Deploy the istio-fortio helm chart on Digital Ocean Kubernetes Service
TypeScriptTo deploy an
istio-fortio
Helm chart on Digital Ocean's managed Kubernetes service (DOKS), you'll follow these general steps using Pulumi and TypeScript:-
Set up a Kubernetes cluster on Digital Ocean: Firstly, you'll create a new managed Kubernetes cluster on Digital Ocean using Pulumi's
digitalocean.KubernetesCluster
resource. -
Deploy the Helm chart: Once you have a cluster, you'll use Pulumi's
kubernetes.helm.v3.Chart
resource to deploy theistio-fortio
Helm chart onto your DOKS cluster. Helm charts are a convenient way to package and deploy applications on Kubernetes.
Here's a Pulumi program in TypeScript that will set up the DOKS cluster and deploy the
istio-fortio
Helm chart onto it:import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Create a new DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: digitalocean.Regions.NYC3, version: "1.21.5-do.0", nodePool: { name: "default", size: digitalocean.DropletSlugs.DropletS2VCPU2GB, nodeCount: 2, }, }); // Step 2: Use the Kubernetes provider to connect to the new cluster const provider = new kubernetes.Provider("do-k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }, { dependsOn: cluster }); // Step 3: Deploy the istio-fortio Helm chart on the cluster const chart = new kubernetes.helm.v3.Chart("istio-fortio", { chart: "fortio", // Assuming the chart's name in the Helm repository is "fortio" // Replace `repo` with the URL of the Helm repository where the istio-fortio chart is located repo: "https://furiousgeorge.github.io/helm-charts/", // Make sure to specify the correct repository namespace: "default", // Specify the namespace if it's other than `default` values: { // Specify any custom configuration values here }, }, { provider }); // Export the cluster's kubeconfig and the service endpoint of the Helm chart export const kubeConfig = cluster.kubeConfigs[0].rawConfig; export const serviceEndpoint = chart.getResourceProperty("v1/Service", "default/istio-fortio", "status");
Let's break down what each part of this program does:
-
Cluster Creation: The
digitalocean.KubernetesCluster
resource creates a new Kubernetes cluster in the specified region with the specified version and node pool configuration. You can adjust theregion
,version
, andnodePool
settings to match your requirements. -
Provider Configuration: We instantiate a
kubernetes.Provider
, which uses the kubeconfig of the newly created cluster. This enables Pulumi to deploy resources onto the cluster. ThedependsOn: cluster
argument ensures the provider waits for the cluster to be available before deploying anything. -
Helm Chart Deployment: The
kubernetes.helm.v3.Chart
is used to deploy theistio-fortio
Helm chart onto the DOKS cluster that we just created. You should replace thechart
,repo
, andvalues
fields with the appropriate information for theistio-fortio
chart.
Please note that in the absence of the specific Helm chart for
istio-fortio
, I have used a placeholder for thechart
field and an example repository URL. You should replace these with the actual chart name and repository URL foristio-fortio
.Finally, metadata information is exported:
kubeConfig
provides access to the cluster for use withkubectl
or other tools, whileserviceEndpoint
can potentially provide the network endpoint to access the deployedistio-fortio
service.To run this Pulumi program, place the code in a new Pulumi project directory, and then run
pulumi up
to create the resources. Make sure you have already set up your Digital Ocean access token with Pulumi CLI usingpulumi config set digitalocean:token <YOUR_TOKEN>
.Remember, you'll also need the
@pulumi/digitalocean
and@pulumi/kubernetes
npm packages installed, which you can add withnpm install @pulumi/digitalocean @pulumi/kubernetes
