docker 构建时权限被拒绝

Question

我知道有很多标题相似的问题，但没有一个与我的问题相似。我的问题很简单，我正在尝试使用命令

install_packages

在我的 dockerfile 中安装一些软件包。这会导致权限被拒绝错误，指出

/bin/sh: 1: install_packages: Permission denied

我尝试添加

USER 0

和

USER root

但都不起作用。下面是我的 Dockerfile。我究竟做错了什么？。在 github 中也看到了类似的问题，但那里提供的解决方案对我不起作用。 类似问题：https://github.com/bitnami/bitnami-docker-wordpress/issues/230

Dockerfile：（第六条命令出错）

默认情况下，用户路径目录中的

install_packages

文件可能未设置为可执行。您可以尝试使用以下命令使其可执行：

chmod +x /usr/sbin/install_packages
