Thanks for this.
Do I actually put in the YOUR_API_KEY in this file please?

Thanks

Wow, it's 2016 and your post still works exactly as described. Thanks!

This works pretty well! I changed the last section to

        91setup_datadog:
            command: "sh -c \"sed 's/api_key:.*/api_key: {{DATADOG_API_KEY}}/; s/\\# tags:.*/tags: {{ENVIRONMENT}}/' /etc/dd-agent/datadog.conf.example > /etc/dd-agent/datadog.conf\""
