1. Deploy the docker-gc helm chart on Azure Kubernetes Service (AKS)


    To deploy the docker-gc Helm chart on Azure Kubernetes Service (AKS), you would need to perform several steps which include:

    1. Creating an AKS cluster using Pulumi.
    2. Setting up Helm and Tiller (if not using Helm v3 since Tiller is removed in Helm v3).
    3. Deploying the docker-gc chart to the AKS cluster.

    Pulumi provides a resource called Chart from the kubernetes package that lets you deploy Helm charts to a Kubernetes cluster. We will use this resource to deploy the docker-gc Helm chart to an AKS cluster.

    First, you'll need to install the necessary Pulumi packages. You can do this by running the following commands in your terminal:

    pulumi plugin install resource azure-native 2.11.0 pulumi plugin install resource kubernetes 4.4.0

    Here's a Pulumi program in TypeScript that sets up an AKS cluster and deploys the docker-gc Helm chart to it:

    import * as azure from "@pulumi/azure"; import * as azuread from "@pulumi/azuread"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create an Azure Resource Group const resourceGroup = new azure.core.ResourceGroup("aksResourceGroup", { location: "WestUS", // You can change the location to your preferred Azure region }); // Create an Azure AD Application for AKS const aksApp = new azuread.Application("aksApp", {}); // Create a Service Principal for the AD Application const aksSp = new azuread.ServicePrincipal("aksSp", { applicationId: aksApp.applicationId, }); // Create the Service Principal Password const aksSpPassword = new azuread.ServicePrincipalPassword("aksSpPassword", { servicePrincipalId: aksSp.id, endDate: "2099-01-01T00:00:00Z", }); // Create an AKS cluster const k8sCluster = new azure.containerservice.KubernetesCluster("aksCluster", { resourceGroupName: resourceGroup.name, location: resourceGroup.location, // The dnsPrefix here is a unique DNS prefix where your management APIs will be exposed. // It must be unique across Azure and contain between 3 and 31 characters, 'a'-'z', '0'-'9', and '-' dnsPrefix: "unique-prefix", defaultNodePool: { name: "aksagentpool", nodeCount: 2, vmSize: "Standard_DS2_v2", }, identity: { type: "SystemAssigned", }, servicePrincipal: { clientId: aksApp.applicationId, clientSecret: aksSpPassword.value, }, // Enable RBAC (Role-Based Access Control) for secure interaction between AKS and Azure roleBasedAccessControl: { enabled: true }, }); // Expose the kubeconfig for AKS cluster export const kubeconfig = k8sCluster.kubeConfigRaw; // Create a Kubernetes provider instance that uses our kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: k8sCluster.kubeConfigRaw, }); // Deploy the docker-gc helm chart using the Kubernetes provider const dockerGcChart = new k8s.helm.v3.Chart("docker-gc", { chart: "docker-gc", // You can specify the Helm repository that contains the Docker GC chart. // Assuming "docker-gc" is a chart in the stable repository, or you may need to add repository details. fetchOpts: { repo: "https://kubernetes-charts.storage.googleapis.com/", // Replace with the actual Helm repository URL }, }, { provider: k8sProvider }); // Export the chart name as an output export const chartName = dockerGcChart.metadata.apply(metadata => metadata.name);

    Make sure to replace unique-prefix with a DNS prefix you own or one that's globally unique across Azure.

    This code does the following:

    • Sets up a new Azure Resource Group to organize resources in Azure.
    • Creates an Azure Active Directory (AD) Application and Service Principal, which are used by AKS to interact with other Azure services securely.
    • Creates a new AKS cluster in the specified location with a default node pool of 2 Virtual Machines.
    • Outputs the kubeconfig file that enables you to connect to the Kubernetes cluster using kubectl or other Kubernetes management tools.
    • Initializes the Kubernetes provider with the AKS cluster kubeconfig.
    • Deploys the docker-gc Helm chart to the AKS cluster using Pulumi's Chart resource.

    To use the above code:

    1. Save it to a file called index.ts.
    2. Initialize a new Pulumi project in the same directory as your file.
    3. Install the required Pulumi packages with npm install @pulumi/azure @pulumi/azuread @pulumi/kubernetes @pulumi/pulumi.
    4. Stand up the infrastructure using pulumi up.

    Always check the Helm repository for the most recent information about the docker-gc chart, including its available versions and configurable values that you can set through the values property in the Chart resource.
