Quickstart examples for Rancher

Summary

This repo contains scripts that will allow you to quickly deploy instances for use during a Rancher Rodeo.

The contents aren't intended for production but are here to get you up and running quickly during the rodeo session, either with DO, AWS, or Vagrant.

DO / AWS Quickstart

The do folder and aws folder each contain Terraform scripts to stand up an instance for the Rancher Server and a configurable number of instances for the Kubernetes nodes. By default this number is set to one but can be set with count_agent_all_nodes in the terraform.tfvars file.

How to use

• Clone this repository and go into the corresponding subfolder for your provider
• Move the file terraform.tfvars.example to terraform.tfvars and edit (see inline explanation)
• Run terraform init
• Run terraform apply

When provisioning has finished you will have instances that you can use to deploy Rancher Server and Kubernetes.

How to Remove

To remove the VMs that have been deployed run terraform destroy --force

Please be aware that you will be responsible for the usage charges with Digital Ocean and Amazon Web Services

Vagrant Quickstart

The vagrant folder contains the configuration to deploy a single VM for the Rancher Server and one or more VMs for the Kubernetes cluster. By default this number is set to one but can be changed by adjusting count under node in config.yaml.

If you set rodeo to false in config.yaml the installation will provision a complete Rancher Server and Kubernetes cluster all at once. Use this to redeploy a Vagrant cluster quickly.

The prerequistes for this are vagrant and virtualbox, installed on the PC you intend to run it on, and 6GB free memory

How to Use

• Clone this repository and go into the vagrant subfolder
• Edit config.yaml to set any values for the installation
• Run vagrant up

When provisioning is finished the Rancher Server will be available via SSH at 172.22.101.101 and the nodes will be available on sequential IPs starting at 172.22.101.111. If you set rodeo to false, the Rancher Server UI will be available at https://172.22.101.101/.

How to Remove

To remove the VMs that have been deployed run vagrant destroy -f. The configuration uses linked clones, so if you want to destroy the origin instance, open the VirtualBox Manager and remove the base ubuntu-xenial instance left behind.
