Terraform cluster deployment

Overview

Terraform script for deploying a cluster to Digital Ocean and setting up helm

Add your digital ocean token to deployments/staging/cluster/variables.tf

Prerequisites

Install teraform

Step 1

• Deploy k8s cluster

make deploy

This will deploy a k8s cluster and download the kube_config

It also generates a input.tfvars.json file that is used in step 2

Step 2

• Setup k8s cluster

Ensure you have exported your pgp key to ./*/setup/secring.pgp

make setup

Validations

Run the following commands to validate everything has worked correctly

kubectl get pods --all-namespaces

See pods:

• tiller-deploy
• istio-citadel
• istio-pilot
• istio-ingressgateway

kubectl get serviceaccounts --all-namespaces

See service account:

• tiller

kubectl get namespaces

See new namespaces:

• istio-system
• go-apis

Step N

• Destroy k8s cluster

make destroy

Beware of Dragons

1. make setup needs to be ran twice, race condition between installing istio crds and installing istio
