Build arguments
Docker build arguments & static service environment variables
Build arguments are key:value pairs that will be used to initialize a build with either
docker-compose
or static service environment variables. A static service is any service that doesn't require a container. Visit our guide to static service deployment for more details.Build arguments can be global and used for all your applications, or specific to a single application.
Global build arguments can be kept in your Account Settings under the Builds tab. Secret environment variables that are only relevant to a single application can be added to App Settings in the "Advanced Settings" section so that they aren't exposed to other containers.
Navigate to Account Settings screen by clicking the sliders icon in the upper right. Select the Builds tab.

An example use-case for global build arguments is an API key for a static build.
