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.

Create your first installation with Ansible

In the post Create A Test Environment with Terraform and KVM I created the first three virtual machines, now we configure a DNS server so name resolution works as expected.

Since HCL Connections started to add Kubernetes to the stack, we need to use proper name resolution instead of just editing /etc/hosts. That’s a bit of an effort, but in the end it is way easier than checking several hosts if the hosts file is uptodate.

Create A Test Environment With Terraform And KVM

I create a lot of virtual machines during the week to test deployments, or try to digg into problems of deployments. In the past I used Vmware Workstation, Oracle VirtualBox or MS HyperV on my desktops, but I also used Vmware ESX. I tried to use Vagrant and Packer to prepare images and distribute them, but wasn’t satisfied at all.

The newsletter in version 2 format has one big disadvantage, we or our users lost the easy links to the topic, author profile or application.

Repair Administration Panel of Connections 7 for Chromium-based Browsers

Connections 7 has a new Administration Console to access Communities Template administration and Mobile Administration. The Administration Console can be reached on https://cnx-hostname/cnxadmin/. The / at the end is important, because the ingress rule just forwards /cnxadmin/(.*). On Firefox you get this view: /cnxadmin/ panel With Chrome (Chromium, Edge) the left menu is missing. There is a display: inline-flex for some elements in index.css of the Administration Console. So how can we inject a repaired css file into the container? ConfigMap One quick and dirty way is to use a configMap with the adjusted stylesheet. So I did the following:

Upload Files via IBM HTTPServer (mod_ibm_upload) to HCL Connections

The last days I analyzed an issue, that file uploads to HCL Connections via IBM HTTPServer stopped working on a fresh installed 6.5CR1.

Today I configured a Connections 7 and tried with it. I think that the official documentation is old in some important parts for the upload configuration.

First of all my IBM HTTPServer 8.5.5.18 is not 32-bit like the documentation tells us:
