1. Deploy the argo-workflow helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the Argo Workflows Helm chart on Oracle Kubernetes Engine (OKE), you'll be using a few components with Pulumi:

    1. Oracle Kubernetes Engine (OKE) Cluster: First, you need an OKE cluster where Argo Workflows will be deployed. If you already have one, you can connect Pulumi to it; if not, you would have to create one. In this program, we will assume that the cluster already exists.

    2. Helm Chart: Helm is a package manager for Kubernetes, which allows you to define, install, and upgrade even the most complex Kubernetes applications. Helm charts are packages of pre-configured Kubernetes resources.

    3. Pulumi Kubernetes Provider: Pulumi's Kubernetes provider, which allows you to interact with your Kubernetes clusters and deploy applications to them.

    Here's a TypeScript program that achieves the goal. We'll use the kubernetes and oci packages. Note that you'll need to configure Pulumi with your OCI credentials and have kubectl configured to communicate with your OKE cluster.

    import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; // Ensure you have kubectl configured to point to your OKE cluster. // The provider will use the current context from your kubeconfig file. const provider = new k8s.Provider('oke-provider', {}); // Deploy the Argo Workflows Helm chart to the OKE cluster. // Replace `<version>`, `<namespace>` and other configuration details as necessary. const argoWorkflows = new k8s.helm.v3.Chart('argo-workflows', { chart: 'argo-workflows', version: '<version>', // Specify the version of the chart you wish to deploy namespace: '<namespace>', // Specify the namespace where Argo Workflows should be installed fetchOpts:{ repo: 'https://argoproj.github.io/argo-helm', // The Helm repository where the chart is located }, }, { provider }); // Export the necessary resources export const argoWorkflowsName = argoWorkflows.metadata.apply(m => m.name);

    In this program:

    • We import the necessary Pulumi libraries for Kubernetes.
    • We set up a Kubernetes provider to interact with the OKE cluster.
    • We deploy the Argo Workflows Helm chart by creating an instance of Chart from the Pulumi Kubernetes (k8s) library, specifying the chart name (argo-workflows), version, namespace, and Helm repo URL.
    • We export the name of the release so you can easily reference it.

    You would replace <version> and <namespace> with appropriate values for your environment. The version is the version number of the Argo Workflows Helm chart, and namespace is the Kubernetes namespace where you want to deploy Argo Workflows.

    Please make sure you have installed Pulumi and configured it with OCI, and you have your kubeconfig pointing to your Oracle Kubernetes Engine's cluster context.

    Here's the documentation for the OCI Pulumi provider: OCI Container Engine for Kubernetes.

    To run this program, you will execute the following commands in your terminal:

    1. Navigate to the directory containing your Pulumi program file (index.ts in this case).
    2. Run pulumi up to preview and deploy the changes.

    Ensure that pulumi up completes successfully, which will indicate that Argo Workflows have been deployed to your OKE cluster. You can then interact with Argo using kubectl and start defining and running your workflows.
