I'm trying to install kubernetes cluster, deploy dashboard and generate a token for admin user in ansible, but when I put the command in the task I get an error.
I've tried to escape the quotes with no success, also tried to escape dollar sign with \$ with no success.
- name: 19/23 Get dashboard token for admin user
become: false
command: "{{ item }}"
register: output
with_items:
- kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk '{print $1}')
- debug: msg="{{ output.stdout_lines }}"
Here is the error output, I want to execute this command in ansible task and print then with debug to capture the token and save to a txt file later.

Use shell
module instead of command
. As you can see difference in the answer of this post
Similar to below ansible-playbook:
---
- hosts: local
tasks:
- name: get secret name
shell: 'kubectl -n kube-system get secret -o=name| grep admin-user'
register: secret
- name: get token for kubernetes-dashboard user
shell: "kubectl -n kube-system get {{ secret.stdout }} -o=jsonpath='{..token}'"
register: token
- debug:
var: token.stdout
