Resources
Choose CPU, RAM and storage according to your workload and displayed cost. Start with a suitable small configuration, observe real metrics and increase capacity when measurements justify it. Runtime files are not a substitute for durable data storage.
Ports
The deployment form has a public port field. Set the port your web app listens on and bind the app to 0.0.0.0. Do not use this field to expose a database. Use private endpoints when calling other products in the same organization.
Environment variables
Configure the variables your code reads in Console. Mark passwords, database URLs and access keys as secrets to hide their values in the UI. Your code can still print secrets to logs; do not log passwords or connection URLs. Apply changes and redeploy as required.
