Randomly Generating User Passwords Using Ansible

First, i would like to note that i have recently started using Ansible for configuration management. One of the things i need in my server environment is to implement a user password changing policy. Since the targets are numerous, i have to use randomly generated passwords for each host. Because passwords are sensitive, they should be generated in the encrypted form. Ansible documentation recommends using python passlib library and SHA512 hashing here.

With the following function passwords can be randomly generated in the form of strings that are 8 characters long and contain uppercase ascii characters, lowercase ascii characters and digits.

My aim is to create one playbook template for each host from the ansible hosts. On my own way getting ansible hosts can be achieved like this:

# ansible all -m ping |grep success |awk '{print $1}' |sort > server_list

And playbook templates can be created reading server_list file line by line (take note the randomly generated passwords):

That's it. Playbook templates can be run one by one:

# ansible-playbook <target_host>.yml

Or in a for loop:

# for yaml in $(ls *.yml); do ansible-playbook $yaml; done
