10.12. 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

  1. 复制 网络和负载均衡器的 ARM 模板 一节中的模板，并将它以 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。

  2. 使用 az CLI 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
    Copy to Clipboard Toggle word wrap
    1
    私有 DNS 区的名称。
    2
    资源名称使用的基本名称 ; 这通常是集群的基础架构 ID。

  3. 在公共区为 API 公共负载均衡器创建一个 api DNS 记录。${BASE_DOMAIN_RESOURCE_GROUP} 变量必须指向存在公共 DNS 区的资源组。

    1. 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`
      Copy to Clipboard Toggle word wrap

    2. 在新的公共区中创建 api 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
      Copy to Clipboard Toggle word wrap

      如果要将集群添加到现有的公共区，您可以在其中创建 api 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

10.12.1. 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：
