The (not so) secret flaws of Kubernetes Secrets When you’re starting learning and using Kubernetes for the first time you discover that there is this special object called Secret that is designed for storing various kinds of confidential data. However, when you find out it is very similar to ConfigMap object and is not encrypted […]
Kubernetes as a standard development platform We started with single, often powerful, machines that hosted many applications. Soon after came virtualization, which didn’t actually change a lot from a development perspective but it did for the field of operations. So developers became mad, and that’s when the public cloud emerged to satisfy their needs instead […]

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.
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 […]

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.
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?
Udostępniam właśnie pierwsze odcinki mojego kursu z Kubernetes. A tutaj opisuję dlaczego to robię.
One of the features that comes with Kubernetes is its ability to scale horizontally services running on it and use available resources more efficiently. I’ve been hearing that containers are just lightweight virtualization (which is not true) so you can put more apps on the same resources. I can agree that it’s partially true
