Presentation at the SoCal Node.js Meetup

(Click on the image above to watch the video of the talk)

Description

Docker is everywhere but nobody knows what to do with it.
The goal of this session is to provide you with everything you need to get started.

We'll discuss and demonstrate the following:

• What is Docker?
• What does docker solve?
• How to use it for development work flow?
• How to use it for deployment/production work flow?

Let's skip the boring concepts - we will look at a real-world Node.js application that uses multiple Docker containers.

Slides

03:35 What is Docker?

• 04:35 Demo: Running a project with 7 containers on my laptop

• 08:46 Value for Ops
• 10:14 Terminology
• 10:37 Container Ecosystem

11:18 What does docker solve?

16:57 How to use it for development work flow?

• 17:17 Multiple Containers for running a projects and a Log Server
• 18:20 Registration and Discovery with Consul and registrator
• 18:50 Demo: Android/Cordova development using Docker

19:13 How to use it for deployment/production work flow?

• 19:17 What components do you need for running Docker in Production? Scheduler, Registration, Discovery
• 19:26 Scheduler
• 20:05 Discovery
• 20:17 Work flow tools: Deis, Flynn, Paz, Mesos + Marathon
