在云代工的Docker中启用HTTPS的Spring Boot应用程序

我创build了一个基于spring的应用程序，它的application.yml文件是这样的： 

server: port: 8108 tomcat: remote_ip_header: x-forwarded-for protocol_header: x-forwarded-proto

它也在https端口上运行。 我部署这个应用程序在云代工，它已成功部署并运行在https url，并正常工作。

现在我用下面的configuration为这个应用程序创builddockerfile： 

 FROM frolvlad/alpine-oraclejdk8 VOLUME /tmp ADD <name-of-jar>.jar aap.jar EXPOSE 8108 ENTRYPOINT ["java","-jar","/aap.jar"]

并使用以下命令将其推送到启用docker的代工厂：

cf push -m 2g –docker-image /：–docker-username

它成功部署并开始，但是当我尝试通过它的URL访问它：

https：//开头

我得到以下例外：

要解决这个问题在我的dockerfile EXPOSE部分我提到了它已经运行的端口443端口，但docker部署失败，并报告与443端口的错误。

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection? 和Error during SSL handshake看起来像您的应用程序正在侦听HTTPS请求，但传入的请求不是HTTPS（请参阅下文）。 看看你的应用程序的configuration，看看为什么。 我没有看到任何与您发布的configuration位相关的信息，这些信息表明为什么启用了HTTPS，但这是通常为Spring Boot应用程序启用HTTPS的configuration。

https://docs.spring.io/spring-boot/docs/current/reference/html/howto-embedded-servlet-containers.html#howto-configure-ssl

对于Cloud Foundry，您的应用程序应该侦听HTTP请求。 目前，外部负载均衡器或GoRouter将终止HTTPS请求，并通过HTTP与所有应用进行通话。

https://docs.cloudfoundry.org/concepts/http-routing.html#tls

如果您希望直接将TLS / HTTPS应用于您的应用程序，那么您当前需要使用TCP路由。

https://docs.cloudfoundry.org/adminguide/enabling-tcp-routing.html#ports

希望有所帮助！
