Beyond docker-in-docker: PikoCI's approach to ephemeral test services
Posted on June 14, 2026, Level beginner Resource Length medium
This article critiques common CI/CD integration testing patterns, such as Docker-in-Docker and shared databases, highlighting their fragility and maintenance overhead. It introduces PikoCI's alternative approach, treating services as first-class, ephemeral entities that run alongside job tasks, ensuring isolated, reliable, and clean test environments without the security risks of privileged containers.

Docker's best-kept secret: How observability saves developers' sanity
Posted on July 6, 2025, Level beginner Resource Length medium
Observability is crucial for managing the increasing complexity of modern distributed software systems, especially those built with Docker containers and microservices. Traditional monitoring often falls short, leading to slow troubleshooting and increased Mean Time To Resolution (MTTR). End-to-end observability, particularly through distributed tracing, provides deep insights into system behavior, enabling proactive detection of performance issues and improved reliability.

How to run GUI-based applications in Docker
Posted on July 4, 2025, Level beginner Resource Length medium
Docker is commonly used for server-side and command-line apps. However, with the right setup, you can also run GUI-based applications inside containers. These containers can include GUI libraries and display tools, which enable apps to run in a secure and isolated environment. Docker containers can run GUI applications by configuring display sharing with the host system. This approach packages applications with their dependencies while maintaining isolation, enabling consistent cross-platform deployment without cluttering the host system. By Anees Asghar.

Wasm vs. Docker: Performant, secure, and versatile containers
Posted on August 18, 2024, Level intermediate Resource Length medium
Docker and WebAssembly (Wasm) represent two pivotal technologies that have reshaped the software development landscape. You've probably started to hear more about Wasm in the past few years as it has gained in popularity, and perhaps you've also heard about the benefits of using it in your application stack. This may have led you to think about the differences between Wasm and Docker, especially because the technologies work together so closely. By Savannah Ostrowski, and Sohan Maheshwar.

Understanding networking in Kubernetes
Posted on November 3, 2023, Level intermediate Resource Length medium
Kubernetes relies on Container Network Interface (CNI) plugins to assign IP addresses to pods and manage routes between all pods. Kubernetes doesn't ship with a default CNI plugin, however, managed Kubernetes offerings come with a pre-configured CNI. By Peter Jausovec.

How container networking works at Platform.sh
Posted on November 2, 2023, Level intermediate Resource Length medium
We'll take a look at how we wire (most of) it up. In particular, we'll go over the role of the Platform.sh edge layer, and describe in detail how we network hosts and containers together. From the networking perspective, our job is to make sure that a request directed towards your web server reaches the right container, and that container is able to communicate with other containers that your hosted application depends upon, all while making sure that someone else's container cannot talk to one of your containers.

How IKEA Retail standardizes docker images for efficient machine learning model deployment
Posted on October 22, 2023, Level beginner Resource Length long
What do Docker and IKEA Retail have in common? Both companies have changed how products are built, stored, and shipped. In IKEA Retail's case, they created the market of flat-packed furniture items, which made everything from shipping, warehousing, and delivering their furniture to the end location much easier and more cost effective. This parallels what Docker has done for developers. Docker has changed the way that software is built, shipped, and stored, with Docker Images taking up much less space "shelf" space.
