1. Deploy the desktop-vnc helm chart on Kubernetes


    To deploy the desktop-vnc Helm chart on Kubernetes using Pulumi, you would write a TypeScript program that uses Pulumi's Kubernetes provider. This program will create a Helm chart resource pointing at the desktop-vnc chart.

    Below, you'll find a Pulumi program written in TypeScript that demonstrates how to do this. Make sure you have Pulumi installed and configured to use your Kubernetes cluster context before you run this program.

    Here are the steps that the program performs:

    1. Import necessary packages.
    2. Create an instance of the Chart class from the Pulumi Kubernetes provider, which represents a Helm chart.
    3. Configure the chart with the necessary arguments such as the chart name and version (optional).

    Make sure you have desktop-vnc available in your Helm repository, or specify the repository URL if it's located in a custom Helm repository.

    Here is the program to deploy the desktop-vnc Helm chart on Kubernetes:

    import * as k8s from '@pulumi/kubernetes'; // Create a Helm Chart resource that deploys the desktop-vnc chart. // You need to specify the repository where the chart can be found if it's not // in the local helm repo or in stable/nublify repo. const desktopVncChart = new k8s.helm.v3.Chart('desktop-vnc', { chart: 'desktop-vnc', // Uncomment and set the repo if the chart is in a custom helm repository. // repo: 'http://example.com/helm-charts', // Optionally, you can specify the version of the chart. // version: '1.2.3', // values can be used to provide configuration details for the chart. values: { /* Replace with Chart values, for example: service: { type: 'NodePort', }, */ }, // Specify the namespace where the chart should be deployed, if not default. // namespace: 'my-namespace', }, { // Enable the skipAwait option if you want Pulumi to not wait for all resources to be available before moving on. // skipAwait: true, }); // Optionally, export any of the values you might need to access once the Helm chart is deployed. // For example, if the chart creates a LoadBalancer service, you might want to export the endpoint: // export const endpoint = desktopVncChart.getResourceProperty('v1/Service', 'desktop-vnc-service', 'status').apply(status => status.loadBalancer.ingress[0].ip);

    Understanding the Code:

    • @pulumi/kubernetes: This package provides the interfaces to interact with Kubernetes. It supports resources such as Pods, Deployments, Services, and higher-level components like Helm charts.

    • k8s.helm.v3.Chart: This is a resource class provided by Pulumi to deploy Helm charts. When this resource is instantiated, Pulumi will deploy the specified Helm chart to the connected Kubernetes cluster.

    • values: Here you would input the custom values you need to configure the Helm chart. These are equivalent to the values you would set in a values.yaml file or pass to helm install via --set or --values. These settings should be configured according to the specific chart's documentation and your requirements.

    • namespace: If you want to deploy your Helm chart in a specific Kubernetes namespace, you would set it here.

    • skipAwait: By default, Pulumi waits for all resources to be fully ready before considering the deployment a success. If you're deploying a workload that doesn't report full readiness to Kubernetes but is nonetheless considered ready by your criteria, you can set skipAwait to true.

    After you run this Pulumi program, it will use your current Kubernetes configuration context to deploy the desktop-vnc Helm chart to your cluster. If you have not already configured your Pulumi credentials to work with your Kubernetes cluster, you will need to do so before running this program.
