Required Permission for Using MRS

This section describes permission required for using MRS.

Permission

By default, the system provides user management permission and resource management permission. The user management permission is used to manage users, user groups, and their permissions. The resource management permission is used to manage user operations on cloud service resources.

Users with this permission have the full operation rights on MRS resources.

Two methods are available:

  • Add the Tenant Administrator permission to the user group.
  • Add the MRS Administrator, Server Administrator, and Tenant Guest permission to the user group.

MRS query permission

Users with this permission can:

  • View overview information about MRS.
  • Query MRS operation logs.
  • Query MRS cluster lists, including existing clusters, historical clusters, and task lists.
  • View cluster basic information and patch information.
  • View job lists and job details.

  • Query the alarm list.
  • Access the MRS Manager portal.
