Impersonation
It is possible for users to impersonate different users (with proper authorization). For example, an admin may want to troubleshoot some issue as a different user with less privileges. This requires passing impersonation headers to the API request. The headers are:
- Impersonate-User: The username to act as.
- Impersonate-Group: This is a group name to act as and can be provided multiple times to set multiple groups. This is optional, and it requires Impersonate-User.
- Impersonate-Extra-(extra name): This is a dynamic header used to associate extra fields with the user. This is optional, and it requires Impersonate-User.
With kubectl, you pass --as and --as-group parameters.
