Kubeapps URL

[tjanitsc]

How can I change the Access Url of the Kubeapps deployment. I want access the Kubeapp from outside the cluster. So the 127.0.0.1 isnt accsessable in my network.

[antgamdia]

You would need to expose the Kubernetes service externally, more info: https://medium.com/google-cloud/kubernetes-nodeport-vs-loadbalancer-vs-ingress-when-should-i-use-what-922f010849e0.

More specifically, regarding Kubeapps, have a look at this FAQ section: https://github.com/kubeapps/kubeapps/blob/main/chart/kubeapps/README.md#how-to-configure-kubeapps-with-ingress

[tjanitsc]

its behind a nginx loadbalancer
But what I have to change in this environment. Which configuration file?

[antgamdia]

I guess you'll need to install Kubeapps with the ingress feature on. It will create an Ingress rule in your cluster, so that you can access it externally. For example, for pointing to example.com you'll need to run:

helm install kubeapps bitnami/kubeapps \
  --namespace kubeapps \
  --set ingress.enabled=true \
  --set ingress.hostname=example.com \
  --set ingress.annotations."kubernetes\.io/ingress\.class"=nginx # or your preferred ingress controller

[tjanitsc]

how long does it take to install kubeapps?

[antgamdia]

From my experience, it shouldn't take more than 1-5 mins

[tjanitsc]

i think it has a problem to pull the data

helm install kubeapps c:\kubeapps --namespace kubeapps --set ingress.enabled=true --set ingr
ess.hostname=cluster2ingress.berlab.de --set ingress.path=/kubeapps --set ingress.annotations."kubernetes.io/ingress.class"=

Kubeapps can be accessed via port 80 on the following DNS name from within your cluster:

kubeapps.kubeapps.svc.cluster.local

To access Kubeapps from outside your K8s cluster, follow the steps below:

1. Get the Kubeapps URL and associate Kubeapps hostname to your cluster external IP:

   export CLUSTER_IP=$(minikube ip) # On Minikube. Use: kubectl cluster-info on others K8s clusters
   echo "Kubeapps URL: http://cluster2ingress.berlab.de/"
   echo "$CLUSTER_IP cluster2ingress.berlab.de" | sudo tee -a /etc/hosts

2. Open a browser and access Kubeapps using the obtained URL.

[tjanitsc]

where can i download a deployable zip?

[antgamdia]

Kubeapps is officially distributed as a Helm chart in the Bitnami Application Catalog, so if want to get a zip, you just need to go to their charts repo and export it as a zip from GitHub, that is: https://github.com/bitnami/charts/archive/refs/heads/master.zip

Then, just go to bitnami/kubeapps and there you'll find the official Kubeapps chart.

[tjanitsc]

ok, but what are the right steps?

1. install the chart
2. update this like: helm dep update C:\kubeapps

[tjanitsc]

I dont find a right process step by step...

[antgamdia]

We don't have any specific guide for installing Kubeapps if, in your environment, Helm is not fully able to retrieve the assets.
The usual getting started should already cover how to install and use Kubeapps.

If you are working in an air-gapped environment, you also may find this another guide useful.
