I do not have RPi currently to test, but I am suspicious about RPi's docker-compose...

Anyway - I will mark this as a bug.

Can anybody reproduce this on RPi and confirm that bug exists?

[drasko]

Strange, I just got mail notification from GitHub:
"Can confirm, seeing the same issue on an RPi2." - but I can not see the comment here?

[drasko]

Anyway - All Mainflux Docker images are built by the DockerHub automated build on x64 machines. For RPi packaging we must use ARM compiled images, and that probably means resin.io and Hypriot containers, somethingsimilar to this: https://github.com/hypriot/rpi-golang/blob/master/Dockerfile

Moreover, Mainflux uses EMQ and for the moment I have no idea how will we port this piece of Erlang code to RPi... I guess it can be done, I've seen VerneMQ has been ported to Pine64 few days ago: https://syshell.net/2016/11/05/vernemq-install-it-on-pine64/

We have to see this with EMQ community...

[drasko]

Probably best approach for the first iteration would be to run Mainflux on PC (on Vm for example) connect RPi to this machine in private LAN via ETH and then run Mosquitto on RPi and bridge it similar to this: emqx/emqx#718

I have not tried this set-up yet, but it should work...

@mijicd how will this affect auth? If Mosquitto is bridged to EMQTTD it should be seen like one big cluster, and auth should work correctly.

I managed to bring up mainflux on RPI 3
install gnats alone and mongdb
go get mainflux-core and git clone mainflux-mqtt
build mainflux-core and it run i'll try to see the load testing

[drasko]

@gesaleh great, thanks.

We are wondering about Docker also, please let us know if you have this one running. It will probably demand change in the Dockerfile (maybe to include Hypriot), and if yes, I'd gladly accept PR :)

[drasko]

FYI, I've created https://github.com/mainflux/mainflux/blob/master/install_sources.sh to help installation from the sources.

[drasko]

Closing this one.
