Connect a project

1

Link the database

Open the project overview, choose the database connection action, select the instance, and confirm the link.
2

Add environment variables

Add DATABASE_URL, or add the individual host, port, database, user, and password values required by your framework.
3

Redeploy the project

Save the variables and start a new deployment. New values are loaded when the container starts.
Pxxl routes user connections through its managed database router. Use the host and port shown by Pxxl. localhost inside a project container points to that container, not to the database.

​
Common environment variables

PostgreSQL
MySQL
Replace the placeholders with values from Pxxl. Do not commit the finished connection string.
