1. Deploy the gitea-instance helm chart on Opensshift


    To deploy the Gitea instance Helm chart on an OpenShift cluster using Pulumi, you will need to use resources from the Pulumi Kubernetes provider. The main resource you'll interact with is kubernetes.helm.v3.Chart, which represents a Helm chart resource in a Kubernetes cluster.

    Here's how you can proceed to deploy a Gitea instance using Helm on OpenShift:

    1. Prerequisites: Ensure you have Pulumi installed, access to an OpenShift cluster, and that you have Helm and kubectl configured to work with your cluster.

    2. Setup the Pulumi Project: A Pulumi project needs to be set up. Normally, this step involves running pulumi new and selecting an appropriate template. For TypeScript, you would select the Kubernetes TypeScript template.

    3. Define the Helm Chart Resource: Use the Chart resource within the project to define the Gitea Helm chart. You must specify the chart name, version (if needed), and any custom values you want to apply. You can also specify the repository from where to fetch the chart if it's not a part of the default Helm repositories.

    4. Deploy to OpenShift: Once the Chart resource is set up in your Pulumi program, pulumi up will deploy the chart to your OpenShift cluster.

    Below is a TypeScript program that includes these steps. You will need to replace your OpenShift cluster details where appropriate.

    import * as kubernetes from '@pulumi/kubernetes'; // Step 1: Prepare access to your OpenShift cluster. // Pulumi uses your existing Kubeconfig file by default, make sure it's configured for OpenShift. // Step 2: Define the Gitea Helm chart resource. const giteaChart = new kubernetes.helm.v3.Chart('gitea-instance', { // If the Gitea chart is in a custom Helm repo, use the `repo` property to specify it // For example: repo: 'https://helm.gitea.io', chart: 'gitea', // You can also specify the chart version you wish to install version: '2.1.2', // replace with the desired version // If you have specific configurations you want to override, provide them here. values: { // Example of setting service type to NodePort, specify your own values as needed service: { type: 'NodePort', }, // ...other custom values }, // Namespace in which to deploy the chart, if not specified, it defaults to 'default' namespace: 'gitea-namespace', }); // Step 3: Deploy the chart using Pulumi. // Run `pulumi up` to execute the deployment. // Step 4 (Optional): Export the endpoint to access Gitea after deployment. export const giteaEndpoint = giteaChart.getResource('v1/Service', 'gitea-instance-gitea').status.apply(s => { if (s.loadBalancer.ingress && s.loadBalancer.ingress.length > 0) { // If using LoadBalancer service type return s.loadBalancer.ingress[0].ip || s.loadBalancer.ingress[0].hostname; } else { return 'Please check your service type and configuration to get the external IP or hostname'; } });

    In this program, we:

    • Import the Pulumi Kubernetes package.
    • Assume that you've already configured access to your OpenShift cluster through your Kubeconfig.
    • Create a new Helm chart resource for Gitea, specifying the chart name and optional version, as well as any configuration overrides you wish to apply in the values block.
    • Optionally export the service endpoint if you're using a LoadBalancer service type that provides an external endpoint. This will help you access your Gitea instance from outside the cluster.

    To apply this Pulumi program, navigate to the directory containing this file and run pulumi up. After confirmation, Pulumi will deploy the Gitea Helm chart to your OpenShift cluster. If you haven’t installed the Pulumi CLI yet, please visit Install Pulumi for instructions on installing the CLI and setting up your Pulumi project.

    Keep in mind, since Helm charts can have many configuration options, you might need to refer to the Gitea Helm chart documentation for all available configuration parameters. Adjust the values block in the program above to suit your actual requirements.
