流程

1. 运行以下命令，获取集群 ID、特定于集群 Operator 角色的 Amazon 资源名称(ARN)和 OIDC 供应商的端点 URL：

   $ rosa describe cluster --cluster=<cluster_name>

   1

   列出集群 ID。

   2

   指定特定于集群 Operator 角色的 ARN。例如，在示例输出中，Machine Config Operator 所需的角色的 ARN 是 arn:aws:iam::<aws_account_id>:role/mycluster-x4q9-openshift-machine-api-aws-cloud-credentials。

   3

   显示特定于集群的 OIDC 供应商的端点 URL。

   重要

   删除集群后，您需要集群 ID 来使用 ROSA CLI 删除特定于集群的 STS 资源。

2. 使用 OpenShift Cluster Manager 或 ROSA CLI 删除集群：

   • 使用 OpenShift Cluster Manager 删除集群：

     1. 导航到 OpenShift Cluster Manager。
     2. 点击集群 旁边的 Options 菜单并选择 Delete cluster。
     3. 在提示符处键入集群名称并点 Delete。

   • 使用 ROSA CLI 删除集群：

     1. 运行以下命令，将 &lt ;cluster_name > 替换为集群的名称或 ID：

        $ rosa delete cluster --cluster=<cluster_name> --watch

        重要

        在删除 Operator 角色和 OIDC 供应商前，您必须等待集群删除完成。

3. 运行以下命令来删除特定于集群的 Operator IAM 角色：

   • 对于没有共享虚拟私有云(VPC)的集群：

     $ rosa delete operator-roles --prefix <operator_role_prefix>

   • 对于具有共享 VPC 的集群：

     $ rosa delete operator-roles --prefix <operator_role_prefix> --delete-hosted-shared-vpc-policies

4. 运行以下命令来删除 OIDC 供应商：

   $ rosa delete oidc-provider --oidc-config-id <oidc_config_id>
