# 约束与限制
- 通过ccictl操作CCI资源暂不支持IAM 5.0(Landingzone)场景。
- 目前ccictl仅支持以下命令范围和资源范围: 支持命令：create, set, explain, get, edit, delete, rollout, describe, logs, exec, apply, api-resources, api-versions, config, version, options
  支持资源及命令如下：

- 进行命名空间级资源操作，如果未显示指定"--namespace"选项时，ccictl会默认指定"default"命名空间。新用户首次使用CCI，云服务不会自动创建"default"命名空间。
