1. Deploy the flink-kubernetes-operator-crds helm chart on Kubernetes


    Deploying a Helm chart on a Kubernetes cluster involves creating a release that combines the Helm chart and the desired configuration into a manageable deployment unit. In this case, you want to deploy the flink-kubernetes-operator-crds Helm chart. This could be a Helm chart that contains custom resource definitions (CRDs) necessary for setting up a Flink operator on your Kubernetes cluster.

    To achieve this using Pulumi with TypeScript, we'll use the @pulumi/kubernetes package which allows us to leverage Kubernetes resources, including Helm charts.

    To begin, you'll need to install the Pulumi CLI and set up your Kubernetes cluster. Then, you need to install the Pulumi Kubernetes Package:

    $ npm install @pulumi/kubernetes

    Now, let's write a Pulumi program to deploy the Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes provider instance that uses our existing cluster context. const provider = new k8s.Provider("k8s-provider", { kubeconfig: "<YOUR_KUBECONFIG_HERE>", // Replace <YOUR_KUBECONFIG_HERE> with your kubeconfig file contents }); // Create a Helm Release for the flink-kubernetes-operator-crds chart const flinkOperatorCRDs = new k8s.helm.v3.Chart("flink-operator-crds", { chart: "flink-kubernetes-operator-crds", // Specify the Helm repository here: fetchOpts: { repo: "https://<REPOSITORY_URL>", // Replace <REPOSITORY_URL> with the Helm chart repo URL containing your chart }, }, { provider }); // Export the resources name of the Release export const flinkOperatorCRDsName = flinkOperatorCRDs.metadata.name;

    This is what each part of the program does:

    1. We import the @pulumi/kubernetes package to interact with Kubernetes.

    2. We create a Kubernetes provider instance using kubeconfig which should contain your cluster configuration. Make sure to replace <YOUR_KUBECONFIG_HERE> with the actual contents of your kubeconfig file.

    3. We define a new Helm chart release using k8s.helm.v3.Chart. The chart name provided is "flink-kubernetes-operator-crds" which will install the Flink operator CRDs on your cluster. Note that you need to replace <REPOSITORY_URL> with the actual Helm repository URL where the flink-kubernetes-operator-crds chart is located.

    4. An export line is there to show how to retrieve the name of the deployed resources once Pulumi has done its work.

    To apply this program, run pulumi up which will prompt you to review and confirm the deployment.

    Remember, be careful with any sensitive data such as kubeconfig contents – treat it like a password and keep it secure.

    The above code assumes that you have the Helm chart for the Flink Kubernetes Operator CRDs available in a repository. If this is an official Helm chart, the repository URL will be something provided by the creators of the Flink Kubernetes Operator. If it's a custom Helm chart, you would use the URL where your chart is hosted.

    After running the code with pulumi up, the Flink Kubernetes operator CRDs should be installed in your Kubernetes cluster, and you can then proceed to deploy the actual Flink Kubernetes operator and create Flink applications.
