// Untested in 3D, but "theoretically" this should

Deploying Deis on AWS

These instructions will get you up and running with Deis and CoreOS in a AWS VPC. There already exists a CloudFormation script to get up and running in AWS. But if you want to get down and dirty, this document will help walk you through the steps.

I tried to build these instructions for both the AWS web console and equivilent AWS CLI. If you find errors, please feel free to comment so I can update them. You can also find me in the #deis IRC channel on Freenode if you have questions.

AWS

Since we will be running CoreOS and Deis inside a VPC we need some AWS setup first. We need a single subnet VPC, some security groups, and instances of CoreOS.

 An Albers Equal Area Conic projection in javascript, for protovis.

 For centering the contiguous states of the USA in a 800x400 div, I used:

 var scale = pv.Geo.scale(albers(23, -96, 29.5, 45.5))
                .range({ x: -365, y: -375 }, { x: 1200, y: 1200 });

Building GDAL 1.9.x with ESRI FileGDB support on OS X Lion

• Download the SDK from ESRI's website http://resources.arcgis.com/content/geodatabases/10.0/file-gdb-api
• Extract the SDK, and put the contents of the directory in a known location, I used ~/local/filegdb. Here's an example path to one of the files: ~/local/filegdb/lib/libFileGDBAPI.dylib
• I use ~/local/filegdb so it can stay isolated in it's own place. You can put it anywhere, but the next few steps might be different.
• Go into the directory containing the FileGDB SDK, e.g. ~/local/filegdb
• ESRI built these dylib's using @rpath's, so to avoid needing to mess with DYLD_LIBRARY_PATH, I updated the @rpath's using install_name_tool. There might be a more elegant way to handle this. If so, comments are welcome!
• Here are the commands I used to patch the dylibs, this is not required if you want to use DYLD_LIBRARY_PATH yourself:
