The document outlines how to set up a development environment using container technology, specifically Docker. It contrasts traditional and virtualized development environments, highlighting the benefits of using containers for isolated and easily shareable setups. The workshop aims to demonstrate running multi-tier applications with Ruby on Rails and managing dependencies efficiently.

3. What you are going to learn today
• Overview of how to setup a development
environment
• Some background about virtualization
• How to run a development environment using
Docker containers
• How to add new libraries and make changes in
your application code

4. What’s a development environment?
• Editor / IDE
• Source control
• Runtime
• Dependencies

5. Traditional development environment
• Runtime and dependencies installed in your
OS
• Using system packages (apt-get) or similar
(homebrew)
• Tailored for your machine
• Runtime versioning at best using rbenv,
python virtualenv

6. Virtualized development environment
• Isolated part of your main computer which thinks it’s a
computer on its own
• It uses memory and CPU resources like a real computer
• It runs an operating system and applications
• Messing with it will not pollute the host OS
What’s a Virtual Machine?
What’s a Container?
• Lightweight Virtualization method
• Service oriented
Like a Virtual Machine plus:

7. Virtualized development environment
Runtimes and dependencies
running inside a Virtual
Machine or a container

8. Traditional vs Virtualized
Traditional Virtualized
OS independent No Mostly
Shareable No Yes
Reproducible Hard Easy
Upgradeable Hard (patch) Easy (replace)

11. Summary
• Run multi-tier applications, i.e database +
NodeJs
• Install dependencies, i.e rubygems, npm
• Run common tasks, i.e rake, gulp
• Share your environment with team members
With a Bitnami developer environment you can
