stoeps.de - Christoph Stoettner's Blog
I work at Vegard IT GmbH as a senior consultant, focusing on collaboration software, Kubernetes, security, and automation. I primarily work with HCL Connections, WebSphere Application Server, Kubernetes, Ansible, Terraform, and Linux.
My daily work occasionally leads to technical talks and blog articles, which I share here more or less regularly. You can find my presentations in the main menu under Public Speaking .
I’ve compiled a list of tools I use regularly, most of which have been released under open source licenses.
In my spare time, I read extensively, test various technical software and gadgets, and try to keep up with about 200 RSS feeds. Here you can find a curated collection of them.
This is my private blog, all opinions are my own.

I’m still working on encrypting all network traffic between Connections and Component Pack servers. This time I checked the Ingress-Nginx Controller - TLS/HTTPS documentation.
The default configuration for connecting IHS with Component Pack uses the plain HTTP port 32080. All traffic like /social or the Tailored Experience wizard is routed from IHS to Kubernetes on port 32080.
Our target is to encrypt the traffic on port 32443.

At the moment I’m working with a customer to secure all traffic in HCL Connections. The target is to have only encrypted network traffic between servers.
Today I started enabling encryption to Redis. This is a documented process , but the documentation is outdated and incomplete.
Today I read the article KB0118248 and remembered my blog post from 2018 . I also checked the attached aha idea where a comment states that you can use iframe for Youtube. Despite what KB0118248 incorrectly states, it is absolutely possible to embed videos in HCL Connections blogs and wikis using the HTML video tag as demonstrated in this post.

The HCL Connections documentation describes the process for configuring Windows desktop single-sign-on in a somewhat complicated way. Here are the necessary steps for setting up with the highest possible encryption.

I received several complaints from users who struggle to identify uploaded images in the File Uploads section of blogs. This happens because pasted images get cryptic filenames like editor_image_ + UUID, making it challenging to identify and delete unused images.

I use chezmoi
for my dotfiles. To find out why and how to get started, check out my talk
from Chemnitzer Linuxtage 2025
.
Within chezmoi, you can use the file .chezmoiexternal.toml to download archives or git repositories during updates. This is particularly useful for managing external dependencies. Let me walk you through some common use cases.
