Question

我正在尝试使用Docker镜像将简单的Spring Boot应用程序部署到Bluemix 该映像基于dockerfile/java:oracle-java8并在我的本地Linux VM上运行完美 - 它在10-30秒内启动但是，在云中运行相同映像的Blumix容器需要10分钟以上才能启动。 Bluemix控制台页面显示状态为Running，但过去10分钟没有进度（按日志判断）。我使用sudo ice logs -o myContainer命令获取以下日志（注意时间间隔）：

使用sudo ice inspect myContainer我得到：

最初我使用ice run myContainer myImage启动容器。我停下来启动了容器，但它没有解决问题。

以下是Docker文件的内容：

FROM dockerfile/java:oracle-java8
ADD myJar-0.0.1.jar /opt/myFolder/
ADD application.properties /opt/myFolder/
EXPOSE 8080
WORKDIR /opt/myFolder/
CMD ["java", "-jar", "-Xmx1500m", "myJar-0.0.1.jar"]

Answer 1

将端口绑定到您的应用程序似乎存在问题。

在Dockerfile中，您需要以下内容。

EXPOSE

其中port为22,80,443,9080或9443。

此外，您需要定义一个命令来启动您的应用程序。

CMD [ “....”]

这是https://www.ng.bluemix.net/docs/#services/Containers/index.html的第6步。

Bluemix很慢启动Spring Boot应用程序，挂起
