1. Deploy the prometheus-operator-mixin helm chart on Oracle Kubernetes Engine (OKE)


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

    1. Set up Oracle Kubernetes Engine (OKE): We will need to have an OKE cluster up and running to deploy the Helm chart. For the purposes of this example, we'll assume you already have a cluster provisioned.

    2. Install the Pulumi CLI and set up the Pulumi project: Ensure you have the Pulumi CLI installed on your system and authenticate with Oracle Cloud Infrastructure to manage resources.

    3. Write the Pulumi TypeScript program: In this program, we will add the necessary Pulumi package dependencies which include @pulumi/kubernetes for interacting with Kubernetes resources and deploying Helm charts.

    4. Deploy the prometheus-operator-mixin Helm Chart: We will use the Chart resource from the Pulumi Kubernetes provider to deploy the prometheus-operator-mixin helm chart to the OKE cluster.

    Here is the detailed Pulumi TypeScript program:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create a provider for the existing Oracle Kubernetes Engine cluster. // We're assuming you have a kubeconfig file that provides access to your OKE cluster. // The kubeconfig can be sourced from an environment variable or a file on disk. const provider = new k8s.Provider("oke-k8s", { kubeconfig: process.env.KUBECONFIG, // If your kubeconfig is in a file, use the following line instead: // kubeconfig: pulumi.output(pulumi.fs.readFile("path-to-your-kubeconfig.yaml")).apply(contents => contents), }); // Reference to your cluster's namespace where you want to deploy the Helm chart. // If this namespace does not exist, you should create it using `kubectl` or a Pulumi Kubernetes resource. const namespace = "default"; // Deploy the prometheus-operator-mixin helm chart. const prometheusOperatorMixinChart = new k8s.helm.v3.Chart("prometheus-operator-mixin", { chart: "kube-prometheus-stack", // Generally, the prometheus-operator-mixin is part of the kube-prometheus-stack. version: "<specific chart version>", // Replace with the desired chart version. namespace: namespace, fetchOpts: { repo: "https://prometheus-community.github.io/helm-charts", // The Helm repository where the chart is stored. }, values: { // Provide any custom values required for your prometheus-operator-mixin installation. // Refer to the chart's values.yaml or official documentation for available options. }, }, { provider }); // Export the Helm release's status as an output. export const prometheusOperatorMixinStatus = prometheusOperatorMixinChart.status;

    This program will set up Pulumi to use your existing Oracle Kubernetes Engine cluster and deploy the prometheus-operator-mixin included in the kube-prometheus-stack Helm chart from the Prometheus Community Helm charts repository.

    Please replace <specific chart version> with the version number of the chart you wish to deploy. You can find available versions in the chart repository or by running helm search repo prometheus-community/kube-prometheus-stack.

    Note that we have not included any authentication setup for Oracle Cloud Infrastructure or Kubernetes; this is something you'll need to have in place before running the Pulumi program. Ensure that you have set up your environment variables or configuration files that provide the necessary credentials.

    To execute this program:

    1. Save the code to a file with a .ts extension, for example: deploy-prometheus-oke.ts.
    2. Run pulumi up from the command line within the same directory to create the resources as specified.

    Ensure you review the plan provided by Pulumi before confirming the deployment to avoid any unintended changes to your infrastructure.
