Playbook example for getting remote host credentials from hashicorp vault

Assume the vault already up and running on https://127.0.0.1:8200

Two remote hosts with IP Address 172.20.20.100 and 172.20.20.101

The playbook will retrieve credentials from vault the create user in remote machines. We will user TLS mechanism to connect to vault.

Because this playbook using username and password to connect to machine, instead of ssh-copy-id mechanism, we need to install sshpass first.

Additional variables to be exported for make this playbook run, due to self-signed certificate and sshpass:

   export ANSIBLE_HOST_KEY_CHECKING=False
   export VAULT_SKIP_VERIFY=true
