## Intro to docker

This is the code for my intro to docker class. These are the materials for an in-person class, and are **not for self-directed learning**. This is still being put together. Please clone the repo on the day of the class for the latest materials.

## Getting Started

We first need to setup our machines. Click the link for your OS. 

* [Windows 10](https://gist.github.com/TerribleDev/dd424d3d090bcf5634dcf8417411a081)
* [Windows 7](https://gist.github.com/TerribleDev/721fde498ae7e2e17c5c44a9d8e07412)
* [Windows 8, 8.1, Server 2012, Server 2012 R2](https://gist.github.com/TerribleDev/ad0d19734cbf0b5717a2d4e6fef7f011)
* [Ubuntu 14.04](https://gist.github.com/TerribleDev/3e0a8bab68b83fe5ef896a3bf16a85ce)



## macOS Yosemite 10.10.3 or above

if you are on macOS you can `brew cask install docker-toolbox` or you can download the docker [toolbox here](https://download.docker.com/mac/stable/Docker.dmg). You will then need to install [dotnet core](https://www.microsoft.com/net/core#macos). 

I don't have a mac so I couldn't test this, but this script might work so long as you have ruby installed:


```bash

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew tap caskroom/cask
brew cask install docker-toolbox
brew update
brew install openssl
mkdir -p /usr/local/lib
ln -s /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib /usr/local/lib/
ln -s /usr/local/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/
brew cask install dotnet
brew install node
npm install -g npm
npm install -g yeoman generator-docker generator-dotnet

```

## What you will need

if you prefer to not use the scripts I have made you will need the following installed.

* dotnet core 
* docker-toolbox
* nodejs
* npm
* yeoman
* generator-docker (npm module)
* generator-dotnet (npm module)

## Notes about Windows 7, 8, 8.1, server 2012

Since you are on older verisons of windows you will run the docker kernel as a VM in a [hypervisor](https://en.wikipedia.org/wiki/Hypervisor). Your hypervisors are listed below.

* Win 7 - `virtualbox`
* Win 8, 8.1, 2012 - `hyperv`


We need to create a machine by doing the following. Please note that you must replace MyHypervisor with the hypervisor listed above


```powershell
# powershell
docker-machine create mydock -d MyHypervisor
```

Now when we work with docker we need to first configure our shell to tell docker to use this machine (once per shell instance)

```powershell
# powershell
docker-machine env mydock | invoke-expression
```

You will then need to `docker-machine ls` and take note of your docker machine's IP address. When we launch websites in docker instead of browsing on localhost you will browse to your docker machine's IP address.
