Environment variables

What it is

Section titled “What it is”

Environment variables are key/value pairs injected into your app’s process environment at runtime. uploy encrypts values at rest with AES-256-GCM.

Types

Section titled “Types”
  • User-defined. Set on the app’s Environment tab.
  • Auto-injected. Set by uploy itself — e.g. DATABASE_URL when a managed Postgres is attached. These cannot be overridden manually.

Name rules

Section titled “Name rules”

Names must match ^[A-Z][A-Z0-9_]*$ — that is, start with an uppercase letter and contain only uppercase letters, digits, and underscores.

How to use

Section titled “How to use”

See the Configure environment variables guide.

Limits & defaults

Section titled “Limits & defaults”
  • Applying changes restarts the app.
