ack-ram-tool是容器服務 Kubernetes 版為輔助您管理集群RAM和RBAC權限提供的命令行工具。當用戶離職或權限需要變更時，通過ack-ram-tool工具您可以及時清理集群中已刪除用戶的權限，避免安全風險。

步驟一：安裝配置ack-ram-tool

  1. 執行以下命令，根據不同操作系統選擇安裝配置ack-ram-tool。

    展開查看Darwin_arm64系統的ack-ram-tool安裝配置

    cd /tmp
wget https://ack-ram-tool.oss-cn-hangzhou.aliyuncs.com/dist/v0.18.0/ack-ram-tool_0.18.0_Darwin_arm64.tar.gz
tar zxvf ack-ram-tool_0.18.0_Darwin_arm64.tar.gz
cp ack-ram-tool /usr/local/bin
ack-ram-tool version

    展開查看Darwin_x86_64系統的ack-ram-tool安裝配置

    cd /tmp
wget https://ack-ram-tool.oss-cn-hangzhou.aliyuncs.com/dist/v0.18.0/ack-ram-tool_0.18.0_Darwin_x86_64.tar.gz
tar zxvf ack-ram-tool_0.18.0_Darwin_x86_64.tar.gz
cp ack-ram-tool /usr/local/bin
ack-ram-tool version

    展開查看Linux_arm64系統的ack-ram-tool安裝配置

    cd /tmp
wget https://ack-ram-tool.oss-cn-hangzhou.aliyuncs.com/dist/v0.18.0/ack-ram-tool_0.18.0_Linux_arm64.tar.gz 
tar zxvf ack-ram-tool_0.18.0_Linux_arm64.tar.gz
cp ack-ram-tool /usr/local/bin
ack-ram-tool version

    展開查看Linux_x86_64系統的ack-ram-tool安裝配置

    cd /tmp
wget https://ack-ram-tool.oss-cn-hangzhou.aliyuncs.com/dist/v0.18.0/ack-ram-tool_0.18.0_Linux_x86_64.tar.gz
tar zxvf ack-ram-tool_0.18.0_Linux_x86_64.tar.gz
cp ack-ram-tool /usr/local/bin
ack-ram-tool version

  2. 通過以下任一方式配置ack-ram-tool所需的訪問憑證。

    • 自動從如下環境變量中讀取憑證信息。

      • ALIBABA_CLOUD_ACCESS_KEY_ID

      • ALIBABA_CLOUD_ACCESS_KEY_SECRET

      • ALIBABA_CLOUD_SECURITY_TOKEN，關于如何獲取SECURITY_TOKEN，請參見什么是STS。

    • 從aliyun CLI配置文件~/.aliyun/config.json中讀取憑證信息。關于配置方法，請參見配置憑證。

步驟二：配置ack-ram-tool訪問憑證所需的權限

ack-ram-tool使用的訪問憑證需要擁有RAM權限和集群的RBAC權限。

  1. 為RAM用戶授予如下權限。具體操作，請參見為RAM用戶授權。

    {
  "Version": "1",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "cs:*"
      ],
      "Resource": "*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "ram:ListUsers",
        "ram:ListRoles"
      ],
      "Resource": "*"
    }
  ]
}

  2. 為RAM用戶授予集群的RBAC管理員權限。

    1. 登錄容器服務管理控制臺，在左側導航欄選擇授權管理。

    2. 在授權管理頁面，單擊RAM 用戶頁簽，找到待添加的RAM用戶，單擊右側的管理權限，進入權限管理頁面。

    3. 單擊添加權限，選擇集群和命名空間，選擇權限管理為管理員的權限，然后單擊提交授權。

步驟三：查詢集群內指定RAM用戶的RBAC Binding

您可以通過ack-ram-tool rbac scan-user-permissions命令，查詢目標集群內指定RAM用戶的RBAC Binding信息。

僅查詢已刪除的RAM用戶和角色的RBAC Binding

執行以下命令，查看集群內已刪除的RAM用戶和角色的RBAC Binding信息。

ack-ram-tool rbac scan-user-permissions -c <集群ID>

步驟四：清理集群內指定RAM用戶或RAM角色的RBAC Binding并清除KubeConfig權限

您可以通過ack-ram-tool rbac cleanup-user-permissions命令，清理目標集群內指定RAM用戶或RAM角色的RBAC Binding以及清除該用戶的KubeConfig。

重要

  • 當日志中出現this user has been active in the past 7 days時，表明目標RAM用戶或RAM角色最近7天內有集群訪問記錄，請謹慎操作。

  • 執行清理操作前，ack-ram-tool工具會在當前目錄下以集群ID命名的文件夾中備份待刪除的Binding原始JSON文件。

清理RAM用戶或RAM角色在單個集群中的權限

執行以下命令，清理指定RAM用戶或RAM角色在單個集群中的權限。

以下命令行中的<UID>，您可以通過ack-ram-tool rbac scan-user-permissions -c <集群ID>命令獲取。

ack-ram-tool rbac cleanup-user-permissions -c <集群ID> -u <UID>
