Docker Container exited with code 0 with no error details

Question

I have written the following docker-compose file to create 3 containers. Bugzilla container exits with code 0 after creation. Could you suggest what am I missing. It's not even showing any error, is there any way I look into exited containers log?

version: "3.2"
services:
  bugzilla:
    build: './bugzilla/'
    container_name: bugzilla
    networks:
      - bugzilla-network
    volumes:
      - ./bugzilla/:/var/www/html/
    depends_on:
      - mysql
    restart: on-failure
  apache:
    build: './apache/'
    container_name: bugzilla-apache
    depends_on:
      - bugzilla
      - mysql
    networks:
      - bugzilla-network
    ports:
      - "8080:80"
    volumes:
      - ./apache/:/var/www/html/
    restart: unless-stopped
  mysql:
    container_name: bugzilla-mysql
    env_file:
      - ./mysql/mysql.env
    networks:
      - bugzilla-network
    image: mysql
    command: --default-authentication-plugin=mysql_native_password
    restart: unless-stopped

networks:
  bugzilla-network:
    driver: bridge

Here's my bugzilla Dockerfile.
