Failed to connect to FIWARE Cygnus 3.8.0

To set up MongoDB and PostgreSQL backends on FIWARE Cygnus 3.8.0, I created the following docker-compose.yml file:

services:

  orion:
    image: telefonicaiot/fiware-orion:3.12.0
    depends_on:
      - mongo
    ports:
      - 1026:1026

  mongo:
    image: mongo:4.4
    ports:
      - 27017:27017

  cygnus:
    image: telefonicaiot/fiware-cygnus:3.8.0
    depends_on:
      - mongo
      - postgres
    environment:
      - CYGNUS_API_PORT=5080
      - CYGNUS_MONGO_SERVICE_PORT=5051
      - CYGNUS_MONGO_HOSTS=mongo:27017
      - CYGNUS_POSTGRESQL_SERVICE_PORT=5055
      - CYGNUS_POSTGRESQL_HOST=postgres
      - CYGNUS_POSTGRESQL_PORT=5432
      - CYGNUS_POSTGRESQL_USER=postgres
      - CYGNUS_POSTGRESQL_PASS=postgres
      - CYGNUS_MULTIAGENT=true
      - CYGNUS_LOG_LEVEL=debug
    ports:
      - 5080:5080
      - 5051:5051
      - 5055:5055

  postgres:
    image: postgres:15
    environment:
      - POSTGRES_PASSWORD=postgres

Then, I run it.

docker compose up -d

I tried sanity check for cygnus. I wanted to get a version of Cygnus.

I got the following error when trying to get a version:

$ curl http://localhost:5080/v1/version
curl: (56) Recv failure: Connection reset by peer

Is there something wrong with my configuration?

The log of Cygnus was as shown:

$ docker compose logs cygnus

Could you please get into cygnus container and check the agent command which is executing?

This is an example:

$ docker exec -u 0 -ti iot-cygnus /bin/bash
root@iot-cygnus:/opt/fiware-cygnus# ps -ax
    PID TTY      STAT   TIME COMMAND
      1 ?        Ss     0:00 /bin/bash /cygnus-entrypoint.sh
      6 ?        Sl     0:22 /usr/bin/java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:6006 -Xmx256m -Xms64m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/cygnus/heapDump -XX:+PrintGCDetails -Xloggc:/var/log/cygnus/gclog -Dflume.root.logger=DEBUG,LOGFILE -Duser.timezone=UTC -Dfile.encoding=UTF-8 -cp /opt/apache-flume/conf:/opt/apache-flume/lib/*:/opt/apache-flume/plugins.d/cygnus/lib/*:/opt/apache-flume/plugins.d/cygnus/libext/* -Djava.library.path= com.telefonica.iot.cygnus.nodes.CygnusApplication -f /opt/apache-flume/conf/agent.conf -n cygnus-ngsi -p 5080

Depending on which sinks are enabled to be configured admin port could be fixed from 5080 to 5089. Since some versions ago we recommend use CYGNUS_SKIP_CONF_GENERATION=true and provide a custom agent.conf by a volume file to cygnus.
