NOTE: This was originally filed by @nikeee in elastic/elasticsearch-docker#183.

There is a convention on official docker images that environment variables that end in _FILE are read as a file and then assigned to a variable without the _FILE suffix. For example, setting the environment variable ELASTIC_PASSWORD_FILE to /run/secrets/secret-password will read the file /run/secrets/secret-password and assign its contents to the environment variable ELASTIC_PASSWORD. This is especially handy when using Docker secrets.
