FlashMQ

FlashMQ is a high-performance, light-weight MQTT broker/server, designed to take good advantage of multi-CPU environments.

Builds (AppImage and a Debian/Ubuntu apt server) are provided on www.flashmq.org.

Building from source

Building from source should be done with build.sh. It's best to checkout a tagged release first. See git tag.

If you build manually with cmake with default options, you won't have -DCMAKE_BUILD_TYPE=Release and you will have debug code enabled and no compiler optimizations (-O3). In other words, it's essentially a debug build, but without debugging symbols.

Docker

Official Docker images aren't available yet, but building your own Docker image can be done with the provided Dockerfile.

# It's best to checkout a tagged release. See 'git tag'.
git checkout <tag name>

# build flashmq docker image
docker build . -t halfgaar/flashmq

# run using docker (with, as an example, a place for a config file (default
# name flashmq.conf). Create extra volumes as you need, for the persistence DB
# file, logs, password files, auth plugin, etc.
docker run -p 1883:1883 -v /srv/flashmq/etc/:/etc/flashmq halfgaar/flashmq

# for development you can target the build stage to get an image you can use for development
docker build . --target=build

Plugins

A plugin interface is defined and documented in flashmq_plugin.h. It allows custom authentication and other behavior.

See the examples directory for example implementations of this interface.
