1. Deploy the casdoor helm chart on Linode Kubernetes Engine


    To deploy the Casdoor Helm chart on the Linode Kubernetes Engine (LKE), we'll need to follow these steps:

    1. Set up a Kubernetes cluster in Linode: If you don't already have a Kubernetes cluster running in Linode, you'll need to create one. You can do this through the Linode Cloud Manager or by using Pulumi with the Linode provider.

    2. Install and configure kubectl: Ensure kubectl is installed and configured to connect to your LKE cluster. Linode provides a kubeconfig file that you can use to set up kubectl.

    3. Install Helm: Helm is a package manager for Kubernetes that simplifies the deployment of applications. Make sure Helm is installed and ready to go.

    4. Add the Casdoor Helm repository: You'll need to add the official Casdoor Helm repository to Helm so that you can install the chart.

    5. Deploy the Casdoor Helm chart: Once the Helm repository is added, you can deploy Casdoor by creating a new Helm release.

    Here's a TypeScript program using Pulumi that sets up the Casdoor Helm chart deployment assuming that you already have an LKE cluster and kubectl is configured:

    import * as k8s from "@pulumi/kubernetes"; // Define the Casdoor Helm chart release. const casdoorRelease = new k8s.helm.v3.Chart("casdoor", { // Specify the Helm chart repository and chart. repo: "casdoor", chart: "casdoor", // Define any custom values you want to pass into your Helm chart. // See the Helm chart documentation for Casdoor to understand what values are needed. values: { // Customize your Casdoor deployment here. // This is an example and will likely not work out-of-the-box // without the proper values set for your specific deployment needs. // Refer to the Casdoor Helm chart documentation for the complete list of values. }, }); // Export the public IP address of the Casdoor service, assuming LoadBalancer service type. export const casdoorPublicIP = casdoorRelease.getResourceProperty("v1/Service", "casdoor", "status") .apply(status => status.loadBalancer.ingress[0].ip);


    • We're importing the @pulumi/kubernetes package to interact with the Kubernetes cluster.
    • We're creating a new Chart resource with Pulumi, which corresponds to a Helm chart deployment. The repo and chart names need to be replaced with the actual Casdoor Helm chart repository and chart name.
    • Under values, you can specify the Helm chart values that configure the Casdoor application. These will include things like service settings, port numbers, image versions, and any other configurations that Casdoor supports through its chart.
    • Due to the dynamic nature of Kubernetes resources, we're exporting the public IP address by accessing the Kubernetes Service created by the Helm chart and retrieving the IP from the LoadBalancer's ingress.

    Before running this Pulumi program, you must replace the placeholder values within the values object with actual configuration values for the Casdoor Helm Chart. Please refer to the official Casdoor Helm chart documentation to find out what values you need to provide.

    To deploy the chart:

    1. Make sure Pulumi is installed and configured to connect to your Linode account.
    2. Install @pulumi/kubernetes with npm or yarn.
    3. Write the program above to a TypeScript file, e.g., index.ts.
    4. Run pulumi up to initiate the deployment process. If prompted, select yes to deploy the resources.

    Keep in mind that Helm value configurations can be quite extensive depending on the complexities of the application, so you should always start with the default setup recommended by the chart maintainers and incrementally update it to fit your specific needs.
