Bevor Sie Ihre Konfiguration anwenden und die Hybrid-Laufzeit installieren, sollten Sie prüfen, ob Ihr Kubernetes-Cluster für die Installation von Apigee Hybrid bereit ist.
Um die Bereitschaft Ihres Clusters zu prüfen, erstellen Sie eine YAML-Datei mit einer Kubernetes-Jobdefinition und wenden diese Datei mit kubectl-Befehlen an.
Anschließend prüfen Sie den Status des Kubernetes-Testjobs mit dem Befehl kubectl get jobs.
Prüfen Sie mit dem folgenden Befehl, ob kubectl auf den richtigen Kontext eingestellt ist.
Der aktuelle Kontext sollte auf den Cluster eingestellt werden, für den Sie Apigee Hybrid bereitstellen.
kubectl config current-context
Das Ergebnis sollte den Namen des Clusters enthalten, in dem Sie Apigee Hybrid bereitstellen. Bei GKE hat der Kontextname beispielsweise normalerweise das Format gke_project-id_cluster-location_cluster-name, wie in:
gke_my-project_us-central1_my-cluster
Wenn der Clustername im Kontext nicht übereinstimmt, ruft der folgende Befehl die gcloud-Anmeldedaten des Clusters ab und legt den kubectl-Kontext fest:
Sie haben nun sichergestellt, dass Ihr Apigee Hybrid-Cluster bereit ist. Als Nächstes wenden Sie Ihre Konfiguration auf die Hybrid-Laufzeit an und schließen die Installation von Apigee Hybrid ab.
Fehlerbehebung
Cassandra-DNS-Prüfung: Wenn Sie Fehlerlogs finden, die DNS resolution was successful but IP doesn't match POD IP, could not resolve hostname oder error determining hostname ähneln, bedeutet dies, dass Ihr Cluster-DNS für eine multiregionale Einrichtung nicht korrekt konfiguriert ist. Sie können diese Fehlermeldung ignorieren, wenn Sie nicht beabsichtigen, mehrere Regionen einzurichten.
Konnektivitätsprüfung der Steuerungsebene: Wenn Sie Fehlerlogs wie error creating TCP connection with host finden, müssen Sie die Verbindung vom Cluster zu apigee.googleapis.com lösen und den Job noch einmal ausführen.

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 runtime, you should check\nthat 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 hybrid files directory, create a `cluster-check` directory: \n\n ```\n mkdir $HYBRID_FILES/cluster-check\n ```\n3. In the `$HYBRID_FILES/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: 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:1.10.0\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 $HYBRID_FILES/cluster-check/apigee-k8s-cluster-ready-check.yaml\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 should 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 $HYBRID_FILES/cluster-check/apigee-k8s-cluster-ready-check.yaml\n ```\n\n| **Tip:** On some platforms, like Anthos on Bare Metal or GKE on-prem, 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 apply your\nconfiguration to the hybrid runtime and complete your installation of Apigee hybrid.\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 setup 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\n[1](/apigee/docs/hybrid/v1.11/install-create-cluster) [2](/apigee/docs/hybrid/v1.11/install-cert-manager) [3](/apigee/docs/hybrid/v1.11/install-apigeectl) [4](/apigee/docs/hybrid/v1.11/install-service-accounts) [5](/apigee/docs/hybrid/v1.11/install-create-tls-certificates) [6](/apigee/docs/hybrid/v1.11/install-configure-cluster) [7](/apigee/docs/hybrid/v1.11/install-enable-synchronizer-access) [8](/apigee/docs/hybrid/v1.11/install-check-cluster) [(NEXT) Step 9: Install the hybrid runtime](/apigee/docs/hybrid/v1.11/install-hybrid-runtime) [10](/apigee/docs/hybrid/v1.11/install-workload-identity)\n\n\u003cbr /\u003e"]]
