Deploy the aurora helm chart on Rancher

Question

Pulumi · Accepted Answer

Deploying a Helm chart on Rancher using Pulumi involves several steps. Firstly, you need to set up the Pulumi environment for your target cloud provider (such as AWS, GCP, Azure) where your Rancher server is hosted. Secondly, you have to configure Pulumi to interact with the Rancher API.

Here's the general process of deploying the Aurora Helm chart on a Rancher Kubernetes cluster using Pulumi:

1. **Define your cloud provider resources**: Ensure that you have a Kubernetes cluster managed by Rancher. In this case, since we're deploying Amazon Aurora, your cluster is likely running on AWS. You don't have to define any AWS resources in your Pulumi program if the cluster is pre-existing and managed outside of Pulumi.

2. **Configure the Rancher2 provider**: You need to set up the Rancher2 provider so that Pulumi can communicate with your Rancher instance to manage the Helm chart.

3. **Deploy the Helm chart**: Once the provider is configured, you can use Pulumi to deploy the Aurora Helm chart to the desired namespace in your Rancher-managed cluster.

Below is a Pulumi program written in TypeScript that demonstrates these steps. It assumes you already have a Kubernetes cluster managed by Rancher, and you have administrative access and configuration details such as the cluster ID and access credentials.

```typescript
import * as pulumi from '@pulumi/pulumi';
import * as rancher2 from '@pulumi/rancher2';
import * as k8s from '@pulumi/kubernetes';

// Create a new Rancher2 provider instance.
// Replace `rancherApiUrl`, `rancherAccessKey`, and `rancherSecretKey` with your Rancher API endpoint and credentials.
const rancherProvider = new rancher2.Provider('my-rancher-provider', {
    apiUrl: 'rancherApiUrl',
    accessKey: 'rancherAccessKey',
    secretKey: 'rancherSecretKey',
});

// The Rancher cluster where you want to deploy the Aurora Helm chart.
// Replace `rancherClusterId` with the cluster ID obtained from your Rancher UI or API.
const cluster = new rancher2.Cluster('my-rancher-cluster', {
    clusterId: 'rancherClusterId',
}, { provider: rancherProvider });

// Deploying the Aurora Helm chart on the cluster.
// Helm chart details, such as the repository and chart name, may vary,
// replace `repoUrl` with the actual Helm repository URL, `chartVersion` with the chart version you wish to use,
// and `values` with the appropriate chart values.
const auroraHelmChart = new k8s.helm.v3.Chart('aurora', {
    chart: 'aurora',
    version: 'chartVersion',
    fetchOpts: {
        repo: 'repoUrl',
    },
    values: {
        // Provide the necessary values for the Aurora Helm chart
    },
}, { provider: new k8s.Provider('k8s', { kubeconfig: cluster.kubeConfigRaw }) });

// Export the Kubernetes config to be able to connect to the cluster using kubectl.
// The `kubeConfigRaw` can be used to access your Rancher Kubernetes cluster externally.
export const kubeConfig = cluster.kubeConfigRaw;
```

In the code above `rancherApiUrl`, `rancherAccessKey`, `rancherSecretKey`, and `rancherClusterId` are placeholders for your actual Rancher API URL, access key, secret key, and the specific cluster ID respectively. Also, `repoUrl` and `chartVersion` are placeholders for the Helm chart repository URL and the version of the Aurora chart you want to deploy.

Once the program is executed, the Aurora Helm chart will be deployed onto your Rancher Kubernetes cluster. Keep in mind that this is a basic representation and actual values will vary based on your configuration and the specifics of the Aurora Helm chart you wish to deploy. Make sure you have the necessary permissions and the correct configuration information before running this code.
