The latest releases of today’s popular Linux distributions include all the tools needed to do interesting things with Linux containers.
For the Makefile MicroVPS project, I set out to build a minimal virtual private server-like environment in a Linux container from scratch.
These are my requirements for the MicroVPS:
Minimal init sequence
Most of what happens in a rc.sysinit file is not needed (or wanted) in a container. However, to work like a virtual private server, the MicroVPS will need some kind of init system. The absolute minimum would be enough to start the network and at least one service.
Native network namespace
The MicroVPS will have a dedicated network namespace. It should be easy to configure.
Native package management
The package set installed in the container image will be managed using native tools like deb or rpm.
Automated build
An automated repeatable build process is a must.
Fast iteration cycle
The building and testing cycle must be fast enough not to drive me insane.
Easy management
It should be easy to distribute, monitor, and run a MicroVPS container.
In this tutorial, I will show how to use the tools included with Linux to build a virtual private server in a Linux container from scratch, using GNU Make to automate the build process.

What is Docker and why should you care? A Docker container is like a
lightweight Virtual Machine. It gives you the benefits of a virtual machine,
isolation of your application, without the drawbacks, having to ship an entire
operating system with your application, slow startup time, and difficult
interaction with the host.
In this presentation you will learn why Docker and containerization is the
future of DevOps and how to use it efficiently. You will learn how to build,
run, and link containers, and what volumes are and what they are used for.
You will also learn about some of the many orchestration solutions that exists
for managing a cluster of containers, both locally and in the cloud.

Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
