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.

The last months I built a lot of environments for tests with IBM Connections Componentpack, Rancher, plain Kubernetes, IBM Domino and some more. In former years, I deployed single virtual machines, cloned them and created snapshots to “easily” jump back in cases of errors. Then I found Packer , which helped me to automate the first virtual machines on my local notebook.
Now I use Packer to create templates for VMware vSphere, which then are deployed and multiplied with Terraform . Terraform needs some packages installed in the template, that it can provision virtual machines on vSphere.

Since thursday the gpn19 (Gulasch Programmiernacht) is taking place in Karlsruhe at ZKM. I’m happy that I got the chance to give two talks:

The last IBM Connections 6.0 CR4 introduced the new feature “Sharing Files via Link”. A quite handy way to share files with users by link. Just open the file, go to sharing and select “Share by Link”.
“Share by Link” makes it easy to share and grant read access to personal and Community files.

A lot of people don’t like to store credentials in mobile apps or browsers. A good workaround is the usage of OAuth 2.0 tokens, but the application needs to support it and the server you’re talking to too. The IBM Connections Mobile App can use it for authentication.
OAauth2 can be used directly with WebSphere Application Server and Connections 6.0. There are no special OAuth servers or applications needed!
The Documentation at IBM was a little bit confusing for me, there are lots of sidenotes, but you just need to do following steps, to use OAuth 2.0 token-based authentication with the IBM Connections Mobile App.

In the last days I had a problem with a crashed virtual disk on a WebSphere Application Server. The backup team was able to recover all the data, but the operating system needs to be reinstalled. The operating system was Red Hat Linux, so rpm-based. One of the first tasks after recovery was to identify and reinstall missing packages.
