For example, if a node supports 2048KiB and 1048576KiB page sizes, it will expose a schedulable resources hugepages-2Mi and hugepages-1Gi. Unlike CPU or memory, huge pages do not support overcommit. Note that when requesting hugepage resources, either memory or CPU resources must be requested as well.\n\nA pod may consume multiple huge page sizes in a single pod spec. In this case it must use medium: HugePages- notation for all volume mounts.\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: v1\nkind: Pod\nmetadata:\n  name: huge-pages-example\nspec:\n  containers:\n  - name: example\n    image: fedora:latest\n    command:\n    - sleep\n    - inf\n    volumeMounts:\n    - mountPath: /hugepages-2Mi\n      name: hugepage-2mi\n    - mountPath: /hugepages-1Gi\n      name: hugepage-1gi\n    resources:\n      limits:\n        hugepages-2Mi: 100Mi\n        hugepages-1Gi: 2Gi\n        memory: 100Mi\n      requests:\n        memory: 100Mi\n  volumes:\n  - name: hugepage-2mi\n    emptyDir:\n      medium: HugePages-2Mi\n  - name: hugepage-1gi\n    emptyDir:\n      medium: HugePages-1Gi\n```\n\nA pod may use medium: HugePages only if it requests huge pages of one size.\n\nBounded code example (external data; do not execute automatically):\n```yaml\napiVersion: v1\nkind: Pod\nmetadata:\n  name: huge-pages-example\nspec:\n  containers:\n  - name: example\n    image: fedora:latest\n    command:\n    - sleep\n    - inf\n    volumeMounts:\n    - mountPath: /hugepages\n      name: hugepage\n    resources:\n      limits:\n        hugepages-2Mi: 100Mi\n        memory: 100Mi\n      requests:\n        memory: 100Mi\n  volumes:\n  - name: hugepage\n    emptyDir:\n      medium: HugePages\n``` …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
