Environment variables reference
Environment variables for Self-hosted Retool deployments.
Environment variables control or override certain functions and characteristics of Self-hosted Retool instances. Some Retool features require you to set environment variables, such as SSO or Source Control.
Only configure environment variables when needed. You can configure many environment variables from your organization's Settings rather than directly editing your deployment's configuration file.
You must restart your instance after setting any variables for them to take effect.
