本地主机在
C范围内

那么我如何从192.168连接到mysql到172.18呢? 我在stackoverflow中找不到相同的问题

我在谷歌上搜索了两天,有人说:嘿,你们应该使用网关和路由器

但我如何将172映射到192?它们都是私有IP,而不是公共IP


我知道这个问题很愚蠢,这是一个计算机网络问题,但请帮我解决这个问题。

您应该尝试使用localhost:3300连接到mysql容器

首先,在本地计算机上安装docker引擎时,默认情况下docker在localhost(ie)127.0.0.1 ipaddress中运行

根据您的docker编写文件

ports:
- "3300:3306"
3306端口暴露在容器内,与主机3300端口相连

接下来,您提到了容器的IP地址

        "Config": [
            {
                "Subnet": "172.18.0.0/16",
                "Gateway": "172.18.0.1"
            }
        ]

这是您创建的网络,名称为onlinecode net“。此网络由docker引擎创建,该引擎在内部用于连接主机中未公开的容器。

docker for Windows中的网络功能:。建议的方法是
端口发布到主机。您的docker引擎位于windows 10主机或virtualbox中。@Prem它是windows内核上的docker版本:4.9.93-linuxkit-aufs操作系统:docker for windows OSType:linux体系结构:x86_64 CPU:2总内存:1。934GiB@PremWindows 10 pro虚拟机监控程序。。不是VBox那么您应该尝试使用localhost:3300,这可能会起作用,因为据我所知,您正在尝试从主机中运行的应用程序连接到docker容器(mysql容器)。因为这是一个常见的混淆点:
docker run-p
端口只能通过127.0.0.1或
localhost
从浏览器或直接在主机系统上运行的其他工具访问。其他容器认为“localhost”意味着“我的私有容器名称空间”,这样就无法访问其他容器。
