+title = "Installing openQA on Kubernetes with Helm Charts"
+date = 2025-06-04
+
+[taxonomies]
+categories = ["Linux"]
+
+[extra]
+author = "Emil Miler"
++++
+
+Recently, I experimented with Kubernetes by installing [openQA](https://open.qa/) using Helm Charts. This article is a simple guide on how to do the same locally on your computer, with minimal effort.
+
+<!-- more -->
+
+You need a working cluster. There are several single-node management tools that let you run a Kubernetes cluster locally on your machine, such as [k3d](https://k3d.io/), [kind](https://kind.sigs.k8s.io/), or [minikube](https://minikube.sigs.k8s.io/). They provide a cluster entirely isolated within a container.
+
+I will be using minikube.
+
+
+## Installation of Tools
+
+Install minikube -- or any other management tool -- along with *helm*. For example, on Void Linux:
+
+```
+xbps-install -S minikube kubernetes-helm
+```
+
+You also have to have a running container engine, such as [Podman](https://podman.io/) or [Docker](https://www.docker.com/). Configuring a container engine is outside the scope of this article.
+
+
+## Preparing the Cluster
+
+
+
+Since I am using minikube, I can simply start it like so:
+
+
+```
+minikube start
+```
+
+This might take a while during the initial setup. If you want, you can also run a web-based dashboard for better visualization and debugging.
+
+```
+minikube dashboard
+```
+
+The dashboard will open in your default browser.
+
+
+## Downloading openQA Charts
+
+The official charts are available in the [openQA source code repository](https://github.com/os-autoinst/openQA), which can be cloned with the following command:
+
+
+```
+git clone https://github.com/os-autoinst/openQA.git
+```
+
+If you have GitHub setup properly with SSH, you might use this instead:
+
+```
+git clone git@github.com:os-autoinst/openQA.git
+```
+
+The charts themselves are stored in `container/helm`. You can change your working directory to that location:
+
+```
+cd openQA/container/helm
+```
+
+### Chart Structure
+
+The `charts` folder contains several different charts:
+
+- `openqa` -- Parent chart.
+- `webui` -- Web interface and API for openQA.
+- `worker` -- openQA worker that performs the actual test execution.
+
+We will be working with the parent chart `openqa`. Since it references the other charts, they will be handled automatically by the parent.
+
+
+## Installing openQA
+
+We then have to update dependencies and install openQA:
+
+```
+$ helm dependency update charts/openqa/
+$ helm install openqa charts/openqa/
+```
+
+We can also list installed releases to confirm that openQA was deployed:
+
+```
+$ helm list
+NAME  	NAMESPACE	REVISION	UPDATED                                 	STATUS  	CHART       	APP VERSION
+openqa	default  	1       	2025-06-19 12:39:08.150021755 +0200 CEST	deployed	openqa-0.1.0
+```
+
+The minikube dashboard also lists all running pods:
+
+![Minikube Dashboard, Pods](minikube-dashboard-pods.png)
+
+
+### Accessing openQA WebUI
+
+Since openQA is confined to its own network within minikube, it is not directly accessible from the host system. Below are the services running inside minikube:
+
+```
+$ kubectl get services
+NAME           TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)                               AGE
+db             ClusterIP   10.103.192.20   <none>        5432/TCP                              6m34s
+db-hl          ClusterIP   None            <none>        5432/TCP                              6m34s
+kubernetes     ClusterIP   10.96.0.1       <none>        443/TCP                               174m
+openqa-webui   ClusterIP   10.104.24.71    <none>        9526/TCP,9527/TCP,9528/TCP,9529/TCP   6m34s
+```
+
+First, we need to create a proxy within the minikube network:
+
+```
+minikube tunnel
+```
+
+The openQA WebUI is running at `10.104.24.71` on port `9526` and is now accessible directly from the browser.
