1. Deploy the jh-gitlab helm chart on Kubernetes


    To deploy the jh-gitlab Helm chart on Kubernetes using Pulumi, we'll utilize the kubernetes package which allows us to interact with Kubernetes resources directly. Specifically, we'll use the Chart class from the kubernetes.helm.v3 module to deploy the Helm chart.

    The Chart resource lets you apply a Helm chart from a repository to your Kubernetes cluster. You need to provide the chart name, the repository URL where the chart can be found (if it's not a local chart), and optionally, any values you want to override in the chart's default values.yaml file.

    Below is a Pulumi program written in TypeScript that performs the deployment. First, set up your Kubernetes cluster configuration in Pulumi (assuming you have already configured kubectl to point to your cluster), and then apply the Helm chart.

    Before you run the code, make sure you have Pulumi installed and configured for TypeScript. You also need access to a Kubernetes cluster and kubectl configured to communicate with it.

    Here is a Pulumi program in TypeScript that deploys the jh-gitlab Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // Define the settings for the Helm chart. const chartName = "gitlab"; const chartVersion = "X.Y.Z"; // Replace with the actual chart version you want to deploy const releaseName = "jh-gitlab-release"; const namespace = "default"; // The namespace where you want the chart to be deployed // Create a Helm Chart resource using the Pulumi Kubernetes provider. const gitlabChart = new k8s.helm.v3.Chart(releaseName, { chart: chartName, version: chartVersion, namespace: namespace, fetchOpts: { repo: "https://charts.gitlab.io", // The Helm chart repository URL }, // If you need to provide custom values to the Helm chart, specify them here. // For example, to set the `serviceType` for GitLab to `LoadBalancer`, you can uncomment the following line: // values: { // gitlab: { // serviceType: "LoadBalancer", // }, // }, }); // Export the IP address of the GitLab service, assuming it is of type LoadBalancer. // You need to adjust this if you set a different service type. export const gitlabIP = gitlabChart.getResourceProperty( "v1/Service", `${releaseName}-gitlab`, "status", "loadBalancer", "ingress", 0, "ip" );
    1. Modify the chartVersion variable to match the version of the jh-gitlab Helm chart you want to use.
    2. The releaseName is the name you want to give to your Helm release. This name must be unique within the Kubernetes namespace.
    3. The Helm chart is deployed in a Kubernetes namespace, specified by the namespace variable. In this example, we used the default namespace.
    4. fetchOpts contains an object with the repository URL (in repo) where Pulumi can find the Helm chart.
    5. The values dictionary can be used to override the default values found in the chart's values.yaml. In the commented-out example, we're setting the serviceType for GitLab to LoadBalancer. You would uncomment and adjust this part to match your configuration needs.
    6. Finally, we export the GitLab IP address. This assumes that the GitLab service is configured with a LoadBalancer. If using a different service type, such as ClusterIP or NodePort, adjust this accordingly.

    Before applying this Pulumi code, make sure to replace "X.Y.Z" with the exact version of the jh-gitlab chart you want to deploy.

    To apply this Pulumi program:

    1. Save the code to a file with a .ts suffix—for example, deployGitlab.ts.
    2. Run pulumi up from the same directory as your file.
    3. Pulumi will show you a preview of the resources that will be created. If everything looks correct, confirm the deployment by selecting yes.

    Once the deployment is successful, you should see output variables displayed in your terminal, including the external IP address for the GitLab service, which you can use to access your GitLab instance if you have set the serviceType to LoadBalancer.
