1. Deploy the orangehrm helm chart on Azure Kubernetes Service (AKS)


    To deploy the OrangeHRM Helm chart on Azure Kubernetes Service (AKS), we will proceed through the following steps:

    1. Provision an AKS cluster.
    2. Configure kubectl to connect with our provisioned AKS cluster.
    3. Use the Helm chart to deploy OrangeHRM onto the AKS cluster.

    Let's begin by provisioning an AKS cluster. For this, we'll use Pulumi to define the necessary Azure infrastructure. We'll be utilizing the azure-native provider, as it enables us to work directly with Azure resources in a native way.

    For the AKS cluster, we need a resource group and an AKS cluster definition. We'll also set the region to deploy the resources.

    Next, we'll configure our kubectl to connect with AKS using the kubeconfig we get from the AKS cluster resource.

    Once kubectl is set up, we'll deploy the OrangeHRM Helm chart to our AKS cluster. For deploying Helm charts with Pulumi, we will use the kubernetes provider and its helm.sh/v3.Chart resource.

    Below is the complete Pulumi TypeScript program that accomplishes these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure Resource Group const resourceGroup = new azure_native.resources.ResourceGroup("resourceGroup", { resourceGroupName: "myResourceGroup", location: "WestUS", // Choose the appropriate Azure region }); // Create an AKS Cluster const cluster = new azure_native.containerservice.ManagedCluster("cluster", { resourceGroupName: resourceGroup.name, location: resourceGroup.location, agentPoolProfiles: [{ count: 1, maxPods: 110, mode: "System", name: "agentpool", osType: "Linux", vmSize: "Standard_D2_v2", // You can choose a different VM size based on your needs }], dnsPrefix: "aks-orangehrm", }); // Export the Kubeconfig to access the AKS cluster export const kubeconfig = pulumi. all([cluster.name, resourceGroup.name]). apply(([clusterName, resourceGroupName]) => azure_native.containerservice.listManagedClusterUserCredentials({ resourceGroupName: resourceGroupName, resourceName: clusterName, })).apply(creds => { const encoded = creds.kubeconfigs[0].value; if (encoded === undefined) { throw new Error("Kubeconfig not available"); } return Buffer.from(encoded, "base64").toString(); } ); // Define a Kubernetes provider instance that uses our AKS kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Deploy the OrangeHRM Helm Chart onto AKS const orangehrm = new k8s.helm.v3.Chart("orangehrm", { chart: "orangehrm", version: "0.1.0", // Specify the exact chart version you want to deploy fetchOpts: { repo: "https://helm.oci.oracle.com/helm", // The repository URL for Oracle Helm charts }, // Set any values here that you would pass to `helm install --set key=value` values: {}, }, { provider: k8sProvider }); // Export the public IP to access OrangeHRM export const orangehrmEndpoint = orangehrm.getResourceProperty("v1/Service", "orangehrm-orangehrm", "status") .apply(status => status.loadBalancer.ingress[0].ip);

    This program sets up an AKS cluster within the specified resource group. It then fetches the kubeconfig for the AKS cluster which is necessary for kubectl to interact with the cluster. Using this kubeconfig, we then define a Pulumi Kubernetes provider.

    After we've defined our Kubernetes provider, we use it to deploy the OrangeHRM Helm chart to our AKS cluster. Finally, we export the endpoint of the service that gets created as a result of the Helm chart deployment, which can be used to access the OrangeHRM application.

    Remember to replace version in the Chart resource with the appropriate version of the OrangeHRM Helm chart you want to install. Additionally, you may need to set proper values under values if there are specific configurations you want to apply.

    To run this Pulumi program, you would typically run pulumi up after saving your code in a file named index.ts, installing the necessary node dependencies with npm install, and setting up your Pulumi stack with pulumi stack init.
