Deploy the ToolJet helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the ToolJet helm chart on Kubernetes using Pulumi, we will be using the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider. This resource allows us to deploy Helm charts into a Kubernetes cluster.

Before you proceed, ensure that you have the following prerequisites:

1. Pulumi CLI installed.
2. Kubernetes cluster access configured for `kubectl`.
3. Helm chart repository containing ToolJet chart is known and accessible.

Here is a Pulumi TypeScript program which will deploy the ToolJet helm chart on a Kubernetes cluster:

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

// Define the settings for the ToolJet Helm chart
const toolJetChart = new k8s.helm.v3.Chart("tooljet", {
    // This assumes that the ToolJet chart is available in the 'default' repository
    // If the chart is in a custom repository, you may need to add the `repo` property with the repository URL
    chart: "tooljet",
    // Specify the namespace where you want to deploy the ToolJet chart
    // If this namespace does not exist, it will be created as part of the deployment process
    namespace: "tooljet-namespace",
    // Here we define the values that we want to override from the default Helm chart values
    // These values will depend on what options the ToolJet Helm chart supports
    values: {
        // For example, if the Helm chart allows you to specify a service type, you can do it like so:
        // service: {
        //     type: "ClusterIP"
        // }
        // Repeat this pattern for any other values you wish to set or override
        // Please refer to the ToolJet chart's documentation for the full list of configurable options
    }
});

// Export the base URL for the ToolJet application
// This assumes that the Helm chart exposes a service through which the application can be accessed
// The exact details of how to obtain the URL will depend on the service type and cluster configuration
export const toolJetUrl = toolJetChart.getResourceProperty("v1/Service", "tooljet-service", "status").apply(status => {
    // Assuming the service type is LoadBalancer and your cloud provider provisions an external IP for it
    const ingress = status.loadBalancer.ingress[0];
    return ingress.ip || ingress.hostname;
});
```

This program creates an instance of the ToolJet Helm chart in a specific namespace with optional overridden values. You will need to replace these placeholders with actual values based on the chart's configuration parameters. The example assumes a LoadBalancer service type that your cloud provider supports. If the service type or architecture is different, adapt the `getResourceProperty` lookup accordingly.

To run this code:

1. Save the code above to a file, for example `index.ts`.
2. Run `pulumi up` to execute the code using Pulumi. This command will show you a preview of the resources Pulumi will create or modify.
3. Confirm the deployment by selecting `yes` when prompted by the Pulumi CLI.

This will deploy the ToolJet application to your Kubernetes cluster, as defined by the Helm chart.
