Environment settings for Game On!

The game's environment is configured in a few different ways:

  • When running locally, gameon.env (or gameon.${DOCKER_MACHINE_NAME}.env) contains environment variables provided to the core game containers at startup.

  • Some of these environment variables might instead come from etcd or other config provider if that is present

There are also two different toggles that change game behavior:

  • GAMEON_MODE -- the value can be either development or production

    • development is used to enable experimental features, or to allow behaviors that facilitate testing

    • production is used in the hardened production environment

  • TARGET_PLATFORM -- the value is either local or bluemix, more will likely arrive over time. This acts as a feature toggle to allow environment-specific configurations to be checked in alongside other code, but enabled only when on the target platform. For example:

    • Liberty has features that optimize collecting and forwarding logs when running on Bluemix. Setting TARGET_PLATFORM=bluemix will enable this feature and supporting config only in that environment.

    • When running locally, we enable application and config file monitoring. We otherwise disable this, as it is extraneous behavior for remote images.
