Deploy the sumologic-fluentd helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the Sumo Logic Fluentd Helm chart on the DigitalOcean Kubernetes service using Pulumi, you'll need to perform a few steps:

1. Set up a DigitalOcean Kubernetes (DOKS) cluster
2. Install the Helm Chart for Sumo Logic Fluentd into the cluster

We'll use two Pulumi resources from the registry:

- [`digitalocean.KubernetesCluster`](https://www.pulumi.com/registry/packages/digitalocean/api-docs/kubernetescluster/): To create a managed Kubernetes cluster in DigitalOcean.
- [`kubernetes.helm.v3.Chart`](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/chart/): To deploy Helm charts to a Kubernetes cluster.

First, make sure you have Pulumi installed, and you have authenticated with DigitalOcean using a token and set up the necessary credentials for Pulumi to communicate with your DigitalOcean account.

Here's a Pulumi program written in TypeScript that demonstrates how to accomplish this task:

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

// Create a DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc3",
    version: "latest",
    nodePool: {
        name: "default-pool",
        size: "s-2vcpu-2gb",
        nodeCount: 1, // Adjust the number of nodes as needed
    },
});

// Once the cluster is created, we need to configure our Kubernetes provider to use the cluster's kubeconfig
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeConfigs[0].rawConfig,
});

// Deploy the Sumo Logic Fluentd Helm chart to the DigitalOcean Kubernetes cluster
const sumoLogicFluentdChart = new k8s.helm.v3.Chart("sumologic-fluentd", {
    chart: "fluentd",
    version: "0.0.0", // Replace with the appropriate chart version
    fetchOpts: {
        repo: "https://sumologic.github.io/sumologic-kubernetes-collection", // The Helm chart repository
    },
    values: {
        // Specify values for the Helm chart's configurable parameters
        // e.g., Sumo Logic endpoint, authentication credentials, etc.
    },
}, { provider: k8sProvider });

// Export the kubeconfig and the cluster's endpoint
export const kubeConfig = cluster.kubeConfigs[0].rawConfig;
export const clusterEndpoint = cluster.endpoint;
```

In this program:

1. We create a new DigitalOcean Kubernetes cluster with `digitalocean.KubernetesCluster`. We specify the region, version, and details for the node pool.
2. We create a Pulumi Kubernetes provider to interact with our new cluster using its `kubeconfig`.
3. We then deploy the Sumo Logic Fluentd Helm chart using `k8s.helm.v3.Chart`. We set the `chart` and `fetchOpts.repo` to the correct values for the Sumo Logic Fluentd Helm chart repository. You will need to replace the `version` with the specific chart version you wish to deploy, and the `values` field with any configuration settings relevant to your use case.
4. We also export the kubeconfig and the cluster's endpoint, so you can easily access your cluster outside of Pulumi.

Remember to replace placeholder values like `version: "0.0.0"` with the actual version you intend to use, which you can find from the Sumo Logic Helm chart documentation or chart repository.

To run this Pulumi program, you'll need to execute the following commands in your terminal:

```sh
pulumi up
```

This command creates the resources defined in the program and applies them to your cloud provider (DigitalOcean in this case). The `pulumi up` command automatically compiles the TypeScript code into JavaScript and then executes it to perform the deployment.
