Deploy the tyk-pump helm chart on Digital Ocean Kubernetes Service
TypeScriptTo deploy the Tyk Pump Helm chart on Digital Ocean Kubernetes Service (DOKS), you should follow these steps:
- Set up a Kubernetes cluster on Digital Ocean using the
digitalocean.KubernetesCluster
resource. - Deploy the Tyk Pump Helm chart to this cluster using the
kubernetes.helm.sh/v3.Chart
resource.
Here's a detailed step-by-step guide on how to accomplish this with Pulumi and TypeScript:
Prerequisites
Before you start, make sure you have the Pulumi CLI and Digital Ocean CLI installed, and that you're logged in to Digital Ocean and have your access token ready.
Step 1: Create a Digital Ocean Kubernetes Cluster
We'll use the
digitalocean.KubernetesCluster
resource to provision a new Kubernetes cluster on Digital Ocean. This resource allows us to specify the region, version, node pool configuration, etc. You can adjust these according to your requirements.Step 2: Deploy Tyk Pump Helm Chart using Pulumi
For deploying Helm charts, we can leverage the
kubernetes.helm.sh/v3.Chart
resource from Pulumi's Kubernetes provider. This resource is a representation of a Helm chart in Pulumi's infrastructure-as-code framework.Now let’s write the code. We start by importing necessary packages, setting up the Kubernetes cluster, and then deploying Tyk Pump Helm chart.
import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as kubernetes from '@pulumi/kubernetes'; // Create a Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc3', version: 'latest', // You might want to specify an explicit version nodePool: { name: 'default', size: 's-2vcpu-2gb', // Choose the size that is appropriate for your workload nodeCount: 2, // Adjust node count according to your needs }, // For more customization, refer to the documentation: // https://www.pulumi.com/registry/packages/digitalocean/api-docs/kubernetescluster/ }); // Once the cluster is provisioned, we configure the Kubernetes provider to use the cluster credentials const k8sProvider = new kubernetes.Provider('do-k8s', { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Now we are ready to deploy the Tyk Pump Helm chart to the cluster const tykPumpChart = new kubernetes.helm.v3.Chart('tyk-pump', { chart: 'tyk-pump', version: '0.1.0', // Specify the version of the chart you want to deploy fetchOpts: { repo: 'https://helm.tyk.io/public/helm/charts/', // Make sure this is the correct repository for Tyk Pump }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and endpoint to access the Kubernetes cluster export const kubeConfig = cluster.kubeConfigs[0].rawConfig; export const clusterEndpoint = cluster.endpoint;
Explanation:
-
Digital Ocean Kubernetes Cluster: The
digitalocean.KubernetesCluster
resource is used to create a Kubernetes cluster on Digital Ocean. You can specify the size, number of nodes, and the Kubernetes version you want to deploy. -
Kubernetes Provider: The
kubernetes.Provider
object configures the Kubernetes provider with the cluster credentials, allowing Pulumi to make changes to the cluster. -
Helm Chart Deployment: Then, we use the
kubernetes.helm.v3.Chart
resource to deploy the Tyk Pump Helm chart. This resource automates Helm operations such as installing and updating charts. InsidefetchOpts
, we specify the Helm repository from which to fetch Tyk Pump. -
Exported Values: Finally, we export the kubeconfig and the cluster endpoint as outputs. This is helpful for accessing or interacting with your Kubernetes cluster from your local machine.
Next Steps
After applying the changes with Pulumi (by running
pulumi up
), your Digital Ocean Kubernetes cluster will be provisioned, and the Tyk Pump Helm chart will be deployed on it. To interact with the cluster, you can use the exported kubeconfig withkubectl
or other Kubernetes tools.- Set up a Kubernetes cluster on Digital Ocean using the
