1. Deploy the teleport-plugin-mattermost helm chart on Opensshift


    To deploy the teleport-plugin-mattermost Helm chart on OpenShift using Pulumi, we will use the kubernetes package. This package provides the necessary resources to deploy applications using Helm charts on a Kubernetes cluster, including OpenShift. We'll specifically use the Chart resource to manage the Helm chart installation.

    OpenShift is a Kubernetes distribution from Red Hat, so you can generally treat it like a Kubernetes cluster with a few additional security and user management features. Before deploying a Helm chart to OpenShift, you need to have access to an OpenShift cluster and the oc command-line tool configured with the credentials for your OpenShift cluster.

    The Chart resource from the kubernetes package is used because it can handle the deployment of Helm charts in a Kubernetes cluster, and OpenShift is fully compatible with Kubernetes Helm charts.

    Below is a Pulumi program written in TypeScript that you can use to deploy the teleport-plugin-mattermost Helm chart to an OpenShift cluster. The program assumes that you have set up your Pulumi environment and OpenShift credentials. It also assumes that the Helm chart named teleport-plugin-mattermost is available in a reachable Helm repository.

    import * as k8s from "@pulumi/kubernetes"; // Define the settings for the Helm chart. // Adjust the `chart`, `repo`, `values`, or other parameters as needed. const mattermostChart = new k8s.helm.v3.Chart("teleport-plugin-mattermost", { // Assuming "mattermost" is the name of the chart in the repository chart: "mattermost", // Specify your Helm repository name here repo: "your-helm-repo", // You can specify the Helm chart version you wish to deploy version: "x.y.z", // Specify the namespace where the chart will be installed namespace: "default", // If needed, provide chart values here values: {}, // The Helm fetch options can be set here if necessary fetchOpts: { // For example, if the repository requires a username and password username: "repo-username", password: "repo-password", }, }); // Export the base URL of the Mattermost instance if it is exposed via an Ingress or LoadBalancer export const mattermostUrl = mattermostChart.getResourceProperty("v1/Service", "teleport-plugin-mattermost", "status") .apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip);

    This program will deploy the teleport-plugin-mattermost Helm chart using the chart and repository information provided. The values object is where you can define any overrides for the default settings that the Helm chart provides. You might not need fetchOpts if your Helm repository doesn't require authentication, so you can omit those options if they're not necessary.

    The mattermostUrl export is designed to provide the URL to access your Mattermost instance. If your chart exposes the Mattermost service via an Ingress or a LoadBalancer, you will be able to get the URL from this export. If your service is exposed differently (for example, via Route on OpenShift), you'll need to adjust the retrieval of the mattermostUrl accordingly.

    Before running the Pulumi program, make sure to install the Pulumi CLI, set up your Pulumi project, and have the Pulumi Kuberentes provider configured to connect to your OpenShift cluster.

    When you run this Pulumi program using pulumi up, it will interact with the OpenShift API to deploy the Helm chart you've specified according to the provided configuration settings.
