5.9.14. 在 Azure 中创建 bootstrap 机器

您必须在 Microsoft Azure 中创建 bootstrap 机器,以便在 OpenShift Container Platform 集群初始化过程中使用。创建此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 bootstrap 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。

流程

  1. 复制 bootstrap 机器的 ARM 模板一节中的模板,并将它以 04_bootstrap.json 保存到集群的安装目录中。此模板描述了集群所需的 bootstrap 机器。
  2. 导出 bootstrap 机器部署所需的以下变量:

    $ export BOOTSTRAP_URL=`az storage blob url --account-name ${CLUSTER_NAME}sa --account-key ${ACCOUNT_KEY} -c "files" -n "bootstrap.ign" -o tsv`
    $ export BOOTSTRAP_IGNITION=`jq -rcnM --arg v "3.2.0" --arg url ${BOOTSTRAP_URL} '{ignition:{version:$v,config:{replace:{source:$url}}}}' | base64 | tr -d '\n'`
  3. 使用 az CLI 创建部署:

    $ az deployment group create -g ${RESOURCE_GROUP} \
      --template-file "<installation_directory>/04_bootstrap.json" \
      --parameters bootstrapIgnition="${BOOTSTRAP_IGNITION}" \ 1
      --parameters sshKeyData="${SSH_KEY}" \ 2
      --parameters baseName="${INFRA_ID}" 3
    1
    bootstrap 集群的 bootstrap Ignition 内容。
    2
    作为字符串的 SSH RSA 公钥文件。
    3
    资源名称使用的基本名称 ; 这通常是集群的基础架构 ID。

您可以使用以下 Azure Resource Manager(ARM)模板来部署 OpenShift Container Platform 集群所需的 bootstrap 机器:
