Deploy the suitecrm helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the SuiteCRM Helm chart on a Kubernetes cluster using Pulumi, you will need to utilize the `kubernetes.helm.v3.Chart` resource from the Pulumi Kubernetes provider. This resource allows you to deploy Helm charts into a Kubernetes cluster.

Here are the steps involved:

1. **Setting up the Kubernetes Provider**: Pulumi uses providers to interact with different cloud services. In this case, you will use the Kubernetes provider to deploy workloads on a Kubernetes cluster.

2. **Creating a Helm Chart Resource**: You will use the `Chart` resource to deploy SuiteCRM. You need to specify the chart name, version, and optionally the values to customize the deployment. If the SuiteCRM chart is available in a public repository, you also need to specify the repository URL.

Below is a Pulumi program written in TypeScript that you could use to deploy the SuiteCRM Helm chart on a Kubernetes cluster. Before running this program, make sure you have Pulumi installed, access to a Kubernetes cluster, and that your kubeconfig is properly set up.

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

const suitecrmChart = new k8s.helm.v3.Chart("suitecrm", {
    chart: "suitecrm",
    version: "1.0.0", // Use the correct chart version here
    fetchOpts: {
        repo: "https://helm.loodse.com/", // Use the correct Helm repository here
    },
    values: {
        // Customize your SuiteCRM deployment with the necessary configuration 
        // This object should match the structure expected by the SuiteCRM Helm chart
        // Refer to the official SuiteCRM Helm chart documentation for the values schema
        persistence: {
            enabled: true,
            accessMode: "ReadWriteOnce",
            size: "8Gi",
        },
        service: {
            type: "ClusterIP",
            port: 80,
        },
        // ... other values can be added as needed
    },
});

// To access the SuiteCRM service, you might want to export its endpoint:
export const suitecrmServiceUrl = suitecrmChart.getResourceProperty("v1/Service", "suitecrm-suitecrm", "status").apply(status => `http://${status.loadBalancer.ingress[0].hostname}`);
```

This program performs the following actions:

- Imports the necessary Pulumi Kubernetes package.
- Creates a new instance of the `Chart` resource named `suitecrm`. This resource instructs Pulumi to deploy the SuiteCRM chart into your Kubernetes cluster.
- Sets the `chart` to `"suitecrm"`, which is the name of the chart in the Helm repository.
- Specifies the `version` and the repository URL under `fetchOpts.repo`. Make sure to use the correct version of the chart and the accurate URL to the repository hosting the SuiteCRM chart.
- The `values` object allows you to configure aspects of SuiteCRM, such as persistence settings for data storage and service settings for network access. You should adjust these values according to your needs and refer to the SuiteCRM Helm chart's documentation for a full list of configurable options.
- Optionally, the program exports the URL of the SuiteCRM Service, making it possible for you to access SuiteCRM from outside the cluster. However, this assumes the chart creates a `Service` of type `LoadBalancer` and you are running on a cloud provider that supports this and assigns a hostname or IP. If not, you may need to adjust the exported value accordingly.

To execute this program, you need to have Pulumi installed and set up.

Save this code in a file named `index.ts`, install the Pulumi CLI, and then run the following commands in your terminal:

```sh
pulumi up
```

This command starts the deployment process. Pulumi will show you a preview of the resources that will be created and prompt you for confirmation before proceeding.

Once everything is successfully deployed, if the service is exposed and depending on the settings you have selected in `values`, you might access SuiteCRM using the output from the `suitecrmServiceUrl`. If the service is not exposed directly (e.g., if using `ClusterIP` as a service type), you will need to use port-forwarding or similar to access the SuiteCRM application.

Keep in mind that the above code may need modifications to fit into your specific Kubernetes environment and the configuration that you want for SuiteCRM. Always refer to the SuiteCRM Helm chart documentation for detailed information on configuration options.
