in-memory kubeconfig rather than file

[hassenius]

SUMMARY

Have a method to use non-file-based kubeconfig

ISSUE TYPE

Feature or documentation improvement if already possible

COMPONENT NAME

kubernetes.core.k8s

ADDITIONAL INFORMATION

In our case we store the relevant kubernetes auth information in an external secret store, so we can easily retrieve the content of a kubeconfig file which has all the relevant information to connect to the cluster.
It appears that the kubernetes.core.k8s component expects to find kubeconfig as a file: https://docs.ansible.com/ansible/latest/collections/kubernetes/core/k8s_module.html#parameter-kubeconfig
with no way to feed ca/client_cert/key in as direct values.

This means for us we'd need to save the relevant information to temporary files after retrieving them from external secret store.

@hassenius thanks for taking the time to report this new feature request.
As mentioned for now to connect to the cluster using kubeconfig you will need a file, but if you have the username, password and host information (or api_key) you can feed them directly to the kubernetes.core.k8s module.
As a workaround you can use the ansible.builtin.tempfile module to create the kubeconfig file.

e.g.

- name: Store kube/config in tempfile
  ansible.builtin.tempfile:
    state: file
  register: aks_kubeconfig_tmpfile
- name: Place kubeconfig onto filesystem temporarily
  copy: 
    content: "{{ azure_aks_cluster.kube_config }}"
    dest: "{{ aks_kubeconfig_tmpfile.path }}"
    mode: '0600'
- name: Get Cluster information
  kubernetes.core.k8s_info:
    kind: namespace
    kubeconfig: "{{ aks_kubeconfig_tmpfile.path }}"
