Development

Easily set up a local development environment.

Step 1: Install docker and docker compose

See documentation on docs.docker.com

Step 2: Start dragonfly

Enter dragonfly project and start docker-compose.

$ docker-compose up
Creating network "dragonfly2_default" with the default driver
Creating cdn ... done
Creating scheduler ... done
Creating dfdaemon ... done
Attaching to cdn, scheduler, dfdaemon

Step 3: Log analysis

Show dragonfly logs.
