## Running the server
Dragonfly runs on linux. It uses relatively new linux specific [io-uring API](https://github.com/axboe/liburing)
for I/O, hence it requires Linux version 5.11 or later.
Ubuntu 20.04.4 or 22.04 fit these requirements.

### With docker:

docker pull ghcr.io/dragonflydb/dragonfly:latest && \
docker tag ghcr.io/dragonflydb/dragonfly:latest dragonfly
docker run --network=host --rm dragonfly
docker run --network=host --ulimit memlock=-1 --rm dragonfly
```
Some hosts may require adding `--ulimit memlock=-1` to `docker run` options.
*You need `--ulimit memlock=-1` because some Linux distros configure the default memlock limit for containers as 64m and Dragonfly requires more.*
