1. Deploy the fluentd-kubernetes-daemonset helm chart on Azure Kubernetes Service (AKS)


    To deploy the fluentd-kubernetes-daemonset Helm chart on an Azure Kubernetes Service (AKS) cluster with Pulumi, you would typically perform the following steps:

    1. Create an AKS cluster.
    2. Configure kubectl to connect to the AKS cluster.
    3. Use the Helm Chart resource in Pulumi to deploy fluentd-kubernetes-daemonset.

    Below is a Pulumi program in TypeScript that demonstrates these steps. This program uses the @pulumi/azure-native and @pulumi/kubernetes packages. The azure-native package provides resources that map directly to the Azure API, and the kubernetes package is used for deploying resources to a Kubernetes cluster, like the Helm chart in this case.

    First, ensure that you have the necessary Pulumi and provider packages installed:

    npm install @pulumi/pulumi @pulumi/azure-native @pulumi/kubernetes

    Now, let's go through the program that would deploy fluentd-kubernetes-daemonset in an AKS cluster:

    import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Create an AKS cluster. // Replace the following parameters with your own desired settings. const resourceGroupName = new azure.resources.ResourceGroup("resourceGroup"); const managedCluster = new azure.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroupName.name, // Additional required parameters like location, dnsPrefix, agentPoolProfiles, etc. // must be filled out according to your specific infrastructure needs. }); // Export the kubeconfig to connect to the AKS cluster. export const kubeconfig = pulumi. all([managedCluster.name, resourceGroupName.name]). apply(([clusterName, rgName]) => azure.containerservice.listManagedClusterUserCredentials({ resourceName: clusterName, resourceGroupName: rgName, })).apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()); // Step 2: Configure kubectl to connect to the AKS cluster. // The kubeconfig created above is used by the k8s provider to deploy Helm charts. const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Step 3: Use the Helm chart resource to deploy fluentd-kubernetes-daemonset. const fluentdHelmChart = new k8s.helm.v3.Chart("fluentd-helm-chart", { chart: "fluentd-kubernetes-daemonset", version: "1.12.3", // Replace this with the desired chart version. fetchOpts: { repo: "https://fluent.github.io/helm-charts", }, }, { provider: k8sProvider }); // Optionally, you may want to export a Helm chart resource attribute. // It might be the status of the deployment, the name of the service, or any other useful information. export const fluentdChartStatus = fluentdHelmChart.status;

    What the program does:

    • Step 1: It creates an AKS cluster inside the specified resource group. You need to provide values for the location, dnsPrefix, agentPoolProfiles, and any other configuration specific to your requirements that aren't covered in this generic example.

    • Step 2: It exports the kubeconfig which is used to communicate with your AKS cluster. This kubeconfig is then utilized by the k8s.Provider which sets up the Pulumi Kubernetes provider to communicate with your AKS cluster.

    • Step 3: It deploys the fluentd-kubernetes-daemonset Helm chart to the AKS cluster using the Pulumi k8s.helm.v3.Chart resource. This part of the code fetches the Helm chart from the specified Helm repo and deploys it to your cluster.

    Lastly, it exports the status of the Helm chart deployment, which can be observed in the Pulumi console or by using CLI commands.

    To run this program, save it to a file (e.g., index.ts), and execute it using the Pulumi CLI with the following commands:

    pulumi stack init fluentd-on-aks pulumi up

    When prompted, review the changes and select yes to deploy the stack. After running, you will get outputs from Pulumi including the kubeconfig and optionally the fluentdChartStatus showing the deployment status of the Helm chart.
