Question

我目前正在使用Docker（或尝试使用Docker），所以我设置了一个webapp。我使用Eclipse创建了一个maven项目，构建了一个.war文件，并将其部署在Glassfish服务器上（以检查其是否有效）。这行得通，我可以通过

访问webapp

localhost:8080/myApp

现在我创建了一个Dockerfile，从中创建了一个Docker映像，并通过

docker run -d -p 8080:8080 myApp

这也有效，并且

docker ps -a

显示容器正在运行。但是，当我尝试立即访问localhost：8080 / myApp时，我得到

ERR_CONNECTION_REFUSED

我用Chrome，Firefox和Internet Explorer尝试过。

docker exec -it <myContainer> bash

为我在容器内提供了一个外壳（如预期）。当我这样做

curl -v localhost:8080/myApp

在这里，我得到了期望的输出（来自myApp的页面）。

所以对我来说，这意味着容器正在运行，glassfish服务器正在容器内部运行，并且myApp已“正确”部署到了该服务器，但仍然无法从容器外部访问myApp。

docker ps -a

顺便说一句，

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                                                                       NAMES
9514b1ab6dd0        myApp              "sh /start.sh"      9 minutes ago       Up 9 minutes        4848/tcp, 8181/tcp, 0.0.0.0:8080->8080/tcp   admiring_cori

Dockerfile当然包含该行

EXPOSE 8080

任何想法在这里可能出什么问题吗？

编辑：

这些是Dockerfile的内容：

FROM glassfish:4.0

COPY myApp.war /
COPY start.sh /


EXPOSE 8080

RUN ["chmod", "+x", "/start.sh"]

ENTRYPOINT ["sh", "/start.sh"]

start.sh：

#!/bin/sh

/usr/local/glassfish4/bin/asadmin start-domain
/usr/local/glassfish4/bin/asadmin -u admin deploy /myApp.war
/usr/local/glassfish4/bin/asadmin stop-domain
/usr/local/glassfish4/bin/asadmin start-domain --verbose

编辑2：

docker logs <container>

收益
