Install Open WebUI on Kubernetes

How to Install Open WebUI on Kubernetes with Helm

This guide will walk you through the process of installing Open WebUI 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 Open WebUI
• Kubernetes Ingress controller - For accessing the installation on a url

Step 1: Add the Helm chart repository

First, add the repository containing the Open WebUI helm chart:

helm repo add open-webui https://open-webui.github.io/helm-charts
helm repo update
helm search repo open-webui

Step 2: Create a namespace (optional)

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

kubectl create namespace open-webui

Step 3: Install Open WebUI using Helm

Now, you'll install Open WebUI. The helm chart name is "open-webui":

helm install open-webui open-webui/open-webui --namespace open-webui --create-namespace

Step 4: Verify the installation

After installation, verify that your Open WebUI deployment is running smoothly:

kubectl get pods --namespace open-webui
kubectl get all --namespace open-webui

Step 5: Customize the Open WebUI installation (optional)

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

helm install open-webui open-webui/open-webui --values values.yaml --namespace open-webui

Step 6: Access Open WebUI

Accessing Open WebUI 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.
