In alternative, authenticate with AWS by running aws configure in your terminal. When prompted, enter your AWS Access Key ID, Secret Access Key, region and output format.

$ aws configure

AWS Secret Access Key [None]: <YOUR_AWS_SECRET_ACCESS_KEY>
Default region name [None]: <YOUR_AWS_REGION>
Default output format [None]: json

2. Create a key-pair named terraform-key and put into root folder

├── Makefile
.
.
.
├── provision
│   ├── terraform
│   └── vagrant
.
.
├──  terraform-key.pem
.
.

3. Download Terraform

• Follow installation guide on https://www.terraform.io/downloads.html to install Terraform

• Vagrant - Follow installation guide on https://www.vagrantup.com/docs/installation/index.html to install Vagrant

Step 1 - Start Kubernetes Vagrant cluster

make vagrant-start

Step 2 - Try Kubernetes Cluster
