4.11.10. 在 AWS 中创建安全组和角色

download PDF

您必须在 Amazon Web Services (AWS) 中创建安全组和角色，供您的 OpenShift Container Platform 集群使用。

您可以使用提供的 CloudFormation 模板和自定义参数文件来创建 AWS 资源堆栈。堆栈代表 OpenShift Container Platform 集群所需的安全组和角色。

注意

如果不使用提供的 CloudFormation 模板来创建 AWS 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

  • 已配置了一个 AWS 帐户。
  • 您可以通过运行 aws configure，将 AWS 密钥和区域添加到本地 AWS 配置集中。
  • 已为集群生成 Ignition 配置文件。
  • 您在 AWS 中创建并配置了 VPC 及相关子网。

流程

  1. 创建一个 JSON 文件，其包含模板所需的参数值： 

    [
  {
    "ParameterKey": "InfrastructureName", 1
    "ParameterValue": "mycluster-<random_string>" 2
  },
  {
    "ParameterKey": "VpcCidr", 3
    "ParameterValue": "10.0.0.0/16" 4
  },
  {
    "ParameterKey": "PrivateSubnets", 5
    "ParameterValue": "subnet-<random_string>" 6
  },
  {
    "ParameterKey": "VpcId", 7
    "ParameterValue": "vpc-<random_string>" 8
  }
]
    1
    您的 Ignition 配置文件中为集群编码的集群基础架构名称。
    2
    指定从 Ignition 配置文件元数据中提取的基础架构名称，其格式为 <cluster-name>-<random-string>。
    3
    VPC 的 CIDR 块。
    4
    指定以 x.x.x.x/16-24 格式定义的用于 VPC 的 CIDR 地址块。
    5
    为 VPC 创建的专用子网。
    6
    指定 VPC 的 CloudFormation 模板输出的 PrivateSubnetIds 值。
    7
    为集群创建的 VPC。
    8
    指定 VPC 的 CloudFormation 模板输出的 VpcId 值。
  2. 复制本主题的安全对象的 CloudFormation 模板部分中的模板，并将它以 YAML 文件形式保存到计算机上。此模板描述了集群所需的安全组和角色。

  3. 启动 CloudFormation 模板，以创建代表安全组和角色的 AWS 资源堆栈：

    重要

    您必须在一行内输入命令。 

    $ aws cloudformation create-stack --stack-name <name> 1
     --template-body file://<template>.yaml 2
     --parameters file://<parameters>.json 3
     --capabilities CAPABILITY_NAMED_IAM 4
    1
    <name> 是 CloudFormation 堆栈的名称，如 cluster-sec。如果您删除集群，则需要此堆栈的名称。
    2
    <template> 是您保存的 CloudFormation 模板 YAML 文件的相对路径和名称。
    3
    <parameters> 是 CloudFormation 参数 JSON 文件的相对路径和名称。
    4
    您必须明确声明 CAPABILITY_NAMED_IAM 功能，因为提供的模板会创建一些 AWS::IAM::Role 和 AWS::IAM::InstanceProfile 资源。

    输出示例

    arn:aws:cloudformation:us-east-1:269333783861:stack/cluster-sec/03bd4210-2ed7-11eb-6d7a-13fc0b61e9db

  4. 确认模板组件已存在： 

    $ aws cloudformation describe-stacks --stack-name <name>

    在 StackStatus 显示 CREATE_COMPLETE 后，输出会显示以下参数的值。您必须将这些参数值提供给您在创建集群时要运行的其他 CloudFormation 模板：

    MasterSecurityGroupId

    Master 安全组 ID

    WorkerSecurityGroupId

    worker 安全组 ID

    MasterInstanceProfile

    Master IAM 实例配置集

    WorkerInstanceProfile

    worker IAM 实例配置集

4.11.10.1. 安全对象的 CloudFormation 模板

您可以使用以下 CloudFormation 模板来部署 OpenShift Container Platform 集群所需的安全对象。
