Install Rancher 2 w/ Terraform & Ansible - Part #7 - Manage Your iptables Firewall with Ansible

In this tutorial we will cover using Docker and Ansible to install iptables on our remote Rancher 2 / Kubernetes host. By the end of this tutorial we will have: * Added a new third party role geerlingguy.firewall * Created a custom config applied only to our rancher-2-kubernetes-nodes group members To get the port requirements for Rancher 2 Nodes, Kubernetes Cluster Nodes, and some other suggested ports, we will need to refer to the installation reference. This may change between when I'm writing / recording this, and when you're following along. So don't follow this blindly.
