According to the docker compose file, there is no link between rasa container and duckling container. You’ll need to add `depends_on` key with values of containers you want it to have IP addresses for.

Try updating your docker-compose.yml as

`

```auto
version: '3.0'
services:
  rasa:
    image: bot_main:v4
    ports:
      - "5005:5005"
    depends_on:
      - duckling
      - action_server
  action_server:
    image: bot_action:v1
    ports:
      - 5055
  duckling:
    image: rasa/duckling
    ports:
      - "8000:8000"

```

And try spinning up the instances. You can find more details about the key on the [Compose file reference](https://docs.docker.com/compose/compose-file/)

Edit: Added the action\_server in depends\_on list as well
