Vultr Firewalling with Ansible

2018-03-19 Sysadmin Ansible Vultr

This is the second part of a post series What’s new in Ansible 2.5. In the previous post we learned the basic steps to deploy a server on Vultr. In this follow up post, you will see how we can secure our server. This post was written in 2018 for Ansible 2.5, when the Vultr modules shipped with Ansible itself as vr_*.
