本文介绍了如何在使用Docker Toolbox环境下，将Tomcat容器应用映射到Windows主机上，并可通过局域网访问。通过在Oracle VirtualBox Manager中设置端口转发规则实现这一目的。

I am running docker on my windows system using docker toolbox. I ran tomcat container using command docker run -it --rm -p 8888:8080 tomcat:8.0. As per documentation I should be able to access tomcat using http://localhost:8888, but this is not working.

Rather, I can access the tomcat app using docker-machine ip which is http://192.168.99.100:8888.

But this is not what I need. I need to access the tomcat container app from outside my system itself, through the network. So, how do I map tomcat application to my windows host system ?

While googling around, I could see an option of port-forwarding for boot2docker vm. But, again I am not using boot2docker. I am using docker toolbox.

解决方案

Finally, I was able to find where to add the port-forwarding rule. Open the oracle VirtualBox Manager. Go to Settings-->Network --> Port Forwarding..

Here 1 rule is already available for ssh.

So I added another rule for this with below configurations:

HostIP:HostPort=> 127.0.0.1:9999

GuestIP:GuestPort=> :8888

So now if I invoke http://localhost:9999 , it is forwarded to => docker-machine:8888 and from there it is forwarded to => tomcatVM:8080.
