1. Deploy the aurora helm chart on Kubernetes


    Deploying the Aurora Helm chart on a Kubernetes cluster using Pulumi involves several steps. Firstly, ensure you have Helm and Pulumi installed and configured on your machine, and that you have a running Kubernetes cluster.

    Pulumi uses classes from various libraries to interact with cloud providers and provision infrastructure. To deploy a Helm chart, we typically use the Chart class from the @pulumi/kubernetes/helm module, which enables us to specify a Helm chart, its version, and any custom values we want to pass for deployment.

    The following program demonstrates how to deploy the Aurora Helm chart using Pulumi. This assumes that Aurora has a Helm chart available (please replace "aurora" with the correct chart name if it's different) and that you want to deploy it to the default namespace. If the chart is available in a Helm repository, you will need to set the repo property accordingly. You may also need to modify other properties such as values to match the configuration options required by the Aurora Helm chart.

    Here's how you can create a Pulumi program that deploys the Aurora Helm chart:

    import * as k8s from '@pulumi/kubernetes'; // Create a Kubernetes namespace (optional, you could deploy the chart in the default namespace). const namespace = new k8s.core.v1.Namespace("aurora-namespace", { metadata: { name: "aurora" } }); // Deploy the Aurora Helm chart in the newly created namespace. const auroraChart = new k8s.helm.v3.Chart("aurora", { chart: "aurora", // Replace with the actual chart name if different. version: "1.0.0", // Specify the chart version you want to deploy. namespace: namespace.metadata.name, // Referencing the namespace created above. // Specify custom values for the Helm chart (as an example). // Use the actual values that are appropriate for the Aurora Helm chart you are deploying. values: { // Example values; replace with those required by the Aurora chart replicaCount: 1, service: { type: "ClusterIP", port: 80, } }, // Add other properties such as `fetchOpts`, `transformations`, etc., if needed. }, { dependsOn: [namespace] }); // Export the base URL of the service once the chart is deployed export const auroraServiceUrl = auroraChart.getResourceProperty("v1/Service", "aurora", "status").apply(status => { const ingress = status.loadBalancer.ingress[0]; return ingress && ingress.hostname ? `http://${ingress.hostname}` : undefined; });

    In this Pulumi program, we first import the necessary Kubernetes module from Pulumi. We create a dedicated namespace called aurora-namespace for organizing our resources (this is optional and is used for illustrative purposes; you may choose to deploy in an existing namespace).

    Next, we declare a Chart resource specifying the Aurora Helm chart. We provide the name of the Helm chart ("aurora"), the desired chart version, and the target namespace to deploy the chart into.

    In the values property, we set the desired configuration for the Helm chart. This should be adjusted based on the specific configuration options required by the Aurora Helm chart. The dependsOn option is included to ensure that Helm deployment only takes place after the namespace has been created.

    Finally, we export the service URL to easily access the deployed chart. This example assumes that the service type of the Aurora deployment is LoadBalancer, which may provide an external endpoint. Adjust the code if the service type or access method is different.

    To run this Pulumi program:

    1. Save the code to a file named index.ts in your Pulumi project directory.
    2. Run pulumi up from the command line to preview and deploy the changes. Pulumi CLI will execute the code and provision the resources defined in it.
    3. Upon successful completion, Pulumi will output the exported values like auroraServiceUrl.
