Deploy the schema-registry-ui helm chart on Google Kubernetes Engine (GKE)

Question

Pulumi · Accepted Answer

To deploy the `schema-registry-ui` Helm chart on Google Kubernetes Engine (GKE), you would need to take the following steps:

1. **Set up a GKE Cluster**: First, you will need a running GKE cluster. If you don't have a cluster already, you would need to create one.

2. **Install the Helm Chart**: Once you have your Kubernetes cluster, you can use Pulumi's Kubernetes provider to deploy the Helm chart for `schema-registry-ui`.

Below is a Pulumi TypeScript program that demonstrates how you can create a GKE cluster and deploy the `schema-registry-ui` Helm chart on it. This program uses `@pulumi/gcp` to create the GKE cluster and `@pulumi/kubernetes` to deploy the Helm chart.

Make sure you have Pulumi installed and configured with your Google Cloud credentials. You will also need to have `kubectl` configured to interact with your GKE cluster.

Here's the Pulumi program in TypeScript:

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

// Create a GKE cluster
const cluster = new gcp.container.Cluster("my-gke-cluster", {
    initialNodeCount: 2,
    minMasterVersion: "latest",
    nodeVersion: "latest",
    nodeConfig: {
        machineType: "n1-standard-1",
        oauthScopes: [
            "https://www.googleapis.com/auth/compute",
            "https://www.googleapis.com/auth/devstorage.read_only",
            "https://www.googleapis.com/auth/logging.write",
            "https://www.googleapis.com/auth/monitoring"
        ],
    },
});

// Export the Cluster name
export const clusterName = cluster.name;

// Export the Kubeconfig to access the Cluster
export const kubeconfig = pulumi.
    all([cluster.name, cluster.endpoint, cluster.masterAuth]).
    apply(([name, endpoint, masterAuth]) => {
        const context = `${gcp.config.project}_${gcp.config.zone}_${name}`;
        return `apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: ${masterAuth.clusterCaCertificate}
    server: https://${endpoint}
  name: ${context}
contexts:
- context:
    cluster: ${context}
    user: ${context}
  name: ${context}
current-context: ${context}
kind: Config
preferences: {}
users:
- name: ${context}
  user:
    auth-provider:
      config:
        cmd-args: config config-helper --format=json
        cmd-path: gcloud
        expiry-key: '{.credential.token_expiry}'
        token-key: '{.credential.access_token}'
      name: gcp
`;
    });

// Create the Kubernetes provider using the generated kubeconfig
const k8sProvider = new k8s.Provider("gkeK8s", {
    kubeconfig: kubeconfig,
});

// Deploy the schema-registry-ui helm chart
const schemaRegistryUi = new k8s.helm.v3.Chart("schema-registry-ui", {
    chart: "schema-registry-ui",
    version: "1.0.0", // Specify the chart version you want to deploy
    fetchOpts:{
        repo: "https://helm repo where schema-registry-ui is located",
    },
    // Specify the values or parameters for the Helm chart
    values: {
        /* Add any specific values here */
    },
}, { provider: k8sProvider });

// Export the schema-registry-ui service endpoint
export const schemaRegistryUiEndpoint = schemaRegistryUi.getResourceProperty("v1/Service", "schema-registry-ui", "status")
    .apply(status => status.loadBalancer.ingress[0].ip);
```

Here's what each part of the program does:

- The `gcp.container.Cluster` resource creates a new GKE cluster with the specified configuration.
- The `kubeconfig` is a computed string that will allow us to interact with the GKE cluster using `kubectl`.
- The `k8s.Provider` resource is used to initialize the Kubernetes provider with the kubeconfig from the GKE cluster we created.
- The `k8s.helm.v3.Chart` resource is used to deploy the `schema-registry-ui` Helm chart. In the `version` field, you should specify the version number of the Helm chart that you want to use, and in the `repo` field, you would need to specify the URL of the Helm repository where `schema-registry-ui` is hosted.
- If you have specific values or configurations for the Helm chart, you can provide them in the `values` object. These could include things like the port number that `schema-registry-ui` should use or any other configuration specific to your setup.

To deploy this Pulumi program, save it to a file called `index.ts`, then you can run `pulumi up` to create the resources. After the command completes, Pulumi will output the endpoint of the `schema-registry-ui` service.

Remember to provide the actual Helm chart repository URL in the `repo` field where the `schema-registry-ui` chart is located.

Please ensure you check the Helm chart documentation for `schema-registry-ui` for any specific configurations you may need to add.
