Deploy the jaeger-cert-manager helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy the `jaeger-cert-manager` Helm chart on Linode Kubernetes Engine using Pulumi, you will need to use the Pulumi Kubernetes provider. The key resource for deploying Helm charts is the `Chart` resource, which installs a set of Kubernetes resources into a cluster from a Helm chart.

Below is a step-by-step program written in TypeScript that demonstrates how to accomplish this using Pulumi.

1. **Set up a new Pulumi project**: If you have not done so, create a new directory for your Pulumi project, run `pulumi new` to create a new Pulumi project, and choose the Kubernetes TypeScript template.

2. **Configure Kubernetes provider**: Before running the Pulumi program, ensure you have configured access to your Linode Kubernetes cluster by setting up the `kubeconfig` file. Pulumi uses the `kubeconfig` file to interact with your Kubernetes cluster.

3. **Install the required Pulumi packages**: You will need the `@pulumi/kubernetes` package for this program.

You can install it using npm:
   ```sh
   npm install @pulumi/kubernetes
   ```

4. **Write the Pulumi program**: Use the `Chart` resource from the `@pulumi/kubernetes` package to deploy `jaeger-cert-manager` using its Helm chart.

Below is the detailed Pulumi program that deploys the `jaeger-cert-manager` Helm chart.

```typescript
import * as k8s from "@pulumi/kubernetes";

// Name your chart, providing the name of the Helm chart you want to deploy. Ensure the chart version and name are accurate.
const jaegerCertManagerChart = new k8s.helm.v3.Chart("jaeger-cert-manager", {
    // Provide the repository and the chart details where `jaeger-cert-manager` is located.
    // If the chart is in the official Helm repository, you would not need the 'repo' attribute.
    chart: "jaeger-cert-manager",
    version: "1.0.0", // replace with the correct chart version
    fetchOpts: {
        // In this example, assuming jaeger-cert-manager chart is publicly available if not, provide the repo URL.
        repo: "https://jaeger-helm-charts.storage.googleapis.com/",
    },
    // Define values from the values.yaml or to override default values.
    // This is similar to the `--set` flag when using the `helm` CLI.
    values: {
        // Custom values go here for your Helm chart, as an example:
        storage: {
            type: "LinodeBlockStorage",
        },
        // add any other necessary values that you need to configure `jaeger-cert-manager`
    },
}, { provider: linodeK8sProvider }); // If you have a specific Linode provider instance, supply it here

// Export the resources created by the chart for easy access to their info
export const chartResources = jaegerCertManagerChart.resources;
```

In this program, replace `1.0.0` with the actual version of the Helm chart you want to deploy.

Remember to correctly set up the Pulumi Kubernetes provider with the required configuration to connect to your Linode Kubernetes cluster.

After writing this program to a file in your Pulumi project, you can deploy the chart to your Linode Kubernetes cluster using the Pulumi CLI commands:

```sh
pulumi up
```

The command will display a preview of the resources to be deployed and, upon confirmation, will proceed to deploy the Helm chart to the Linode Kubernetes cluster.

Please ensure that you have the necessary permissions to deploy the Helm chart and create associated Kubernetes resources in your cluster.
