5. TileMill 2 Installation and Configuration

Install Tilemill2 and provide Tile Service Server in Docker (Vector Tiles)

Install properties: sudo apt-get install python-software-properties
Add nodejs repository: echo 'Yes' | sudo apt-add-repository ppa:chris-lea/node.js sudo
Update repository list: apt-get update -y sudo
Install nodejs: apt-get install -y nodejs build-essential

Clone Tilemill2 github repository: git clone https://github.com/mapbox/tm2.git
Navigate in cloned Tilemill2 folder: cd tm2
Install TIlemill2: npm install
Start Tilemill2 instance: node index.js

Open browser and type: localhost:3000 in your address bar to check if it's working. Instead of localhost, you have to use your Server IP.
Change address to: localhost:3000/unauthorize
Connect the instance with your mapbox account (log in)

Download osm-birght.tm2 dataset: https://github.com/mapbox/osm-bright.tm2 or get it via git clone https://github.com/mapbox/osm-bright.tm2.git
Click on your Profile Pic (upper left corner) and click on "browse"
Navigate to the folder, where you've saved the osm-bright.tm2 stuff and click open
Osm-bright will be added to your Tilemill2 Instance
Save it (the project is now stored in the Tilemill2 app and can be accessed via "Profile -> clicking on "osm-bright")
Start styling ;)

By panning and zooming withing Tilemill it could be possible that some svgs are missing (check the Terminal instance, where you've typed node index.js.
Look for errors, where files are missing and add them via wget. For example: wget https://raw.githubusercontent.com/mapbox/maki/mb-pages/src/car-12.svg
Be sure that the icons are saved in the right folder (/tm2/osm-bright.tm2/icons (osm-bright folder (where you've cloned the osm-bright.tm2 stuff))
