在Docker for Mac中将容器映射到除localhost外的主机名 [英] Map container to hostname other than localhost in Docker for Mac

问题描述

我正在创建一个Nginx容器，我想在 http://api 上进行本地访问.使用Docker Machine，我假设运行 docker-machine create default 和 docker-machine ip default 来接收IP并将我的主机文件编辑为如下内容:

#docker-machine ip default->192.168.99.100
192.168.99.100 API

应将对 api \ 的请求映射到Docker Machine IP并提供我的内容.

两件事使我感到困惑:

1. 我通过Mac App启动Docker，可以创建Nginx容器并访问 http://localhost 上的内容.但是，运行 docker-machine ls 不会返回任何机器.这令人困惑，因为我认为Docker必须在VM上运行.
2. 从头开始并启动Docker Machine，然后旋转容器似乎没有任何效果.换句话说，我仍然可以访问 http://localhost 上的内容，但不能访问 http://api

我不想在 http://localhost 上访问我的容器，而是想在 http://api 上访问它.我该怎么做?

我正在为Mac 17.12和Docker Machine 0.14使用Docker.

解决方案

根据您的问题:

我想访问的不是

第二件事::编辑主机 etc/hosts 文件并添加

  api 192.168.43.8 [您的IP] 

这就是您在浏览器中看到的方式.

I am creating an Nginx container that I would like to access locally at http://api. Using Docker Machine, I assumed running docker-machine create default and docker-machine ip default to receive the IP and editing my hosts file to something like this:

# docker-machine ip default --> 192.168.99.100
192.168.99.100 api

should map requests to api\ to the Docker Machine IP and serve my content.

Two things are confusing me:

1. I launch Docker through the Mac App and can create Nginx containers and access content at http://localhost. However, running docker-machine ls returns no machines. This is confusing because I thought Docker had to run on a VM.
2. Starting from scratch and starting Docker Machine, then spinning up containers seems to have no effect. In other words, I still can access content at http://localhost but not http://api

Instead of accessing my container at http://localhost I want to access it at http://api. How do I do this?

I'm using Docker for Mac 17.12 and Docker Machine 0.14.

解决方案

On the base of your this question:

Instead of accessing my container at http://localhost I want to access it at http://api. How do I do this?

Your docker run command:

docker run -it --rm --name test --add-host api:192.168.43.8 -p 80:80 apachehttpd

1st Thing: The --add-host flag add value to /etc/hosts in your container /etc/hosts so http://api will also response inside the container if ping inside that container. This is how will ping response inside container

2nd Thing: Edit your host etc/hosts file and add

api 192.168.43.8 [your ip]

This is how you can see in Browser.
