As environment variables can be set outside of the code, but can be read by the code, and don't have to be stored (committed to `git`) with the rest of the files, it's common to use them for configurations or **settings**.

You can also create an environment variable only for a **specific program invocation**, that is only available to that program, and only for its duration.

// on a bucket to the right bucket location, bucket to IP configuration
// is obtained from centralized etcd configuration service.
