Code to create a Docker + Rancher + Cattle cluster with Ansible and Terraform

Intro to Docker orchestration with Rancher using Terraform & Ansible for deployment

Description

• Aids in setup of Docker + Rancher on Digital Ocean with Terraform/Ansible
• Also contains nodejs-echo-hostname which helps to illustrate Rancher load balancing

Setup

• Create a Digital Ocean API token
• set an environment variable for the token

export DIGITALOCEAN_TOKEN="ABDC123..."

• Install ansible

• Install terraform

• To create your VMs, from ./terraform run

terraform apply

• The script updates ansible inventory with the new IPs

• Visit http://IP_OF_YOUR_DOCKER_0_BOX:8080/ Infrastructure > Add Hosts

• Run

ansible all -u root -a "COMMAND_RANCHER_GIVES_YOU"

NOTE: add a curl to grab this and automatically insert into ansible cmd

Done!

You should now have a multi-node Rancher + Cattle + Docker cluster going that you can now run containers on
