awslabs-eks

This repository contains the infrastructure and code for a quick look and play with AWS EKS.

Ansible

Using ansible here to do the cloudformation orchestration. Just a test to see how it compares to other tools and whether its a decent alternative in CI/CD pipelines.

Tools

• make
• yamllint
• shellcheck
• mustache for bash (mo)
• aws cli
• eks tools

Configure

Install kubectl and other tools as per the getting started guide - https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html

Deploy

1. Set your aws environment.
2. Make deploy should create all the infrastructure, setup your local kubernetes config and and create the nginx app and dashboard.

AWS_DEFAULT_REGION=us-west-2 ENVIRONMENT=dev KEY_NAME=<yourkeyname> make deploy

export KUBECONFIG=$KUBECONFIG:~/.kube/config-<clusternamee>

Cluster Name and Environment are synonymous.

Sample App

Run a basic nginx container. Now part of make deploy but update nginx version and see rolling update in action.

kubectl apply -f nginx.yaml

Create the service to get an external ip.

kubectl apply -f nginx-service.yaml

Kubernetes Dashboard

kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep eks-admin | awk '{print $1}')

Start the kubectl proxy.

kubectl proxy

Open the following link with a web browser to access the dashboard endpoint: http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/

Commands

kubectl get services -o wide

kubectl get pods -l app=nginx

kubectl describe pod <podname>
