#基础镜像
FROM adoptopenjdk/openjdk8-openj9:alpine-slim

#设置时区与时间
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >/etc/timezone

#项目jar包引入
COPY *.jar  /app.jar

#指定交互端口
EXPOSE 8082
EXPOSE 9092

CMD ["-web", "-webAllowOthers", "-tcp", "-tcpAllowOthers", "-ifNotExists"]

#启动脚本
ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-Xshareclasses", "-Xquickstart", "-cp", "/app.jar", "org.h2.tools.Server"]
