UPDATED on 10.6.2019 (after the release of OpenShift 4.1): Added information on OpenShift 4. UPDATED on 30.8.2019: Added information on CodeReady Containers for running single OpenShift node. OpenShift has been often called as “Enterprise Kubernetes” by its vendor – Red Hat. In this article, I’m describing real differences between OpenShift and Kubernetes.
I can’t imagine deployment process of any modern application that wouldn’t be orchestrated by some kind of pipeline. It’s also the reason why I got into containers and Kubernetes/OpenShift in the first place – it enforces changes in your approach toward building and deploying but it makes up for with all these nice features that […]
People are fascinated by containers, Kubernetes and cloud native approach for different reasons. It could be enhanced security, real portability, greater extensibility or more resilience. For me personally, and for organizations delivering software products for their customers, there is one reason that is far more important – it’s the speed they can gain. That leads […]
We waited over 7 months for OpenShift Container Platform 4 release. We even got version 4.1 directly because Red Hat decided not to release version 4.0. And when it was finally released we almost got a new product. It’s a result and implication of acquisition of CoreOS by Red Hat announced at the beginning of […]

Security is a major factor when it comes to a decision of whether to invest your precious time and resources in new technology. It’s no different for containers and Kubernetes. I’ve heard a lot of concerns around it and decided to write about the most important factors that have the biggest impact on the security […]
Beautiful but useless systems Hundreds of applications, thousands of users and millions of requests – that is often a landscape of a modern IT environment. However, problems are still the same.
Imagine for a while that your organization is like a village where there are regular residents and shamans who keep most of the knowledge for themselves. This is a story about them and why it is dangerous, how to manage it and prevent from reaching your goals and causing harm to other residents.
So you’ve decided to go with Kubernetes and started building your container images. Now the question is where to push them and how to manage them properly?
Lepiej nie było nigdy Podobno żyjemy w najbezpieczniejszych czasach – brak wojen od kilkudziesięciu lat, brak poważniejszych epidemii, względny spokój i dobrobyt.
