1. Deploy the pypi-server helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the pypi-server Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, you will first need to set up and configure Pulumi to communicate with your Oracle Cloud Infrastructure (OCI) and install the necessary Pulumi providers for OCI and Kubernetes.

    The Pulumi OCI provider will be used to interact with OCI to manage your OKE cluster, and the Pulumi Kubernetes provider will be used to deploy the Helm chart onto the OKE cluster.

    Here's a detailed explanation and Pulumi TypeScript program for deploying the pypi-server Helm chart on OKE:

    1. Install Pulumi CLI: You should start by installing Pulumi CLI on your machine if it's not already installed.
    2. Configure Oracle Cloud Access: After setting up the Pulumi CLI, you will need to configure Pulumi with your Oracle Cloud credentials to enable authentication.

    Now, let me walk through the Pulumi TypeScript code that carries out the deployment:

    1. Set up the OCI provider: Configure Pulumi to use the OCI provider. This provider will enable you to interact with the Oracle Kubernetes Engine.
    2. OKE Kubernetes Cluster: In this example, we assume the cluster is already provisioned, and we use its kubeconfig file to interact with it. If you need to provision a new OKE cluster, you would use resources like oci.ContainerEngine.Cluster.
    3. Helm Chart: We deploy the pypi-server Helm chart to the OKE cluster with the kubernetes.helm.v3.Chart resource.

    Here is a complete Pulumi program to deploy the pypi-server Helm chart:

    import * as pulumi from '@pulumi/pulumi'; import * as oci from '@pulumi/oci'; import * as k8s from '@pulumi/kubernetes'; // Create an Oracle Kubernetes Engine (OKE) instance // In this example, we assume the OKE cluster has already been created and have its kubeconfig. // Load the kubeconfig file from the existing OKE cluster const kubeconfig = pulumi.output(oci.containerengine.getClusterKubeconfig({ // Replace <Cluster_OCID> with the OCID of the existing OKE cluster clusterId: '<Cluster_OCID>', })); // Create a Kubernetes provider instance using the kubeconfig const k8sProvider = new k8s.Provider('okeK8sProvider', { kubeconfig: kubeconfig.result }); // Deploy pypi-server Helm chart to the OKE cluster const chart = new k8s.helm.v3.Chart('pypi-server-chart', { chart: 'pypi-server', // In case the chart is not in the default Helm repo, specify the 'repo' option // For example: repo: 'https://kubernetes-charts.storage.googleapis.com/', namespace: 'default', // Replace with the namespace where you want to deploy your app values: { // Specify the values for the Helm chart here // For example: // service: { // type: 'LoadBalancer', // }, // persistence: { // enabled: true, // size: '10Gi', // }, }, }, { provider: k8sProvider }); // Export the endpoint of the pypi-server export const pypiServerEndpoint = chart.getResourceProperty('v1/Service', 'default/pypi-server', 'status') .apply(status => status.loadBalancer.ingress[0].ip);

    When running this Pulumi program, Pulumi will:

    • Load the kubeconfig of your OKE cluster.
    • Create a Kubernetes provider that specifies the cluster where resources will be deployed.
    • Deploy the pypi-server Helm chart to your OKE cluster in the default namespace (or whichever namespace you specify).

    To initiate the deployment, you will run pulumi up in the directory containing this code, which will create a new Pulumi stack (if you haven't already), and apply the desired state specified by the code to your cloud infrastructure.

    Remember to replace <Cluster_OCID> with your actual OKE cluster OCID and customize the values field of the Helm chart with your desired configuration.

    The exported value pypiServerEndpoint provides you with the IP address of the load balancer, assuming the pypi-server service is set up to use a load balancer. If the service uses other means to expose itself, such as NodePort or Ingress, you'd retrieve the appropriate information in a similar manner.
