.dockerignore无法将文件包含在具有！**/*.extension模式的子目录中 [英] .dockerignore fails to include files in subdirectories with !**/*.extension pattern

问题描述

我遇到了 .dockerignore 文件.这是我的项目结构:

I'm having trouble with the .dockerignore file. This is my project structure:

file.sh
file.js
file.go
file.py
subdir/
    file2.go
    file2.py
.dockerignore
Dockerfile

根据 .dockerignore 文档:

(...)，您可能想要指定要包含在上下文中的文件，而不是要排除的文件.为此，将*指定为第一个模式，然后指定一个或多个！异常模式.

(...) you may want to specify which files to include in the context, rather than which to exclude. To achieve this, specify * as the first pattern, followed by one or more ! exception patterns.

并且:

以！开头的行(感叹号)可用于排除例外情况.

Lines starting with ! (exclamation mark) can be used to make exceptions to exclusions.

最后:

Docker还支持特殊的通配符字符串**，该字符串与任意数量的目录(包括零个)匹配.例如，**/*.go将排除在所有目录(包括构建上下文的根目录)中找到的所有以.go结尾的文件.

Docker also supports a special wildcard string ** that matches any number of directories (including zero). For example, **/*.go will exclude all files that end with .go that are found in all directories, including the root of the build context.

基于此，这是我的 .dockerignore 文件:

Based on that, this is my .dockerignore file:

# ignore everything
*

# whitelist
# ---------

# python files
!**/*.py

构建并运行容器并检查文件时，我得到了:

When I build and run the container and inspect the files, I get this:

file.py

缺少 subdir 目录，应该包含 subdir/file2.py .如果我在 .dockerignore 中添加！subdir/**/.py ，它会起作用，但是我的想法是在其中包含任何 .py 文件任何子目录.

The subdir directory is missing, subdir/file2.pyshould be included. It works if I add !subdir/**/.py to my .dockerignore, but the idea is to include any .py file in any subdirectory.

这是容器中应该存在的文件结构:

This is the file structure that should be present in the container:

file.py
subdir/
    file2.py

这是怎么回事?

推荐答案

我发现了一些提到此确切问题的问题，例如:

I found a few issues that mention this exact problem, like these:

.dockerignore中的异常模式不支持通配符目录 dockerignore不尊重特殊通配符**" (评论)

似乎很快就不会修复:(

And it seems like it's not gonna be fixed any time soon :(
