5.9.13. 在 Azure 中创建网络和负载均衡组件
您必须在 Microsoft Azure 中配置网络和负载均衡，供您的 OpenShift Container Platform 集群使用。创建这些组件的一种方法是修改提供的 Azure Resource Manager（ARM）模板。
注意
如果不使用提供的 ARM 模板来创建 Azure 基础架构，您必须检查提供的信息并手动创建基础架构。如果集群没有正确初始化，您可能需要联系红帽支持并提供您的安装日志。
先决条件
- 配置 Azure 帐户。
- 为集群生成 Ignition 配置文件。
- 在 Azure 中创建和配置 VNet 及相关子网。
流程
-
复制网络和负载均衡器的 ARM 模板一节中的模板，并将以
03_infra.json保存到集群的安装目录中。此模板描述了集群所需的网络和负载均衡对象。 使用
azCLI 创建部署：$ az deployment group create -g ${RESOURCE_GROUP} \ --template-file "<installation_directory>/03_infra.json" \ --parameters privateDNSZoneName="${CLUSTER_NAME}.${BASE_DOMAIN}" \ 1 --parameters baseName="${INFRA_ID}"2在公共区为 API 公共负载均衡器创建一个
apiDNS 记录。${BASE_DOMAIN_RESOURCE_GROUP}变量必须指向存在公共 DNS 区的资源组。导出以下变量：
$ export PUBLIC_IP=`az network public-ip list -g ${RESOURCE_GROUP} --query "[?name=='${INFRA_ID}-master-pip'] | [0].ipAddress" -o tsv`在一个新的公共区中创建 DNS 记录：
$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${CLUSTER_NAME}.${BASE_DOMAIN} -n api -a ${PUBLIC_IP} --ttl 60如果您要将集群添加到现有的公共区，您可以在其中创建 DNS 记录：
$ az network dns record-set a add-record -g ${BASE_DOMAIN_RESOURCE_GROUP} -z ${BASE_DOMAIN} -n api.${CLUSTER_NAME} -a ${PUBLIC_IP} --ttl 60
5.9.13.1. 网络和负载均衡器的 ARM 模板
您可以使用以下 Azure Resource Manager（ARM）模板来部署 OpenShift Container Platform 集群所需的网络对象和负载均衡器：
