Docker Port 2375 Windows 8.1 And Ubuntu

This is merely to ease development effort if you are doing it on your own Mac Book.

Docker is a relatively new breed of virtualization technologies known as Containers.

A commonly used analogy for Docker is to compare it to actual real-life containers or lego bricks: it provides a fundamental unit, and with it a way for an application to be portable and moveable, regardless of hardware.

Its the docker binary that well be interfacing with whenever we open a terminal and type docker pull or docker run.

Keeping with the containerlego brick analogy, theyre our blueprints for actually building a real instance of them.

An image can be an OS like Ubuntu, but it can also be an Ubuntu with your web application and all its necessary packages installed.

Docker (the company) offers a public Docker Registry called the Docker Hub which well use in this tutorial, but they offer the whole system open-source for people to run on their own servers and store images privately.

This involves using Boot2Docker that has a built-in Linux Machine.

The boot2docker tool makes this about as easy as it can be by provisioning a Tiny Core Linux virtual machine running the Docker daemon and installing a Mac version of the Docker client which will communicate with that daemon.

The challenge with this approach, unlike, the boot2docker approach is that all Docker commands need to be handled in the by logging into the Linux VM.

This post gets into how to get native-ish experience on your Mac but youre running a Docker host that doesnt work with boot2docker specifically the Docker host is running on Ubuntu Trusty host running as a VMWare Fusion Guest OS.

There are prerequisites that need to be taken care of if you are running something other than Ubuntu Trusty 14.04.

The install primarily involves the following command (details in the link above).

The trick is to know that the Docker client does all of its interaction with the Docker daemon through a RESTful API.

So we need to open up a communication channel and making the API to the Docker host in the virtual machine accessible to Mac OS X.

This involves configuring the VMShare Fusion NAT Settings for the Ubuntu Trusty Guest OS.

In addition we need to get the IP Address of the Docker engine or Docker Host running in Ubuntu.

In my case it was 172.17.42.1.

This is important to understand.

We are NOT looking for the IP Address of the Guest OS or the eth0 of the Guest OS but the Docker Host IP Address.

I have two Guest OSes installed Windows 8.1 and Ubuntu Trusty.

When I run ifconfig command I see a number of networking interfaces and two that are labeled vmnet1 and vmnet8.

Pick the one that is on the same subnet, here is what I had.

Note in the above example the IP Address used for the VMs IP Address is actually the address of the docker0 interface provided in the ifconfig command when run in Ubuntu.

Assuming you have installed Docker on the Ubuntu Guest OS and Docker client on Mac OS X using brew minutes apart you would have the latest version and they would be the same.
