docker-rtl433
merbanan/rtl_433 in docker!
General Description
This image provides both an MQTT publishing image (:latest/:mqtt) and a base image that simply compiles rtl_433 for further use (:base)
You can find the full source and documentation at https://github.com/merbanan/rtl_433.
For this to work at all the hardware host that you are running docker on requires one or more RTLSDR USB dongles plugged in.
Base Image:
Available by executing the command docker pull va7eex/rtl433:base
This justs builds rtl_433 in alpine for use in other containers so I don't have to constantly reduplicate my work.
Example dockerfile based upon this:
FROM va7eex/rtl433:base
ENV DATATYPE="csv"
ENV LOGNAME="environment.csv"
ENTRYPOINT rtl_433 -F $DATATYPE:/tmp/$LOGNAME -T 60 && cat /tmp/$LOGNAME
MQTT publisher
Available by executing the command docker pull va7eex/rtl433:latest
This image will connect to an MQTT broker and publish all data it can receive and process to various topics under senors/rtl_433/$deviceType/$deviceID/#.
