Answer - Armin@netPI - November-27th-2017 We have uploaded a new Docker image that turns your netPI into an MQTT broker: https://hub.docker.com/r/hilschernetpi/netpi-mosquitto-mqtt-broker/ RE: Mosquitto MQTT Broker - C@rlo5Sepulveda - December-15th-2019 Hello Armin, I hope you're doing alright, I am just getting familiar with NetPI, I have some questions but I am going to start asking about Mosquitto MQTT Broker Docker container, the link you shared above does not exists anymore https://hub.docker.com/r/hilschernetpi/n...tt-broker/. I found a Github link: https://github.com/HilscherAutomation/netPI-mosquitto-mqtt-broker but it doesn't work. is there any other option to install Mosquitto container on NetPI?, besides I would like to know if there is a Docker container for NIOT-E-NPIX-4DI4DO or how can I map this I/O Module thru Node-Red? Thanks Carlos RE: Mosquitto MQTT Broker - Armin@netPI - December-16th-2019 Hello Carlos, you are right the Docker image is no more. The reason why I decided to remove the Hilscher docker image for Mosquitto is quite simple. The organizsation Mosquitto itself offer a very official Docker image a long time ago under https://hub.docker.com/_/eclipse-mosquitto. So hence it does not make sense for Hilscher to offer it. So the image to load is "eclipse-mosquitto". As you can read it on the page you need to add the ports 1883:1883 and 9001 :9001 to make it available to the "outside world". If there is something you want to change in the mosquitto.conf file then you can open a console "/bin/ash" in netPI's Docker web GUI and make your edits then usig the editor vi for example Thx Armin RE: Mosquitto MQTT Broker - tad - March-3rd-2021 Dear Armin, I am trying MQTT communication using netPI. I deployed eclipse-mosquitto. I am using "mqtt in" and "mqtt out" nodes in Node-Red. But, status indicator below the nodes shows 'connecting', not 'connected'. If you have any concerns, could you give me some advice? Best regards, RE: Mosquitto MQTT Broker - Armin@netPI - March-3rd-2021 Well for a better view I recommend to all MQTT users to install the tool MQTT-Explorer http://mqtt-explorer.com/ under windows (instead of Node-RED). This tool is for free and much better to explore a running MQTT broker since it monitors ALL topics at once. As next I installed the same eclipse-mosquitto:latest as you did. I also mapped the ports 1883 and 9001 ... and guess what ... the MQTT broker is not reachable via MQTT Explorer. So there seems to be a general problem with the latest version When you click on the container and watch the log file it says: Code: 1614766138: mosquitto version 2.0.7 starting "Starting in local only mode .Connections will only be possible from clients running on this machine" ? I don't know what this means right now. Maybe this is the explanation why it does not reachable from remote machines. I think on the MQTT broker landing page https://hub.docker.com/_/eclipse-mosquitto?tab=description you will find more about this "local" mode. At the moment I am clueless. Earlier version worked well and with no problems at all. Thx Armin RE: Mosquitto MQTT Broker - Armin@netPI - March-3rd-2021 Well I read more details about the very latest version of Mosquitto with a breaking major change due to security reasons here: https://mosquitto.org/documentation/migrating-to-2-0/ This change will have influence on the very latest version of Mosquitto Docker image version 2.x as well and explains, why the images does not work right away. I suppose after deploying the docker container, you need to edit the configuration file in the container manually. Of course it is always possible to load instead of the "eclipse-mosquitto:latest" = 2.x version the old version 1.x with "eclipse-mosquitto:1.6.13" instead RE: Mosquitto MQTT Broker - Armin@netPI - March-3rd-2021 I got it working now also with version 2.x. Based on the documentation at https://mosquitto.org/documentation/migrating-to-2-0/ I added two lines additionally in the mosquitto configuration file in the container named Code: /mosquitto/config/mosquitto.conf The two lines are Code: listener 1883 Then I restarted the container and everything went well. P.S.: I saw in your container screen shot you enabled the "privileged" flag. This is not necessary at all to set for the mosquitto container. Thx Armin RE: Mosquitto MQTT Broker - Armin@netPI - March-3rd-2021 Here is how to edit the configuration file in the container manually using the embedded container console in 7 steps: 1. Click the embedded console icon of the container 2. Choose "/bin/sh" as console terminal service and press connect 3. Call "vi" Linux editor plus the file to edit with "vi /mosquitto/config/mosquitto.conf" 4. Press key "i" in the opening editor to activate the editor mode to "inserting" 5. Insert the lines as first lines in the file "listener 1883" "allow_anonymous true" 6. Press key "Esc" and then ":" then "w" and then "q" which is the command "write quit". 7. Then restart the container Here is a picture of the steps 1 to 5 RE: Mosquitto MQTT Broker - tad - March-3rd-2021 Dear Armin, Thank you very much for your quick and kind response. I tried 2 things according to your information. 1) I loaded eclipse-mosquitto:1.6. 2) I loaded eclipse-mosquitto:latest and modified the file 'mosquitto.conf' to add 2 lines. Both of the above, the MQTT communication worked successfully. I confirmed that from both of the debug view by debug node and MQTT Explorer. I really appreciate your support!!! Best regards, |
