Deploy the elastic-apm-server helm chart on Digital Ocean Kubernetes Service
TypeScriptTo deploy the Elastic APM Server using the Helm chart on DigitalOcean Kubernetes Service, you will need to follow these steps:
-
Set up a DigitalOcean Kubernetes Cluster: This cluster will be the environment where your Elastic APM Server will run. We'll define a cluster with a node pool of a specified size.
-
Install the Helm Chart for Elastic APM Server: Helm charts are collections of pre-configured Kubernetes resources that can be deployed as a package. The Elastic APM Server Helm chart will contain all the necessary Kubernetes resources needed to run an Elastic APM Server on your DigitalOcean Kubernetes cluster.
We'll be utilizing Pulumi's Kubernetes and DigitalOcean providers to create this setup:
-
digitalocean.KubernetesCluster
: This Pulumi resource represents a Kubernetes cluster on DigitalOcean and allows us to define and configure the cluster. -
kubernetes.helm.sh/v3.Chart
: This Pulumi resource is from the Kubernetes provider to deploy Helm charts on a Kubernetes cluster.
Below is a TypeScript program that demonstrates how to use Pulumi to deploy the Elastic APM Server Helm chart on DigitalOcean Kubernetes Service:
import * as pulumi from '@pulumi/pulumi'; import * as digitalocean from '@pulumi/digitalocean'; import * as k8s from '@pulumi/kubernetes'; // Create a DigitalOcean Kubernetes Cluster const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc1', // Select the appropriate region version: 'latest', // Use the latest available version nodePool: { name: 'default-pool', size: 's-1vcpu-2gb', nodeCount: 2, }, }); // Define the Helm chart for Elastic APM Server const elasticApmChart = new k8s.helm.v3.Chart('elastic-apm-server', { chart: 'elastic-apm-server', version: '7.14.0', // Specify the version of the Elastic APM Server Helm chart fetchOpts: { repo: 'https://helm.elastic.co', // The Helm repository for Elastic APM Server }, }, { provider: new k8s.Provider('k8s-provider', { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Export the cluster kubeconfig and endpoint export const kubeConfig = cluster.kubeConfigs[0].rawConfig; export const clusterEndpoint = cluster.endpoint;
Let's break down what this program does:
- We import the necessary modules from Pulumi's SDK.
- We define a new DigitalOcean Kubernetes cluster called
do-cluster
with a single pool of nodes. - We set up the Elastic APM Server using the Helm chart from the repository provided by Elastic.
- We pass the kubeconfig from the created DigitalOcean cluster to the Kubernetes provider to ensure it can interact with our newly created cluster.
- Finally, we export the kubeconfig and the cluster endpoint so that you can interact with your cluster using
kubectl
or integrate it with your existing infrastructure.
Make sure that you have Pulumi installed, and your environment is configured for DigitalOcean, then you can run
pulumi up
to deploy this program. The Elastic APM Server will then be deployed on your DigitalOcean Kubernetes cluster.-
