Image server

Run

docker run --rm -v $(pwd):/src centurylink/golang-builder
docker-compose up

Description

Implement an HTTP server with the following routes:

• /generate/png/{width_px}/{height_px} - returns a black image/png that's of the specified width and height
• /generate/jpg/{width_px}/{height_px} - returns a black image/jpeg that's of the specified width and height
• /stats - returns application/json with the number of images generated since the server was started and the average width and height of those images.

For the /stats route, the json should look like this:

{
  "num_images": 1,
  "average_width_px": 123,
  "average_height_px": 456
}
