Using DevContainer CLI to Build Multi-Platform Images with Embedded Features

Development Containers represent a paradigm shift in software development methodology, encapsulating comprehensive development environments within containerized configurations. This approach addresses the imperative need for consistency across diverse development environments by packaging essential tools, libraries, and configurations within self-contained units. Developers can utilize DevContainers to seamlessly share and replicate their development setups, fostering collaboration and enabling a hassle-free onboarding process for new team members. This enhances efficiency, reduces setup time, and mitigates compatibility issues, ultimately streamlining the development workflow.

The DevContainers CLI is a robust command-line interface integral to managing and manipulating development containers. However, nothing is bug-free, and this post details a troubleshooting experience with the DevContainers CLI to build development multi-architecture development container images with embedded features.

GitHub Codespaces and Automatic Port Forwarding

Codespace environments are backed with development containers (dev containers for short). They are supported by other tools, for example, Visual Studio Code.

And even though Microsoft maintains both Dev Containers extension for VSCode and GitHub Codespaces, they behave differently in some aspects.

This article shows one of the bugs, which is related to Automatic Port Forwarding.

Eclipse Can Break Your Code

I have spent an hour today debugging a weird issue: PHPUnit complained that it tried to call an undefined function PHPUnit\Framework\Assert\assertEquals(). Because right now I am working with custom PHP extensions, I suspected that my code somehow corrupted PHP’s internal data structures. But reality prepared me a surprise.

One More Bug in PHP

For the second time in a row, I find a bug in PHP. This time PHP segfaults due to memory corruption during the request shutdown phase.

Found yet Another Memory Leak in PHP

When testing your own PHP extensions, it is very important not to miss any memory leaks. Wherever Valgrind shows a memory leak, you need to check your code for bugs. However, sometimes you can find a memory leak in the PHP Core.
