Terraform template for kubernetes cluster

tf-aws-kubernetes

This is a PoC for using Terraform to build and deploy a Kubernetes cluster to an AWS VPC.

Currently this is a PoC, and proper security measures are not implemented.

Repeat after me: not for production use

Things you will need

• An Amazon Web Services account
• Potentially a few $ (this demo spawns several t2.small / m3.mediums)
• Terraform

Create a keypair in AWS

• There's plenty of ways to do this. Remember your keypair name.

Create your tfvars file

$ cp terraform.tfvars.tmpl terraform.tfvars

This file serves as your main config for your AWS keys etc. Use your keypair name here. Also make sure to use your IP CIDR for allowed_network, otherwise you won't be able to connect to the cluster.

Build the cluster

$ terraform apply

Create a tunnel for kubectl

$ $(terraform output create-tunnel)

Check your nodes

$ kubectl get nodes

NAME         LABELS                              STATUS
10.0.0.110   kubernetes.io/hostname=10.0.0.110   Ready
10.0.0.16    kubernetes.io/hostname=10.0.0.16    Ready
10.0.0.52    kubernetes.io/hostname=10.0.0.52    Ready

Open the UI in your browser

$ open $(terraform output ui-url)

SSH into the master

$ ssh core@$(terraform output master-ip)
