Add port mappings using Docker in Mac

Using Docker in Mac is actually using Boot2docker to start a Linux virtual machine "BOOT2DOCKER-VM"first through VirtualBox, so that after startup, Starting container from Docker, even if you add a port mapping, the host is inaccessible because this port mapping is the port that maps VirtualBox-initiated virtual machines to container.

At this point you need to add a route to the virtual machine that VirtualBox started, for example, you want to add Port 3306:

Terminal in the first

?VBoxManage modifyvm "boot2docker-vm" --natpf1 "tcp-port3306,tcp,,3306,,3306"

and then

boot2docker start

Then how do you play it?

For example:

docker run -p 3306:3306 -d mysql /usr/bin/mysqld_safe

Have fun!
