CKAN Environment Variables extension enables configuration of CKAN settings through environment variables, making it ideal for containerized deployments and DevOps workflows. The extension maps environment variables to CKAN configuration settings using a specific naming convention where variables must be uppercase, start with CKAN or CKANEXT, and use double underscores instead of periods. For example, ckan.site_id becomes CKAN__SITE_ID. This approach simplifies configuration management in Docker containers, Kubernetes deployments, and CI/CD pipelines by eliminating the need to modify configuration files directly. The extension processes environment variables at startup and overrides corresponding configuration file settings, providing a clean separation between code and configuration.
