为什么没有找到，而它确实存在？

Question

$ docker build .

控制台中出现以下错误：

 RUN /provision/provision.sh
 ---> Running in e66928c3c893
/bin/sh: 1: /provision/provision.sh: not found

我的文件夹文件：

/Dockerfile
/provision
/provision/provision.sh

那么，虽然存在/provision/provision.sh，但为什么我会出现/bin/sh:1:/provision/provision.sh:not found错误呢？

COPY provision /provision

Answer 1

provision/provision.sh存在于docker生成上下文（在主机上）中，但您需要首先将其复制(copy)到映像：

COPY provision/provision.sh /provision/provision.sh
# or
COPY provision /provision/
RUN chmod 755 /provision/provision.sh && \
    /provision/provision.sh

正如文件中提到的：

如果 是目录，则复制目录的全部内容，包括文件系统元数据。
