Deploy the tyk-pump helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

To deploy the Tyk Pump Helm chart on Azure Kubernetes Service (AKS), you will need to perform several steps which include:

Set up an AKS cluster
Install Helm on your local machine or within an automation pipeline
Add the Tyk Helm repository
Update your Helm chart repository to ensure you have the latest charts
Deploy the Tyk Pump Helm chart to your AKS cluster

We will use Pulumi to set up the AKS cluster. Once the cluster is created, we'll either use Pulumi's automation API or manual commands to install the Helm chart onto the cluster. Given Pulumi's current capabilities, we can manage the Kubernetes cluster itself, but you may need to run Helm commands manually or by using Pulumi with external scripting to actually deploy the chart.

Below is a Pulumi program written in TypeScript that creates an AKS cluster. After the TypeScript program, I'll guide you through the process of deploying the Tyk Pump Helm chart onto this cluster.

import * as azure from "@pulumi/azure-native";
import * as pulumi from "@pulumi/pulumi";
import * as k8s from "@pulumi/kubernetes";

// Create an Azure Resource Group
const resourceGroup = new azure.resources.ResourceGroup("myResourceGroup", {
    location: "WestUS", // You can change the location to your preference
});

// Create an AKS cluster
const cluster = new azure.containerservice.ManagedCluster("myCluster", {
    resourceGroupName: resourceGroup.name,
    agentPoolProfiles: [{
        count: 1,
        mode: "System",
        name: "agentpool",
        vmSize: "Standard_DS2_v2",
        osType: "Linux",
    }],
    dnsPrefix: "myk8scluster",
    kubernetesVersion: "1.20.7", // This should be updated to the desired version
    enableRBAC: true,
    servicePrincipalProfile: {
        clientId: "service-principal-client-id", // Provide your service principal clientId
        secret: "service-principal-client-secret", // Provide your service principal client secret
    },
});

// Expose a KubeConfig Output for connecting to the AKS cluster
const creds = pulumi.all([cluster.name, resourceGroup.name]).apply(([clusterName, rgName]) => 
    azure.containerservice.listManagedClusterUserCredentials({
        resourceName: clusterName,
        resourceGroupName: rgName,
    }));

const kubeConfig = creds.kubeconfigs[0].value.apply(c => Buffer.from(c, 'base64').toString());

const clusterKubeConfig = new pulumi.ConfigMap("kubeConfig", {
    data: {"config": kubeConfig},
});

// Export the kubeconfig.
export const kubeConfigOutput = kubeConfig;

// Use the pulumi/kubernetes provider to connect to the AKS cluster
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: kubeConfig,
});

This Pulumi TypeScript program creates a new AKS cluster with the following resources:

ResourceGroup: A container that holds related resources for an Azure solution includes all created resources.
ManagedCluster: An instance of AKS where your managed Kubernetes services will be running.

After setting up the AKS cluster with Pulumi, you would typically install and configure kubectl with the generated kubeConfig to interact with your Kubernetes cluster and then use Helm to deploy the Tyk Pump Helm chart.

The Helm chart deployment steps will vary depending on your development environment and whether you are using Helm programmatically (through a script or a CI/CD pipeline) or manually running commands.

Here's a set of manual Helm commands you would typically run after your AKS cluster is up and running with kubectl already configured using the generated kubeConfig:

# Add the Tyk Helm repository
helm repo add tyk-helm https://helm.tyk.io/public/helm/charts/

# Update your Helm chart repository
helm repo update

# Install the Tyk Pump Helm chart
helm install tyk-pump tyk-helm/tyk-pump --version <chart-version>

Replace <chart-version> with the specific version of the Tyk Pump chart you wish to install. These commands will add the Tyk Helm chart repo, update it, and deploy the Tyk Pump to your AKS cluster.

Remember to check the Tyk Pump Helm chart documentation for any prerequisites, specific configurations, or parameters that may be required for the installation.
