Unable to create a Kubernetes dashboard token

[roncemer]

SUMMARY

Unable to find any way to create a Kubernetes dashboard token. Typically with kubectl, this is done with the following command:

kubectl -n kubernetes-dashboard create token --duration=43200s admin-user

If you add -o yaml to this command, you get output similar to the following:

kind: TokenRequest
metadata:
  creationTimestamp: "2024-09-13T14:58:48Z"
  name: admin-user
  namespace: kubernetes-dashboard
spec:
  audiences:
  - https://kubernetes.default.svc
  boundObjectRef: null
  expirationSeconds: 43200
status:
  expirationTimestamp: "2024-09-14T02:58:48Z"
  token: <base64-encoded token here>

So I tried creating this task:

    - name: "Create a Kubernetes dashboard token"
      changed_when: false
      kubernetes.core.k8s:
        kubeconfig: "{{ kubeconfig }}"
        state: "present"
        force: true
        definition:
          apiVersion: authentication.k8s.io/v1
          kind: TokenRequest
          metadata:
            name: admin-user
            namespace: kubernetes-dashboard
          spec:
            audiences:
            - https://kubernetes.default.svc
            boundObjectRef: null
            expirationSeconds: 43200
      register: create_token_output

But it just generates the following error:

fatal: [localhost]: FAILED! => {"changed": false, "msg": "Failed to find exact match for authentication.k8s.io/v1.TokenRequest by [kind, name, singularName, shortNames]"}

STEPS TO REPRODUCE

Set the kubeconfig fact to the path to a valid kubeconfig file for the cluster, then run the following task.

    - name: "Create a Kubernetes dashboard token"
      changed_when: false
      kubernetes.core.k8s:
        kubeconfig: "{{ kubeconfig }}"
        state: "present"
        force: true
        definition:
          apiVersion: authentication.k8s.io/v1
          kind: TokenRequest
          metadata:
            name: admin-user

            boundObjectRef: null
            expirationSeconds: 43200
      register: create_token_output

EXPECTED RESULTS

Create and output the dashboard token.

ACTUAL RESULTS

Hi @roncemer,

Suppose you will apply the same definition with kubectl apply -f <file.yaml> you will have the same result.

It seems that the request of a service account token is not supported yet in kubernetes.core collections, you can create Feature request or make with requested feathere a PR by yourself with official kubernetes python client.
