GitHub user leniervm added a comment to the discussion: Problem starting a MQTT
adapter
Successful result, @dominikriemer. The issue was that I had commented out the
NATS service in the docker-compose.minimal.yml file with a # before
understanding the internal flow of the application. Additionally, I believe
there is an error in how the backend service is called:
`# StreamPipes services
backend:
image: "${SP_DOCKER_REGISTRY}/backend-nats:${SP_VERSION}"
depends_on:
- couchdb
environment:
- SP_PRIORITIZED_PROTOCOL=nats
volumes:
- backend:/root/.streampipes
logging: *default-logging
restart: unless-stopped
networks:
spnet:`
Specifically, the $SP_VERSION in the .env files is set to 0.95.1, but on Docker
Hub, it appears as apachestreampipes/backend-nats:0.95.0-SNAPSHOT. We need to
manually modify this to apachestreampipes/backend:0.95.1. Also, in the
extensions-iiotminimal file, there is a `depends-on` attribute without a list,
which we need to correct. Because We can run the compose file.
`extensions-iiot-minimal:
image: "${SP_DOCKER_REGISTRY}/extensions-iiot-minimal:${SP_VERSION}"
depends_on:
logging: *default-logging
restart: unless-stopped
networks:
spnet:`
Lastly, as you mentioned, changing - SP_PRIORITIZED_PROTOCOL=nats is the best
choice for me due to the lightweight nature of the internal communication
broker.
Thanks a lot for your support, have a great day!
