我正在尝试创建一个混合容器。 以下是我的码头工人撰写文件。
version: "2"
services:
database:
build:
context: ./registration-database
image: registration-database
# set default mysql root password, change as needed
environment:
MYSQL_ROOT_PASSWORD: password
# Expose port 3306 to host.
ports:
- "3306:3306"
restart: always
webserver:
build:
context: ./registration-webserver
image: registration-webserver
# mount point for application in tomcat
volumes:
- ./app/target/UserSignup:/usr/local/tomcat/webapps/UserSignup
links:
- database:registration-database
# open ports for tomcat and remote debugging
ports:
- "8080:8080"
- "8000:8000"
restart: always
以下是 dockerFile for mysql：
FROM mysql:5.7
# Copy the database initialize script:
# Contents of /docker-entrypoint-initdb.d are run on mysqld startup
ADD docker-entrypoint-initdb.d/ /docker-entrypoint-initdb.d/
ENV MYSQL_DATABASE=ishan
ENV MYSQL_USER=ishan
ENV MYSQL_PASSWORD=password
以下是initialize_db.sql文件
USE `ishan`;
CREATE TABLE `user` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`dateOfBirth` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP ,
`emailAddress` varchar(255) NOT NULL,
`firstName` varchar(255) NOT NULL,
`lastName` varchar(255) NOT NULL,
`password` varchar(8) NOT NULL,
`userName` varchar(20) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=43 DEFAULT CHARSET=latin1;
早些时候，当我运行命令时，docker-compose up它正在创建用户ishan并且还创建了user表。但是现在，突然发生了一些事情，尽管 mysql 与根用户一起安装，但新用户 (ishan) 和表没有被创建。任何帮助，不胜感激。
以下是启动时打印的日志：

很可能您的卷仍然存在，因此MySQL忽略入口点文件夹。您需要在运行之间删除卷才能重新开始。请注意，这意味着在此期间丢失保存在mysql中的数据。
docker-compose down
# this will clean all volumes not in use by any containers
docker volume prune
运行docker volume ls以确保您的卷已消失，然后再次运行您的 docker 撰写。
