1. Deploy the gantt helm chart on Digital Ocean Kubernetes Service


    To deploy the Gantt Helm chart on the DigitalOcean Kubernetes Service (DOKS), you would typically go through the following steps:

    1. Set up your DigitalOcean Kubernetes Cluster:

      • Create a Kubernetes cluster on DigitalOcean through the DigitalOcean console or CLI.
      • Ensure you have the necessary credentials and kubeconfig file to interact with your cluster.
    2. Prepare the Helm chart:

      • Locate or create the Helm chart that you want to deploy, which, in this case, is the "Gantt" chart. Helm charts define the structure and installation instructions for Kubernetes applications.
    3. Deploy the Helm chart:

      • Use Pulumi to write infrastructure as code that defines the desired state of your Kubernetes resources, including your Helm chart deployment.

    Below is a Pulumi program written in TypeScript that illustrates how you can use Pulumi to deploy a Helm chart to a DigitalOcean Kubernetes cluster. This example assumes that you have already created a DOKS cluster and have obtained the kubeconfig for access.

    Pulumi Program Explanation

    1. DigitalOcean Provider: We start by importing the DigitalOcean provider to interact with the DigitalOcean APIs.
    2. Kubernetes Provider: Next, we import the Kubernetes provider, which allows Pulumi to interact with the Kubernetes cluster.
    3. Kubernetes Cluster: We retrieve the existing DigitalOcean Kubernetes cluster information.
    4. Helm Chart: Finally, we define a Helm chart resource using the Gantt chart details such as name, version, and any specific configurations required.

    Let's see how this would look in code:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Replace the following variables with the appropriate values for your setup. const doKubeconfig = "<YOUR_DIGITALOCEAN_KUBECONFIG>"; const ganttChartVersion = "<DESIRED_CHART_VERSION>"; // Specify the chart version you want to deploy const ganttChartName = "gantt"; // The name of the chart you want to deploy (might need to change this based on the actual chart name) // Create a provider instance with the DigitalOcean Kubernetes cluster kubeconfig. const k8sProvider = new kubernetes.Provider("do-k8s-provider", { kubeconfig: doKubeconfig, }); // Fetch the DigitalOcean Kubernetes cluster that you have already created, // this assumes you have set up your DigitalOcean Kubernetes cluster. // Replace `my-cluster-name` with the name of your DigitalOcean Kubernetes cluster. const cluster = digitalocean.KubernetesCluster.get("my-cluster", "<DIGITALOCEAN_CLUSTER_ID>"); // Deploy the Gantt Helm chart to the DigitalOcean Kubernetes Service (DOKS) cluster. const ganttHelmChart = new kubernetes.helm.v3.Chart("gantt-chart", { chart: ganttChartName, version: ganttChartVersion, // Add other Helm chart values here }, { provider: k8sProvider }); // Export the Kubernetes cluster's name and the Helm chart deployment status. export const clusterName = cluster.name; export const helmDeploymentStatus = ganttHelmChart.status;

    Next Steps

    • Replace the placeholders in doKubeconfig, ganttChartVersion, and DIGITALOCEAN_CLUSTER_ID with your actual kubeconfig content, chart version, and cluster ID.
    • If there are any specific values or configurations that the Gantt chart requires, include them in the Helm chart definition.
    • Run the Pulumi program with the Pulumi CLI to deploy the Helm chart.

    This program uses Pulumi's Kubernetes provider to deploy a Helm chart into an existing DOKS cluster. The kubeconfig is needed to authenticate against your Kubernetes cluster, and it should be set to the configuration file content you get after creating a DigitalOcean Kubernetes cluster.

    To apply this Pulumi program:

    1. Save the code to a file named index.ts.
    2. Run pulumi up in the directory containing the index.ts file. This command will start the deployment process.

    Please make sure you have Pulumi installed and configured with the necessary cloud provider credentials before running the program.
