Environment Variables with Special Scopes

Introduction

Some environment variables have a special, extended or global scope. Variables with special scope are related to a deployment menthod only. Variables with an extended scope do not directly configure services but functions underneath. Variables with a global scope can configure more than one service.

Examples:

  • The global environment variable OCIS_LOG_LEVEL is available in multiple services.

  • The extended environment variable OCIS_CONFIG_DIR can be used with ocis init.

  • The special environment variable OCIS_RUN_SERVICES is only available with a binary deployment.

Special Environment Variables

The following environment variables are only available with the Binary Setup and do not have any dependency to a release:

  • all releases

OCIS_EXCLUDE_RUN_SERVICES

Extended Environment Variables

The extended variables are defined in the following way:

  • latest

  • 2.0.0
