The COPY and ADD directives make it easy to add configuration files or download archives to a container image. While we could install applications into a container using only those directives, it would be difficult and complex. Making matters worse, Docker provides no INSTALL directive. Instead, Docker provides a more general mechanism.
In this tutorial, we'll:
- Introduce the
RUNdirective and how to run commands during adocker build - Use package managers to install applications
- Describe best practices for installing software in images
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug.

Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
Lets go ahead and get started shall we?
