Error Mosquitto Docker

[IgnacioAnguita]

Hi,

When running the ./services start command I get the following error on the Mosquitto Container. Is able to start the rest of the containers except the mosquitto one. No errors on services create.

This issue is due to mounting a Docker volume using windows. The relevant docker-compose line is here: https://github.com/FIWARE/tutorials.IoT-over-MQTT/blob/master/docker-compose.yml#L148

 volumes:      
      - ./mosquitto/mosquitto.conf:/mosquitto/config/mosquitto.conf

If the existing bash script isn't working with your specific O/S, you will need to change this statement to hard-code your volume location c:\FIWARE\tutorial_mqtt/tutorials.IoT-over-MQTT - try looking at How to Create (and Manage) Docker Volumes on Windows for inspiration.
