# 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 documentation and start docker-compose.

```bash
$ 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.

```bash
$ tail -f log/**/*.log
==> log/dragonfly/cdn/core.log <==

```

### Step 4: Stop dragonfly

```bash
$ docker-compose down
Removing dfdaemon  ... done
Removing scheduler ... done
Removing cdn       ... done
Removing network dragonfly2_default
```
