8.2. 创建使用外部 OIDC 身份提供程序进行身份验证的 Red Hat OpenShift Service on AWS 集群

流程

• 如果您使用 OIDC_ID、SUBNET_IDS 和 OPERATOR_ROLES_PREFIX 变量准备您的环境，您可以在创建集群时继续使用这些变量。例如，运行以下命令：

  $ rosa create cluster --hosted-cp --subnet-ids=$SUBNET_IDS \
     --oidc-config-id=$OIDC_ID --cluster-name=<cluster_name> \
     --operator-roles-prefix=$OPERATOR_ROLES_PREFIX \
     --external-auth-providers-enabled

• 如果您没有设置环境变量，请运行以下命令：

  $ rosa create cluster --cluster-name=<cluster_name> --sts --mode=auto \
      --hosted-cp --operator-roles-prefix <operator-role-prefix> \
      --oidc-config-id <ID-of-OIDC-configuration> \
      --external-auth-providers-enabled \
      --subnet-ids=<public-subnet-id>,<private-subnet-id>

验证

• 运行以下命令验证您的外部身份验证是否在集群详情中启用：

  $ rosa describe cluster --cluster=<cluster_name>
