Deploy the nocodb helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the nocodb Helm chart on Kubernetes using Pulumi, you'll write a program that leverages Pulumi's Kubernetes package. You'll create a Helm chart resource, which tells Pulumi to install a Helm chart into your Kubernetes cluster.

Helm is a package manager for Kubernetes that allows you to define, install, and upgrade even the most complex Kubernetes applications. NocoDB is an open-source platform that turns any database into a smart spreadsheet, and it's available as a Helm chart.

In the Pulumi program below, we will:

1. Import the necessary Pulumi and Kubernetes packages.
2. Create an instance of a Helm Chart resource to deploy nocodb.
3. Set the appropriate configuration values for the Helm Chart if needed.

Here is the TypeScript program:

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

// Create a Kubernetes namespace for nocodb if you want to isolate it to a particular namespace.
const namespace = new k8s.core.v1.Namespace("nocodb-namespace", {
  metadata: {
    name: "nocodb",
  },
});

// Deploy nocodb using a Helm Chart.
const nocodbChart = new k8s.helm.v3.Chart("nocodb", {
  chart: "nocodb",
  version: "0.1.0", // Specify the version of the Helm chart.
  namespace: namespace.metadata.name, // Deploy the chart in the created namespace
  // If you have custom values, you can specify them here. For example:
  /*
  values: {
    persistence: {
      size: "2Gi",
    },
  },
  */
}, { provider: k8sProvider }); // Specify the k8s provider if it's not the default one.

// Export the namespace name.
export const namespaceName = namespace.metadata.name;
```

Here's what each significant piece of the program does:

- The `namespace` variable is an instance of a Kubernetes namespace where the chart will be deployed. This namespace creation is optional, and if not included, you could deploy the Helm chart in the default namespace or any other existing one.
- `nocodbChart` is an instance of `k8s.helm.v3.Chart`, which represents a Helm chart deployment in Pulumi. The properties we set include:
  - `chart`: The name of the chart to deploy, which is `nocodb` in this case.
  - `version`: The version of the Helm chart you intend to deploy (you should check the Helm repository for the current version).
  - `namespace`: The namespace where the Helm chart will be deployed. We reference the `namespace` we created above using `namespace.metadata.name`.
  - `values`: A placeholder for any custom values you wish to provide to the Helm chart. These values override the default settings in the Helm chart, but in this code we have commented them out.
- We've referenced `k8sProvider`, which is an instance of a Kubernetes provider. If you have a specific Kubernetes provider configuration (for example, if you are running against a non-default context or cluster), you would use this to inform Pulumi how to communicate with your cluster. If you're working with the default configuration context in your kubeconfig file, you may omit the `provider` field.
- The `export` line at the end of the file is there to export the name of the namespace created for the nocodb deployment, which can be helpful when querying Kubernetes about the resources Pulumi manages.

Remember to install the Pulumi CLI and the Kubernetes Pulumi package if you haven't already, and set up your Kubernetes cluster configuration context so that Pulumi may access it. You will also need to have Helm installed and configured.

You can run this program with the Pulumi CLI by navigating to the directory containing this program and executing `pulumi up`. After confirming the resource creation details listed by the Pulumi CLI, the resources will be created in your Kubernetes cluster.
