Docker构建挂起。我怎么看发生了什么事？ [英] Docker build hangs. How can I see what is going on?

问题描述

此Dockerfile在下载完成后挂起：

 从Ubuntu：18.04 
 MAINTAINER Dean Schulze 
 
 ENV JS_CE_VERSION 7.1.0 
 ENV JS_CE_HOME / opt / jasperreports-server-cp-$ {JS_CE_VERSION} 
 ENV路径$ PATH：$ {JS_CE_HOME} 
 
运行apt-get update&& apt-get install -y wget \

&& ;易于清洁
 
 EXPOS 8080 
 
 CMD ctlscript.sh start&& tail -f / dev / null 
  

输出的最后几行是

如何诊断像这样挂起的Docker构建？

编辑

以下是请求的输出：

它看起来这些行是相反的，最后执行的是 ENV PATH 。下一行是 RUN 行，该行具有多个由&& 分隔的命令。

这是对DockerHub上的Dockerfile的修改。我更改了ubuntu版本和正在安装的应用程序的版本。

我应该提交错误报告吗？

解决方案

我可以通过回滚到 ubuntu 16.04 来工作。 18.04 中必须进行一些更改，导致此Dockerfile失败，或者 ubuntu 18.04 映像省略了某些内容。 / p>

This Dockerfile hangs after the download has completed:

The last few lines of output are

How do I diagnose a docker build that hangs like this?

Edit

Here's the requested output:

$ docker image history d5d47e51eafc

It looks like the lines are in reverse order and the last one executed is the ENV PATH. The next line would be the RUN line which has multiple commands separated by &&.

This is a modification of a Dockerfile on DockerHub. I changed ubuntu versions and the version of the app being installed. That shouldn't have broken anything.

Should I file a bug report?

解决方案

I got this to work by rolling back to ubuntu 16.04. There must be some change in 18.04 that causes this Dockerfile to fail, or maybe the ubuntu 18.04 image omitted something.
