Getting Started, Part 1: Orientation and Setup |
{% include content/docker_elevator_pitch.md %}
This tutorial will create a simple application that runs in a cluster, so you get a sense of how to build distributed applications with the Docker platform. We will achieve this in the following steps:
- Get set up and oriented, on this page.
- Create a "Hello World" application that identifies its environment
- Hook up a visitor counter
- Scale our app as if it were very high traffic, by setting up a cluster in production
The application itself is very simple so that you are not too distracted by what the code is doing. After all, the value of Docker is in how it can build, ship, and run applications; it's totally agnostic as to what your application actually does.
Before we get started, make sure your system has the latest version of Docker installed.
Install Docker{: class="button darkblue-btn"}
Note: If you're in Linux, you'll want to install Docker Toolbox so you get Docker Compose.
If you understand that container images package application code and their dependencies all together in a portable deliverable, and your environment has Docker installed, let's move on!
