1. Deploy the istio-egress-gateway helm chart on Rancher


    To deploy the Istio Egress Gateway Helm chart on a Rancher-managed Kubernetes cluster, you would take the following steps. This involves using the Pulumi Rancher2 provider to interact with Rancher and deploying the Helm chart into the Kubernetes cluster managed by Rancher.

    Here's a step-by-step explanation of the code below:

    1. Import the necessary Pulumi packages.
    2. We fetch the cluster where you want to deploy the Helm chart.
    3. We configure Rancher to deploy Istio Egress Gateway into the specified cluster.
    4. Output the information needed to interact with the gateway, such as the endpoints or names.

    Before running the code below, make sure Pulumi is installed and set up to authenticate with Rancher and your cloud provider. You also need to have the cluster ID and namespace where you want to deploy the Helm chart, and you should have the Helm chart information (like the repository URL, chart version, etc.) at hand.

    Here is the TypeScript program:

    import * as pulumi from '@pulumi/pulumi'; import * as rancher2 from '@pulumi/rancher2'; import * as k8s from '@pulumi/kubernetes'; // Replace with the ID of the Rancher-managed cluster where you want to deploy. const clusterId = 'your-cluster-id'; // Replace with the namespace where you want to deploy the Istio Egress Gateway. const namespace = 'istio-system'; // Fetching the Rancher cluster object const cluster = new rancher2.Cluster('my-cluster', { // Specify other cluster properties as needed // ... }); // Use existing Rancher cluster with Kubernetes provider const k8sProvider = new k8s.Provider('k8s', { kubeconfig: cluster.kubeConfig, }); // Deploy Istio Egress Gateway with Helm chart const istioEgressGateway = new k8s.helm.v3.Chart('istio-egress', { chart: 'istio-egressgateway', version: '1.8.0', // Use the version of the Helm chart you want to deploy fetchOpts: { repo: 'https://istio-release.storage.googleapis.com/charts', // Use the correct Helm repo }, namespace: namespace, }, { provider: k8sProvider }); // Exporting the information necessary to interact with the deployed Helm chart export const istioEgressGatewayName = istioEgressGateway.metadata.apply(m => m.name); export const istioEgressGatewayNamespace = istioEgressGateway.metadata.apply(m => m.namespace);

    Keep in mind that you need to customize the placeholders ('your-cluster-id' and 'istio-system', and optionally the chart version and repository) according to your setup.

    This code assumes that your Rancher-managed cluster is already set up and configured to use with Pulumi. The chart name 'istio-egressgateway' and the repository URL 'https://istio-release.storage.googleapis.com/charts' might need to be changed based on the actual names and URLs used by the Istio Helm charts. Also, ensure that the chart version ('1.8.0') matches with the one you wish to install.

    The chart and the namespace are referenced from the Pulumi Kubernetes provider, which is created using the kubeconfig from the fetched Rancher cluster. This sets up the connection to your Kubernetes cluster managed by Rancher, ready for the Istio Egress Gateway to be deployed.

    After running the Pulumi program, it will handle the deployment, and you can access the exported variables to find the name and namespace of your Istio Egress Gateway deployment.
