Amazon EKS Cluster: Hello World!

This example deploys an EKS Kubernetes cluster with query node

Deploying the App

To deploy your infrastructure, follow the below steps.

Prerequisites

1. Install Pulumi
2. Install Node.js
3. Install a package manager for Node.js, such as npm or Yarn.
4. Configure AWS Credentials
5. Optional (for debugging): Install kubectl

Steps

After cloning this repo, from this working directory, run these commands:

1. Install the required Node.js packages:

This installs the dependent packages needed for our Pulumi program.

   $ npm install

1. Create a new stack, which is an isolated deployment target for this example:

This will initialize the Pulumi program in TypeScript.

   $ pulumi stack init

1. Set the required AWS configuration variables in Pulumi.<stack>.yaml

2. Create a .env file in this directory and set the database and other variables in it

3. Stand up the EKS cluster:

Running pulumi up -y will deploy the EKS cluster. Note, provisioning a new EKS cluster takes between 10-15 minutes.

1. Access the Kubernetes Cluster using kubectl

To access your new Kubernetes cluster using kubectl, we need to set up the kubeconfig file and download kubectl. We can leverage the Pulumi stack output in the CLI, as Pulumi facilitates exporting these objects for us.

   $ pulumi stack output kubeconfig --show-secrets > kubeconfig
   $ export KUBECONFIG=$PWD/kubeconfig
   $ kubectl get nodes

We can also use the stack output to query the cluster for our newly created Deployment:

   $ kubectl get deployment $(pulumi stack output deploymentName) --namespace=$(pulumi stack output namespaceName)
   $ kubectl get service $(pulumi stack output serviceName) --namespace=$(pulumi stack output namespaceName)

To get logs

   $ kubectl config set-context --current --namespace=$(pulumi stack output namespaceName)
   $ kubectl get pods
   $ kubectl logs <PODNAME> --all-containers

To see complete pulumi stack output

   $ pulumi stack output

To execute a command

   $ kubectl exec --stdin --tty <PODNAME> -c colossus -- /bin/bash

1. Once you've finished experimenting, tear down your stack's resources by destroying and removing it:

   $ pulumi destroy --yes
   $ pulumi stack rm --yes
