VSHN.timer #166: Happy New Containers in 2023!

9. Jan 2023

Welcome to another VSHN.timer! Every Monday, 5 links related to Kubernetes, OpenShift, CI / CD, and DevOps; all stuff coming out of our own chat system, making us think, laugh, or simply work better.

This week we’re going to talk about the state of the container world at the beginning of this new year.

1. Microsoft recently published the Develoment Containers open specification. It explains how to use a container as a full-featured development environment, run an application, and aid in continuous integration and testing. Will it become a standard?


2. WebAssembly is a relatively new technology that allows you to compile application code written in many languages, such as Rust, C, C++, JavaScript, and Golang, and run it inside sandboxed environments, like web browsers and now alongside containers in Docker, too! Check out the official documentation for more details.


3. Toru Komatsu, a senior engineer at GitPod, has been exploring the possibility of developing a container runtime using Rust. As a result, we now have youki, the OCI container runtime in Rust, to compete with runc and crun. Check out this presentation from KubeDay Japan!


4. Docker and Podman are great container engines and serve the same purpose in building, running, and managing containers. But which one should you choose? This article will give you a much better understanding of both.


5. This is a Docker base image that can quickly create containers to run any X application on a headless server. The application’s GUI is accessed through a modern web browser (no installation or configuration needed on the client side) or via any VNC client.


Are a Podman or a Docker user? Are you already running WebAssembly applications in your clusters? Would you like to share some container tips and tricks with our readers? Get in touch with us, and see you next week for another edition of VSHN.timer.

PS: check out our previous VSHN.timer editions about containers: #12, #17, #40, #51, #54, #71, #81, #108, #124, #144, and #151.
