1. Deploy the grafana-dashboards-rancher helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the grafana-dashboards-rancher Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, we'll first need to set up a few things:

    1. A Kubernetes cluster running in OKE (Assuming you already have this).
    2. A Pulumi program to deploy your Helm chart.

    The following Pulumi TypeScript program will assume you have an existing OKE cluster. If you don't already have a cluster, you'll need to set that up first. Pulumi has resources available for creating a new OKE cluster, but that is out of scope for this response.

    We'll use the kubernetes package to interact with Kubernetes from Pulumi; specifically, we will utilize the helm.sh/v3.Chart class, which represents a Helm chart in a Pulumi program. For deploying Helm charts, Pulumi interacts with the Kubernetes API server's Helm support, so you will need to have kubectl configured to talk to your OKE cluster.

    Here's the full program to deploy the grafana-dashboards-rancher Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // Create an instance of the kubernetes provider connected to the existing cluster. const provider = new k8s.Provider("oke", { kubeconfig: "<Your OKE cluster kubeconfig>", }); // Deploy the grafana-dashboards-rancher helm chart. const grafanaDashboardsChart = new k8s.helm.v3.Chart("grafana-dashboards-chart", { chart: "grafana-dashboards-rancher", version: "<Chart version>", // Specify the version of the chart you want to deploy fetchOpts:{ repo: "https://grafana.github.io/helm-charts", // This should be the repository where your desired chart is located }, }, { provider }); // Export the public IP to access the Grafana Dashboard export const grafanaServiceIp = grafanaDashboardsChart.getResourceProperty('v1/Service', 'grafana-dashboards-rancher', 'status').apply(status => status.loadBalancer.ingress[0].ip);

    In the above program:

    • We import the @pulumi/kubernetes package, which contains the necessary helpers to interact with Kubernetes.
    • We instantiate a Provider which encapsulates the connection to your Kubernetes cluster. You would replace <Your OKE cluster kubeconfig> with your cluster's kubeconfig.
    • We instantiate a Chart resource, which represents the Helm chart we want to deploy. You should specify the exact version of the Helm chart you want to install.
    • We're defining the fetchOpts.repo which is the URL of the Helm repository that contains the chart we want. This should point to the repository where the grafana-dashboards-rancher chart is located.

    Remember that for Helm charts that require values, you can specify them in the values argument to the Chart constructor. For example:

    values: { persistence: { enabled: true, size: "10Gi" }, service: { type: "LoadBalancer" } },

    Finally, we export an IP address that can be used to access the Grafana dashboard; this assumes the service type of LoadBalancer, which may vary based on your Helm chart configuration.

    Make sure to replace placeholder tokens with actual values appropriate for your setup. Once you apply this Pulumi program with pulumi up, it will deploy the specified Helm chart onto your OKE cluster.
