The Rise of the Open-Source Alternative: OpenSearch for the Modern SRE In the dynamic world of cloud-native infrastructure, robust observability is not just a nice-to-have; it's a foundational requirement for any Site Reliability Engineer (SRE). For years, Elasticsearch domina
When building applications in Kubernetes, one of the most important challenges is efficiently managing workloads. You want your services to scale up when demand spikes, and scale down (even to zero) when idle, to save resources and reduce costs. This is especially critical in pro
Introduction As organizations increasingly rely on containerized applications, ensuring their performance, stability, and reliability becomes a critical task. Docker makes it easy to package and deploy applications, but without proper monitoring, you may miss vital insights in
Running a container doesn’t mean your app is running fine. It might look like everything’s green from the outside... but inside? Your app could be frozen, stuck, or completely dead 🧊💀 Welcome to the world of Docker HEALTHCHECK — a super underrated feature that can make or br
Monitoring Docker containers is crucial—not just in production, but right from the development phase. Early monitoring helps catch performance issues, resource bottlenecks, and unexpected behaviors before they escalate. While tools like Grafana and Prometheus are powerful, they m
Welcome to the first post in our Helm series! Whether you’re a DevOps engineer, cloud enthusiast, or just getting started with Kubernetes, you’re about to discover a powerful tool that can make your life way easier: Helm. In this post, we’ll dive into: What is Helm? Wha
Nowadays we have powerfull machines which can compile large and heavy files in record time. However is not always the case when we have resources enough and we need to dedicate just a few for compiling our Docker images. That's why in this post we are gonna cover a few topics to
Nowadays many of us work in daily basis with Docker, and we create our own Docker images with Dockerfile. However, do you know how to make Docker images more secure? When we are writing our Dockerfile, Docker is using by default the root user to run the commands declared t
