# Ansible

## ansible-pull

ansible-pull comes with ansible installation. No additional installation is required.

**ansible-pull allows machine's to 'pull' ansible-playbooks from a git server & then run them locally.**

*No need to maintain a central server. So, practically no single point of failure if GitHub is used*

In a general ansible scenario,

![normal ansible scenario](/files/-MgdhA2QKXbq05d7nd59)

Here, ansible server centrally manages 4 machines. If one of the machine is unreachable for some reasons, ansible throws an error. But, what if you want your machine to be offline for a certain period of time? And only want them to run ansible-playbook in your specified time or time gaps?

Here comes ansible-pull

![typical ansible-pull scenario](/files/-Mge2Xg2zzlmkchOefx7)

Machines pull ansible-playbook from git server and run them locally, You can create cron jobs for specified users to have better control over ansible.
