rmamba / mqtt2redis

Push data from MQTT to Redis

WHAT is mqtt2redis?

This container will update Redis values everytime MQTT data changes. Container includes openvpn client connection so either Redis, MQTT or both can be kept in a secure environment.

MQTT Configuration

You can define MQTT server via env variables like so:

MQTT_SERVER=127.0.0.1
MQTT_PORT=1883
MQTT_USER=
MQTT_PASS=
MQTT_SUB=DDS238/#

The values listed are default so you can only use the env variable if you want to change it. MQTT_SUB accepts string separated by | to listen to multiple paths.

REDIS Configuration

You can define REDIS connection via env variables like so:

REDIS_CONNECTION=redis://localhost:6379
REDIS_USER=
REDIS_PASS=
REDIS_PREFIX=mqtt2redis
REDIS_DB=10

The values listed are default so you can only use the env variable if you want to change it. REDIS_CONNECTION takes user name and password too as redis://user:pass@server:port. REDIS_PREFIX defines the prefix that is appended to path before saved to Redis database.

Docker

Start your container with this command replacing values to match your system:

docker run --name mqtt2redis -v /mnt/cache/appdata/mqtt2redis:/openvpn -e MQTT_SERVER=192.168.13.37 -e MQTT_USER=user -e MQTT_PASS=password -e REDIS_CONNECTION=redis://localhost:6379 -e REDIS_PASS=1337 -e REDIS_DB=10 -d rmamba/mqtt2redis
