Create a CoreOS account here : https://account.coreos.com/login
You can use your Gmail to sign in and get a free license for 10 nodes.

Create a t2 small ec2 ubuntu 64 bit machine and login

$sudo apt-get update

$sudo apt install gnupg2
$sudo apt install unzip
$sudo apt install awscli

$export PATH=$(pwd)/tectonic-installer/linux:$PATH
$terraform init platforms/aws

$mkdir -p build/${CLUSTER}
$export CLUSTER=my-cluster
$cp examples/terraform.tfvars.aws build/${CLUSTER}/terraform.tfvars

vi build/${CLUSTER}/terraform.tfvars

Make sure you set these properties

tectonic_aws_region = "ap-south-1"
tectonic_base_domain = "yourdomain.com" // your base domain from Rout53
tectonic_license_path = "/home/ubuntu/license.txt"
tectonic_pull_secret_path = "/home/ubuntu/pullsecret.json"
tectonic_cluster_name = "test" // your cluster name

Note: Pull secret and license files are available in your core os account.

$aws configure

AWS Secret Access Key :Enter Secret Key here
Default region name: ap-south-1
Default output format: Leave Empty

$export TF_VAR_tectonic_admin_email="your google email used for CoreOS"
$export TF_VAR_tectonic_admin_password="your password"

$ terraform plan -var-file=build/${CLUSTER}/terraform.tfvars platforms/aws
$ terraform apply -var-file=build/${CLUSTER}/terraform.tfvars platforms/aws

After few minutes ( 5 to 10 ) , cluster will be up and you can access it here :
https://test.yourdomain.com

The username password is same as your CoreOS account.

Accessing Cluster with kubectl commandline :

Now download kubectl-config and kubectl files from your cluster.

$ chmod +x kubectl
$ mv kubectl /usr/local/bin/kubectl
$ mkdir -p ~/.kube/ # create the directory
$ cp path/to/file/kubectl-config-test $HOME/.kube/config # rename the file and copy it into the directory
$ export KUBECONFIG=$HOME/.kube/config

Try to get nodes and see if you can see the nodes.

$ kubectl get nodes

In next entry, we will see how to Deploy a simple Application with kubectl commandline
