So, Karpenter has made another big step towards the release, and in version 0.32 it has moved from Alpha to Beta. Let’s take a quick look at the changes – and they are quite significant – and then upgrade to EKS from Karpneter Terraform module and Karpenter Helm chart. The process of installing Karpenter was… Read More »
So, we have a deployed Kubernetes cluster – see the Terraform: Creating EKS, Part 1 – VPCs, Subnets, and Endpoints series. And we have a GitHub Actions workflow to deploy it – see GitHub Actions: Deploying Dev/Prod environments with Terraform. It’s time to start deploying our backend to Kubernetes. Here we will use GitHub Actions… Read More »
With the data “terraform_remote_state” we can get the outputs of one project to use in another. For example, our AWS VPC is created separately from AWS EKS (although in the series Terraform: Building EKS, part 1 – VPC, Subnets and Endpoints VPCs were created as part of a cluster, but then I separated them). So,… Read More »
Now that we have Terraform code ready to deploy an AWS Elastic Kubernetes Service cluster (see Terraform: Building EKS, part 1 – VPC, Subnets and Endpoints and subsequent parts), it’s time to think about automation, that is, creating pipelines in CI/CD that would create new environments for testing features, or deploy updates to the Dev/Prod… Read More »
The last, fourth part, in which we will install the rest of the controllers and add a couple of useful little things. All the parts: Terraform: building EKS, part 1 – VPC, Subnets and Endpoints Terraform: building EKS, part 2 – an EKS cluster, WorkerNodes, and IAM Terraform: building EKS, part 3 – Karpenter… Read More »
This is the third part of deploying an AWS Elastic Kubernetes Service cluster with Terraform, in which we will add Karpenter to our cluster. I’ve decided to post this separately because it’s quite a long post. And in the next and final (hopefully!), the fourth part, we will add the rest – all kinds of… Read More »
We continue the topic of deploying an AWS Elastic Kubernetes Service cluster using Terraform. In the first part, we prepared an AWS VPC. In this part, we’ll deploy the EKS cluster itself, and will configure AIM for it, and in the next parts, we’ll install Karpenter and the rest of the controllers. All the… Read More »
So, now that we’ve been reminded a bit about Terraform’s data types and loops, it’s time to start building something real. The first thing we will deploy with Terraform is the AWS Elastic Kubernetes Service cluster and all the resources associated with it because now it is done with AWS CDK, and in addition… Read More »
In the previous post, we got an overview of the Terraform data types – Terraform: introduction to data types – primitives and complex. Now let’s see how these types can be used in loops. Terraform supports three types of cycles: count: the simplest, used with a given number or with a function length(); uses indexes from… Read More »
In this post, we will take a brief look at the data types that we can use in Terraform to better understand the topic of the following post – Terraform: count, for_each, and for loops. Documentation – Type Constraints and Types and Values. We have the following types divided into groups: Primitive Types: string: sequence of Unicode… Read More »
