Deploy the mev-boost helm chart on Oracle Kubernetes Engine (OKE)

Question

Pulumi · Accepted Answer

To deploy the mev-boost helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, you'll first need to create an OKE cluster or obtain credentials for an existing one. Once you have the cluster running and `kubeconfig` set up to interact with your cluster, you can use the Pulumi Kubernetes provider to deploy Helm charts.

Here's a step-by-step guide and a corresponding Pulumi TypeScript program to deploy the mev-boost helm chart on OKE:

### Prerequisites:

1. An Oracle Cloud Infrastructure account.
2. The `oci` CLI installed and configured on your local machine.
3. Pulumi CLI installed on your local machine.
4. Node.js installed to run the TypeScript Pulumi program.
5. Access to an existing OKE cluster or permissions to create one.

### Step 1: Configure Oracle Cloud Infrastructure (OCI) Credentials

Ensure you have the appropriate OCI credentials configured in your environment. This will include settings like user OCID, tenancy OCID, API key fingerprint, and region:

```bash
export OCI_USER_OCID="..."
export OCI_TENANCY_OCID="..."
export OCI_API_KEY_FINGERPRINT="..."
export OCI_PRIVATE_KEY_PATH="..."
export OCI_REGION="..."
```

### Step 2: Set up Oracle Kubernetes Engine (OKE)

If you don't have an existing OKE cluster, you'll need to create one either via the Oracle Cloud interface or using Pulumi.

### Step 3: Deploy the Helm Chart

The following Pulumi program will deploy the mev-boost helm chart to an Oracle Kubernetes Engine cluster. It uses the `kubernetes` package to interact with Kubernetes and assumes you have `kubeconfig` for your OKE cluster set up correctly.

In this program, we're using the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider to deploy the mev-boost Helm chart. If the Helm chart you require is hosted in a specific repository, you would also include the repository URL and potentially the chart version.

### TypeScript Program:

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

// Initialize a Kubernetes provider configured with the kubeconfig of your OKE cluster
const provider = new k8s.Provider('oke-provider', {
    kubeconfig: process.env.KUBECONFIG, // Ensure this environment variable is set with your OKE `kubeconfig`
});

// Deploy the mev-boost Helm chart into the cluster
const chart = new k8s.helm.v3.Chart('mev-boost', {
    chart: "mev-boost",
    // Uncomment the line below and replace `CHART_REPO_URL` if your chart is in a custom repository.
    // repo: "CHART_REPO_URL",
    // Optionally specify the Helm chart version
    // version: "CHART_VERSION",
    // Override default values from the chart by specifying custom values
    values: {
        // Replace with any custom values you need to provide to your mev-boost Helm chart
    },
}, { provider });

// Export the base URL for the mev-boost service
export const mevBoostUrl = chart.getResourceProperty('v1/Service', 'mev-boost-service', 'status').apply(status => status.loadBalancer.ingress[0].ip);

```

Make sure to replace any placeholder values in comments with actual values that are relevant to your environment and the Helm chart configuration you wish to use. For instance, `CHART_REPO_URL` would be the URL to the Helm chart's repository, and `CHART_VERSION` would be the specific chart version you want to install.

Ensure the `kubeconfig` file that allows Pulumi to communicate with your OKE cluster is available locally and set as an environment variable.

After the program is set up:

1. Run `pulumi up` to preview and deploy your stack.
2. Confirm the deployment to proceed with the real deployment to your OKE cluster.

The `export const mevBoostUrl` line makes sure to export the URL at which the mev-boost service can be accessed, assuming it is set to use a LoadBalancer service. If your configuration is different, you might need to tweak the export to suit your setup.

Remember to follow the documentation of the mev-boost Helm chart for specific configuration options that may be necessary for your particular deployment scenario.
