Deploy the snyk-exporter helm chart on Linode Kubernetes Engine
TypeScriptTo deploy the
snyk-exporter
Helm chart on Linode Kubernetes Engine (LKE) using Pulumi, we will need to follow these steps:- Set up a new Pulumi project: If you haven't already, you'll need to create a new Pulumi project for your Kubernetes infrastructure.
- Configure Pulumi for Linode: You have to set up the appropriate cloud provider configuration for Pulumi to interact with Linode.
- Provision a Kubernetes Cluster on LKE: Deploy a Kubernetes cluster on Linode Kubernetes Engine.
- Deploy the Helm Chart: Install the
snyk-exporter
Helm chart on the provisioned Kubernetes cluster.
For these steps, we will be using the Pulumi Kubernetes provider to interact with Kubernetes and perform operations like creating a cluster and deploying Helm charts.
Now let's proceed with the deployment. Below is a complete Pulumi program in TypeScript, which will create a new Linode Kubernetes cluster and deploy the
snyk-exporter
Helm chart. Please ensure that you have installed Pulumi CLI and set up your Linode API token according to the Pulumi Linode provider documentation.import * as linode from "@pulumi/linode"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Provision a new Linode Kubernetes Engine cluster const cluster = new linode.LkeCluster("my-cluster", { label: "my-cluster", k8sVersion: "1.20", region: "us-central", pools: [{ type: "g6-standard-2", count: 3, // Number of nodes in the node pool }], }); // Step 2: Configure the Kubernetes provider to use the kubeconfig from the Linode cluster const kubeconfig = cluster.kubeconfig.apply(JSON.stringify); const k8sProvider = new kubernetes.Provider("k8s-provider", { kubeconfig, }); // Step 3: Deploy the snyk-exporter helm chart const chart = new kubernetes.helm.v3.Chart("snyk-exporter", { chart: "snyk-exporter", // The name of the helm chart version: "1.0.0", // Specify the version of the chart you want to deploy // Add the repository where the chart is located if it's not in the default helm repo repositoryOpts: { repo: "https://charts.helm.sh/stable", }, // If you have specific values you want to override in the chart, specify them here values: { service: { type: "LoadBalancer", }, }, }, { provider: k8sProvider }); // Export the endpoint of the snyk-exporter service export const snykExporterServiceEndpoint = chart.getResourceProperty("v1/Service", "snyk-exporter-snyk-exporter", "status").apply(status => status.loadBalancer.ingress[0].ip);
Here's a rundown of what each section of the code is doing:
- We import the necessary
linode
andkubernetes
modules from Pulumi's package collection. - We set up the LKE cluster with the desired Kubernetes version, region, and size and number of nodes.
- We retrieve the
kubeconfig
file for the newly created cluster, which is needed to communicate with the cluster. - We create a new
Provider
resource, which represents the interface to the Kubernetes cluster. - With the Helm Chart resource
kubernetes.helm.v3.Chart
, we install thesnyk-exporter
chart, passing in any overridden values you'd like to specify. - Finally, we export the IP address of the
snyk-exporter
service, which can be used to access the deployed application.
To execute this program:
- Save the code in a file named
index.ts
. - Run
pulumi up
from the command line in the same directory as yourindex.ts
file. This will start the Pulumi deployment process. - Follow the prompts from Pulumi to preview and confirm the deployment.
Please remember to replace the
chart
,version
, andrepo
fields with the actual values corresponding to thesnyk-exporter
chart if they are different from the placeholders provided.Once the deployment is successful, Pulumi will output the service endpoint which you can use to interact with the
snyk-exporter
deployment.
