Question

我第一次运行 docker-compose up 时，docker 创建了组件，但是，当我只想启动容器并运行 docker-compose start 时重新启动后，我收到以下错误：

ERROR: for mysqldb  Cannot start service db: OCI runtime create failed: container with id exists: xxxxxxx

如果我删除容器并再次运行 docker-compose up 它可以工作，但是每次我重新启动计算机时我都必须重新创建容器，这是为什么？过去我可以通过运行 docker-compose start 来挂载容器，而现在我似乎每次都必须重新创建它们。

我创建了以下 docker-composer.yml：

version: '3.3'

services:
  # Database
  db:
    image: mysql:5.7
    container_name: mysqldb
    volumes:
      - db_data:/var/lib/mysql
    restart: always
    environment:
      DB_HOST: localhost
      MYSQL_ROOT_PASSWORD: testing
      MYSQL_DATABASE: testing
      MYSQL_USER: root
      MYSQL_PASSWORD: testing
    networks:
      - testingnetwork

如果我在环境中为 MYSQL_USER 设置“root”，我会收到错误消息。然后我改了MYSQL_USER：测试，效果很好。

Docker-composer 错误：无法启动服务数据库：OCI 运行时创建失败：具有 ID 的容器存在
