如何修复 ln -s 在 Docker 中不起作用？

Question

Step 3/10 : RUN mkdir -p /etc/nginx/{sites-available,sites-enabled}
Step 4/10 : COPY nginx.conf /etc/nginx/
Step 5/10 : COPY sites-available/*.conf /etc/nginx/sites-available/
Step 6/10 : RUN ln -s /etc/nginx/sites-available/* /etc/nginx/sites-enabled/
 ---> Running in a2f39a3fd6b3
ln: /etc/nginx/sites-enabled/: No such file or directory
ln: /etc/nginx/sites-enabled/: No such file or directory
ln: /etc/nginx/sites-enabled/: No such file or directory
ln: /etc/nginx/sites-enabled/: No such file or directory
ln: /etc/nginx/sites-enabled/: No such file or directory
ln: /etc/nginx/sites-enabled/: No such file or directory
ln: /etc/nginx/sites-enabled/: No such file or directory
ln: /etc/nginx/sites-enabled/: No such file or directory
The command '/bin/sh -c ln -s /etc/nginx/sites-available/* /etc/nginx/sites-enabled/*' returned a non-zero code: 1

知道为什么这不起作用吗？ ^^ 我在 docker 容器外尝试了所有这些命令，它似乎有效

Answer 1

这可以通过使用以下语句将文件直接复制到 sites-enabled 目录来解决：

COPY sites-available/*.conf /etc/nginx/sites-enabled/

Answer 2

您的第 3 步包含一个 bashism：

mkdir -p /etc/nginx/{sites-available,sites-enabled}

使用默认 /bin/sh，这将创建一个目录而不是您想要的两个目录：

$ docker run -it --rm nginx /bin/sh

# ls -al /etc/nginx

对于/bin/sh，您需要单独列出它们：

# ls -al /etc/nginx
