5.9.15. 在 Azure 中创建 control plane 机器
您必须在 Microsoft Azure 中创建 control plane 机器,供您的集群使用。创建这些机器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 control plane 机器,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。
- 在 Azure 中创建和配置联网及负载均衡器。
- 创建 control plane 和计算角色。
- 创建 bootstrap 机器。
流程
-
复制 control plane 机器的 ARM 模板一节中的模板,并将它以
05_masters.json
保存到集群的安装目录中。此模板描述了集群所需的 control plane 机器。 导出 control plane 机器部署所需的以下变量:
$ export MASTER_IGNITION=`cat <installation_directory>/master.ign | base64 | tr -d '\n'`
使用
az
CLI 创建部署:$ az deployment group create -g ${RESOURCE_GROUP} \ --template-file "<installation_directory>/05_masters.json" \ --parameters masterIgnition="${MASTER_IGNITION}" \ 1 --parameters sshKeyData="${SSH_KEY}" \ 2 --parameters privateDNSZoneName="${CLUSTER_NAME}.${BASE_DOMAIN}" \ 3 --parameters baseName="${INFRA_ID}"4
