You might have certain commands you want to run only in certain environments. For example enabling detailed logging in preview environments or purging your CDN cache for production environments. The deploy and post_deploy hooks can access all runtime environment variables. Use this to vary those hooks based on the environment. Check the PLATFORM_ENVIRONMENT_TYPE variable to see if it’s in a production environment:
.upsun/config.yaml
applications:
  myapp:
    hooks:
      deploy: |
        if [ "$PLATFORM_ENVIRONMENT_TYPE" = production ]; then
          # Run commands only when deploying to production
        else
          # Run commands only when deploying to development or staging environments
        fi
        # Commands to run regardless of the environment
