# Rez queue environment for Deadline Cloud customer-managed fleets
<a name="examples-queue-env-rez"></a>

The [rez\_queue\_env.yaml](https://github.com/aws-deadline/deadline-cloud-samples/blob/mainline/queue_environments/rez_queue_env.yaml) queue environment provides the same functionality as the conda queue environments but for the [Rez](https://rez.readthedocs.io/) package manager. The queue environment works in a farm with customer-managed fleets that have a shared file system for the Rez package repository.

To use this queue environment on a customer-managed fleet, install Rez on the worker hosts (for example, in your AMI). Modify the `RezRepositories` default value to point to the shared file system path of your Rez package repository.

When you submit a job, set the `RezPackages` parameter to the list of packages the job needs. The queue environment creates and activates a Rez environment containing the requested packages and their dependencies before each job runs.
