1. Deploy the sftp-gcs helm chart on Rancher


    Deploying an SFTP server backed by Google Cloud Storage (GCS) involves setting up an SFTP service where the data is actually stored in a GCS bucket. The sftp-gcs Helm chart can simplify the deployment of this setup on Kubernetes clusters, including those managed by Rancher.

    To deploy the sftp-gcs Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you'll need the following:

    • A Rancher-managed Kubernetes cluster already set up and accessible.
    • The sftp-gcs Helm chart available in a Helm chart repository or your local filesystem.
    • The Pulumi programming model to declare infrastructure as code.

    Below is a Pulumi TypeScript program that demonstrates how you can deploy the sftp-gcs Helm chart to a Rancher-managed Kubernetes cluster:

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; import * as rancher2 from "@pulumi/rancher2"; // Initialize a Pulumi Kubernetes provider for the Rancher-managed cluster. // You must have the kubeconfig file for your Rancher cluster available. // The kubeconfig usually gets set up when you create a cluster with Rancher. // It specifies the necessary details to connect to the Kubernetes API of the cluster. const rancherK8sProvider = new kubernetes.Provider("rancher-k8s-provider", { kubeconfig: process.env.KUBECONFIG, // Ensure that KUBECONFIG is set in the environment variables }); // Deploying a Helm chart requires the Helm Release resource. // Here we are setting up the 'sftp-gcs' Helm chart. const sftpGcsHelmChart = new kubernetes.helm.v3.Release("sftp-gcs", { chart: "sftp-gcs", // This is the chart name, which should be available in your chart repository repositoryOpts: { repo: "https://your-helm-chart-repository.com/", // Replace with the URL of your Helm chart repository }, values: { // Here, you'll include the values required for 'sftp-gcs' chart. // For example, you may need to specify the GCS credentials, bucket details, and SFTP users. // Refer to the specific 'sftp-gcs' chart documentation for the full list of configurable values. }, }, { provider: rancherK8sProvider }); // Notice that we specify the rancherK8sProvider // The output that provides the status of the Helm Release. export const sftpGcsStatus = sftpGcsHelmChart.status;

    Please ensure the following before you run this Pulumi program:

    • Replace "https://your-helm-chart-repository.com/" with the actual repository URL where the sftp-gcs Helm chart is located.
    • Replace the values with your specific configuration according to the sftp-gcs Helm chart documentation.
    • Ensure the environment variable KUBECONFIG is set with the path to your kubeconfig file, which holds the connection information for the Kubernetes cluster managed by Rancher.

    In this program, @pulumi/kubernetes is used as a provider for Kubernetes resources and allows Pulumi to work with Kubernetes objects. @pulumi/rancher2 is used for resources related to Rancher 2.x, though we're not directly using any specific Rancher resource in this example.

    The helm.v3.Release resource is a Pulumi resource that represents a Helm chart release within a Kubernetes cluster. Here, it's used to deploy the sftp-gcs Helm chart.

    Once you configure and run this Pulumi program, it will reach out to your Rancher-managed Kubernetes cluster and deploy the SFTP service backed by GCS as specified in the Helm chart.
