1. Deploy the mojaloop helm chart on Digital Ocean Kubernetes Service

    TypeScript

    To deploy the Mojaloop helm chart on the Digital Ocean Kubernetes Service (DOKS) using Pulumi, you'll need to perform the following high-level steps:

    1. Create a new Kubernetes cluster in Digital Ocean.
    2. Configure your Pulumi environment to communicate with the newly created cluster.
    3. Use the Helm Chart resource in Pulumi to deploy Mojaloop to the cluster.

    Please ensure that you have installed Pulumi on your local machine and have set up the Digital Ocean provider with the necessary access tokens.

    Here is how you can achieve the deployment with a Pulumi TypeScript program:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("mojaloop-cluster", { region: digitalocean.Regions.SFO2, // For example, San Francisco 2, choose the region closest to you version: "latest", // Use the latest available version of Kubernetes nodePool: { name: "default", size: digitalocean.DropletSlugs.DropletS2VCPU2GB, // Choose the droplet size based on your requirements nodeCount: 2, // Specify the number of nodes in the node pool }, }); // Use the created cluster's kubeconfig to interact with the cluster const provider = new kubernetes.Provider("do-k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the Mojaloop helm chart const mojaloopChart = new kubernetes.helm.v3.Chart("mojaloop-chart", { chart: "mojaloop", // Specify the Mojaloop helm chart repository URL if it's not located in the default helm repo fetchOpts: { repo: "https://helm.mojaloop.io/", // Replace with the correct helm chart repo if different }, // Set values for the helm chart as required, for example: values: { // ... Mojaloop specific helm chart values ... // You can set any value that the Mojaloop chart expects here. // For example, you might need to specify database connection details, // service types, replica counts, etc. }, }, { provider }); // Ensure to pass the provider we initialized with the DigitalOcean cluster's kubeconfig // Export the kubeconfig and the cluster's endpoint to connect to your cluster using kubectl or other tools export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const clusterEndpoint = cluster.endpoint;

    Make sure to replace the placeholder values with the actual values that are appropriate for your use case. For example, select the region where you want your cluster to be deployed, and choose the Kubernetes version and nodePool specifications according to your application's requirements.

    Explanation:

    1. We create a new DOKS cluster by instantiating digitalocean.KubernetesCluster. Here, you specify the region, Kubernetes version, and droplet sizes suitable for Mojaloop along with the desired node count.

    2. Next, we use that cluster's kubeconfig to set up a new Pulumi K8s Provider. This provider will be used to manage Kubernetes resources within the created cluster.

    3. Then, we deploy Mojaloop using the helm.v3.Chart resource. We specify the chart and repo where the Helm chart can be found. Optionally, we can also provide values to customize the Helm chart deployment to our needs.

    Once this program is executed, Pulumi will provision the cluster and then deploy the Mojaloop helm chart on it. After the deployment, you can interact with your Kubernetes cluster by using the exported kubeconfig with tools like kubectl.

    Please replace the Helm chart repository URL and values with those specific to the mojaloop helm chart you wish to deploy. Lastly, review and adjust the node sizes and counts to match your expected workload.

    Remember that any sensitive values or those you might want to change frequently should ideally be managed through Pulumi configuration or environment variables, rather than being hard-coded in your Pulumi program.
