Question

我正在尝试使用初始化脚本启动docker MySQL容器。我的Dockerfile看起来像这样：

FROM node:11
WORKDIR /usr/src/app
COPY ./init.sql /docker-entrypoint-initdb.d/
COPY . .
RUN npm install
ENV PORT=8000
EXPOSE ${PORT}
CMD [ "npm", "start" ]

我将init.sql文件放在两个位置，分别是主目录和docker-entrypoint-initdb.d /文件夹。 init.sql文件仅具有create table和insert语句。我按以下顺序运行Docker命令：

//start network
docker network create --driver bridge mysql-net

//launch docker mysql container with init script to create tables & data
docker run -d --name mysql-server --network mysql-net -p 3306:3306 -e "MYSQL_ROOT_PASSWORD=rootpassword" -e "MYSQL_DATABASE=yelplikeapp" -e "MYSQL_USER=yelplikeapp" -e "MYSQL_PASSWORD=hunter2" -v "/c/Users/marti/Documents/projectFolder:/docker-entrypoint-initdb.d" mysql:5

启动mysql-server容器最初是可以的，但是当我运行'docker ps -a'几秒钟后，我可以看到它一启动就退出：

为什么我的mysql服务器容器退出？我一直试图进入容器并查看数据库，以验证是否成功创建了所有表。但是我在这样做时遇到了麻烦，并认为这是问题的根源。

为了透明起见，我将发布完整的init.sql文件：当我检查mysql-server的日志时，有一条错误消息说第1行的错误1050（42S01）：表“用户”已存在

解决了这个问题，我从dockerfile中删除了copy语句，还删除了init.sql文件。在我的项目文件中有两个，在homeRepo / init.sql和homeRepo / docker-entrypoint-initdb中有一个.d /

我删除了homeRepo / init.sql文件，重新运行了docker mysql-server创建的创建，并且工作正常

docker mysql容器启动后退出
