The use of anti-virus and security software is a prerequisite in most infrastructure scenarios. This makes it all the more important to adapt them to the respective usage scenario. The orcharhino as the central hub in the computing cluster is of particular importance.
There are always new hot trends in the IT world: yesterday it was all about AI, ML and Data Science – today everything is running in containers. It’s no wonder the two worlds are coming together: it is now possible to get Tensorflow-based AI environments running in a Kubernetes cluster. Possible, but not necessarily easy, as we learned.
Have you ever googled DevOps and tried to find an answer beyond bullshit bingo? No? Wonderful, then you’ve come to the right place. “Without bullshit” is, after all, exactly the buzzword we use to live DevOps for our customers and also for ourselves. And summarized in one sentence, it means: a mix of the right culture and the right tools.
In December 2020 Red Hat announced a shift in the product politics of CentOS 8. In a nutshell, the Red Hat sponsored CentOS 8 community will focus on CentOS Stream and discontinue CentOS 8 Linux at the end of 2021. This started a broad discussion in the open source operating system community. Which CentOS 8 alternative will you choose?
Container Technology at IT-DLZ
At OSAD 2021, Matthias Kanzog from IT-DLZ Bayern gave an insight into the container technology used.
“In order to be able to deploy applications faster and more flexibly in the future while ensuring data security, the IT DLZ decided to set up its own container operation.” This is Matthias’ answer to the “crucial question” about agility and flexibility in public authorities. Read more
Recently, a participant of a Kubernetes training asked me whether this OpenShift can be set up with orcharhino. He had been an orcharhino user for some time and was familiar with its automation methods, Kubernetes and OpenShift in particular were still relatively new to him. “Yes.”, I replied, but then had to pause, brooding and silent. We’d done this before, but this was OpenShift 3.

Containers have been around much longer than Docker and Kubernetes. But certainly these applications made them more wellknown and also much more accessible. How to build an image for a container and also how it works at runtime has been discussed many times; but what about the state in between? In order to best use and optimize container images in our daily work, we need to understand how they are built. Thus, the following article – garnished with a specially handcrafted image – sheds light on the concept of OCI images.
Starting with version 5.8 orcharhino comes with new provisioning templates for Windows. These extend the variety of functions of your Windows deployments, for example, by installation in networks without DHCP and parameterized domain join.
Docker has started a revolution with its easy access to Linux containers: Containerized applications, microservices, DevOps, GitOps, and Kubernetes are noticeably spreading. But then suddenly it says “Docker support in [kubernetes] is now deprecated and will be removed in a future release”.
Because we made such good experiences in the last two years, also this year a delegation of the ATIX crew travelled to the CfgMgmt Camp (Config Management Camp) in Gent. For ecological reasons we renounced the plane and drove to Belgium with one car.
