coexistence of `command` and `tty: true`

[hamadatakaki]

I want to keep launching the server using docker-compose.
but I want to use command | entrypoint when I launched the server.

I wrote docker-compose.yml as follows.

version: '3'
services:
  db: ##pass##

  web:
    build: .
    ports:
      - "8000:8000"
    command: echo "entry!!"  # this is dummy command
    depends_on:
      - db
    tty: true
    stdin_open: true

However, the server stopped if it was up.

Please help me.
Can anyone teach me about how to solve this problem?
(sorry, I'm Japanese student. I am not good writing in English. 😇
