Kubernetes Cluster on AWS
The Kubernetes Cluster template creates an infrastructure as code project in your favorite language and deploys a managed Kubernetes cluster to AWS. The architecture includes a VPC with public and private subnets and deploys an Amazon EKS cluster that provides a managed Kubernetes control plane. Kubernetes worker nodes are deployed on private subnets for improved security. Load balancers created by workloads deployed on the EKS cluster will be automatically created in the public subnets. The template generates a complete infrastructure as code program to give you a working project out of the box that you can customize easily and extend to suit your needs.
Using this template
To use this template to deploy your own managed Kubernetes cluster, make sure you’ve installed Pulumi and configured your AWS credentials, then create a new project using the template in your language of choice:
$ mkdir my-k8s-cluster && cd my-k8s-cluster $ pulumi new kubernetes-aws-typescript
$ mkdir my-k8s-cluster && cd my-k8s-cluster $ pulumi new kubernetes-aws-python
$ mkdir my-k8s-cluster && cd my-k8s-cluster $ pulumi new kubernetes-aws-go
$ mkdir my-k8s-cluster && cd my-k8s-cluster $ pulumi new kubernetes-aws-csharp
$ mkdir my-k8s-cluster && cd my-k8s-cluster $ pulumi new kubernetes-aws-yaml
Follow the prompts to complete the new-project wizard. When it’s done, you’ll have a complete Pulumi project that’s ready to deploy and configured with the most common settings. Feel free to inspect the code in
Deploying the project
The template requires no additional configuration. Once the new project is created, you can deploy it immediately with
$ pulumi up
When the deployment completes, Pulumi exports the following stack output values:
- The cluster’s kubeconfig file which you can use with
kubectlto access and communicate with your clusters.
- The ID for the VPC that your cluster is running in.
Output values like these are useful in many ways, most commonly as inputs for other stacks or related cloud resources.
Customizing the project
Projects created with the Kubernetes template expose the following configuration settings:
- The minimum number of nodes to allow in the cluster. Defaults to
- The maximum number of nodes to allow in the cluster. Defaults to
- The desired number of nodes in the cluster. Defaults to
- The EC2 instance type to use for the nodes. Defaults to
- The network CIDR to use for the VPC. Defaults to
All of these settings are optional and may be adjusted either by editing the stack configuration file directly (by default,
or by changing their values with
pulumi config set.
You can cleanly destroy the stack and all of its infrastructure with
$ pulumi destroy
