-- WARNING, WARNING, WARNING: this is insane hack and should not be touched
-- This file is not templated by Liquid, because it is used by not blackbox integration tests (Search for TEST_NGINX_HTTP_CONFIG).
-- So it cannot be templated by liquid, to lift env variables and persist them in the configuration.
-- This is a workaround so we can store environment at the time of building the config into the config itself.
-- {% raw %} {{ ENV }} {% endraw %} is both valid Liquid template and Lua code.
-- In Lua it is a table with another empty table inside. In Liquid it prints variable ENV.
-- This ENV variable is defined in the main nginx.conf.liquid and injected when including this partial.
-- The content of the ENV variable is a Lua table, so when rendered it actually can run ipairs on it.
