Configure Minimum and Maximum Memory Constraints for a Namespace — Create a Pod that does not specify any memory request or limit
Here's a manifest for a Pod that has one container. The container does not specify a memory request, and it does not specify a memory limit. Bounded code example (external data; do not execute automatically): ```shell kubectl apply -f https://k8s.io/examples/admin/resource/memory-constraints-pod-4.y

Bounded code example (external data; do not execute automatically):
```shell
kubectl get pod constraints-mem-demo-4 --namespace=constraints-mem-example --output=yaml
```
The output shows that the Pod's only container has a memory request of 1 GiB and a memory limit of 1 GiB. How did that container get those values?
Bounded code example (external data; do not execute automatically):
```text
resources:
limits:
memory: 1Gi
requests:
memory: 1Gi
```
Because your Pod did not define any memory request and limit for that container, the cluster applied a default memory request and limit from the LimitRange.
This means that the definition of that Pod shows those values. You can check it using kubectl describe
