Add user_id attribute to backup response

Add user_id attribute to backup response

https://blueprints.launchpad.net/cinder/+spec/add-user-id-attribute-to-backup-response

This blueprint proposes to add user_id attribute to the response body of list backup with detail and show backup detail APIs.

Problem description

Currently, there is a user_id field in the backups table. These fields are very useful for admin to manage the backup file, but this is not returned in response body. So it is difficult to manage the resources under the project. If there are multiple users under one project, it is impossible to distinguish which user the backup file belongs to.

Use Cases

In large scale environment, lots of backups resources were created in system, that we can only see the project to which the backup file belongs, but we cannot know to which user the backup belongs.

Administrators would like the ability to identify the users that have created backups.

Proposed change

This spec proposes to add user_id attribute to the response body of list backup with detail and show backup detail APIs.

Add a new microverion API to add user_id attribute to the response body of list backup with detail and show backup detail APIs:

  • List backups with detail GET /v3/{project_id}/backups/detail

  • Show backup detail GET /v3/{project_id}/backups/{backup_id}

Alternatives

The admin/user could get user_id from the context as a log print, but it’s difficult to find it out easily, especially when the user wants to find a very old backup file.

REST API impact

Add a new microversion in Cinder API.

List backups with detail:

GET /v3/{project_id}/backups/detail
Response BODY:
{
    "backups": [{
        ...
        "user_id": "515ba0dd59f84f25a6a084a45d8d93b2"
    }]
}

Show backup detail:

GET /v3/{project_id}/backups/{backup_id}
Response BODY:
{
    "backups": [{
        ...
        "user_id": "515ba0dd59f84f25a6a084a45d8d93b2"
    }]
}

Calling this method shows a user_id for volume backup. It is intended for admins to use, which is used to display the user to which the backup file belongs, and controlled by BACKUP_ATTRIBUTES_POLICY.
