### Generic Dockerfile demonstrating good practices


### Imports

# Bad-ish, we do not need Ubuntu for this, nor do we want latest if we are using in a build system, predictable is better
FROM ubuntu:latest

# Better, using a small image since our app has no dependency on Ubuntu
FROM alpine:3.3

# Source arguments from Ansible
# These are passed into the module as $1 with a key=value format

# Note that variables that are unused in the module are silently ignored
source $1

# Helper function to fail the module with the specified error
# This can accept $@ in printf for the full error
