It wraps Docker, Docker Compose, presets, recipes, and deployment-oriented workflows behind a single command-line interface. ### Project history The repository was created on 2020-07-06 and release 1.0.0 was published the same day. The README describes Kool as a way to make modern development environments lightweight, fast, and reproducible while reducing the Docker learning curve. ### Adoption history Kool targets web developers and teams using containers for local development and cloud deployment. Its documentation organizes the project around a CLI, framework presets, Docker Compose files, `kool.yml` scripts, and Kool Cloud deployment configuration. ### How it is used Users start projects with preset-generated configuration, run local containers with Kool commands, execute commands inside services, and keep project scripts in `kool.yml`. Kool documentation also describes `.env` and `.env.local` loading for environment variables. ### Why package nerds care Kool is package-nerd significant as a higher-level wrapper around Docker Compose and Kubernetes-era deployment habits. It represents a recurring package-manager pattern: installing a small CLI that standardizes project-local container workflows across many application stacks. ### Timeline - 2020-07-06: GitHub repository created. - 2020-07-06: 1.0.0 release published. - 2020-07-07: 1.0.1 through 1.0.4 releases published. ### Related projects - Kool is related to Docker, Docker Compose, Kubernetes, Kool Cloud, and framework presets for Laravel, Symfony, NestJS, Next.js, Nuxt.js, WordPress, Hugo, and other web stacks. ### Sources - - - - - ## Security Notes No matching local secret-handling manifest was found for kool.
