In this tutorial, the DRA driver is deployed on all nodes, and is advertising mock GPUs on all nodes, all of which have enough capacity advertised to satisfy the Pod's claim, so Kubernetes can schedule this Pod on any node and can allocate any of the mock GPUs on that node.\n\nWhen Kubernetes allocates a mock GPU to a Pod, the example driver adds environment variables in each container it is allocated to in order to indicate which GPUs _would_ have been injected into them by a real resource driver and how they would have been configured, so you can check those environment variables to see how the Pods have been handled by the system.\n\nCheck the Pod logs, which report the name of the mock GPU that was allocated\n\nBounded code example (external data; do not execute automatically):\n```shell\n    kubectl logs pod0 -c ctr0 -n dra-tutorial | grep -E \"GPU_DEVICE_[0-9]+=\" | grep -v \"RESOURCE_CLAIM\"\n```\n\nBounded code example (external data; do not execute automatically):\n```text\n    declare -x GPU_DEVICE_0=\"gpu-0\"\n```\n\nCheck the state of the ResourceClaim object\n\nBounded code example (external data; do not execute automatically):\n```shell\n    kubectl get resourceclaims -n dra-tutorial\n```\n\nBounded code example (external data; do not execute automatically):\n```text\n    NAME       STATE                AGE\n    some-gpu   allocated,reserved   34s\n```\n\nCheck the details of the some-gpu ResourceClaim. The status stanza of the ResourceClaim has information about the allocated device and the Pod it has been reserved for\n\nBounded code example (external data; do not execute automatically):\n```shell\n    kubectl get resourceclaim some-gpu -n dra-tutorial -o yaml\n```\n\nTo check how the driver handled device allocation, get the logs for the driver DaemonSet Pods\n\nBounded code example (external data; do not execute automatically):\n```shell\n    kubectl logs -l app.kubernetes.io/name=dra-example-driver -n dra-tutorial\n``` …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
