C++ development container for VS Code that supports both Docker and Podman.

This devcontainer provides a reproducible C++ build environment using CMake, and can be used with either Docker or Podman as the container runtime.

Features

• Works with VS Code Dev Containers
• Supports Docker and Podman
• Non-root user inside container
• UID/GID matching with host
• Forwards host SSH keys for Git access

---

Requirements

• VS Code
• Dev Containers extension
• Docker or Podman installed on Host

Prerequisite

Using with Podman

Make sure that podman is installed and accessible
