This is a command line tool for building and managing isolated development environments based on the Development Container Specification. It functions as an OCI container image builder and a provisioner for instantiating standardized containers within automated continuous integration workflows.
The tool includes a system for injecting pre-configured software and toolsets into containers using a registry of reusable installation modules. This allows for the creation of shareable features and the installation of specific languages, CLI tools, and software dependencies.
It covers the automation of environment bootstrapping, the generation of prebuilt images to reduce startup time, and the execution of commands and lifecycle scripts within running containers. It also handles the mapping of workspace folders to ensure consistent setups across different machines.
