An example Diego Docker container gotcha

How to get a Permission denied from Bundler using Diego

• Install Lattice
• Make sure it's running: ltc list should say "No apps to display."
• Start watching logs in one terminal: ltc logs task1
• In another: clone this repo and cd to the dir
• Push this task: curl -i -XPOST http://192.168.11.11:8888/v1/tasks -d@task-payload.json
• The exception should appear in the watched logs

This contrived example reflects a mistake I made in the real world: I bundled once in the Dockerfile and again in the script I wanted to run. A similar situation might occur if the /app dir was only accessible by root.
