1. Deploy the egress helm chart on Kubernetes

    TypeScript

    To deploy an egress Helm chart on a Kubernetes cluster using Pulumi, we'll use the helm.sh/v3.Chart resource from the Kubernetes package. This resource allows you to specify a Helm chart from any repository or a local path, and Pulumi will handle the Helm chart release management.

    Here's an explanation of the steps we'll take in the program:

    1. Import the necessary Pulumi and Kubernetes packages.
    2. Define a Kubernetes Chart resource, specifying the Helm chart we want to deploy. In this case, the egress chart, which we'll presume is in a Helm repository.
    3. Pass in the chart values. If your egress chart requires specific values to configure egress rules or other settings, you can provide them in the values property.

    Below is a TypeScript program that demonstrates these steps. Make sure to replace <YOUR-CHART-NAME>, <CHART-VERSION>, <YOUR-REPO-URL>, and any values you want to customize for the chart:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // The name of the egress chart. Replace with the actual chart name. const egressChartName = "<YOUR-CHART-NAME>"; // The version of the chart you wish to install if not requiring the latest. const egressChartVersion = "<CHART-VERSION>"; // The repository URL where the chart can be found. const egressChartRepo = "<YOUR-REPO-URL>"; // Any custom values we want to specify for our chart. // Replace `key1`, `key2`, etc., with actual value keys and // provide the appropriate configuration corresponding to the egress chart. const egressChartValues = { key1: "value1", key2: "value2", // Add other custom values as needed }; // Deploy the egress chart. const egressChart = new k8s.helm.v3.Chart("egress", { repo: egressChartRepo, chart: egressChartName, version: egressChartVersion, values: egressChartValues, }); // Export the chart name export const chartName = egressChart.metadata.apply(meta => meta.name);

    In this program:

    • The k8s.helm.v3.Chart class refers to a Helm chart that resides in a Helm repository, specified by the repo parameter.
    • The repo, chart, version, and values fields are used to identify and configure the egress Helm chart. Customize the values passed to the values property to configure the egress settings your Helm chart requires.
    • We are exporting chartName, which is extracted from the metadata of the egressChart resource. This allows you to know the name assigned to your Helm chart in the cluster and can be used for referencing from other resources if needed.

    You will need to install the Pulumi CLI and configure it with the desired Kubernetes cluster where you want to deploy the chart. You can find instructions for installation and configuration in the Pulumi documentation.

    To run this Pulumi program, save it to a index.ts file, ensure you have node, npm, and the @pulumi/kubernetes package installed. Then, you can execute pulumi up to start the deployment process. Pulumi will show you a preview of the resources that will be created and ask for your confirmation before provisioning them in your Kubernetes cluster.
