Hello,
My YAML file is as below:

services:
  dashboard:
    container_name: dashboard
    image: hummingbot/dashboard:latest
    ports:
      - "8501:8501"
    environment:
        - AUTH_SYSTEM_ENABLED=False
        - BACKEND_API_HOST=backend-api
        - BACKEND_API_PORT=8000
    volumes:
      - ./credentials.yml:/home/dashboard/credentials.yml
      - ./pages:/home/dashboard/frontend/pages
    networks:
        - emqx-bridge
  backend-api:
    container_name: backend-api
    image: hummingbot/backend-api:latest
    ports:
      - "8000:8000"
    volumes:
      - ./bots:/backend-api/bots
      - /var/run/docker.sock:/var/run/docker.sock
    env_file:
      - .env
    environment:
      - BROKER_HOST=emqx
      - BROKER_PORT=1883
    networks:
      - emqx-bridge
  emqx:
    container_name: hummingbot-broker
    image: emqx:5
    restart: unless-stopped
    environment:
      - EMQX_NAME=emqx
      - EMQX_HOST=node1.emqx.local
      - EMQX_CLUSTER__DISCOVERY_STRATEGY=static
      - EMQX_CLUSTER__STATIC__SEEDS=[emqx@node1.emqx.local]
      - EMQX_LOADED_PLUGINS="emqx_recon,emqx_retainer,emqx_management,emqx_dashboard"
    volumes:
      - emqx-data:/opt/emqx/data
      - emqx-log:/opt/emqx/log
      - emqx-etc:/opt/emqx/etc
    ports:
      - "1883:1883"  # mqtt:tcp
      - "8883:8883"  # mqtt:tcp:ssl
      - "8083:8083"  # mqtt:ws
      - "8084:8084"  # mqtt:ws:ssl
      - "8081:8081"  # http:management
      - "18083:18083"  # http:dashboard
      - "61613:61613"  # web-stomp gateway
    networks:
      emqx-bridge:
        aliases:
          - node1.emqx.local
    healthcheck:
      test: [ "CMD", "/opt/emqx/bin/emqx_ctl", "status" ]
      interval: 5s
      timeout: 25s
      retries: 5

networks:
  emqx-bridge:
    driver: bridge

volumes:
  emqx-data: { }
  emqx-log: { }
  emqx-etc: { }

The routing table before running containers is as follows:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         172.20.7.52     0.0.0.0         UG    0      0        0 enX0
172.17.0.0      0.0.0.0         255.255.0.0     U     0      0        0 docker0
172.18.0.0      0.0.0.0         255.255.0.0     U     0      0        0 docker_gwbridge
172.19.0.0      0.0.0.0         255.255.0.0     U     0      0        0 br-ec970d30af8f
172.20.0.0      0.0.0.0         255.255.0.0     U     0      0        0 enX0
192.168.64.0    0.0.0.0         255.255.240.0   U     0      0        0 br-ec58823a906e

After running the containers, the table changes as follows:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         172.20.7.52     0.0.0.0         UG    0      0        0 enX0
172.17.0.0      0.0.0.0         255.255.0.0     U     0      0        0 docker0
172.18.0.0      0.0.0.0         255.255.0.0     U     0      0        0 docker_gwbridge
172.19.0.0      0.0.0.0         255.255.0.0     U     0      0        0 br-ec970d30af8f
172.20.0.0      0.0.0.0         255.255.0.0     U     0      0        0 enX0
172.21.0.0      0.0.0.0         255.255.0.0     U     0      0        0 br-352cf9777d39
192.168.64.0    0.0.0.0         255.255.240.0   U     0      0        0 br-ec58823a906e

This causes me to lose connection to the server. I created another YAML file called docker-compose-net-subnet.yml with the following contents:

networks:
  default:
    ipam:
      driver: default
      config:
        - subnet: ${DOCKER_SUBNET}

Then, docker compose -f docker-compose.yml -f docker-compose-net-subnet.yml up -d, but I got the same result.

How to solve it?

Thank you.

What does that mean? Are you talking about a SSH connection? It’s interrupted only temporarily?

Hello,
Thank you so much for your reply.
Yes, my SSH connection to the server is disconnected, but I can’t access other ports either. I can’t even ping the server.
