1. Deploy the flink-kubernetes-operator helm chart on Digital Ocean Kubernetes Service

    TypeScript

    To deploy the flink-kubernetes-operator Helm chart on Digital Ocean Kubernetes Service (DOKS), you'll need to follow these steps:

    1. Set up a DOKS Cluster: First, you'll need to have a Kubernetes cluster running in Digital Ocean. With Pulumi, you can create a new DOKS cluster or use an existing one. For the purpose of this explanation, we'll assume you have a cluster ready to go. If you need to create one, you can use the digitalocean.KubernetesCluster resource from Pulumi's DigitalOcean provider.

    2. Install the Helm Chart: Helm charts are packages that contain pre-configured Kubernetes resources. You can deploy these charts to your cluster with Pulumi's Kubernetes provider, which includes resources for working with Helm charts.

    3. Ensure Kubernetes Configurations: Make sure you have kubectl configured correctly to connect to your DOKS cluster. Pulumi uses the same configuration as kubectl to communicate with your Kubernetes cluster.

    Now, let's go through the Pulumi program in TypeScript that deploys the flink-kubernetes-operator Helm chart to your DOKS cluster. The program will include importing relevant packages, setting up the Helm chart resource, and deploying it to the cluster. Make sure you have Pulumi installed and you're logged into the Pulumi environment. You should also have node and npm (or yarn) installed to manage packages and run Pulumi commands.

    Here's a program that you can use to deploy the flink-kubernetes-operator Helm chart:

    import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; // Initialize a new Pulumi Kubernetes provider instance to communicate with Digital Ocean Kubernetes Service. // It uses the kubeconfig file created by Digital Ocean to authenticate and manage resources. const k8sProvider = new k8s.Provider('doks-k8s-provider', { kubeconfig: '<KUBECONFIG_CONTENT>', // Replace with the actual content of the kubeconfig file. }); // Deploy the flink-kubernetes-operator Helm chart. const flinkOperatorChart = new k8s.helm.v3.Chart('flink-operator-chart', { // The repository where the Helm chart is located. // If the chart is part of the official Helm repo, you may not need to provide this, // as Helm will use its default stable repo. repo: 'https://<HELM_CHART_REPO>', // Replace with the Helm chart repository URL. // The name of the chart to install. chart: 'flink-kubernetes-operator', // Specify the chart version to install. Omit this to install the latest version. version: '<CHART_VERSION>', // Replace with a specific chart version if needed. // Namespace to deploy the Helm chart into. // If omitted, Pulumi will deploy the chart to the default namespace. namespace: 'flink-operator', // Set to `true` if you want Pulumi to skip the installation if the chart is already installed. // This is useful when managing Helm chart deployments in automation and CI/CD systems. skipAwait: true, // Values to override from the default Helm chart values. // This would typically be used to customize the chart's default configuration. values: { // Custom values for the 'flink-kubernetes-operator' Helm chart. // Replace these with the actual values required for your Helm chart. }, }, { provider: k8sProvider }); // Associate this Helm chart deployment with the Kubernetes provider we initialized. // To access the Flink operator or any service it deploys, you might want to output the relevant service URL // or other data. Depending on your application and your cluster configuration, you can create a Pulumi output // for the necessary information. For instance: export const flinkOperatorServiceUrl = flinkOperatorChart.getResourceProperty( 'v1/Service', 'flink-operator', 'status' ).apply(status => status.loadBalancer.ingress[0].ip); // Now you can run `pulumi up` to deploy your Helm chart to the Digital Ocean Kubernetes Service cluster.

    Make sure to replace placeholder values such as <KUBECONFIG_CONTENT>, <HELM_CHART_REPO>, and <CHART_VERSION> with the actual values from your Digital Ocean and Helm chart configurations.

    Once you have your code ready:

    1. Run npm install to install the dependencies.
    2. Use pulumi stack init to create a new stack.
    3. Run pulumi up to deploy the Helm chart to your cluster.

    The flinkOperatorServiceUrl export at the end of the file will provide you with the IP address of the service once the Helm chart is deployed. You can use this IP to access the Flink operator.
