< p > Congratulations. You’ ve just contacted your nodes with Ansible. It’ s now time to read some
2012-03-09 04:50:12 +01:00
of the more real-world examples, and explore what you can do with different modules, as well
2012-03-09 05:06:07 +01:00
as the Ansible playbooks language. Ansible is not just about running commands, but you already
have a working infrastructure!< / p >
