Deploy the casdoor helm chart on Kubernetes

Question

Pulumi · Accepted Answer

In order to deploy the Casdoor Helm chart on Kubernetes using Pulumi, we will need to use the Chart resource from the @pulumi/kubernetes package. This package enables us to operate on Kubernetes resources within our Pulumi program.

Here’s what the steps will generally look like:

Import necessary packages: We'll import the @pulumi/kubernetes package to deploy Helm charts.
Instantiate the Kubernetes Provider: Although not always required explicitly, we may need to create an instance of the Kubernetes provider if we're targeting a specific cluster context or need to configure the provider beyond the defaults.
Deploy the Helm Chart: Using the Chart resource, we can deploy the Casdoor Helm chart. The Chart resource will need the name of the chart and optionally, the chart version, any custom values used for configuration, the repository where the chart is hosted, and the namespace to deploy into if not default.

Let’s implement it:

import * as k8s from "@pulumi/kubernetes";

// Create a Kubernetes provider instance if necessary (e.g., different context, configuration)
// const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: "<YOUR_KUBECONFIG_CONTENT_HERE>" });

// Deploy the casdoor helm chart
const casdoorChart = new k8s.helm.v3.Chart("casdoor", {
    chart: "casdoor",
    // If you need to specify the version of the chart, un-comment and update the following line
    // version: "<CHART_VERSION>",
    // If the chart is not from the default Helm repository, you must specify `repo` as well.
    // For example, if it's a Helm chart hosted on `https://charts.casdoor.com`, you would include:
    // repo: "https://charts.casdoor.com",
    // Specify any custom values needed for the chart
    values: {
        // ... your custom values here ...
    },
    // Define the namespace to deploy into; default is "default"
    namespace: "casdoor-namespace",
}, { /* provider: k8sProvider */ }); // Specify the provider if you have instantiated it

// Optional: Export the status URL or other useful information
export const statusUrl = casdoorChart.status.apply(status => status?.urls?.join(", "));

This program will deploy the Casdoor application on a Kubernetes cluster using its Helm chart. If the chart is in a custom repository, you will need to replace the commented-out repo line with the chart's repository URL.

The values object within the Chart resource should be modified to match the specific configuration you desire for Casdoor. You would input any necessary Casdoor configuration settings here.
The namespace field specifies the Kubernetes namespace into which you'd like to deploy Casdoor. If this namespace doesn't exist, you'll need to create it with Pulumi or manually before deploying the chart.
The optional provider argument can be enabled and pointed to a k8s.Provider instance if you're working with a specific Kubernetes cluster that requires a specific configuration (not using the default).
The line export const statusUrl is an example of how to export the deployment's status URL. This is useful for accessing Casdoor after it's up and running.

Remember to replace placeholders like "<CHART_VERSION>" or `"<YOUR_KUBECONFIG_CONTENT_HERE>"
