Deploy the swaggereditor helm chart on Kubernetes
TypeScriptTo deploy the Swagger Editor on a Kubernetes cluster using a Helm chart with Pulumi, we are going to use the
kubernetes.helm.v3.Chart
resource from the Kubernetes provider. This resource allows us to deploy Helm charts in a Kubernetes cluster in a declarative way using Pulumi and TypeScript.Below, you will find a Pulumi program written in TypeScript that performs the following actions:
- It creates a new Helm chart resource named
swagger-editor
. - It specifies the chart to deploy (
swaggereditor/swaggereditor
) from the specified Helm repo (https://charts.helm.sh/stable
). - It sets the release name to
swagger-editor
which is how the deployed resources will be labeled and identified within the Kubernetes cluster. - It uses the default namespace for deployment.
Please make sure that you have Helm installed on your local machine and that you have access to a Kubernetes cluster where you can deploy the chart.
Here's how the Pulumi program looks:
import * as k8s from "@pulumi/kubernetes"; // Create an instance of the Swagger Editor Helm chart. const swaggerEditorChart = new k8s.helm.v3.Chart("swagger-editor", { chart: "swaggereditor/swaggereditor", version: "3.35.2", // Replace with the desired chart version fetchOpts: { repo: "https://charts.helm.sh/stable", }, }, { provider: k8sProvider }); // Ensure you have a configured Kubernetes provider // Export the base URL for the Swagger Editor export const swaggerEditorUrl = swaggerEditorChart.getResource("v1/Service", "swagger-editor").status.apply(status => { if (status.loadBalancer.ingress) { // If your service is exposed via a LoadBalancer, use the following: return `http://${status.loadBalancer.ingress[0].ip}`; } else { // If LoadBalancer is not used, you might want to handle exposing the service differently. return "Service is not exposed via a LoadBalancer."; } });
Explanation:
- First, we import the necessary Pulumi Kubernetes package.
- We create a new Helm chart instance using
new k8s.helm.v3.Chart
. This instance is representative of the Swagger Editor Helm chart.- The
chart
argument specifies the Helm chart to be deployed. Here we've used the chart's nameswaggereditor/swaggereditor
which should match what is specified in the Helm repository. - The
version
argument specifies the version of the chart to deploy. You should check the Helm repository for the Swagger Editor chart for available versions. - The
fetchOpts.repo
argument is the URL of the Helm repository containing the desired chart.
- The
- We assume that you have a Kubernetes provider already configured, since
k8sProvider
is referenced but not defined in the code. The provider is used to indicate to Pulumi which Kubernetes cluster to target for deployment. - Finally, we export the URL for accessing the deployed Swagger Editor. It's commented to reflect that one would need to adjust this based on how the service is exposed (e.g., using a LoadBalancer, NodePort, etc.).
After deploying this code with Pulumi, you would access the Swagger Editor through the returned
swaggerEditorUrl
, provided the relevant Kubernetes service is indeed exposed via a LoadBalancer. If not, you would address exposing the service according to your cluster setup.- It creates a new Helm chart resource named
