1. Deploy the snappass helm chart on Kubernetes

    TypeScript

    To deploy the snappass Helm chart on a Kubernetes cluster using Pulumi, you need to have a Kubernetes cluster already running and have kubectl configured to communicate with the cluster. Pulumi will use the same configuration context that kubectl uses.

    In the following Pulumi program, we will be using the @pulumi/kubernetes package to interact with the Kubernetes cluster and deploy a Helm chart. The kubernetes.helm.v3.Chart class is used for deploying the Helm chart to your cluster. You need to specify the chart name and other optional parameters such as values to customize the deployment.

    Here's a TypeScript program that demonstrates how to deploy the snappass Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // Create a Helm Chart resource. This chart will be fetched from the default Helm repo. const snappassChart = new k8s.helm.v3.Chart("snappass", { repo: "stable", // Replace with the repo where snappass chart is located, if necessary. chart: "snappass", values: { // Custom values for `snappass` chart can be provided here. // For example, you can change service type to LoadBalancer to expose `snappass` publicly: // service: { // type: "LoadBalancer", // } // Make sure to refer to the `snappass` Helm chart documentation for all available options. }, }); // Export the public IP address of the `snappass` service (if LoadBalancer is enabled). export const snappassServiceIp = snappassChart.getResourceProperty( "v1/Service", "snappass", "status" ).apply(status => status.loadBalancer?.ingress[0]?.ip || "Not assigned");

    In this program:

    • We import the @pulumi/kubernetes package which contains the necessary utilities to interact with Kubernetes.
    • We create a new Helm chart instance named snappassChart with the kubernetes.helm.v3.Chart class.
    • The repo argument should be set to the name of the Helm repository containing the snappass chart. If the Helm chart is in the stable repository, then you can specify stable. Otherwise, you will need to specify the correct repository or even omit the repo property if it's in your local Helm repo.
    • The chart argument is the name of the chart to deploy, in this case, snappass.
    • The values object is a place where you can specify any configuration settings that the snappass Helm chart allows. This will often include things like replica counts, image versions, or service types. These values need to be structured according to the specific Helm chart's expected format.
    • We export the snappassServiceIp using getResourceProperty to potentially fetch the public IP address assigned by the LoadBalancer service. It's important to note that we only get an IP if a service of type LoadBalancer is used and the cloud provider supports dynamic IP assignment.

    Before running this code, make sure you have Pulumi installed and configured to use your Kubernetes cluster. If needed, install the Pulumi CLI from Pulumi Installation and log in using pulumi login.

    To apply the Pulumi program, you would typically navigate to the directory containing this code and then run:

    pulumi up

    This will start the Pulumi program, which in turn will deploy the snappass Helm chart in your Kubernetes cluster. If you haven't set up a Pulumi project and stack yet, you'll need to do that before running pulumi up. You can find more about creating a new Pulumi project on the Pulumi Project page.

    After deploying, pulumi up will output the public IP address of the snappass service if it was made publicly accessible via a service of type LoadBalancer and if your cloud provider's Kubernetes service supports it. If not, it will output "Not assigned".

    Please note that depending on where your Kubernetes cluster is hosted and the specifics of the snappass Helm chart, you may need to adjust the values to fit your environment and the Helm chart's requirements. Always refer to the Helm chart's documentation for detailed configuration options.
