Working with ansible-vault

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.

Certificate CA Validation

The easy way

To validate a certificate agains a certificate authority you just have to run

openssl verify -trusted ca_root.pem -untrusted intermediate_ca.pem certificate.pem

You'll see a 'OK' message at the end of the output

using Ansible command line:

ansible-playbook --connection=local 127.0.0.1 playbook.yml

using inventory:

127.0.0.1 ansible_connection=local
