請使用下列指令檢查 Kubernetes 工作的狀態：
kubectl get jobs apigee-k8s-cluster-ready-check
如果叢集已準備就緒，輸出內容應如下所示：
NAME COMPLETIONS DURATION AGE
apigee-k8s-cluster-ready-check 1/1 8s 1h23m
如果測試失敗且叢集尚未就緒，輸出內容會如下所示：
NAME COMPLETIONS DURATION AGE
apigee-k8s-cluster-ready-check 0/1 44s 44s
查看完成次數：
1/1 成功，您的叢集已準備好安裝 Apigee Hybrid。
0/1 測試失敗。叢集尚未就緒。請按照下列步驟排解叢集問題。
如果測試未成功，請使用下列指令檢查記錄。
取得叢集預先檢查工作所需的 pod 名稱：
kubectl get pods | grep apigee-k8s-cluster-ready-check
Cassandra DNS 檢查：如果您發現類似 DNS resolution was successful but IP doesn't match POD IP、could not resolve hostname 或 error determining hostname 的錯誤記錄，表示叢集 DNS 未正確設定為多區設定。如果您不打算設定多地區，可以忽略這項錯誤。
控制平面連線檢查：如果您發現類似 error creating TCP connection with host 的錯誤記錄，就必須解決叢集與 apigee.googleapis.com 之間的連線問題，並重新執行工作。

For more information, see [Supported versions](/apigee/docs/hybrid/supported-platforms#supported-versions).\n\nCheck hybrid cluster readiness\n------------------------------\n\nBefore applying your configuration and installing the hybrid helm charts, you should\ncheck that your Kubernetes cluster is ready for Apigee hybrid installation.\n\n\nTo check the readiness of your cluster, you will create a YAML file with a Kubernetes Job\ndefinition and apply that file with `kubectl` commands to check the cluster.\nYou then check the status of the Kubernetes test job with a `kubectl get jobs` command.\n\n1. Verify that `kubectl` is set to the correct context using the following command. The current context should be set to the cluster to which you are deploying Apigee hybrid. \n\n ```\n kubectl config current-context\n ```\n\n The result should include the name of the cluster you are deploying Apigee hybrid in. For\n example, on GKE, the context name is usually in the form\n `gke_`\u003cvar translate=\"no\"\u003eproject-id\u003c/var\u003e`_`\u003cvar translate=\"no\"\u003ecluster-location\u003c/var\u003e`_`\u003cvar translate=\"no\"\u003ecluster-name\u003c/var\u003e, as\n in: \n\n ```\n gke_my-project_us-central1_my-cluster\n ```\n\n If the name cluster name in the context does not match, the following command will get the\n `gcloud` credentials of the cluster and set the `kubectl` context:\n\n ### Regional clusters\n\n ```\n gcloud container clusters get-credentials $CLUSTER_NAME \\\n --region $CLUSTER_LOCATION \\\n --project $PROJECT_ID\n ```\n\n ### Zonal clusters\n\n ```\n gcloud container clusters get-credentials $CLUSTER_NAME \\\n --zone $CLUSTER_LOCATION \\\n --project $PROJECT_ID\n ```\n2. In your helm-charts directory, create a `cluster-check` directory: \n\n ```\n mkdir $APIGEE_HELM_CHARTS_HOME/cluster-check\n ```\n3. In the `$APIGEE_HELM_CHARTS_HOME/cluster-check` directory, create a file named `apigee-k8s-cluster-ready-check.yaml` with the following contents: \n\n ```\n apiVersion: v1\n kind: ServiceAccount\n metadata:\n name: apigee-k8s-cluster-ready-check\n ---\n apiVersion: rbac.authorization.k8s.io/v1\n kind: ClusterRoleBinding\n metadata:\n name: cluster-check-admin\n roleRef:\n apiGroup: rbac.authorization.k8s.io\n kind: ClusterRole\n name: cluster-admin\n subjects:\n - apiGroup: \"\"\n kind: ServiceAccount\n namespace: default\n name: apigee-k8s-cluster-ready-check\n ---\n apiVersion: batch/v1\n kind: Job\n metadata:\n name: apigee-k8s-cluster-ready-check\n spec:\n template:\n spec:\n hostNetwork: true\n serviceAccountName: apigee-k8s-cluster-ready-check\n containers:\n - name: manager\n image: gcr.io/apigee-release/hybrid/apigee-operators:1.12.4\n command:\n - /manager\n args:\n - --k8s-cluster-ready-check\n env:\n - name: POD_IP\n valueFrom:\n fieldRef:\n fieldPath: status.podIP\n securityContext:\n runAsGroup: 998\n runAsNonRoot: true\n runAsUser: 999\n restartPolicy: Never\n backoffLimit: 1\n ```\n4. Apply the `apigee-k8s-cluster-ready-check.yaml` with the following `kubectl` command. This will run the test: \n\n ```\n kubectl apply -f $APIGEE_HELM_CHARTS_HOME/cluster-check/apigee-k8s-cluster-ready-check.yaml\n ```\n\n\n The output should show that the service account and job were created. For example: \n\n kubectl apply -f $APIGEE_HELM_CHARTS_HOME/cluster-check/apigee-k8s-cluster-ready-check.yaml\n serviceaccount/apigee-k8s-cluster-ready-check created\n job.batch/apigee-k8s-cluster-ready-check created\n\n5. Check the status of the Kubernetes job with the following command: \n\n ```\n kubectl get jobs apigee-k8s-cluster-ready-check\n ```\n\n\n If your cluster is ready, the output should look something like: \n\n ```\n NAME COMPLETIONS DURATION AGE\n apigee-k8s-cluster-ready-check 1/1 8s 1h23m\n ```\n\n\n If the test failed and your cluster is not ready, the output will look something like: \n\n ```\n NAME COMPLETIONS DURATION AGE\n apigee-k8s-cluster-ready-check 0/1 44s 44s\n ```\n\n Look for the number of completions:\n - **1/1** Success, your cluster is ready for Apigee hybrid installation.\n - **0/1** The test failed. The cluster is not ready. Proceed to the following steps to troubleshoot the cluster.\n\n \u003cbr /\u003e\n\n6. If the test did not succeed, check the logs with the following commands.\n 1. Get the name of the pod for the cluster pre-check job: \n\n ```\n kubectl get pods | grep apigee-k8s-cluster-ready-check\n ```\n 2. Get the Kubernetes logs for the pod: \n\n ```\n kubectl logs pod_name\n ```\n\n\n Where \u003cvar translate=\"no\"\u003epod_name\u003c/var\u003e is the name of the apigee-k8s-cluster-ready-check pod.\n7. Clean up before proceeding to the next step. Delete the Kubernetes job with the following command: \n\n ```\n kubectl delete -f $APIGEE_HELM_CHARTS_HOME/cluster-check/apigee-k8s-cluster-ready-check.yaml\n ```\n\n\n The output should show that the service account and job were deleted. For example: \n\n kubectl delete -f $APIGEE_HELM_CHARTS_HOME/cluster-check/apigee-k8s-cluster-ready-check.yaml\n serviceaccount \"apigee-k8s-cluster-ready-check\" deleted\n job.batch \"apigee-k8s-cluster-ready-check\" deleted\n\n| **Tip:** On some platforms, like Google Distributed Cloud, you may see DNS resolution errors. If the DNS resolution is not working, try this workaround.\n|\n|\n| Add a static host entry in `/etc/hosts` file of each cassandra worker node\n| similar to the following: \n|\n| ```\n| echo -e \"\\\\n127.0.1.1 ${HOSTNAME}\" \u003e\u003e \"/etc/hosts\"\n| ```\n|\n|\n| or \n|\n| ```\n| \"\\\\nWORKER-NODE-IP ${HOSTNAME}\" \u003e\u003e \"/etc/hosts\"\n| ```\n\nYou have now made sure your Apigee hybrid cluster is ready. Next, let's install the charts to\napply your configuration to the hybrid runtime.\n\nTroubleshooting\n---------------\n\n1. Cassandra DNS check: If you find error logs similar to `DNS resolution was successful but IP doesn't match POD IP`, `could not resolve hostname` or `error determining hostname` it means your cluster DNS is not configured correctly for a multi-region setup. You can ignore this error if you do not intend to set up multi-region.\n2. Control Plane connectivity check: If you find error logs similar to `error creating TCP connection with host` then you need to resolve the connectivity from cluster to apigee.googleapis.com and re-run the job.\n\nNext step\n---------\n\n\u003cbr /\u003e\n\n[1](/apigee/docs/hybrid/v1.12/install-create-cluster) [2](/apigee/docs/hybrid/v1.12/install-download-charts) [3](/apigee/docs/hybrid/v1.12/install-create-namespace) [4](/apigee/docs/hybrid/v1.12/install-service-accounts) [5](/apigee/docs/hybrid/v1.12/install-create-tls-certificates) [6](/apigee/docs/hybrid/v1.12/install-create-overrides) [7](/apigee/docs/hybrid/v1.12/install-enable-synchronizer-access) [8](/apigee/docs/hybrid/v1.12/install-cert-manager) [9](/apigee/docs/hybrid/v1.12/install-crds) [10](/apigee/docs/hybrid/v1.12/install-check-cluster) [(NEXT) Step 11: Install Apigee hybrid using Helm charts](/apigee/docs/hybrid/v1.12/install-helm-charts) [12](/apigee/docs/hybrid/v1.12/install-workload-identity)\n\n\u003cbr /\u003e"]]
