1.springboot项目打成jar包
mvn install
2.编写Dockerfile
# 基础镜像使用java FROM java:8 # 作者 #MAINTAINER sk # VOLUME 指定了临时文件目录为/tmp。 # 其效果是在主机 /var/lib/docker 目录下创建了一个临时文件，并链接到容器的/tmp VOLUME /tmp # 将jar包添加到容器中并更名为app.jar ADD demo1-0.0.1-SNAPSHOT.jar app.jar # 运行jar包 RUN bash -c 'touch /app.jar' ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
3.把jar包和Dockerfile放在同一个文件夹里（a）
4.进入文件夹然后运行
root@songke-ubuntu:~/Study/IdeaProjects/demo1/a# docker build -t demo1 .
5.等待
root@songke-ubuntu:~/Study/IdeaProjects/demo1/a# docker build -t demo1 .

6.查看
docker images
7.运行
docker run -d -p 8099:8080 demo1
8.输入地址验证
