I work at Vegard IT GmbH as a senior consultant with a focus on collaboration software, Kubernetes, security and automation. I mainly deal with HCL Connections, WebSphere Application Server, Kubernetes, Ansible, Terraform and Linux.
Sometimes my daily work results in technical talks and blog articles, which you can follow here more or less regularly. You can find the presentations in the main menu under public speaking .
I created a list of tools I use regularly, most of which have been released under an open source license.
In my spare time I read a lot, test all kinds of technical software and gadgets and try to follow about 200 RSS feeds.
Here you can find a collection of them.
This is my private blog, all opinions are my own.
Additionally to the social accounts, you can reach me on matrix with @stoeps:matrix.org or join my matrix channel #stoeps:matrix.org . For the moment contact me for an invitation to the channel, I need to figure out how many spam accounts will join, if I set it to public.
I save links I want to read later or store because they are interesting in Shaarli .
I try to add some description to each link, so I don’t need to create the linkdump posts.
This is a very old story and it started in school. Stoeps was just my nickname and I have kept it ever since.

I spend the entire day working on a very sizable 4k UHD display, and I frequently ran into the problem of wanting to share my screen with participants in various collaboration tools. Then, viewers claim that my screen is too small on the remote displays due to the display resolution of 3840x2160 pixels.

Elasticsearch in HCL Connections Componentpack is secured with Searchguard and needs certificates to work properly. These certificates are generated by bootstrap during the initial container deployment with
These certificates are valid for 10 years (
chain_ca.pem) or 2 years (
elasticsearch*.pem) and stored in the Kubernetes secrets
elasticsearch-7-secret. So when your HCL Connections deployment is running for 2 years, the certficates stop working.
Last week I played around with the HCL Connections documentation to backup Elasticsearch in the article Backup Elasticsearch Indices in Component Pack .
In the end I found that I couldn’t get the snapshot restored and that I have to run a command outside of my Kubernetes cluster to get a snapshot on a daily basis. That’s not what I want.
During a migration from Cognos Metrics to Elasticsearch Metrics, I had some issues with the index. So I wanted to create a backup of the already migrated data and start over from scratch.
The official documentation has an article on the topic: Backing up and restoring data for Elasticsearch-based components , but I had to slightly adjust the commands to get a successful snapshot.

The last years I had issues with application servers using large amount of CPU and even hanging application servers running the Tiny Spellchecking service. It ended with disabled spellchecking in the Tiny editors
