Question

我创建了一个基于spring boot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。我在云代工厂中部署了这个应用程序，它已成功部署并运行在https网址上，并且工作正常。

现在我使用以下配置为此应用程序创建了dockerfile：

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

使用以下命令将docker启用到云代工厂：

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

它已成功部署并开始使用，但当我尝试通过其URL访问它时：

的https：//

我得到以下异常：

要在我的dockerfile EXPOSE部分中解决此问题，我提到443端口，它已经运行它的端口，但是docker部署失败并报告443端口错误。

Answer 1

javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?和Error during SSL handshake看起来您的应用正在侦听HTTPS请求，但传入的请求不是HTTPS（请参阅下文）。查看应用程序的配置以了解原因。我没有看到你发布的配置的任何内容，这表明为什么启用了HTTPS，但这是通常为Spring Boot应用程序启用HTTPS的配置。

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与所有应用程序通信。

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

如果您希望将TLS / HTTPS直接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！
