在Docker映像中找不到文件

虽然我不是很喜欢Docker，但是我却在为找不到文件的问题而苦苦挣扎。 我添加了一个ls命令来显示文件是否确实存在。有时是，有时不是，但总是会发生“文件丢失”错误。

我正在Win10-2004上运行Docker Desktop Community V 2.0.0.3（31259）

构建库时出错：

Dockerfile：

ADD ./build_opus.sh /usr/local/sbin/

#added for debugging
RUN cd /usr/local/sbin && ls

RUN IFS=" " &&
for arch in $TARGET_ARCHS;
do
./build_opus.sh ${arch};
done

输出：

The command '/bin/sh -c IFS=" " && for arch in $TARGET_ARCHS; do .usr/local/sbin/build_opus.sh ${arch}; done' returned a non-zero code: 127

有人有主意吗？

.sh文件以启动docker：

您将#include <stdio.h> int main(void) { char name[ 100 ]; int counter; int size; int patrol = 0; for (counter = 0; counter < size; counter++, patrol++) { name[ counter ] = getchar(); size = sizeof(name); if (10 == name[ counter ]) { break; } } for(counter = patrol; counter >= 0; counter--) { printf("%c", name[ counter ]); } printf("\n"); return 0; }// end of main 与WORKDIR混淆了。在docker中，有一个名为WORKDIR的概念，其作用类似于cd。它将目录位置从此更改为所有后续指令。当指令到达下一层时，使用cd只会更改该特定层中的目录，该目录位置将恢复为cd。

因此，为了正常运行，您需要使用脚本的绝对路径或使用 WORKDIR 进行更改，然后运行脚本。

使用绝对路径：

WORKDIR

使用“ WORKDIR”：

RUN IFS=" " &&
for arch in $TARGET_ARCHS;
do
/usr/local/sbin/build_opus.sh ${arch};
done

参考：

  1. WORKDIR in docker
  2. difference between RUN cd and WORKDIR in Dockerfile
