准备springboot项目
使用maven install打包,idea会将其发布到maven仓库,直接用就好。或者会在target目录中。
本地测试确保springboot的jar包没问题
Dockerfile方式部署springboot
如果我们不使用docker容器的,那么我们正常发布就是java -jar跑起来。
现在只是我们编写脚本生成镜像运行,而编写脚本的内容,还是怎么运行java -jar。
FROM java:8
MAINTAINER sunpy
COPY ./teacher-service-0.0.1-SNAPSHOT.jar /teacher-service.jar
ENTRYPOINT ["java","-jar","teacher-service.jar"]
上面要确保,当前目录里面存在teacher-service-0.0.1-SNAPSHOT.jar文件。
生成镜像:
[root@ecs-140051 app]# docker build -t teacher-service:v2 .
