I am trying to launch cassandra container using docker-compose, but stay recieving this error message:

cassandra-server_1  | Connection error: ('Unable to connect to any servers', 
{'127.0.0.1': error(111, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})

Notice that I get it working well when I use directly this command line:

$ docker run -d --name=c1 bitnami/cassandra:3.11.6

And then I ssh the container, and using CQLSH command normaly.

I know it is related to the networking, and I tried everything I was able to without success !

Here is my docker-compose file:

version: '3.4'

services:
  cassandra-server:
    image: 'bitnami/cassandra:3.11.6'
    network_mode: host
    expose:
      - 7000
      - 7001
      - 7199
      - 9042
      - 9142
    ports:
      - '9042:9042'
    command: bash -c 'cqlsh'

I am using the network mode: Host after switching from bridge mode.

Here is my other configuration with bridge mode:

version: '3.4'

networks:
  app-tier:
    driver: bridge
    ipam:
      driver: default
      config:
        - subnet: 172.16.238.0/24

services:
  cassandra-server:
    image: 'bitnami/cassandra:3.11.6'
    networks:
      - aapp-tier
    expose:
      - 7000
      - 7001
      - 7199
      - 9042
      - 9142
    ports:
      - '9042:9042'
    command: bash -c 'cqlsh'

Unfortunately I get the same error message for both configurations.

UPDATE:

When I launch this command:

docker run -it --rm --network app-tier bitnami/cassandra:latest cqlsh --username cassandra --password cassandra

I recieve this error message:
