In case this command fails, you may want to make sure your credentials are set up correctly, as mentioned here.Ģ. Run the following command to check if eksctl can successfully access the AWS account and list any existing clusters: eksctl get cluster -region us-east-1 Follow the steps below to create a Kubernetes cluster.ġ. ![]() Creating a Kubernetes clusterĪssuming you have followed the steps in the prerequisites section, you should have eksctl installed. This is a really enthralling space, especially for folks interested in DevOps. Read more about the benefits of containerization and container orchestration with Kubernetes here. For this Kubernetes tutorial, let’s create a cluster on AWS. For instance, you can have your cluster on GCE, AWS, Azure, or any cloud provider. ![]() You can use Kubernetes anywhere for on-premise deployments or even hybrid clouds. You can easily scale up and scale down your services with Kubernetes. We have established why the world is moving towards containers, but who is going to manage these containers and how do you roll out a release? How do you run health checks against your services and get them back up if they are failing? Kubernetes automates all of this for you. Services don’t need to be intertwined with each other, and a microservices architecture works best with containerization. Benefits of containerization Enter KubernetesĮach app/service now runs in a container, so there can be a separation of concerns. Docker can be used as the container runtime. They are preferred over virtual machines (VMs) since they use operating system-level virtualization and are lighter than VMs. Containers provide you with a sustainable environment because your application now runs in a box (container) that includes all dependencies required by your app to run and is isolated from other applications running in other containers. It may be because the production environment has different versions of the libraries, a different operating system, different system dependencies, etc. Just import the Deploy with Amazon EKS and Kubernetes API collection by clicking on Run in Postman to follow this tutorial.ĭeploy with Amazon EKS and Kubernetes API Template A brief overview of containersĪre you familiar with the “ But it works on my machine” problem? A lot of times your application doesn’t perform as it does in your local environment. Here is a helpful Amazon EKS guide that has all of the prerequisites mentioned above and instructions to install them.Įxplore this blog post in an interactive format by using our companion template. Create your Amazon Cluster IAM role to access the cluster.Install kubectl, a command-line utility to work with Kubernetes clusters.Install eskctl,a command utility to interact and create the cluster on EKS.Install and configure AWS ALI to configure credentials.In addition you also need to do the following: Prerequisitesįamiliarity with REST APIs is a prerequisite. Note: We will be creating the Kubernetes cluster on AWS EKS, but you can also follow the tutorial with a cluster hosted on any other cloud providers or locally using Minikube. Accessing the Kubernetes API from Postman.Don’t fret if you aren’t familiar with Kubernetes and containerization, because we’ll go over each of the following: In this tutorial, we are going to use Postman Collections to learn Kubernetes and use its API to deploy an app on a Kubernetes cluster hosted on AWS. Kubernetes is an open source system that is useful for container orchestration. ![]()
