Code executor environment variables

Reference documentation of environment variables for the code-executor service.

code-executor environment variables available for use with Self-hosted Retool deployments. You should only set these environment variables on containers running tryretool/code-executor-service images.

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.
