linux - 为什么一个 linux 命令在容器内运行但在 entrpoint.sh 中不起作用

Question

我使用 ubuntu 16.04 操作系统作为 VM。

在创建容器时，我在 entrpoint.sh 中有一些命令没有按预期工作或表现不佳，但是当我在容器内手动运行时，相同的命令正在工作，准确地说，下面是我的简单 linux cp 命令递归地从源复制到目标并且还解压缩命令。

在我的 entrypoint.sh 中我有三个命令:

  cd /tmp/localization/Tpae7610
  unzip \*.zip
  cp -r /tmp/localization/Tpae7610/*  /home/db2inst1/maximo/

当容器启动时，最后两个命令不起作用，当我说它不起作用时，这意味着它没有给出任何错误，但没有按预期将源内容复制到目的地，也没有解压缩 .zip 文件

注意:但是当我在容器内手动运行时，相同的命令按预期工作。

Answer 1

要么/tmp/localization/Tpae7610/目录下的文件没有权限。

尝试命令 cp -v(verbose 将显示复制的文件) 注释脚本中的 rm -rf localization。然后调试脚本。
