docker-compose 中的 MySQL 错误：[错误] [入口点]：无法启动服务器。 mydb 退出，代码为 0

Question

我正在尝试使用此

docker-compose.yml

文件运行 MySQL 容器：

version: '3.3'

services:
  mydb:
    container_name: mydb
    image: mysql:8.4.0 # I also tried lts and latest here
    restart: unless-stopped
    environment:
      MYSQL_DATABASE: somedb
      MYSQL_USER: myuser
      MYSQL_PASSWORD: mysomepass
      MYSQL_ROOT_PASSWORD: somepass
    networks:
      - my_network 
    volumes:
      - ./data:/var/lib/mysql
    ports:
      - "3306:3306"
# I've created the network and it seems fine
networks:
  my_network:
    external: true
    driver: bridge

它在我自己的计算机（Ubuntu 22.04 桌面）上完美运行，但是当我尝试在服务器（Ubuntu 22.04 服务器）上运行完全相同的撰写时，我收到此错误：

看起来像是内存问题。当容器被杀死而没有任何其他错误消息时，最常见的情况是。
