在 docker compose 上执行 SQL 脚本

Question

我有一个项目，它在 ./entrypoint.sh 或 docker-compose up 从项目的根目录运行时运行并生成 swagger API 接口，但调用返回条目响应没有数据。

如果我在没有 docker 的情况下在 localhost 上使用 MySQL 运行，则效果很好。我如何加载数据？

入口点.sh

#!/bin/bash

docker network create turingmysql
docker container run -p  3306:3306 --name mysqldb --network turingmysql -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=tshirtshop -d mysql:5.7
docker-compose build
docker-compose up

文件

FROM mysql:5.7

ADD ./database/tshirtshop.sql /docker-entrypoint-initdb.d

#### Stage 1: Build the application
FROM openjdk:8-jdk-alpine as build

# Set the current working directory inside the image
WORKDIR /app

# Copy maven executable to the image
COPY mvnw .
COPY .mvn .mvn

# Copy the pom.xml file
COPY pom.xml .

# Build all the dependencies in preparation to go offline. 
# This is a separate step so the dependencies will be cached unless 
# the pom.xml file has changed.
RUN ./mvnw dependency:go-offline -B

# Copy the project source
COPY src src


# Package the application
RUN ./mvnw package -DskipTests
RUN mkdir -p target/dependency && (cd target/dependency; jar -xf ../*.jar)

#### Stage 2: A minimal docker image with command to run the app 
FROM openjdk:8-jre-alpine

ARG DEPENDENCY=/app/target/dependency

# Copy project dependencies from the build stage
COPY --from=build ${DEPENDENCY}/BOOT-INF/lib /app/lib
COPY --from=build ${DEPENDENCY}/META-INF /app/META-INF
COPY --from=build ${DEPENDENCY}/BOOT-INF/classes /app

ENTRYPOINT ["java","-cp","app:app/lib/*","com.turing.ecommerce.TuringApplication"]

docker-compose.yml

version: '3.7'

  # App backend service
  app-server:

      # Database Service (Mysql)
  mysqldb:
    image: mysql:5.7
    ports:
      - "3306:3306"
    restart: always

    environment:

      MYSQL_ROOT_PASSWORD: root

你有两个 Dockerfile 吗？看起来你构建了自己的 MySQL 容器？

否则，这些不应该成为Java多阶段构建的一部分

FROM mysql:5.7

ADD ./database/tshirtshop.sql /docker-entrypoint-initdb.d

假设您确实在 Docker-Compose 中为 mysql 构建了一个单独的映像，那么您没有使用它，因为您仍然提到image: mysql:5.7

您应该将 SQL 脚本挂载到其中，而不是构建自己的脚本

例如

  mysqldb:
    image: mysql:5.7
    ...
    volumes:
      - db-data:/var/lib/mysql
      - ./database/tshirtshop.sql:/docker-entrypoint-initdb.d/0_init.sql

然后，暂时忘记 Java 服务，并使用 MySQL Workbench 或 mysql CLI 来验证数据是否确实存在。完成后，启动 API
