Java Docker&x2013；在docker容器内编译maven项目；从那里开始

我有一个运行Vue和Spring Boot的项目，我需要创建一个

docker compose.yml

文件来运行

mvn clean install

来生成

.jar

，然后从docker容器内的另一个docker文件中构建一个“新”映像

这是完成

mvn清洁安装后需要运行的Dockerfile：

FROM java:8

ENV WKHTML_VERSION 0.12.4

# Builds the wkhtmltopdf download URL based on version numbers above
ENV DOWNLOAD_URL "https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/${WKHTML_VERSION}/wkhtmltox-${WKHTML_VERSION}_linux-generic-amd64.tar.xz"

RUN apt-get update && \
    apt-get install -y --no-install-recommends wget && \
    wget $DOWNLOAD_URL && \
    tar vxf wkhtmltox-${WKHTML_VERSION}_linux-generic-amd64.tar.xz && \
    cp wkhtmltox/bin/wk* /usr/local/bin/ && \
    cp wkhtmltox/lib/* /usr/local/lib/ && \
    rm wkhtmltox-${WKHTML_VERSION}_linux-generic-amd64.tar.xz

# @see https://spring.io/guides/gs/spring-boot-docker/
COPY   server/target/redo-server-0.0.1-SNAPSHOT.jar app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","app.jar"]

因此，构建步骤需要如下所示：


安装node+maven/pull这些映像
安装
postgresql
&拉取该映像
运行
mvn clean install
&生成
.jar
从上面提到的
Dockerfile
构建新映像并运行它

我是新来的
docker compose
，所以我很难按照正确的执行顺序设置它

我之所以需要这样做，是因为生产管道没有运行完整maven应用程序（
Vue.js
和
Spring Boot
app）所需的
节点或npm
，这就是为什么需要从Docker容器内部编译它的原因

如果有人能为我指出正确的方向，我将不胜感激，更不用说——这可能吗
 通过将多步骤构建作为我的Dockerfile来解决。我正在将节点作为依赖项安装到客户端的pom.xml文件中

# Install maven and copy project for compilation
FROM maven:latest as builder

COPY pom.xml /usr/local/pom.xml
COPY server /usr/local/server
COPY client /usr/local/client
WORKDIR /usr/local/

RUN mvn clean install


FROM openjdk:8
ENV WKHTML_VERSION 0.12.4

ENV DOWNLOAD_URL "https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/${WKHTML_VERSION}/wkhtmltox-${WKHTML_VERSION}_linux-generic-amd64.tar.xz"

RUN apt-get update && \
    apt-get install -y --no-install-recommends wget && \
    wget $DOWNLOAD_URL && \
    tar vxf wkhtmltox-${WKHTML_VERSION}_linux-generic-amd64.tar.xz && \
    cp wkhtmltox/bin/wk* /usr/local/bin/ && \

在maven映像中构建需要很多时间。有没有办法缩短这段时间？在maven映像中构建需要很多时间。有没有办法缩短这段时间？
