Deploy Rundeck on AWS EKS

Deploy Rundeck on AWS EKS

Amazon Elastic Kubernetes Service (Amazon EKS) is a fully-managed Kubernetes service that simplifies the process of building, securing, operating, and maintaining Kubernetes clusters on AWS. Amazon EKS automatically manages the Kubernetes nodes, containers, application availability and stored cluster data.
Deploying Rundeck on EKS takes advantage of Kubernetes capabilities such as auto-scaling, portability and availability. This makes it a strong choice for cloud deployments. Consequently, it’s common to see Rundeck implemented on Kubernetes clusters.
This guide explains how to configure different tools that interact with the AWS EKS and how to deploy a basic Rundeck (or commercial Process Automation) deployment on an AWS EKS Cluster.



  • A valid AWS account with sufficient access rights to create EKS clusters.
  • AWS CLI, a tool to interact with the AWS resources. Check the most recent version and instructions for installing it for your OS system hereopen in new window.
  • K9S, a tool for monitoring and interacting Kubernetes pods easily, recent version and installation instructions hereopen in new window.


  • Kubectl, the command line tool for working with Kubernetes clusters. Find installation instructions hereopen in new window.
  • EKS CTL, the command line tool for working with EKS clusters that automates many individual tasks. Find installation instructions hereopen in new window.
  • K9S, for monitoring the EKS cluster. This is optional but useful. Learn how to install it on your operating system by visiting thisopen in new window page.

Environmental Setup

Configure the AWS CLI tool with the following command

aws configure

When prompted, provide the AWS access and secret key.

Create the EKS cluster

EKS CLI is linked to AWS CLI. If AWS CLI was configured successfully in the previous step, create an EKS cluster with the following command.

eksctl create cluster --name oss-test-cluster --version 1.23 --region eu-north-1 --nodegroup-name test-workers --node-type t3.xlarge --nodes 3 --nodes-min 1 --nodes-max 4 --managed

Included parameters:
--name: The cluster name.
--version: The Kubernetes version. Where possible, use the latest version.
--region: AWS region where the cluster is deployed. The example uses eu-north-1 (Stockholm).
--nodegroup-name: The node group name. One or more Amazon EC2 instances deployed in an Amazon EC2 Auto Scaling group are referred to as a node group.
--node-type: C2 image type. It is crucial to pick a type with enough resources to run.
--nodes: The number of worker nodes (node groups).
--nodes-mi: Minimum number of workers (node groups).
--manage: Creates managed nodes to use AWS EC2 instances-based nodes, managed nodes are provisioned Amazon EC2 machines that offer Auto Scaling capabilities that are managed by Amazon EKS.

Configure kubectl to interact with the AWS EKS cluster

Enter the following AWS CLI command:

aws eks update-kubeconfig --region eu-north-1 --name oss-test-cluster

Creating the Rundeck namespace

To avoid interfering with other services, best practice is to create a different namespace than the default namespace. This example used the bangarang namespace for the deployment.

Create a bangarang namespace:

kubectl create namespace bangarang

Set the custom namespace as the default namespace

Set the bangarang namespace as the kubectl default:

kubectl config set-context --current --namespace=bangarang

This should be reflected by oss-test-cluster (bangarang namespace) using k9s


Deploying the Rundeck service

Create a text file named rundeck-svc.yaml:

apiVersion: v1
kind: Service
 name: rundeck-svc
   env: dev
 type: LoadBalancer
 - port: 4440
   env: dev

Deploy the service using the .yaml file:

kubectl apply -f rundeck-svc.yaml

Check service availability:

kubectl get service

Result should look like this:

Note: The "EXTERNAL-IP" column is the Service URL for the Rundeck deployment. Copy it for use in the next step.

Deploying Rundeck to EKS

Create a text file named rundeck-deployment.yaml:

apiVersion: apps/v1
kind: Deployment
 name: rundeck
   env: dev
 replicas: 1
     env: dev
       env: dev
     - name: rundeck
       image: rundeck/rundeck:4.8.0
       - name: RUNDECK_GRAILS_URL
         value: "http://service_url:4440"
       - containerPort: 4440

Note: http://service_url:4440 is the URL taken from the service URL. Use this URL to access the Rundeck instance.

Deploy Rundeck in the EKS:

kubectl apply -f rundeck-deployment.yaml

The deployment should look as follows in k9:
Rundeck is available via the service's external URL.


To uninstall the Rundeck deployment use:

kubectl delete deployment rundeck-deployment

Destroy the Service with:

kubectl delete service rundeck-svc
