Single Cluster Setup

Objective

This pattern deploys one production grade Amazon EKS cluster, without any Observability add-on.

Prerequisites:

Ensure that you have installed the following tools on your machine.

  1. aws cli
  2. kubectl
  3. cdk
  4. npm

Deploying

  1. Clone your forked repository
git clone https://github.com/aws-observability/cdk-aws-observability-accelerator.git
  1. Install the AWS CDK Toolkit globally on your machine using
npm install -g aws-cdk

  1. Install project dependencies by running npm install in the main folder of this cloned repository

  2. Once all pre-requisites are set you are ready to deploy the pipeline. Run the following command from the root of this repository to deploy the pipeline stack:

make build
make pattern single-new-eks-cluster deploy

Verify the resources

Run update-kubeconfig command. You should be able to get the command from CDK output message.

aws eks update-kubeconfig --name single-new-eks-observability-accelerator --region <your region> --role-arn arn:aws:iam::xxxxxxxxx:role/single-new-eks-observabil-singleneweksobservabilit-5NW0A5AUXVS9

Let’s verify the resources created by steps above.

kubectl get nodes -o wide
Output:

NAME                                            STATUS   ROLES    AGE     VERSION               INTERNAL-IP    EXTERNAL-IP   OS-IMAGE         KERNEL-VERSION                  CONTAINER-RUNTIME
ip-10-0-157-151.eu-central-1.compute.internal   Ready    <none>   9m19s   v1.25.9-eks-0a21954   10.0.157.151   <none>        Amazon Linux 2   5.10.179-168.710.amzn2.x86_64   containerd://1.6.19

Next, lets verify the namespaces in the cluster:

kubectl get ns # Output shows all namespace

Output:

NAME                       STATUS   AGE
cert-manager               Active   7m8s
default                    Active   13m
external-secrets           Active   7m9s
kube-node-lease            Active   13m
kube-public                Active   13m
kube-system                Active   13m
prometheus-node-exporter   Active   7m9s

Teardown

You can teardown the whole CDK stack with the following command:

make pattern single-new-eks-cluster destroy

aws
