Projects, services, and private networking

Project model

A project is one private network for a full app stack. Your container apps live there together and talk over internal DNS. Each app runs from a container image you push. See Deploy with GitHub Actions. Managed Postgres, MySQL, and Redis are part of the project model and run inside the same private network. See Managed databases.

• Each container app has a Visibility you pick when you create it: Public gets a managed *.alawadi.cloud subdomain with TLS automatically (you never type a domain); Internal stays on internal DNS only, reachable from other apps in the same project.
• Use the app's name like api for private traffic between apps in the project.
• Link a managed database to your app and its connection string is injected as an environment variable. You read DATABASE_URL (Postgres or MySQL) or REDIS_URL (Redis) from the environment, and you never handle the password yourself.
• Project quotas cover every app in the project.
• Deleting a project deletes its apps and managed add-ons.
