Docker-compose MQTT application

[bluedockergirl]

Hi everyone, I was wondering if you could help me with an issue. I'm trying to connect two containers (in the first one there will be a mqtt subscriber, in the second one the broker) in the same host. I am not sure about how to do it. I just created two dockerfiles, one for each container and than created a docker compose file. Could you help me ? I don't know how to continue

Dockerfile Broker: FROM alpine:latest

LABEL Description="MQTT docker image"

RUN apk --no-cache --update add \ mosquitto && \ rm -rf /tmp/ /var/tmp/ /var/cache/apk/*

EXPOSE 1883

ENTRYPOINT ["/usr/sbin/mosquitto"]

Dockerfile Subscriber FROM alpine:latest

RUN apk --no-cache --update add \ mosquitto && \ rm -rf /tmp/ /var/tmp/ /var/cache/apk/* CMD ["subscriber.sh"]

Docker-compose version: "3.12" services: app: build: context: . dockerfile: Dockerfile volumes:

• .:/subscriber ports: 1883:1883 image: app:broker container_name: broker_container networks: virtualobjects: ipv4_address: 10.10.10.11

  app: build: context: ./subscriber dockerfile: Dockerfile ports:

  • "8080:8080/tcp" restart: always image: app:subscriber container_name: sub_container networks: virtualobjects: ipv4_address: 10.10.10.12

  networks: virtualobjects: driver: bridge name: mynet ipam: driver: default config:

  • subnet: 10.10.0.0/16

How does this relate to BigBlueButton and this project (BBB exporter)?
