Kubernetes operator for XP: Install App Fails

Enonic version: 7.11.1
OS: MacOS / Docker-Desktop 4.15.0

I am preparing deployment of XP to a K8-Cluster. I followed the instructions and configurations for a simple deployment here: Kubernetes Operator for Enonic XP

I have Docker-Desktop with Kubernetes Cluster enabled. I could successfully deploy XP (7.11.1) in this K8 cluster.

There is only one warning in the log.

I am working on a NextXP-project and have a simple XP-APP based on Webpack Starter using Next-proxy and a graphQL-controller.

When I try to install this APP in XP using Application App by uploading the jar, I get an error , that the app could not be installed. There are no errors in the log.

I have the same behavior, when I try to install a market-place APP by uploading the jar.

The app runs without issues in a sandbox.

What can I do to debug this?

Did you read this section?

Yes - what exactly do you mean ?

It describes how to upload applications using the Operator. You cannot use the Applications UI for that.

Actually, you can use XP as normal.

This is just a new feature. A flag can be set in XP to disable app upload from Appliations UI.

Sorry, I cannot find this in the docs !

Do you mean in the chart value file here Installation
If so, what is the name of this flag ? If not, where to set this flag.

Sorry, I cannot find this in the docs !

The link I posted above goes to the section describing this. Looks like this:

I understand. But it is described as an optional way to deploy an app.
I guess that it is also possible to install Contentstudio with the Applications-App using the specified url.

So what about the flag @tsi mentioned?
