spring-boot - 无法对 spring 微服务多模块应用程序进行 dockerize

Question

我正在使用 JAVA 11、maven、spring 构建应用程序。
它有一个根 pom 来组织所有子模块，如下所示:
https://github.com/erickmob/spring-petclinic-microservices
这是项目结构:

我试图在根项目上创建这个 docker-compose.yml:

  version: '2'
    services:
      config-server:
        build:
          context: ./config-server
          dockerfile: Dockerfile
        image: config-server
        container_name: config-server
        mem_limit: 512M
        ports:
          - 8888:8888

在 config-server 这个 dockerfile 中:

FROM maven:3.6.3-adoptopenjdk-11 as build

WORKDIR /usr/src/config-server/
COPY . /usr/src/config-server/

RUN mvn clean package

FROM adoptopenjdk/openjdk11:alpine-jre

RUN addgroup -S spring && adduser -S spring -G spring

RUN mkdir -p /files &&  \
    chown -R spring:spring /files

USER spring:spring


VOLUME /files

WORKDIR /app

COPY --from=build /usr/src/config-server/target/config-server-0.0.1-SNAPSHOT.jar /app/app.jar

EXPOSE 8888

ENTRYPOINT ["java", "-jar", "app.jar"]

但它一直给我这个输出错误:

如果我制作 mvn clean安装在根文件夹或 config-server 文件夹上，一切正常，但是当我尝试运行 docker-compose build 时，它给我一个错误，说找不到父 pom。

这是不是 Docker，但 Maven。
您正在构建您的 config-server/仅项目(这里是 Docker 在中间时)，但发送给 Docker 的“上下文”是 只是里面有什么config-server/而不是整个项目。 build config-server/您需要整个项目，因为您正在引用/使用父 POM。
