[docker] standard_init_linux.go:190: exec user process caused "no such file or directory" - Docker

When I am running my docker image on windows 10. I am getting this error:

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

my docker file is:

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"]

and the script is start with #!/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

Tried method1: Tried changing #!/bin/sh to #!/bin/bash but getting same error.

Tried method2: added dos2unix in docker file

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

There are multiple right answers here. I don't see the VIM version of it so here it is. Open your file in VIM, check the bottom status line for example, execute set ff=dos (for CRLF) or set ff=unix (for LF).

"No such file or directory" is coming from Linux, and I've seen the following causes:

First cause is not actually having the file inside your container. Some people try to run a command from the host without adding it to their image. Some people shadow their command by mounting a volume on top of the command they wanted to run. If you run the same container, but with a shell instead of your normal entrypoint/cmd value, and run an ls /path/to/cmd you'll see if this exists.

The next cause is running the wrong command. This often appears with json/exec formatting of the command to run that doesn't parse correctly. If you see a command trying to run ["app", or something similar, the json string wasn't parsed by Docker and Linux is trying to use a shell to parse the command as a string. This can also happen if you misorder the args, e.g. trying to run -it is a sign you tried to place flags after the image name when they must be placed before the image name.

With shell scripts, this error appears if the first line with the #! points to a command that doesn't exist inside the container. For some, this is trying to run bash in an image that only has /bin/sh. And in your case, this can be from Windows linefeeds in the script. Switching to Linux/Unix linefeeds in your editor will correct that.

With binaries, this error appears if a linked library is missing. I've seen this often when Go commands that are compiled with libc, but run on alpine with musl or scratch without any libraries at all. You need to either include all the missing libraries or statically compile your command. To see these library links, use ldd /your/app on your binary.

change entry point as below. It worked for me

ENTRYPOINT ["sh","/run.sh"]

As tuomastik pointed out in the comments, the docs require the first parameter to be the executable:

ENTRYPOINT has two forms:

ENTRYPOINT ["executable", "param1", "param2"] (exec form, preferred)

ENTRYPOINT command param1 param2 (shell form)

It's a CRLF problem. I fixed the problem using this:

git config --global core.eol lf

git config --global core.autocrlf input

find . -type f -print0 | xargs -0 dos2unix

Suppose you face this issue while running your go binary with in alpine container. Export the following variable before building your bin

# CGO has to be disabled for alpine
export CGO_ENABLED=0

Then go build

I found a particular edge case where I was using the tini init in an alpine container, but since I was not using the statically linked version, and Alpine uses musl libc rather than GNU LibC library installed by default, it was crashing with the very same error message.

Had I understood this and also taken time to read the documentation properly, I would have found Tini Static, which upon changing to, resolved my problem.

I solve this issue set my settings in vscode.

1. File
   1. Preferences
      1. Settings
         1. Text Editor
            1. Files
            2. Eol - set to \n

Note a similar error such as:

standard_init_linux.go:211: exec user process caused "no such file or directory"

can happen if the architecture an image was built for does not match the one of your system. For instance, trying to run an image built for arm64 on a x86_64 machine can generate this error.

This is because the shell script is formatted in windows we need to change to unix format. You can run the dos2unix command on any Linux system.

dos2unix your-file.sh

If you don’t have access to a Linux system, you may use the Git Bash for Windows which comes with a dos2unix.exe

dos2unix.exe your-file.sh 

in my case I had to change line ending from CRLF to LF for the run.sh file and the error was gone.

I hope this helps,

I had the same issue when using the alpine image.

My .sh file had the following first line:

#!/bin/bash

Alpine does not have bash. So changing the line to

#!/bin/sh

or installing bash with

apk add --no-cache bash

solved the issue for me.

Replacing CRLF with LF using Notepad++

1. Notepad++'s Find/Replace feature handles this requirement quite nicely. Simply bring up the Replace dialogue (CTRL+H), select Extended search mode (ALT+X), search for “\r\n” and replace with “\n”:
2. Hit Replace All (ALT+A)

Rebuild and run the docker image should solve your problem.

I'm unable to comment due to my rep, but I just wanted to add: for VSCode users, you can change CRLF line endings to LF by clicking on CRLF in the status bar, then select LF and save the file.

I had the same issue, and this resolved it.

Add this to your Dockerfile

RUN cat /run.sh | tr -d '\r' > /run.sh
