Rpi MQTT Gateway on Docker

[magpern]

Has anyone successfully installed a raspberry pi Mysensors MQTT Gateway in a docker container?
There is a docker file with a mysensors mqtt online, but it does not work.
And if it where, it is lacking personalization files and config files.

If anyone is interested.. I got MySensors Ethernet Gateway working in a docker container on a RPi, with a radio connected physically to the Pi.

Hi,

I am starting with MySensors to switch my mighthat gateway in near future. Could you share a bit more? I have some experience with docker.

Thanks

@jrbenito I did jump the gun a little early. Sure, the gateway works, if you have externally connected devices, like an external MySensors gateway, but it does not work if you have the radio wired directly onto the RPi. It cannot fint the SPI.

Basically I did this:

A DockerFile (the .configure section needs to be modified to personal preferences)

FROM balenalib/raspberrypi3-debian

RUN apt-get update && apt-get install -y --no-install-recommends git bash make g++ \
  && cd /root \
  && git clone https://github.com/mysensors/MySensors.git --branch development \
  && cd /root/MySensors \
  && mkdir -p /data \
  && LDFLAGS="-static" ./configure --my-transport=rfm69 --my-rfm69-frequency=868 --my-is-rfm69hw --my-gateway=ethernet --my-port=5003 --my-leds-err-pin=29 --my-leds-rx-pin=31 --my-leds-tx-pin=33 --my-rfm69-encryption-enabled --my-signing-request-signatures --my-signing=software --my-config-file="/data/mysensors.conf" \
  && make \
  && cd /root \
  && apt-get remove -y git make g++ && apt-get autoremove -y

EXPOSE 5003

ENTRYPOINT ["/root/MySensors/bin/mysgw"]

And a Docker-compose.yml file (ports needs to be configured. I think 5003 is not needed, since 5003 would be used if the gateway was handling the radio wired to the pins of the pi. Run with serial instead)

version: '3'
services:
  portainer:
    container_name: portainer
    image: portainer/portainer:arm
    restart: always
    volumes:
      - '/var/run/docker.sock:/var/run/docker.sock'
    expose:
      - 9000
    ports:
      - 9000:9000
  
  mysensors:
    build:
      context: .
      dockerfile: Dockerfile
    container_name: mysensor_eth
    restart: unless-stopped
    privileged: true
    devices:
      - /dev/ttyACM0:/dev/ttyACM0
    ports:
      - 5003:5003  
    volumes:
      - /mnt/usb1/mysensorsd/data:/data:rw
      - /sys:/sys:rw
      - /tmp:/tmp

The config file needs to be on a exposed volume and have the eeprom file pointed to the same volume
File mysensors.conf and it needs to be modified for signing keys and path to log aqnd eeprom

i had everything on /mnt/usb1/mysensors and folders data created within that path. I set access to full RW for everyone

I do not use the MySensors on a docker. I had som many problems with it, SPI beeing one, and the LEDs an other.
It literally takes 3 minutes to set it up and run nativelly on a Pi, and this gives you full access to everything.

I run everything else in a docker.

@magpern SPI access in Docker container is possible, you have to use --privileged switch when creating container and some other switches when compiling. I ended up with the following Dockerfile:

FROM raspbian/stretch AS build

WORKDIR /root
RUN apt-get update && apt-get install -y --no-install-recommends git bash make g++ \
  && git clone https://github.com/mysensors/MySensors.git --branch development 
WORKDIR MySensors
RUN echo "##### Building version: $(cat library.properties | grep version | cut -d= -f2)-$(git describe --tags)"
RUN LDFLAGS="-static" ./configure --my-transport=rfm69 --my-rfm69-frequency=433 --my-is-rfm69hw --my-gateway=mqtt --my-controller-ip-address=<ip of the mqtt server> --my-mqtt-user=<user> --my-mqtt-password=<password> --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in  --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18 --my-config-file=/data/mysensors.conf --spi-driver=BCM --soc=BCM2836 --cpu-flags="-mcpu=cortex-a53 -mfloat-abi=hard -mfpu=neon-fp-armv8 -mneon-for-64bits -mtune=cortex-a53" \
  && make

FROM hypriot/rpi-alpine-scratch
RUN mkdir /data
WORKDIR /root
COPY --from=build /root/MySensors/bin/mysgw .

EXPOSE 5003
ENTRYPOINT ["./mysgw"]

I couldn't get ethernet mode to work (I got core dump as soon as client connected to gateway) so I'm using MQTT mode which works great. Here is the relevant run command:

docker run --privileged --volume /opt/mysensors:/data --restart unless-stopped --name mysgw zurajm/mysgw-mqtt-alpine:latest

the mysensors.conf resides in /opt/mysensors:

# Logging
# Verbosity: debug,info,notice,warn,err
verbose=debug

# Enable logging to a file.
log_file=0
# Log file path.
log_filepath=/tmp/mysgw.log

# Enable logging to a named pipe.
# Use this option to view your gateway's log messages
# from the log_pipe_file defined bellow.
# To do so, run the following command on another terminal:
#   cat "log_pipe_file"
log_pipe=0
log_pipe_file=/tmp/mysgw.pipe

# Enable logging to syslog.
syslog=0

# EEPROM settings
eeprom_file=/data/mysensors.eeprom
eeprom_size=1024

# Software signing settings
# Note: The gateway must have been built with signing
#       support to use the options below.
#
# To generate a HMAC key run mysgw with: --gen-soft-hmac-key
# copy the new key in the line below and uncomment it.
#soft_hmac_key=
# To generate a serial key run mysgw with: --gen-soft-serial-key
# copy the new key in the line below and uncomment it.
#soft_serial_key=

# Encryption settings
# Note: The gateway must have been built with encryption
#       support to use the options below.
#
# To generate a AES key run mysgw with: --gen-aes-key
# copy the new key in the line below and uncomment it.
#aes_key=

I only modified eeprom_file location to /data folder.

I hope someone can benefit from it.

BR, Miha

Hi,

I was looking for this!
How can I get this docker container?
Cheers,
