+%title: Docker for Homo Troglodytes
+%author: Cody Hiar
+%date: 2019-01-15
+
+-> Docker for Homo Troglodytes <-
+=================================
+
+-------------------------------------------------
+
+# About Me
+
+* Graduated Computer Engineering at U of A
+* Now working remotely @ Blendable
+* Vim/Tmux Diehard, also cli in general
+* Interests: Python, Automation, DevOps, Linux
+
+# Where I be
+
+* www.codyhiar.com
+* www.github.com/thornycrackers
+
+# Past Presentations (available on GitHub)
+
+* Scraping with scrapy (YEGSEC)
+* Python Daemons (Edmonton.py)
+* Setting Django up on a VPS (Edmonton.py)
+
+-------------------------------------------------
+
+-> My Goals <-
+==============
+
+* Help build a mental model of Docker
+* Introduce Docker basics
+* Give some working examples for possibilites
+
+-> My Assumptions <-
+====================
+
+* You know what the concept of a VM is 
+* Little to no experience with Docker
+* You know _some_ linux
+* Take things with a grain of salt
+
+-------------------------------------------------
+
+-> What is Docker? <-
+====================
+
+```
+Docker == VM      // True
+Docker === VM     // False
+```
+
+^
+
+For all intents and purposes, you can use your
+mental model of a VM for Docker.  Some people will
+argue that there is a difference, usually their
+answers are ostentatious.
+
+-------------------------------------------------
+
+-> Handy Chart of Advantages <-
+===============================
+
+-> | Feature     | VM | Docker | <-
+-> | ----------- | -- | ------ | <-
+-> | Size        | **  |   **    | <-
+-> | Startup     | **  |   **    | <-
+-> | Integration | **  |   **    | <-
+
+-> Docker vs Vagrant <-
+-> MBs vs GBs <-
+-> Seconds vs Minutes <-
+
+-------------------------------------------------
+
+-> Installation <-
+==================

+- Linux:

+    /how-to-install-and-use-docker-on-ubuntu-16-04
+
+(Article includes CentOs 7, Debian 9, Ubuntu 18.04)
+
+-------------------------------------------------
+
+-> Pfffft Let's see it <-
+=========================
+
+example1.sh demo
+
+-------------------------------------------------
+
+-> What Happened? <-
+====================
+
+> "What goes up must come down" -Isaac Newton
+
+1. Docker looked for image (Downloads if needed)
+2. Docker spins up a container
+3. Container runs `echo Hello World`
+4. Docker spins down the container
+
+There will be no demo of a VM time equivalent
+
+-------------------------------------------------
+
+If the time difference between running a program
+on the machine and running a program in a
+container is negligible, then why don't we start
+running all commands inside of containers?
+
+-------------------------------------------------
+
+Answer: We don't understand Docker yet. But after
+this we will!
+
+-------------------------------------------------
+
+-> Let's dockerize a command <-
+===============================
+
+example2.sh demo
+
+-------------------------------------------------
+
+As you can see the run time of the program inside
+the container is blazingly fast. We can extend
+this concept of dockerizing command by building
+our own docker images that install all the
+dependancies necessary. 
+
+-------------------------------------------------
+
+-> Introducting Docker Files <-
+===============================
+
+Dockerfiles are a set of instructions that build a
+docker image which can then be ran locally, shared
+with others, and even extended to be included in
+other docker files.
