Amazon Elastic Kubernetes Service

Deploying to Amazon EKS
Amazon Elastic Kubernetes Service (Amazon EKS) makes it possible to deploy, manage, and scale containerized applications using Kubernetes on AWS.
Since Amazon EKS is based on the open-source tool Kubernetes, applications managed by Amazon EKS are compatible with applications managed by other Kubernetes environments.
Notice that Amazon also offer the Amazon Elastic Container Service (Amazon ECS).
Docker desktop
To demonstrate that it is possible to use the same kubectl client to deploy containers to a laptop or Amazon EKS consider this Docker desktop example.
No containers running
kutectl apply -f ./blog.yaml
The cluster is running
Accessing the Docker desktop cluster
Login to aws.amazon.com
AWS Management Console
aws cli
The aws command line tool is used to manage the Amazon Web Services cloud.

eksctl
eksctl is a simple CLI tool for creating clusters on Amazon EKS.

eksctl documentation on the AWS site
ekctl project on github
installing eksctl
No clusters
eksctl create cluster
BASH
1% eksctl create cluster \ 2--name blog-cluster
optional arguments:
--node-type t2.nano \
--nodes 2
using eskctl to create a cluster (node type t2.nano)
blog-cluster is being created
blog-cluster active
blog-cluster Elastic Cloud Compute (EC2) nodes created
~/neilhaddley/.kube/config file has been updated
kubectl apply
Using kubectl apply command to deploy containers
cluster workloads
kubectl get
Get information about blog-service
kubectl get service/blog-service | awk {'print $1" " $2 " " $4 " " $5'} | column -t
load balancer url
Accessing the Amazon EKS cluster
eksctl delete cluster
using ekctl delete to remove the cluster
BASH
1% eksctl delete cluster \
--name blog-cluster
eksctl delete cluster
The cluster has been deleted
kubectl config use-context
To switch back to using Docker Desktop
BASH
1% kubectl config use-context docker-desktop
switch back to docker-desktop
Deleting an AWS Access Key
Publishing AWS Access Keys is not a great idea.
This is how Keys are deleted.
Select the Delete link
Click the Deactivate button
Confirm the access key name and click the Delete button
The Access key has been deleted
