ansible-role-linux-gluster's Issues

Could replace the need to supply hacluster password

I created a role similar and used the below to then not require passing the hacluster password as a var.

- name: Create random password
  ansible.builtin.set_fact:
    ha_userpass: "{{ lookup('ansible.builtin.password', '/dev/null', seed=ansible_date_time.time) }}"

- name: Change hacluster user password
  ansible.builtin.user:
    name: hacluster
    update_password: always
    password: "{{ ha_userpass | password_hash('sha512') }}"
