GitHub Codespaces

Cloud-hosted development environments on GitHub, configured by a devcontainer.json file.

Definition

Codespaces run in VMs with VS Code in the browser or desktop, giving every contributor a consistent, preconfigured environment. Dev containers define tools, extensions, and ports.

Example

.devcontainer/devcontainer.json installs Python 3.12 and the Ansible extension.

Exam tip

Dev container configuration is stored in the repository under .devcontainer.
