-# This file defines the global default configuration for docker deployments.
-# It is tracked in source control. For temporary modifications, please create
-# a separate file called ".env.local" (it's in .gitignore, so won't be tracked).
-# If a variable is defined in both files, the value in .env.local will be used.
-#
-# About the deployment procedure:
-#   We use Docker Compose to build images and launch containers for various services
-#   that make up our software suite:
-#     - sparkd
-#     - pubsub
-#     - md-publisher
-#     - webapp (DSQA on the web)
-#     - api-server (websocket based)
-#   From inside a devcontainer, you can launch all services in separate containers
-#   on your machine by running:
-#
-#     tools/deploy.sh
-#
-#   This script builds release versions for each service, packaged (generally) in
-#   self-contained directories. Next, it runs a few "docker compose" commands to
-#   build docker images loaded with the self-contained binaries from the previous
-#   step, and start containers with those images to run each service. To view the
-#   commands that deploy.sh runs internally (without actually running them), run:
-#
-#     tools/deploy.sh --dry-run
-#
-#   For additional information/help, run:
-#
-#     tools/deploy.sh --help
-#
