Antes de aplicar a configuração e instalar os gráficos do Helm híbridos, é necessário verificar
se o cluster do Kubernetes está pronto para a instalação da Apigee híbrida.
Para verificar a prontidão do cluster, crie um arquivo YAML com uma definição de job do Kubernetes e aplique-o com comandos kubectl para verificar o cluster.
Em seguida, verifique o status do job de teste do Kubernetes com um comando kubectl get jobs.
Verifique se kubectl está definido para o contexto correto usando o seguinte comando.
O contexto atual será definido como o cluster ao qual você está implantando a Apigee híbrida.
kubectl config current-context
O resultado precisa incluir o nome do cluster em que você está implantando a Apigee híbrida. Por
exemplo, no GKE, o nome do contexto geralmente está no formato
gke_project-id_cluster-location_cluster-name, como
em:
gke_my-project_us-central1_my-cluster
Se o nome do cluster não for correspondente, o comando a seguir receberá as
credenciais da gcloud do cluster e definirá o contexto kubectl:
A saída deve mostrar que a conta de serviço e o job foram criados. Exemplo:
kubectl apply -f $APIGEE_HELM_CHARTS_HOME/cluster-check/apigee-k8s-cluster-ready-check.yaml
serviceaccount/apigee-k8s-cluster-ready-check created
job.batch/apigee-k8s-cluster-ready-check created
Verifique o status do job do Kubernetes com o seguinte comando:
kubectl get jobs apigee-k8s-cluster-ready-check
Se o cluster estiver pronto, a saída será semelhante a esta:
NAME COMPLETIONS DURATION AGE
apigee-k8s-cluster-ready-check 1/1 8s 1h23m
Se o teste falhar e o cluster não estiver pronto, a saída será semelhante a esta:
NAME COMPLETIONS DURATION AGE
apigee-k8s-cluster-ready-check 0/1 44s 44s
Procure o número de conclusões:
1/1 Seu cluster está pronto para a instalação da Apigee híbrida.
0/1 O teste falhou. O cluster não está pronto. Prossiga para as etapas a seguir a fim de
solucionar os problemas do cluster.
Se o teste não foi bem-sucedido, verifique os registros com os comandos a seguir.
Confira o nome do pod para o job de pré-verificação do cluster:
kubectl get pods | grep apigee-k8s-cluster-ready-check
Verifique os registros do Kubernetes para o pod:
kubectl logs pod_name
Em que pod_name é o nome do pod apigee-k8s-cluster-ready-check.
Faça uma limpeza antes de prosseguir para a próxima etapa. Exclua o job do Kubernetes com o seguinte
comando:
Você acabou de verificar se o cluster da Apigee híbrida está pronto. Em seguida, instale os gráficos para
aplicar a configuração ao ambiente de execução híbrido.
Solução de problemas
Verificação de DNS do Cassandra: se você encontrou registros de erros semelhantes a
DNS resolution was successful but IP doesn't match POD IP,
could not resolve hostname ou error determining hostname, isso significa que o
DNS do cluster não está configurado corretamente para uma configuração multirregional. Ignore esse erro se
você não pretende usar a configuração multirregional.
Verificação de conectividade do plano de controle: se você encontrar registros de erro semelhantes a
error creating TCP connection with host, será necessário resolver a conectividade
do cluster com o apigee.googleapis.com e executar o job novamente.

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"]]
