Docker Dockerfile JAVA微服务镜像构建Jar

跑java微服务只需要有JDK的环境就行了，直接执行java -jar就行了，就直接可以将java跑起来了

这个是将微服务的jar包直接打进去（只需要有个jdk环境就行）

java:8-jdk-alpine还需要测试，因为环境库可能和centos不一样

[root@localhost java]# cat Dockerfile 
FROM java:8-jdk-alpine
LABEL maintainer www.jar.com
ENV JAVA_OPTS="$JAVA_OPTS -Dfile.encoding=UTF8 -Duser.timezone=GMT+08"
RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories && \
    apk add -U tzdata && \
    ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
COPY hello.jar /
EXPOSE 8888
CMD ["/bin/sh", "-c", "java -jar $JAVA_OPTS /hello.jar"]


[root@localhost java]# docker run -itd jar
