選擇運算類別時,請務必根據所選類別的資源要求下限和上限,為 Pod 指定資源要求。如果要求低於下限,Autopilot 會自動調高要求。不過,如果要求數量超過上限,Autopilot 就不會部署 Pod,並會顯示錯誤訊息。
選擇 CPU 架構
部分運算類別支援多個 CPU 架構。舉例來說,Scale-Out 類別同時支援 Arm 和 x86 架構。如果未要求特定架構,Autopilot 會佈建具有指定運算級別預設架構的節點。如果 Pod 需要使用其他架構,請在節點選取器或節點親和性規則中,連同運算類別要求一併要求該架構。您要求使用的運算類別必須支援您指定的 CPU 架構。

Before reading this document,\nensure that you're familiar with the concept\nof [compute classes in GKE Autopilot](/kubernetes-engine/docs/concepts/autopilot-compute-classes).\n\nOverview of Autopilot compute classes\n-------------------------------------\n\nAutopilot offers *compute classes* that are designed to run\nworkloads that have specific hardware requirements. These compute classes are\nuseful for workloads such as machine learning and AI tasks, or running real-time\nhigh traffic databases.\n\nThese compute classes are a subset of the Compute Engine\n[machine series](/compute/docs/machine-types#machine_type_comparison), and offer\nflexibility beyond the default Autopilot general-purpose compute class.\nFor example, the `Scale-Out` class turns off simultaneous multi-threading so that each\nvCPU is one physical core.\n\nBased on your individual Pod needs, you can configure your regular\nAutopilot Pods or your Spot Pods to request nodes backed by\nthese compute classes. You can also request specific CPU architecture, such as\n[Arm](https://www.arm.com/architecture), in compute classes that\nsupport that architecture.\n\nBefore you begin\n----------------\n\nBefore you start, make sure that you have performed the following tasks:\n\n- Enable the Google Kubernetes Engine API.\n[Enable Google Kubernetes Engine API](https://console.cloud.google.com/flows/enableapi?apiid=container.googleapis.com)\n- If you want to use the Google Cloud CLI for this task, [install](/sdk/docs/install) and then [initialize](/sdk/docs/initializing) the gcloud CLI. If you previously installed the gcloud CLI, get the latest version by running `gcloud components update`. **Note:** For existing gcloud CLI installations, make sure to set the `compute/region` [property](/sdk/docs/properties#setting_properties). If you use primarily zonal clusters, set the `compute/zone` instead. By setting a default location, you can avoid errors in the gcloud CLI like the following: `One of [--zone, --region] must be supplied: Please specify location`. You might need to specify the location in certain commands if the location of your cluster differs from the default that you set.\n\n\u003c!-- --\u003e\n\n- [Ensure that you have a GKE Autopilot cluster](/kubernetes-engine/docs/how-to/creating-an-autopilot-cluster) running GKE version 1.24.1-gke.1400 or later.\n\nRequest a compute class in your Autopilot Pod\n---------------------------------------------\n\nTo tell Autopilot to place your Pods on a specific compute class, specify the `cloud.google.com/compute-class` label in a [nodeSelector](https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#nodeselector) or a [node affinity rule](https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#node-affinity), such as in the following examples:\n\n### nodeSelector\n\n```yaml\n apiVersion: apps/v1\n kind: Deployment\n metadata:\n name: hello-app\n spec:\n replicas: 3\n selector:\n matchLabels:\n app: hello-app\n template:\n metadata:\n labels:\n app: hello-app\n spec:\n nodeSelector:\n cloud.google.com/compute-class: \"\u003cvar translate=\"no\"\u003eCOMPUTE_CLASS\u003c/var\u003e\"\n containers:\n - name: hello-app\n image: us-docker.pkg.dev/google-samples/containers/gke/hello-app:1.0\n resources:\n requests:\n cpu: \"2000m\"\n memory: \"2Gi\"\n \n```\n\nReplace \u003cvar translate=\"no\"\u003eCOMPUTE_CLASS\u003c/var\u003e with the name of the [compute class](/kubernetes-engine/docs/concepts/autopilot-compute-classes#when-to-use)\nbased on your use case, such as `Scale-Out`. If you select `Accelerator`,\nyou must also specify a compatible GPU. For instructions, see [Deploy GPU workloads in Autopilot](/kubernetes-engine/docs/how-to/autopilot-gpus). If\nyou select `Performance`, you can optionally select a Compute Engine machine\nseries in the node selector. If you don't specify a machine series, GKE uses the\nC4 machine series depending on [regional\navailability](/compute/docs/regions-zones#available). For instructions, see [Run CPU-intensive workloads with optimal\nperformance](/kubernetes-engine/docs/how-to/performance-pods).\n\n### nodeAffinity\n\n```yaml\n apiVersion: apps/v1\n kind: Deployment\n metadata:\n name: hello-app\n spec:\n replicas: 3\n selector:\n matchLabels:\n app: hello-app\n template:\n metadata:\n labels:\n app: hello-app\n spec:\n terminationGracePeriodSeconds: 25\n containers:\n - name: hello-app\n image: us-docker.pkg.dev/google-samples/containers/gke/hello-app:1.0\n resources:\n requests:\n cpu: \"2000m\"\n memory: \"2Gi\"\n ephemeral-storage: \"1Gi\"\n affinity:\n nodeAffinity:\n requiredDuringSchedulingIgnoredDuringExecution:\n nodeSelectorTerms:\n - matchExpressions:\n - key: cloud.google.com/compute-class\n operator: In\n values:\n - \"\u003cvar translate=\"no\"\u003eCOMPUTE_CLASS\u003c/var\u003e\"\n \n```\n\nReplace \u003cvar translate=\"no\"\u003eCOMPUTE_CLASS\u003c/var\u003e with the name of the\n[compute\nclass](/kubernetes-engine/docs/concepts/autopilot-compute-classes#when-to-use) based on your use case, such as `Scale-Out`. If you select\n`Accelerator`, you must also specify a compatible GPU. For instructions, see [Deploy GPU workloads in Autopilot](/kubernetes-engine/docs/how-to/autopilot-gpus).\nIf you select `Performance`, you can optionally select a\nCompute Engine machine series in the node selector. If you don't specify a machine series, GKE uses the C4\nmachine series depending on [regional\navailability](/compute/docs/regions-zones#available). For instructions, see [Run CPU-intensive workloads with\noptimal performance](/kubernetes-engine/docs/how-to/performance-pods).\n\nYou can also request specific compute classes for your Spot Pods.\n\n### Specify resource requests\n\nWhen you choose a compute class, make sure that you specify resource requests\nfor your Pods based on the\n[Minimum and maximum resource requests](/kubernetes-engine/docs/concepts/autopilot-resource-requests#min-max-requests)\nfor your selected class. If your requests are less than the minimum,\nAutopilot automatically scales your requests up. However, if your\nrequests are greater than the maximum, Autopilot does not deploy your\nPods and displays an error message.\n\nChoose a CPU architecture\n-------------------------\n\nSome compute classes support multiple CPU architectures. For example, the\n`Scale-Out` class supports both Arm and x86 architectures. If you\ndon't request a specific architecture, Autopilot provisions nodes that\nhave the default architecture of the specified compute class. If your Pods need\nto use a different architecture, request that architecture in your node selector\nor node affinity rule, alongside your compute class request. The compute class\nthat you request must support the CPU architecture you specify.\n\nFor instructions, refer to\n[Deploy Autopilot Pods on Arm architecture](/kubernetes-engine/docs/how-to/autopilot-arm-workloads).\n\nWhat's next\n-----------\n\n- [Learn more about Autopilot cluster architecture](/kubernetes-engine/docs/concepts/autopilot-architecture).\n- [Learn about the lifecycle of Pods](https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/).\n- [Learn about the available Autopilot compute classes](/kubernetes-engine/docs/concepts/autopilot-compute-classes).\n- [Read about the default, minimum, and maximum resource requests for each\n platform](/kubernetes-engine/docs/concepts/autopilot-resource-requests)."]]
