Image resize and upload using Iron functions and Joyent Manta

A Small demo iron-function which pulls some image from Joyent Manta OS, resizes it, and uploads it back to Manta OS.

Steps for usage :

1. build: fn build
2. run your local iron functions service docker run --rm -it --name functions -v ${PWD}/data:/app/data -v /var/run/docker.sock:/var/run/docker.sock -p 8080:8080 iron/functions
3. create an app fn apps create fn-demo
4. create a route fn routes create fn-demo /resize -i coze/fn-resizeimage-ruby (modify the image name as you see fit)
5. By default, fn tags the image with version. tag it with latest : docker tag coze/fn-resizeimage-ruby:0.0.1 coze/fn-resizeimage-ruby:latest
6. optional call from fn tool : echo '{"file": "The_Blue_Marble.jpg", "width":200, "height": 200}' | fn call fn-demo /resize
7. optional call via curl iron functions API curl -H "Content-Type: application/json" -X POST -d '{"file": "The_Blue_Marble.jpg", "width":100, "height": 100}' http://localhost:8080/r/fn-demo/resize
