Deploy the sync-qcloud-cdn-cert helm chart on Kubernetes
TypeScriptDeploying a Helm chart with Pulumi involves using the
Chart
resource from Pulumi's Kubernetes package. Here, we are going to create a Pulumi program in TypeScript which deploys thesync-qcloud-cdn-cert
helm chart to a Kubernetes cluster. We assume you have already set up a Kubernetes cluster and have thekubeconfig
file available for Pulumi to interact with your cluster.To start, you will need to install the Pulumi CLI and the required NPM packages:
npm install @pulumi/kubernetes
Make sure to log in to Pulumi before running the program:
pulumi login
Now let's write the Pulumi program that deploys the Helm chart:
import * as k8s from "@pulumi/kubernetes"; // We will create a new Helm Chart resource. Pulumi will install the Helm chart in the default // namespace of the Kubernetes cluster that your `kubeconfig` points to. // Replace `repoUrl` with the actual repository URL where the Helm chart is located const repoUrl = "https://charts.example.com/"; const cdnCertChart = new k8s.helm.v3.Chart("sync-qcloud-cdn-cert", { chart: "sync-qcloud-cdn-cert", // The name of the chart to deploy // Here you should set the repository where your Helm chart is hosted fetchOpts: { repo: repoUrl, }, // You can specify additional configuration options for the chart here. // For example, you can set values corresponding to the chart's `values.yaml` file. // Suppose the chart accepts a `certFilePath` value to specify a custom cert path. // we'd set that like this (the `values` field below is illustrative, adjust as per the actual chart): values: { certFilePath: "/path/to/cert", // Add other configuration values here }, // If your chart requires a specific namespace, or you want to deploy it in a particular namespace, // specify the `namespace` field. By default, Pulumi uses the `default` namespace. // If you need to create a new namespace you can do so using k8s.core.v1.Namespace resource separately. namespace: "default", }); // When you run `pulumi up`, Pulumi will install the Helm chart onto your Kubernetes cluster
To execute this Pulumi program, you would typically run the following commands:
pulumi stack init
to create a new stack for your project if you haven't already.pulumi up
to stand up your infrastructure according to the Pulumi program you've written.
Key Points:
- The program imports the Pulumi Kubernetes SDK for TypeScript.
- We instantiate a
Chart
resource with configurations specific to oursync-qcloud-cdn-cert
needs. - The
chart
field is the name of the Helm chart, andfetchOpts.repo
should be the URL of the Helm repository where your chart exists. - The
values
object is equivalent to customizing your Helm chart'svalues.yaml
file. You specify the specific configuration needed for your setup there. - We use the
default
namespace for deployment, but this can be changed based on your requirements. - Make sure to replace the placeholder values such as
repoUrl
,certFilePath
, and any other values with the appropriate values for your use case.
Remember that Helm charts and Kubernetes have many nuances and there's a lot that can be customized, so be sure to refer to the documentation of the specific helm chart for more details. You can always consult the Pulumi and the Kubernetes documentation for deeper insight into how these tools work.
