Deploy the myfirstdockerkuber helm chart on Google Kubernetes Engine (GKE)
TypeScriptTo deploy a Helm chart on Google Kubernetes Engine (GKE) using Pulumi, you'll need to complete a few steps:
-
Set up a GKE cluster: You need a Kubernetes cluster on GKE where you can deploy your Helm chart. This step involves creating a GKE cluster and configuring it appropriately.
-
Deploy the Helm chart: Once your cluster is set up, you'll use Pulumi's Kubernetes provider to deploy a Helm chart to your GKE cluster.
Here's how you can do this with Pulumi in TypeScript. The following program outlines the necessary components required to create a GKE cluster and deploy a Helm chart to that cluster.
Detailed Steps:
-
Initialize your Pulumi project: This is typically done using
pulumi new
and selecting the appropriate template. -
Install the required Pulumi packages: For GKE, you will need the
@pulumi/gcp
package, and for deploying a Helm chart, you will use the@pulumi/kubernetes
package. -
Create a GKE cluster: Define a GKE cluster resource using the
@pulumi/gcp
package. -
Create a Kubernetes provider: Once the GKE cluster is created, use the cluster's credentials to configure a Pulumi Kubernetes provider.
-
Deploy the Helm chart: Use the
@pulumi/kubernetes
package to deploy the Helm chart with the Kubernetes provider configured in the previous step.
Below is the complete Pulumi program for deploying your Helm chart on a GKE cluster:
import * as pulumi from "@pulumi/pulumi"; import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Create a GKE cluster. const cluster = new gcp.container.Cluster("my-cluster", { initialNodeCount: 2, nodeConfig: { machineType: "n1-standard-1", }, }); // Export the Cluster name export const clusterName = cluster.name; // Allocate a static IP for the cluster const clusterIp = new gcp.compute.Address("cluster-ip"); // Export the static IP export const clusterStaticIp = clusterIp.address; // Obtain the Kubeconfig for the newly created GKE cluster. export const kubeconfig = pulumi. all([cluster.name, cluster.endpoint, cluster.masterAuth]). apply(([name, endpoint, masterAuth]) => { const context = `${gcp.config.project}_${gcp.config.zone}_${name}`; return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${masterAuth.clusterCaCertificate} server: https://${endpoint} name: ${context} contexts: - context: cluster: ${context} user: ${context} name: ${context} current-context: ${context} kind: Config preferences: {} users: - name: ${context} user: auth-provider: config: access-token: ${masterAuth.accessToken} cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `; }); // Create a Kubernetes provider instance that uses our cluster from above. const k8sProvider = new k8s.Provider("gkeK8s", { kubeconfig: kubeconfig, }); // Deploy a Helm chart to the GKE cluster. const chart = new k8s.helm.v3.Release("my-helm-chart", { chart: "myfirstdockerkuber", version: "0.1.0", // Replace with the version of your chart // Use namespace: <namespace-name> if you would like to deploy the chart in a specific namespace }, { provider: k8sProvider }); // Export the Helm chart name export const helmChartName = chart.name;
In the provided code:
-
We created a GKE cluster with two nodes using the
gcp.container.Cluster
resource. -
We created a Kubernetes Provider that allows Pulumi to manage Kubernetes resources on the created cluster. The provider uses the kubeconfig from the created GKE cluster.
-
We deployed the
myfirstdockerkuber
Helm chart using thek8s.helm.v3.Release
resource. Please note that you need to replace theversion
field with the version number of yourmyfirstdockerkuber
Helm chart if it's different. -
The
exports
are used to output important information when the Pulumi program is run, including the cluster name, cluster IP, and the Helm chart name.
To run the program:
- Save the code in a file named
index.ts
. - Ensure you've installed Pulumi CLI and configured Google Cloud credentials.
- Execute
pulumi up
to create the resources. This command will also output the cluster name, cluster IP, and the Helm chart name upon successful completion.
Please adjust the
machineType
,initialNodeCount
, and Helm chartversion
based on your specific needs. If your Helm chart needs specific values, you can provide them in thevalues
field of thek8s.helm.v3.Release
args.-
