I would like to use ansible to roll out updates on servers I have running in a private openstack cloud. However I would like to do so without copying an ssh key into these servers. Instead I want to set my openstack password (as that's all I need to ssh into an instance from my company machines) as variables with some vars_prompt and then have ansible use those to ssh into my instances and run tasks.
How would I do this?
Sidenote: I feel like this post might be a duplicate based on how general this question is, so I will delete it if there is another post solving this issue.
You're overcomplicating it. ansible_password can be set on those hosts in your inventory (preferably using ansible vault with host_vars/group_vars dirs so the passwords aren't sitting there in cleartext). Then just run ansible-playbook with --ask-vault-pass and you're good to go.
