构建java前后端应用程序的通用docker镜像

本文地址：https://www.cnblogs.com/muphy/p/16311465.html

后端

只需要将job映射到/app/app.jar目录就可以使用docker启动

Dockerfile

#FROM anapsix/alpine-java:8_server-jre_unlimited
FROM openjdk:8-jre-alpine

MAINTAINER www.muphy.me

RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

RUN mkdir -p /app /app/logs /app/data

WORKDIR /app

EXPOSE 8080

# 默认设置内存
ENV JAVA_OPTS="-Xms512m -Xmx512m"
# ADD ./xxl-job-admin.jar ./

# CMD sleep 10;java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar app.jar
CMD ["/bin/sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar app.jar"]

构建成镜像java_app

docker build -t java_app .

前端

直接使用ngnix镜像
运行npm run build编译前端项目到dist目录，并将目录中的内容映射到/usr/share/nginx/html目录即可使用docker启动
