Deploy the codecov helm chart on Linode Kubernetes Engine
TypeScriptDeploying a Helm chart to a Kubernetes cluster managed by Linode involves several steps. Before deploying the Helm chart, you must have a functioning Linode Kubernetes Engine (LKE) cluster. Once you have your cluster, the steps are as follows:
- Set up a Pulumi project: Install Pulumi and create a new project.
- Install required packages: For working with Kubernetes and Helm in Pulumi, you will need the
@pulumi/kubernetes
package. - Access the Kubernetes Cluster: You will need to obtain the kubeconfig file for your LKE cluster, which allows Pulumi to interact with it.
- Deploy the Helm chart: Define the Helm chart from the
codecov
repository you wish to deploy to your cluster.
Here is a TypeScript program that showcases how you would deploy the
codecov
Helm chart on an LKE cluster using Pulumi:import * as k8s from "@pulumi/kubernetes"; // Create a provider resource to specify the kubeconfig. const provider = new k8s.Provider("lke-provider", { kubeconfig: "<KUBECONFIG_CONTENT>", // You need to replace <KUBECONFIG_CONTENT> with your actual kubeconfig content }); // Deploy the codecov Helm chart using the kubernetes.helm.v3.Chart class. const codecovChart = new k8s.helm.v3.Chart("codecov", { chart: "codecov", version: "<CHART_VERSION>", // Specify the version of the Codecove Helm Chart you wish to deploy fetchOpts: { repo: "https://charts.codecov.io", // Provide the correct repository URL for the codecov chart } }, { provider }); // Export the URL of the deployed service. export const url = codecovChart.getResourceProperty("v1/Service", "codecov", "status").apply(status => status.loadBalancer.ingress[0].ip);
In this program, we first import the
@pulumi/kubernetes
package to work with Kubernetes resources. Then we create a Kubernetes provider pointing to our Linode cluster by supplying the kubeconfig content you get from Linode.The
codecov
Helm chart is deployed using a Pulumi Kubernetes Helm Chart resource. In thechart
field, we specify the name of the Helm chart, which iscodecov
in this case. Theversion
field is where you specify the version number of the chart you wish to deploy. We also specify the Helm chart's repository URL usingfetchOpts.repo
.Finally, we export the URL where the
codecov
service can be accessed. This assumes that thecodecov
Helm chart creates a Kubernetes Service of typeLoadBalancer
which exposes an IP address to access the service.You will need to obtain your LKE kubeconfig and place its content in the program. Also, ensure you have the correct values for the
chart
andversion
fields. The version should correspond to a valid chart version forcodecov
.Save this program in a
index.ts
file within your Pulumi project directory.To run the deployment:
- Open a terminal and navigate to your Pulumi project directory.
- Run
pulumi up
. - Pulumi will display a preview of the resources that will be created. If everything looks correct, select
yes
to proceed with the deployment.
After the deployment is complete, the LoadBalancer IP address for your
codecov
service will be displayed as an output, which you can use to access yourcodecov
instance.
