存在的问题:

The problem comes from the .sh file. First we must remember that Windows uses \r\n as the end of the line, while Linux and Mac use \n. Git has a feature called autoclrf that is generally set to “true” on Windows. This automatically converts \n to \r\n upon completion of the download from a Git repository, but Git does not make any kind of notice of this, hence the error is generated. This process is good, at least for the other files, but it is not the case for bash files, as is the case for the entrypoint.sh file.

立即解决方案:

打开您最喜欢的代码编辑器并更改导致冲突的文件的行结束符，在我们的示例中是:entrypoint.sh。你可以在软件右下角的Visual Studio Code中做到这一点，单击CRLF，并将文件行的末尾更改为LF。

git config core.autocrlf false  
git rm --cached -r .   
git reset --hard

这是因为shell脚本是在windows中格式化的，我们需要更改为unix格式。 您可以在任何Linux系统上运行dos2unix命令。

dos2unix your-file.sh

如果你不能访问Linux系统，你可以使用Git Bash for Windows，它带有dos2unix.exe

dos2unix.exe your-file.sh 

在使用下面的代码构建时，我遇到了类似的问题

FROM golang:1.18.0-alpine3.15 AS builder

WORKDIR /go/src/blah
COPY . .

RUN go get -d -v ./...
RUN go install -v ./...

WORKDIR /go/src/blah

FROM centos AS runtime   ## NOTICE THE DISTRO CHANGE HERE
COPY --from=builder /go/bin/blah /bin/blah

CMD ["blah"]

以下是我的解决方案(与上面概述的相同，但添加了供人们检查)

FROM golang:1.18.0-alpine3.15 AS builder

WORKDIR /go/src/blah
COPY . .

RUN go get -d -v ./...
RUN export CGO_ENABLED=0 && go install -v ./...    <== added during install/build

WORKDIR /go/src/blah

FROM centos AS runtime
COPY --from=builder /go/bin/blah /bin/blah

CMD ["blah"]

欢呼。

我在x86机器上基于ARM构建docker映像时遇到了同样的错误消息。这个问题可以通过安装QEMU和注册脚本来解决

#Install the qemu     
sudo apt-get install qemu binfmt-support qemu-user-static packages

#This step will execute the registering scripts
docker run --rm --privileged multiarch/qemu-user-static --reset -p yes 

我在使用阿尔卑斯山图像时也遇到了同样的问题。

我的.sh文件有以下第一行:

#!/bin/bash

Alpine没有bash。所以把这条线改成

#!/bin/sh

或使用

apk add --no-cache bash

帮我解决了这个问题。
