Datadog API in Docker Containers Needs a Hostname

Lately I’ve had the good fortune of working on an app migration effort with a heavy focus on containerization, specifically a couple of batch processes which run daily. Formerly, these processes were run by an enterprise scheduling system which handled alerting. After deciding to rewrite the batch processing functions and containerize them, that left me short alerting. I decided to implement a new alerting solution using Datadog, since we’re already using it to gather metrics for the main application.
