Environment Variables

Set variables when you add a service, or later under the service's Variable tab. Changes apply on the next deployment.

Raw editing

Click Edit Raw Variables to paste .env-style lines:

NODE_ENV=production
API_URL="https://api.example.com"
# comments and blank lines are ignored

Built-in variables

Every service gets these, which you can reference in your own values with ${NAME}:

Variable	Value
PORT	The service's first port
<PORT>_PORT	Each port by its name, such as WEB_PORT
ZENAVO_<PORT>_DOMAIN	The domain bound to that port, such as ZENAVO_WEB_DOMAIN
ZENAVO_<PORT>_URL	https:// plus that domain
CONTAINER_HOSTNAME	The service name

Sharing between services

A service can expose some of its variables to the rest of the project; databases do this for their connection details (Databases). Other services then reference them as ${NAME}.

Generated passwords

${PASSWORD} in a template becomes a random password the first time the project is saved, and stays the same afterwards.

Secrets

Variable values are encrypted at rest, hidden from team viewers, and redacted from build and runtime logs.
