Docker development environment CLI. Use for managing containers (start/stop/restart), executing commands in services, viewing logs, and running project scripts from kool.yml.
Kool simplifies Docker-based development with commands for container lifecycle, service execution, and custom scripts.
kool start # Start all services from docker-compose.yml
kool stop # Stop all services
kool restart --rebuild # Restart and rebuild images
kool status # Show running containers
kool exec <service> <cmd> # Run command in service container
kool logs -f <service> # Follow service logs
kool run --json # List available scripts as JSON
kool run <script> # Run a script from kool.yml
Services are defined in docker-compose.yml. Kool wraps docker-compose with simpler commands.
kool start # Start all services
kool start app database # Start specific services
kool start --rebuild # Rebuild images before starting
kool start --foreground # Run in foreground (see logs)
kool start --profile worker # Enable a docker-compose profile
kool stop # Stop all services
kool stop app # Stop specific service
kool stop --purge # Stop and remove volumes (destructive)
kool restart # Restart all services
kool restart --rebuild # Rebuild images on restart
kool restart --purge # Purge volumes on restart
kool status # Show status of all containers
Use exec to run commands inside running service containers (like SSH).
kool exec <service> <command>
kool exec app bash # Interactive shell
kool exec app php artisan migrate # Run Laravel migration
kool exec app npm install # Install npm packages
kool exec -e VAR=value app env # With environment variable
Use docker to run commands in temporary containers (not services).
kool docker <image> <command>
kool docker node npm init # Run npm in node container
kool docker --volume=$PWD:/app golang go build # Mount current dir
kool docker --env=DEBUG=1 python python script.py # With env var
kool docker --publish=3000:3000 node npm start # Expose port
kool logs # Last 25 lines from all services
kool logs app # Logs from specific service
kool logs -f # Follow logs (live)
kool logs -f app worker # Follow multiple services
kool logs --tail 100 # Last 100 lines
kool logs --tail 0 # All logs
Scripts are defined in kool.yml and provide project-specific commands.
kool run --json # List scripts as JSON [{name, comments, commands}]
kool run # List scripts (human-readable)
kool run <script> # Run a script
kool run <script> -- <args> # Pass args (single-line scripts only)
kool run -e VAR=1 <script> # Run with environment variable
All commands support:
-w, --working_dir <path> # Run from different directory
--verbose # Increase output verbosity
docker-compose.yml and kool.yml) or use -w.docker-compose.yml service definitions.kool.yml are not full bash - use kool docker <image> bash -c "..." for pipes/conditionals.
