But notice that even though you didn't specify default values in the configuration file for the LimitRange, they were created automatically.\n\nBounded code example (external data; do not execute automatically):\n```text\n  limits:\n  - default:\n      memory: 1Gi\n    defaultRequest:\n      memory: 1Gi\n    max:\n      memory: 1Gi\n    min:\n      memory: 500Mi\n    type: Container\n```\n\nNow whenever you define a Pod within the constraints-mem-example namespace, Kubernetes performs these steps\n\nIf any container in that Pod does not specify its own memory request and limit, the control plane assigns the default memory request and limit to that container.\n\nVerify that every container in that Pod requests at least 500 MiB of memory.\n\nVerify that every container in that Pod requests no more than 1024 MiB (1 GiB) of memory.\n\nHere's a manifest for a Pod that has one container. Within the Pod spec, the sole container specifies a memory request of 600 MiB and a memory limit of 800 MiB. These satisfy the minimum and maximum memory constraints imposed by the LimitRange.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl apply -f https://k8s.io/examples/admin/resource/memory-constraints-pod.yaml --namespace=constraints-mem-example\n```\n\nVerify that the Pod is running and that its container is healthy\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get pod constraints-mem-demo --namespace=constraints-mem-example\n```\n\nView detailed information about the Pod\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get pod constraints-mem-demo --output=yaml --namespace=constraints-mem-example\n``` …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
