Env Variables

Karafka's behaviour can be altered with the following environment variables:

Name	Description
KARAFKA_ROOT_DIR	Root dir of the Karafka application. Defaults to the directory in which Bundler was executed (BUNDLE_GEMFILE)
KARAFKA_ENV	Karafka app expected environment. If not defined, autodetected based on RAILS_ENV, RACK_ENV with a fallback to development.
KARAFKA_BOOT_FILE	Location of Karafka boot file (karafka.rb) or false. Defaults to karafka.rb in the project root directory. May be set to false in case you want to fully control Karafka boot process.
KARAFKA_REQUIRE_RAILS	Determines if Rails should be required when present in the Gemfile. If set to false, Karafka can run without Rails even if both are in the same Gemfile.
