Dev Containers

Overview

Dev containers define reproducible development environments using a devcontainer.json file. They are the foundation of GitHub Codespaces and work with VS Code Dev Containers, the devcontainer CLI, and DevPod.

File Location

Place devcontainer.json in one of:

• .devcontainer/devcontainer.json (preferred)
• .devcontainer.json (repo root)
• .devcontainer/<folder>/devcontainer.json (multiple configs)
