springBoot项目生成docker镜像并运行在docker

• Dockerfile文件编写

Dockerfile 文件如下

FROM java:8
EXPOSE 80

ENV LANG C.UTF-8
ENV JAVA_OPTS=""
#时区
ENV TZ=Asia/Shanghai
#jar包名
ENV JAR=edu-bc-admin.jar
#工作路径
ENV WORKDIR=/opt/big-class/admin/

VOLUME /tmp
ADD $JAR $WORKDIR$JAR
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone \
&& echo "export LC_ALL=zh_CN.UTF-8"  >>  /etc/profile

WORKDIR $WORKDIR
ENTRYPOINT ["sh", "-c", "java $JAVA_OPTS  -Djava.security.egd=file:/dev/./urandom -jar $JAR"]

• 执行脚本生成镜像

docker build -t big-class/edu-bc-admin .

• 运行镜像生成容器,可以用docker run 或者 docker-compose或者其他编排工具

docker-compose.yml文件如下

version: '2'
services:
  edu-bc-admin-prod:
    image: big-class/edu-bc-admin
    container_name: edu-bc-admin-prod
    restart: always
    expose:
     - 80
    ports:
      - "8082:80"
    volumes:
      - /opt/big-class/admin:/opt/big-class/admin
      - /opt/big-class/admin/logs:/opt/big-class/admin/logs
    environment:
      - spring.profiles.active=prod
      - JAVA_OPTS=-Xmx512m -Xms512m
