Kubernetes is the industry-standard container orchestration platform for automating deployment, scaling, and management of containerised applications across clusters of servers. While Kubernetes is typically set up using managed services (EKS, GKE, AKS) in cloud environments, installing it with kubeadm on bare-metal or on-premises servers provides full control over the cluster configuration. kubeadm is the official […]
Podman Compose (podman-compose) is a Python implementation of the Docker Compose specification that uses Podman instead of Docker. It allows running existing docker-compose.yml / compose.yaml files with Podman’s rootless, daemon-less container engine. For teams migrating from Docker to Podman, podman-compose provides a familiar workflow with minimal configuration changes. Alternatively, Podman 4.0+ includes a native podman […]
Podman is Red Hat’s recommended Docker-compatible container engine that runs containers without requiring a root-owned daemon. Unlike Docker, which requires the Docker daemon (dockerd) running as root, Podman runs containers directly as the user executing the command — a model called rootless containers. This eliminates an entire class of privilege escalation vulnerabilities: even if a […]
Portainer is a lightweight, web-based Docker management UI that makes container management accessible without needing the Docker CLI. It provides a graphical interface for managing containers, images, volumes, networks, Docker Compose stacks, and container registries. Portainer Community Edition (CE) is open-source and supports Docker standalone, Docker Swarm, and Kubernetes environments. It is particularly valuable for […]
A private Docker registry allows organisations to store and distribute container images internally, without relying on Docker Hub or a cloud registry. This is essential for teams working with proprietary application images that cannot be stored in public registries, organisations with strict data sovereignty requirements, and environments with limited internet access. Docker provides an official […]
Efficient Docker image and container management is fundamental to maintaining a healthy container environment. Docker images accumulate on hosts — old base images, build cache layers, and unused intermediate images can consume tens of gigabytes of disk space if not managed regularly. Understanding the Docker image layer model is key: images consist of read-only layers […]
Docker Compose is a tool for defining and running multi-container Docker applications from a single YAML configuration file (docker-compose.yml or compose.yaml). Instead of manually running multiple docker run commands and configuring networks and volumes by hand, Docker Compose allows you to declare all services (web application, database, cache, message queue) in one file and start […]
Docker Engine is the industry-standard container platform that packages applications and their dependencies into portable, isolated containers. A Docker container bundles the application code, runtime, libraries, and configuration into a single image that runs identically on any Linux host with Docker installed, eliminating the “it works on my machine” problem. RHEL 9 does not include […]
.NET is Microsoft’s open-source, cross-platform application framework that runs on Linux, macOS, and Windows. .NET 8 (the current LTS release) includes the ASP.NET Core web framework for building REST APIs and web applications, Entity Framework Core ORM, and a high-performance Kestrel HTTP server. .NET applications are compiled to platform-independent intermediate language (IL) bytecode and run […]
Ruby is a dynamic, object-oriented programming language best known as the language behind Ruby on Rails, the influential web framework that popularised convention-over-configuration and RESTful web applications. rbenv is the standard Ruby version manager for production servers — it allows installing and switching between multiple Ruby versions per user or per directory, without requiring root […]
