当我在windows 10上运行docker映像时。我得到这个错误:

standard_init_linux.go:190: exec user process caused "no such file or directory"

我的docker文件是:

FROM openjdk:8

EXPOSE 8080

VOLUME /tmp

ADD appagent.tar.gz /opt/app-agent
ADD services.jar app.jar
ADD run.sh /run.sh

# Install compiler and perl stuff
RUN apt-get update
RUN apt-get install -y build-essential
RUN apt-get install -y gcc-multilib
RUN apt-get install -y perl

# Install Percona Toolkit
RUN apt-get install --yes percona-toolkit
RUN ["chmod", "+x", "/run.sh"]
ENTRYPOINT ["/run.sh"]

脚本以#!开头/bin/sh

#!/bin/sh
set -e

JAVA_OPTS="-Dfile.encoding=UTF-8 -Djava.security.egd=file:/dev/urandom"

if [ "${APPD_APP_NAME}" != "" ]; then
JAVA_AGENT="-javaagent:/opt/app-agent/javaagent.jar
fi

exec java ${JVM_OPTS} ${JAVA_OPTS} ${JAVA_AGENT} -jar /app.jar

尝试method1: 试着改变#!/bin/sh到#!/bin/bash但是得到同样的错误。

尝试method2: docker文件中新增dos2unix

RUN apt-get install -y dos2unix
RUN dos2unix /run.sh

当前回答

我只是想补充:对于VSCode用户,您可以通过单击状态栏中的CRLF将CRLF行结束符更改为LF,然后选择LF并保存文件。

我也有同样的问题,这个解决了问题。

其他回答

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。

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。

使用notepad++将CRLF替换为LF

notepad++的查找/替换功能很好地处理了这一要求 好。只需打开替换对话框(CTRL+H),选择 扩展搜索模式(ALT+X),搜索“\r\n”并替换为 “\ n”: 点击全部替换(ALT+A)

重新构建并运行docker映像应该可以解决您的问题。

我在.sh文件的末尾多了一行。我删除了它并修复了这个问题。

这里有多个正确答案。我没有看到它的VIM版本,所以在这里。在VIM中打开文件,检查底部状态行,例如,执行set ff=dos(用于CRLF)或set ff=unix(用于LF)。
