Deploy the tyk-pump helm chart on AWS EKS
TypeScriptTo deploy the Tyk Pump Helm chart on AWS EKS, you'll need to complete several steps:
- Create an EKS cluster on Amazon Web Services (AWS).
- Configure Kubectl to communicate with your EKS cluster.
- Use Helm to deploy the Tyk Pump chart to your EKS cluster.
Let's break these steps down into a Pulumi program written in TypeScript.
Step 1: Create an EKS Cluster
To start, you will need to create an EKS cluster. The
@pulumi/eks
package is a Pulumi component that simplifies creating EKS clusters.First, we'll need to import the necessary Pulumi packages and then define a new EKS cluster. We will use the minimal configuration for demonstration purposes. In a real-world scenario, you might need to configure additional settings such as VPC, subnets, IAM roles, etc.
Here's how you set up an EKS cluster in Pulumi:
import * as eks from "@pulumi/eks"; // Create an EKS cluster with the default configuration. const cluster = new eks.Cluster("tykPumpCluster"); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig;
Step 2: Configure Kubectl
To deploy the Helm chart, you'll need to have a
kubeconfig
file that allows you to connect to your EKS cluster. Pulumi generates this for you when it creates the cluster. Thekubeconfig
is exported at the end of the Pulumi program, and you can use it withkubectl
as well as with Helm.Step 3: Deploy Tyk Pump Helm Chart
With the EKS cluster in place and
kubectl
configured, you can now deploy the Tyk Pump Helm chart. Pulumi has aChart
resource within the@pulumi/kubernetes
package that enables you to deploy Helm charts.Here's how to deploy the Tyk Pump Helm chart:
import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes provider instance that uses our EKS cluster's kubeconfig. const provider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig, }); // Deploy the Tyk Pump Helm chart. const tykPumpChart = new k8s.helm.v3.Chart("tyk-pump", { repo: "tyk-helm", chart: "tyk-pump", }, { provider });
For Helm to find and install the Tyk Pump chart, you need to provide the name of the Helm repository. If the Tyk Pump chart is in a custom repository, you should add that repository to the Helm CLI and reference it in your program.
Full Pulumi Program
Now, let's combine all the steps into a complete Pulumi TypeScript program:
import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an EKS cluster. const cluster = new eks.Cluster("tykPumpCluster"); // Step 2: Configure k8s provider to use the generated kubeconfig from the EKS cluster. const provider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig, }); // Step 3: Deploy the Tyk Pump Helm chart. const tykPumpChart = new k8s.helm.v3.Chart("tyk-pump", { repo: "tyk-helm", chart: "tyk-pump", }, { provider }); // Export the EKS cluster's kubeconfig so you can connect to your cluster with kubectl. export const kubeconfig = cluster.kubeconfig;
To use this program:
- Set up Pulumi with AWS: Ensure you have an AWS account configured with the necessary credentials and Pulumi installed and set up.
- Save the above code to a file named
index.ts
. - Run
pulumi up
to create the resources defined in the program. Pulumi will provision the EKS cluster and deploy the Tyk Pump Helm chart to it.
Remember to reference the EKS Cluster documentation and Helm Chart documentation for a better understanding and further configuration of your resources.
