Deploy the bitwarden-rs helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

In order to deploy the `bitwarden-rs` Helm chart on Azure Kubernetes Service (AKS), we will perform several steps using Pulumi:

1. **Create an AKS cluster**: We will define an AKS cluster where our application will be deployed.
2. **Install the Helm chart**: Once the cluster is set up, we will install the `bitwarden-rs` Helm chart on the AKS cluster using Pulumi's Helm support.

To get started, you'll need to have the Pulumi CLI installed and have an Azure account configured with the necessary permissions.

Here is a Pulumi program that demonstrates how to complete these steps:

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

// Step 1: Set up the AKS Cluster
const resourceGroup = new azure.core.ResourceGroup('myResourceGroup', {
    location: "East US", // You can choose the location that is best for you
});

const aksCluster = new azure.containerservice.KubernetesCluster('myAksCluster', {
    // Define the properties of the AKS cluster here
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    defaultNodePool: {
        name: "aksagentpool",
        nodeCount: 2,
        vmSize: "Standard_DS2_v2",
    },
    dnsPrefix: `${pulumi.getStack()}-kube`,
    linuxProfile: {
        adminUsername: "aksuser",
        sshKey: {
            keyData: "ssh-rsa YOUR_SSH_PUBLIC_KEY_HERE", // replace with your SSH public key
        },
    },
    servicePrincipal: {
        clientId: "YOUR_SERVICE_PRINCIPAL_CLIENT_ID", // replace with your Service Principal Client ID
        clientSecret: "YOUR_SERVICE_PRINCIPAL_CLIENT_SECRET", // replace with your Service Principal Client Secret
    },
});

// Output the kubeconfig to be used by Pulumi to deploy the Helm chart
const kubeconfig = aksCluster.kubeConfigRaw;

// Step 2: Deploy the Bitwarden-rs Helm chart to the AKS cluster
const k8sProvider = new k8s.Provider('k8sProvider', {
    kubeconfig: kubeconfig,
});

// Use the existing Helm Chart for bitwarden_rs
const bitwardenChart = new k8s.helm.v3.Chart('bitwarden-rs', {
    chart: "bitwarden_rs",
    version: "1.2.3", // specify the version of the chart you want to deploy
    fetchOpts:{
        repo: "https://charts.your-repo.com", // replace with the repo URL where the chart is stored
    },
}, { provider: k8sProvider });

// Export the AKS cluster's kubeconfig and the public IP address to connect to Bitwarden
export const kubeConfigOutput = aksCluster.kubeConfigRaw;
export const bitwardenServiceIP = bitwardenChart.getResourceProperty('v1/Service', 'bitwarden-rs', 'status').apply(status => status.loadBalancer?.ingress[0].ip);
```

By executing this program with Pulumi, you will get an AKS cluster running `bitwarden-rs` accessible via the outputted IP address. Make sure to replace placeholder values like `YOUR_SSH_PUBLIC_KEY_HERE`, `YOUR_SERVICE_PRINCIPAL_CLIENT_ID`, `YOUR_SERVICE_PRINCIPAL_CLIENT_SECRET`, and the chart `version` and `repo` URL as appropriate for your setup.

Please note that managing and securing Kubernetes and Helm charts involves additional considerations that are not covered in this brief example, such as setting up role-based access control (RBAC), managing secrets, and enabling network policies for security.
