Question

我已经从maven spring boot应用程序创建了一个docker文件，并创建了一个docker映像并将其推送到我的docker注册表中。

FROM openjdk:8
ADD target/spring-boot-lazy-init-example-0.0.1-SNAPSHOT.jar spring-boot-lazy-init-example-0.0.1-SNAPSHOT.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "spring-boot-lazy-init-example-0.0.1-SNAPSHOT.jar"]

这是我在docker文件中编写并创建docker映像的内容。我已经更改了标签并将其推送到我的Docker中心存储库中，该库将用于Kubernetes集群中的部署目的，但在此之前，我已经将此Docker映像用于测试目的。我已使用此docker映像运行容器，并且由于应用程序默认在8080端口上运行，因此我也完成了端口转发。

ubuntu@dockerimage-vm:~/spring-boot-lazy-init-example$ sudo docker images

我也尝试从本地计算机运行应用程序，并且能够访问URL

但是当我尝试访问在docker容器中运行的应用程序时，我无法访问。我正在从192.168.64.3:8085/lazy访问（8085，因为我已经在该端口进行了端口转发）。

无法访问在Docker容器中运行的Maven Spring Boot应用程序
