Deploy the stakater-notify-slack helm chart on Google Kubernetes Engine (GKE)
TypeScriptTo deploy the
stakater-notify-slack
Helm chart on Google Kubernetes Engine (GKE), you'll need to complete several steps:-
Set up a GKE cluster: You need to have a running GKE cluster. If you already have one, you can skip this step. If not, I'll show you how to create one using Pulumi.
-
Install Pulumi's GKE package: This package allows us to interact with GKE.
-
Install Pulumi's Kubernetes package: This package is used to interact with Kubernetes resources, including deploying Helm charts.
-
Deploy the Helm chart: Finally, we'll deploy the
stakater-notify-slack
Helm chart to your GKE cluster.
Now, let's walk through the code required to accomplish this.
Step 1: Creating a GKE cluster
Below, you'll find the code to create a GKE cluster. This assumes you've already set up your GCP project and have configured Pulumi to use your GCP credentials.
import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Create a GKE cluster const cluster = new gcp.container.Cluster("my-gke-cluster", { initialNodeCount: 1, minMasterVersion: "latest", nodeVersion: "latest", nodeConfig: { machineType: "n1-standard-1", oauthScopes: [ "https://www.googleapis.com/auth/compute", "https://www.googleapis.com/auth/devstorage.read_only", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/monitoring" ], }, }); // Export the Cluster name export const clusterName = cluster.name; // Export the Kubeconfig export const kubeconfig = cluster.endpoint.apply(endpoint => `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${cluster.masterAuth.clusterCaCertificate} server: https://${endpoint} name: gke_cluster contexts: - context: cluster: gke_cluster user: gke_cluster name: gke_cluster current-context: gke_cluster kind: Config preferences: {} users: - name: gke_cluster user: auth-provider: config: cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `);
Step 2: Setting up Pulumi Kubernetes Provider
Once you have your GKE cluster, you need to configure Pulumi's Kubernetes provider to use the generated
kubeconfig
.// Create a Kubernetes provider instance that uses our cluster from step 1. const k8sProvider = new k8s.Provider("gkeK8s", { kubeconfig: kubeconfig, });
Step 3: Deploying the Helm Chart
Now it's time to deploy the
stakater-notify-slack
Helm chart. You'll need to add the Helm repository that contains the chart or specify the chart location if you have it locally.// Create a Helm Release for the stakater-notify-slack chart. const helmChart = new k8s.helm.sh.v3.Release("notify-slack", { chart: "stakater-notify-slack", version: "x.x.x", // specify the chart version repositoryOpts: { repo: "https://stakater.github.io/stakater-charts", // Helm chart repository }, values: { // Specify your configuration for notify-slack slack: { webhookurl: "https://hooks.slack.com/services/your/webhook/url", // Other Slack-related configurations... }, // Any other configurations for notify-slack... }, }, { provider: k8sProvider }); // Export the release name export const helmReleaseName = helmChart.name;
In the
values
block, replace the actual values based on yourstakater-notify-slack
Helm chart configuration, such as the Slack webhook URL.Complete Program
Now let's put all the pieces together into one Pulumi program:
import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a GKE cluster const cluster = new gcp.container.Cluster("my-gke-cluster", { initialNodeCount: 1, minMasterVersion: "latest", nodeVersion: "latest", nodeConfig: { machineType: "n1-standard-1", oauthScopes: [ "https://www.googleapis.com/auth/compute", "https://www.googleapis.com/auth/devstorage.read_only", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/monitoring" ], }, }); export const clusterName = cluster.name; export const kubeconfig = cluster.endpoint.apply(endpoint => `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${cluster.masterAuth.clusterCaCertificate} server: https://${endpoint} name: gke_cluster contexts: - context: cluster: gke_cluster user: gke_cluster name: gke_cluster current-context: gke_cluster kind: Config preferences: {} users: - name: gke_cluster user: auth-provider: config: cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `); // Step 2: Create a Kubernetes provider const k8sProvider = new k8s.Provider("gkeK8s", { kubeconfig: kubeconfig, }); // Step 3: Deploy the Helm chart const helmChart = new k8s.helm.sh.v3.Release("notify-slack", { chart: "stakater-notify-slack", version: "x.x.x", // specify the chart version repositoryOpts: { repo: "https://stakater.github.io/stakater-charts", // Helm chart repository }, values: { slack: { webhookurl: "https://hooks.slack.com/services/your/webhook/url", }, // Any other configurations for notify-slack... }, }, { provider: k8sProvider }); export const helmReleaseName = helmChart.name;
Make sure to replace the placeholder values like
"x.x.x"
for the chart version andyour/webhook/url
with the Slack webhook URL that you have. The same goes for any other configurations you might need for thestakater-notify-slack
Helm chart.This code will create a new GKE cluster, set up the Kubernetes provider, and deploy the Helm chart, all using Pulumi's TypeScript programming model.
