创建项目
pom.xml

启动类
@springbootapplication @controller public class dockerapplication { public static void main(string[] args) { springapplication.run(dockerapplication.class, args); } @requestmapping("/user/find") @responsebody public object finduser(){ map<string, string > map = new hashmap<>(); map.put("name", "xdclass.net"); map.put("age","28"); return map; } }
由于harbor没有安装,无法把镜像推到私有镜像仓库上,所以先手动执行。
mvn install,然后把dockerfile和jar包放到一起
[root@topcheer docker]# ll 总用量 16452 -rw-r--r-- 1 root root 168 10月 28 14:24 dockerfile -rw-r--r-- 1 root root 16842487 10月 28 14:17 docker.jar [root@topcheer docker]# cat dockerfile from java:8 volume /tmp add docker.jar app.jar run bash -c 'touch /app.jar' expose 8080 entrypoint ["java","-djava.security.egd=file:/dev/./urandom","-jar","/app.jar"] [root@topcheer docker]#
编译成镜像并启动
