Environment Variables¶

The following process-level environment variables tune the client. They are read once when deepracer is imported.

Variable	Default	Controls
`DEEPRACER_IMAGE`	`uzairakbar/` `deepracer:v0`	The simulator image to use.
`DEEPRACER_BACKEND`	(auto-detected)	Container runtime: `docker`, `podman`, or `apptainer`.
`DEEPRACER_MAX_ENVS`	`4`	Maximum simulators one process may run at once.
`DEEPRACER_READY_TIMEOUT`	`300`	Seconds to wait for a simulator to become ready before failing.

Example
