Abstract

Let’s take a look at two popular orchestration and configuration management frameworks. We’ll compare and contrast them as we work through some examples learning how to deploy a simple application stack that will require managing users, installing packages, writing templates, and controlling services.

Outline

Outline

  1. Systems Engineering Challenges – Introduction to the problem space
    • Inventory – What do we have and what’s it doing?
    • Configuration – What is it running and how is it running it?
    • Deployment – What do we need to change to get it to run new stuff?
  2. Solutions
    • Historical view
      • Corporate offerings
      • OpenSource / Free Software
        • CFEngine
        • Puppet
        • Chef
  3. Ways to skin a cat – Introduction to Fabric, SaltStack, and Ansible
    • Communications channels – Message Queueing vs SSH
    • Execution Models
      • Agent vs Agent-less
      • Push vs Pull
    • Imperative vs Declarative
    • High level DevOps concepts
      • Infrastructure as code
      • Deterministic Builds/Deployments
      • Eventual Convergence and Anomaly Detection
      • Whiskey Tango Foxtrot is “Idempotent”
  4. Getting going
    • Fabric
      • Requirements
      • Installation
    • SaltStack
      • Requirements
      • Installation
      • Configuration
    • Ansible
      • Requirements
      • Installation
      • Configuration
    • Our first executions
      • remote command execution
    • Scripts/Recipies/States/Playbooks
      • Adding users
      • Installing software
      • distributing files
  5. Your Challenge (should you accept it)
    • Deploy a web application
      • python
        • setuptools
        • pip
      • web server - nginx
      • our application
        • pyramid and dependencies
        • application code
    • Rinse and repeat (with a different tool/framework)
  6. Open discussion
    • Observations
    • Likes/dislikes

Requirements

Everyone will need to bring a computer with an ssh client and have very basic understanding of how to operate in a Unix environment.

    To complete the review, we need draft slides and link to a self-recorded video explaining what this workshop is about and why the audience should attend it. Also, is there link to a GitHub repo for this workshop? Please share this information, latest by Wednesday, 22 Feb.

      @zainbbawa, regarding github, I have not yet put together the exact curriculum for this class. I’ve taught both subsets and supersets of this material in the past: https://2015.eurobsdcon.org/tutorials/ (see DevOps’ing on BSD) and https://us.pycon.org/2015/schedule/presentation/331/ as well as https://2016.eurobsdcon.org/tutorials/ (see Novice to Advanced Salt on BSD). I’ll put the course material specifically for this conference and put it on github after I get confirmation that the session have been approved/selected and well in advance of the event. Here is an example from a previous session: https://github.com/DevOpsing/workshop00

      For workshops I tend not to produce slides as everthing is interactive and hands-on. In the repository I will include step-by-step instructions that do not break down easily into slides but the totality of the information will be available.

      As for the video, my apologies but I have not had time to put one together. Is this for potential students to see or simply for the selection process?
