Users

User Resource​

The User resource (users.management.cattle.io) represents a user account in Rancher.

To get a description of the fields and structure of the User resource, run:

kubectl explain users.management.cattle.io

Creating a User​

Creating a local user is a two-step process: you must create the User resource, then provide a password via a Kubernetes Secret.

Only a user with sufficient permissions can create a User resource.

kubectl create -f -<<EOF
apiVersion: management.cattle.io/v3
kind: User
metadata:
 name: testuser     
displayName: "Test User"             
username: "testuser"
EOF

The user's password must be provided in a Secret object within the cattle-local-user-passwords namespace. The Rancher webhook will automatically hash the password and update the Secret.

info

Important: The Secret must have the same name as the metadata.name (and username) of the User resource. 

kubectl create -f -<<EOF
apiVersion: v1
kind: Secret
metadata:
 name: testuser
 namespace: cattle-local-user-passwords
type: Opaque
stringData:
 password: Pass1234567!
EOF

After the plaintext password is submitted, the Rancher-Webhook automatically hashes it, replacing the content of the Secret, ensuring that the plaintext password is never stored:

apiVersion: v1
data:
  password: 1c1Y4CdjlehGWFz26F414x2qoj4gch5L5OXsx35MAa8=
  salt: m8Co+CfMDo5XwVl0FqYzGcRIOTgRrwFSqW8yurh5DcE=
kind: Secret
metadata:
  annotations:
    cattle.io/password-hash: pbkdf2sha3512
  name: testuser
  namespace: cattle-local-user-passwords
  ownerReferences:
  - apiVersion: management.cattle.io/v3
    kind: User
    name: testuser
    uid: 663ffb4f-8178-46c8-85a3-337f4d5cbc2e
  uid: bade9f0a-b06f-4a77-9a39-4284dc2349c5
type: Opaque

Updating User's Password​

To change a user's password, use the PasswordChangeRequest resource, which handles secure password updates.

kubectl create  -f -<<EOF
apiVersion: ext.cattle.io/v1
kind: PasswordChangeRequest
spec:
  userID: "testuser"
  currentPassword: "Pass1234567!"
  newPassword: "NewPass1234567!"
EOF

Listing Users​

List all User resources in the cluster:

kubectl get users
NAME           AGE
testuser       3m54s
user-4n5ws     12m

Viewing a User​

View a specific User resource by name:

kubectl get user testuser
NAME           AGE
testuser       3m54s

Deleting a User​

Deleting a user will automatically delete the corresponding password Secret.

kubectl delete user testuser
user.management.cattle.io "testuser" deleted

Get a Current User's Information​

A client uses the SelfUser resource to retrieve information about the currently authenticated user without knowing their ID. The user ID is returned in the .status.userID field.

kubectl create -o jsonpath='{.status.userID}'  -f -<<EOF
apiVersion: ext.cattle.io/v1
kind: SelfUser
EOF

testuser

Refreshing a User's Group Membership​

Updates to user group memberships are triggered by the GroupMembershipRefreshRequest resource.

note

Group membership is only supported for external authentication providers.

For a Single User​

kubectl create -o jsonpath='{.status}'  -f -<<EOF
apiVersion: ext.cattle.io/v1
kind: GroupMembershipRefreshRequest
spec:
  userId: testuser
EOF

{
    "conditions": [
        {
            "lastTransitionTime": "2025-11-10T12:01:03Z",
            "message": "",
            "reason": "",
            "status": "True",
            "type": "UserRefreshInitiated"
        }
    ],
    "summary": "Completed"
}

For All Users​


kubectl create -o jsonpath='{.status}'  -f -<<EOF
apiVersion: ext.cattle.io/v1
kind: GroupMembershipRefreshRequest
spec:
   userId: "*"
EOF

{
    "conditions": [
        {
            "lastTransitionTime": "2025-11-10T12:01:59Z",
            "message": "",
            "reason": "",
            "status": "True",
            "type": "UserRefreshInitiated"
        }
    ],
    "summary": "Completed"
}
