Deploy the sentry-kubernetes helm chart on Azure Kubernetes Service (AKS)
TypeScriptTo deploy the Sentry Kubernetes Helm chart on an Azure Kubernetes Service (AKS) cluster using Pulumi, you will need to perform several steps. These include setting up an AKS cluster, installing and configuring Helm on your local machine, and finally, deploying the Sentry Helm chart to the cluster.
Here's an outline of the steps we're going to program:
- Create an AKS cluster using the
azure-native
Pulumi provider, which interacts with Azure resources using the native Azure Resource Manager API. - Once the AKS cluster is up and running, we will obtain the Kubernetes configuration needed to communicate with the AKS cluster.
- Use the
kubernetes
Pulumi provider to deploy the Sentry Kubernetes chart using Helm.
Let's go through the programming aspect of these steps.
Step 1: Create an AKS Cluster
First, we will define an AKS cluster resource using the
azure-native.containerservice.KubernetesCluster
class. Here we specify the parameters for creating the cluster, such as the number of nodes, the size of nodes, and the location.import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Define the AKS cluster const aksCluster = new azure.containerservice.KubernetesCluster("aksCluster", { resourceGroupName: resourceGroup.name, location: resourceGroup.location, agentPoolProfiles: [{ count: 3, // Number of nodes in the node pool vmSize: "Standard_DS2_v2", // Size of the VMs in the node pool mode: "System", // Mode of the agent pool name: "agentpool" // Name of the agent pool }], dnsPrefix: "sentryk8s", // DNS prefix for the AKS cluster linuxProfile: { adminUsername: "adminuser", // Username for the admin user on the Linux VMs ssh: { publicKeys: [{ keyData: /* Your SSH public key */ }] // SSH public key for secure access }, }, identity: { type: "SystemAssigned" // System-assigned identity for the AKS cluster }, }); // Output the kubeconfig to access the AKS cluster export const kubeconfig = aksCluster.kubeConfig;
Step 2: Configure Kubernetes Provider
Next, we will set up the Kubernetes provider to communicate with your newly created AKS cluster using the
kubeconfig
obtained from the AKS cluster.// Create a Kubernetes provider instance using the kubeconfig from the AKS cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: aksCluster.kubeConfig, });
Step 3: Deploy the Sentry Kubernetes Helm Chart
Finally, we deploy the Sentry Helm chart. We utilize the
k8s.helm.v3.Chart
class to manage the installation of Helm charts. You can specify the Sentry Helm chart parameters in thevalues
property.// Deploy the Sentry Helm chart to the AKS cluster const sentryChart = new k8s.helm.v3.Chart("sentryChart", { chart: "sentry-kubernetes", version: "xxx", // Specify the version of the Sentry Helm chart you wish to use fetchOpts: { repo: "https://sentry-kubernetes.github.io/charts", // Sentry Kubernetes Helm chart repo }, }, { provider: k8sProvider });
Here's the complete program:
import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create a resource group const resourceGroup = new azure.resources.ResourceGroup("myResourceGroup"); // Define the AKS cluster const aksCluster = new azure.containerservice.KubernetesCluster("aksCluster", { resourceGroupName: resourceGroup.name, location: resourceGroup.location, agentPoolProfiles: [{ count: 3, vmSize: "Standard_DS2_v2", mode: "System", name: "agentpool" }], dnsPrefix: "sentryk8s", linuxProfile: { adminUsername: "adminuser", ssh: { publicKeys: [{ keyData: /* Your SSH public key */ }] }, }, identity: { type: "SystemAssigned" }, }); // Configure Kubernetes provider to use the output kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: aksCluster.kubeConfig, }); // Deploy the Sentry Helm chart using the Kubernetes provider const sentryChart = new k8s.helm.v3.Chart("sentryChart", { chart: "sentry-kubernetes", version: "x.y.z", // Specify the version you want to use fetchOpts: { repo: "https://sentry-kubernetes.github.io/charts", }, }, { provider: k8sProvider }); // Export the Kubernetes cluster name and kubeconfig export const clusterName = aksCluster.name; export const kubeconfig = aksCluster.kubeConfig;
To run this program, you'll need to replace the
/* Your SSH public key */
placeholder with your actual SSH public key. Then you can use Pulumi's CLI tools to deploy this program.This program will create the AKS cluster and deploy Sentry. Note that actual Helm chart parameters will depend on the Sentry version and configuration options you choose. You'll need to replace
x.y.z
with the actual version of the Sentry Helm chart you wish to install.More about the resources being used:
-
azure.containerservice.KubernetesCluster
: This class is used to define an AKS cluster in your Azure subscription. -
k8s.helm.v3.Chart
: This class is used to deploy Helm charts into a Kubernetes cluster. You use this to deploy Sentry to AKS, which has Helm as one of its package management tools. -
k8s.Provider
: This class is used to configure the Kubernetes provider, which in turn is used to interact with our AKS cluster. We configure it with the kubeconfig obtained from the AKS cluster, which contains credentials for the cluster.
Remember to handle sensitive data such as the SSH keys and kubeconfig in a secure manner and consider using Pulumi's secret management to encrypt such data.
