My docker container isn't starting on localhos

问题:

I'm following Digital Ocean's tutorial on how to start a nginx docker container (Currently on Step 4). Currently this is their output:

$ docker run --name docker-nginx -p 80:80 -d nginx
d3ccb73a91985651ec61231bca9f9c716f0dec807e354a29eeef2144f883a01c

$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                         NAMES
b91f3ce26553        nginx               "nginx -g 'daemon off"   About a minute ago   Up About a minute   0.0.0.0:80->80/tcp, 443/tcp   docker-nginx

But when I run it, this is my output (noticed the different IP of the container):

C:\>docker run --name docker-nginx -p 80:80 -d nginx
d3ccb73a91985651ec61231bca9f9c716f0dec807e354a29eeef2144f883a01c

C:\>docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                           NAMES
d3ccb73a9198        nginx               "nginx -g 'daemon off"   14 hours ago        Up 2 seconds        10.0.75.2:80->80/tcp, 443/tcp   docker-nginx

Why does this happen? And how can I get the same results as Digital Ocean's? (Getting the server to start on localhost)

Edit: I'm using Docker for windows (recently released) which apparently runs native using Hyper-V. My output for docker-machine ls is this:

C:\>docker-machine ls
NAME   ACTIVE   DRIVER   STATE   URL   SWARM   DOCKER   ERRORS

Since this a Windows machine, I assume that you're using Docker Toolbox Docker for Windows. 10.0.75.2 is the IP of the boot2docker virtual machine.

If you are using Windows or Mac OS, you will need some form of virtualization in order to run Docker. The IP you just saw is the IP of that lightweight virtual machine.

Use a Linux distribution! Also you can enable Expose container ports on localhost in Docker For Windows Settings:

Despite you created the containers in your local machine. These are actually running on a different machine (a virtual machine)

First, check what is the IP of your docker machine (the virtual machine)

$docker-machine ls
NAME      ACTIVE   DRIVER       STATE     URL                         SWARM
default   *        virtualbox   Running   tcp://192.168.99.100  

Then run curl command (or open a browser) to view the default web site on your nginx web server inside the container

curl http://192.168.99.100:80
