Install OpenCost on Kubernetes

How to Install OpenCost on Kubernetes with Helm

This guide will walk you through the process of installing OpenCost using Helm, the Kubernetes package manager, ensuring a smooth and efficient setup.

Prerequisites

Before we begin, ensure you have the following tools installed and configured:

• Kubernetes - Installed locally or in a public cloud provider
• kubectl - Configured to communicate with your Kubernetes cluster
• Helm - For managing Kubernetes applications like OpenCost
• Kubernetes Ingress controller - For accessing the installation on a url

Step 1: Add the Helm chart repository

First, add the repository containing the OpenCost helm chart:

helm repo add opencost https://opencost.github.io/opencost-helm-chart
helm repo update
helm search repo opencost

Step 2: Create a namespace (optional)

Isolating applications within Kubernetes namespaces is a good practice. To deploy OpenCost in its own namespace:

kubectl create namespace opencost

Step 3: Install OpenCost using Helm

Now, you'll install OpenCost. The helm chart name is "opencost":

helm install opencost opencost/opencost --namespace opencost --create-namespace

Step 4: Verify the installation

After installation, verify that your OpenCost deployment is running smoothly:

kubectl get pods --namespace opencost
kubectl get all --namespace opencost

Step 5: Customize the OpenCost installation (optional)

This process may require customizing your deployment through a customized values.yaml file, which specifies configuration options.

helm install opencost opencost/opencost --values values.yaml --namespace opencost

Step 6: Access OpenCost

Accessing OpenCost will depend on your chosen service configuration (LoadBalancer, NodePort, or Ingress). For Ingress access, ensure an Ingress controller is operational in your cluster.

Follow the instructions in the helm install notes, the output of Step 3.
