Ansible: To use the 'ssh' connection type with passwords, you must install the sshpass program"

Recently I created new roles called spd in my existing project. While other script works fine in the setup. This newly created fails. Please point me to what is going wrong here

ansible/roles
      spd
        tasks
        templates
        defaults

deploy-spd.yml

 - hosts:
   roles:
     - spd

inventory file

[kube-master]
kubernetes-master-1 ansible_host=10.20.0.225 ansible_user=centos ansible_become=true
kubernetes-master-2 ansible_host=10.20.0.226 ansible_user=centos ansible_become=true
kubernetes-master-3 ansible_host=10.20.0.227 ansible_user=centos ansible_become=true

Failure

Solution

The issue was because of use of attribute ansible_password in /defaults/main.yml. I have maintained lots of variables in this file to be used by script along with attribute ansible_password.

- include_vars: "{{ role_path}}/defaults/main.yml"

The attribute ansible_password is reserved for use by Ansible. Now I changed the variable name to ansible_pass and it is working fine.
