Welcome @stoeps.de, the blog of Christoph Stoettner
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.

Last week I didn’t find very useful links to read or articles to share. This week I read more books, so a recommendation for a book this week and two articles with awk
basics.
https://www.packtpub.com/product/the-kubernetes-workshop/9781838820756[The Kubernetes Workshop icon:external-link[], window=_blank]:: Still preparing for CKA, so I read a lot around Kubernetes. This book is brand new and the first chapters are already useful. I think it’s more detailled than the books I read about Kubernetes before.

https://mkaz.blog/working-with-vim/vimwiki/[VimWiki – Working with Vim – mkaz.blog icon:external-link[], window=_blank]:: I switched for daily notes and diary entries to Vimwiki. I like the fast access and combine it with gollum to display in the browser. In the article you find shortcuts and tipps for working with the todo function.

Another week is over, for a quite busy one. I’m still working on automating HCL Connections installation and think about creating pytests for these deployments. So here is the this weeks mix of my bookmarks, tools I used and articles I found interesting.
https://wizardzines.com/comics/bash-errors/[BASH errorhandling - wizard zines icon:external-link[], window=_blank]:: Good intro on Bash errorhandling from Julia Evans

Today I activated Elasticsearch Metrics and Typeahead Search on my demo HCL Connections cluster .
To my surprise the indices weren’t created and I got errors on the wsadmin.sh
commands.
SearchService.createESQuickResultsIndex()
I checked the Elasticsearch pods which showed a running state, but the logs showed following messages:

It is Linkdump time again. I fixed some things during the week, so my https://github.com/Shaarli/Shaarli[Shaarli instance] can use the API now. I do a lot of research and reading on mobile devices (tablet and phone). Now I can share important articles through https://stakali.toneiv.eu/[Stakali] , add short notes and do followups on my other devices (tablet, computer). To automate the linkdump posts, I created a short https://gitlab.com/stoeps/shaarli2hugo[Python script to collect my saved bookmarks] (marked with the tag linkdump) and create an asccidoc document for my hugo instance. So I can do a quick review and post it.

I use Shaarli since ages to collect links, notes and bookmarks. I worked a little bit on that collection and started to share some as public lists .
On my mobile device I bought a license for Stakali , it fits perfectly into my workflows. I often search on my mobile and share the link through Stakali to my desktop. Stakali just needs the URL and the API Key of Shaarli, but I got errors. So I analyzed the source and app with:
