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 […]
Docker containers are ephemeral by default — all data written inside a container is lost when the container is removed. Docker provides two mechanisms for persisting data and sharing files between containers and the host: volumes (managed by Docker, stored in /var/lib/docker/volumes/) and bind mounts (map a host directory directly into a container). Volumes are […]
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 […]
Deno is a modern JavaScript and TypeScript runtime built on V8 and Rust. Created by Ryan Dahl (the original creator of Node.js), Deno addresses design decisions he regretted in Node.js: Deno has first-class TypeScript support with no build step required, uses ES modules exclusively (no CommonJS), has a secure-by-default permissions model (scripts cannot access the […]
.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 […]
Rust is a systems programming language focused on memory safety, performance, and concurrency. Rust achieves memory safety without a garbage collector through its ownership and borrowing system, which enforces at compile time that there are no dangling pointers, buffer overflows, or data races. This makes Rust suitable for building high-performance systems software where both safety […]
Go (Golang) is a statically typed, compiled systems programming language developed by Google. Its primary design goals are simplicity, fast compilation, and excellent concurrency support through goroutines and channels. Go compiles to a single statically linked binary with no runtime dependencies — deploying a Go application means copying a single binary to the target server. […]
Java is the most widely deployed programming language in enterprise environments, powering banking systems, e-commerce platforms, microservices, Android applications, and big data frameworks like Apache Kafka, Hadoop, and Spark. OpenJDK (Open Java Development Kit) is the open-source reference implementation of the Java SE specification, maintained by Red Hat, IBM, and the Java community. RHEL 9 […]
PM2 is a production-grade process manager for Node.js applications. Running a Node.js app directly with node server.js has a critical limitation: if the process crashes, it stays down until someone manually restarts it. PM2 solves this and much more — it automatically restarts crashed processes, starts applications on system boot, enables zero-downtime reloads for application […]
