1. Deploy the prom2teams helm chart on Oracle Kubernetes Engine (OKE)


    To deploy the prom2teams Helm chart on Oracle Kubernetes Engine (OKE), we will follow these steps using Pulumi:

    1. Set up an OKE cluster. To keep it simple, we assume that an OKE cluster is already available and correctly configured with kubectl. If you need to create a cluster, you can use the oci.ContainerEngine.Cluster and oci.ContainerEngine.NodePool resources.

    2. Use the Helm Chart resource from Pulumi's Kubernetes provider to deploy prom2teams.

    3. Ensure you have the necessary configuration in place, such as the Oracle Cloud Infrastructure (OCI) credentials, context for kubectl, and Helm repository added where the prom2teams chart is located.

    For the purpose of this guide, we'll focus on the deployment step assuming that you have a running OKE cluster, and the OCI CLI is already configured to communicate with your Oracle Cloud account.

    We'll use the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes package to deploy the prom2teams chart. This resource lets us specify Helm chart's details and configurations through Pulumi, similar to how you'd specify them using Helm directly. We'll consider prom2teams to be available from a public Helm repository; if it's not, you'd need to add a repository with helm repo add.

    Here is the TypeScript program to deploy the prom2teams Helm chart on OKE:

    import * as k8s from '@pulumi/kubernetes'; // Assuming you have the Helm repository added where the `prom2teams` chart is located: // `helm repo add prom2teams https://prom2teams.github.io/` // Deploy prom2teams using a Helm Chart. // We will use release name "prom2teams-release" and install it in the default namespace. const prom2teamsChart = new k8s.helm.v3.Chart("prom2teams-release", { chart: "prom2teams", version: "3.2.1", // Specify the version of the chart you wish to deploy fetchOpts: { repo: "https://prom2teams.github.io/" }, // Add custom values here values: { // Provide any specific configurations you want to apply to prom2teams // For example, configMap with connector configuration if required by prom2teams configMap: { connectors: "http://prom2teams-connector:8089", // Replace with your connector URL if necessary }, }, }); // Export the URL to the prom2teams service // Depending on how the prom2teams chart exposes its service, you may need to get the appropriate service resource. // Here we assume a service named `prom2teams-release-prom2teams` is created by the chart and it's of type LoadBalancer. export const prom2teamsServiceUrl = prom2teamsChart.getResourceProperty("v1/Service", "prom2teams-release-prom2teams", "status") .apply(status => `http://${status.loadBalancer.ingress[0].ip}`);

    This program defines a Helm chart resource named prom2teams-release for the prom2teams chart. We specify the version of the chart and a repository where the chart can be fetched. The values object allows us to customize the deployment settings that would normally be provided in a values.yaml file or via --set command-line arguments to Helm.

    This Helm chart resource will instruct Pulumi to use the Kubernetes API to install or update the chart in your OKE cluster. Finally, we export the LoadBalancer IP for the deployed prom2teams service so you can access it outside the cluster.

    Before running this Pulumi program, ensure you've selected the correct stack matching your OKE cluster's configuration, and that your Pulumi CLI is authenticated to the Oracle Cloud through the OCI CLI.

    Replace version and values as needed to match with the exact configuration you desire. Ensure to check prom2teams documentation for all available options.

    To run this program, save it to a file, install the necessary dependencies with npm install @pulumi/kubernetes, and then execute pulumi up.

    Please replace the placeholder data such as version, chart, and values according to the specific prom2teams chart version and configurations you need. If you need to add custom logic for fetching the service details, modify the prom2teamsServiceUrl accordingly.
