Deploy the suitecrm helm chart on Google Kubernetes Engine (GKE)

Question

Pulumi · Accepted Answer

To deploy the SuiteCRM Helm chart on Google Kubernetes Engine (GKE), you'll need to perform several steps.

First, you need to create a GKE cluster where your application will be hosted. Then, you'll need to deploy the SuiteCRM Helm chart to this GKE cluster.

Here's what each of these steps involves:

1. **Creating a GKE Cluster**: This involves setting up a GKE cluster in your Google Cloud Platform (GCP) project. You'll need to define the properties of the cluster such as the machine type, the number of nodes, and other configurations.

2. **Deploying Helm Chart**: After setting up the GKE cluster, you need to install the SuiteCRM Helm chart to the Kubernetes cluster. Helm charts are packages of pre-configured Kubernetes resources.

Below is the Pulumi program in TypeScript to set up a GKE cluster and deploy a Helm chart for SuiteCRM.

### Installation

Before running this program, you will need to have Pulumi installed and set up along with the necessary Pulumi GCP provider. You'll also need `kubectl` and Helm installed for interacting with your Kubernetes cluster and to install Helm charts respectively.

Make sure you have authenticated with GCP with the necessary permissions to create and manage GKE clusters.

### Pulumi Program

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

// Create a GKE cluster.
const cluster = new gcp.container.Cluster("suitecrm-cluster", {
    initialNodeCount: 2,
    minMasterVersion: "latest", // Ensure you are using an up-to-date master version
    nodeVersion: "latest", // and node version for security and compatibility
    nodeConfig: {
        machineType: "n1-standard-1", // This is a cost-effective default machine type
        oauthScopes: [
            "https://www.googleapis.com/auth/cloud-platform",
        ],
    },
});

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

// Export the Kubeconfig for the GKE 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 a Kubernetes provider instance that uses our cluster from above.
const provider = new k8s.Provider("gke-k8s", {
    kubeconfig: kubeconfig,
});

// Deploy SuiteCRM Helm chart using the Kubernetes provider.
const suitecrmChart = new k8s.helm.v3.Chart("suitecrm", {
    chart: "suitecrm", // This chart name is assumed to be in the official Helm chart repository
    fetchOpts:{
        repo: "https://charts.bitnami.com/bitnami", // Replace with the appropriate Helm repo URL
    },
    version: "8.0.4", // Replace with the desired Chart version
    values: {
        // Define necessary values for your SuiteCRM chart
        // e.g., to enable ingress, you'd add the following:
        // ingress: { 
        //   enabled: true, 
        //   hostname: "suitecrm.yourdomain.com" 
        // },
        // Alternatively, you could use a separate values file and read the contents:
        // ...values: pulumi.all([pulumi.output(fs.readFileSync("values.yaml"))]),
    },
}, { provider: provider });

// Export the Helm Chart name
export const suitecrmChartName = suitecrmChart.name;
```

In the program:

- A GKE cluster is set up with a minimum of 2 nodes using the `n1-standard-1` machine type, which balances cost and capacity. This cluster is established in the default configuration with OAuth scopes allowing full access but limited to the cluster by GCP IAM.
- The Kubeconfig needed to access the cluster from your local machine is exported. This can be used with `kubectl` to interact with your GKE cluster.
- A Kubernetes Provider is created, which specifies that Pulumi commands should interact with this newly-created GKE cluster.
- Finally, the SuiteCRM Helm chart is deployed using the Kubernetes Provider. The chart name and version correspond to the SuiteCRM chart you want to deploy. Ensure that you specify the correct repository URL and version to use.

You can run this Pulumi program using:

```bash
pulumi up
```

After confirming the preview, Pulumi will execute the plan and create the resources.

Once deployed, you can use `kubectl` (with the generated Kubeconfig) and `helm` to manage your application in the GKE cluster. You can find more configuration options for the SuiteCRM chart by searching for its documentation or using `helm show values bitnami/suitecrm`.
