Docker entrypoint file "no such file or directory"

I have a container using a docker image as part of a project that works fine on my other Windows machine (and a few other developers' machines). When upping the project on my secondary Windows machine however the entrypoint file is reported as not found

$ docker-compose logs -f php
Attaching to project-name-php-1
project-name-php-1 | exec /usr/local/bin/docker-entrypoint: no such file or directory

I've confirmed the syntax in the Dockerfile as I had seen comments from people who had used single quotes incorrectly (not that I would expect such an error given it works fine on other machines)

ENTRYPOINT ["docker-entrypoint"]

I have also confirmed that file does actually exist within the image

docker run -it --rm --entrypoint bash theimage/inuse:thetag
root@209618ad969c:/var/www# ls -l /usr/local/bin
-rwxr-xr-x 1 root root      924 Jul 22 12:04 docker-entrypoint

The file isn't set in the container via volume mount or anything I can see, so I am out of ideas as to why the file is not found when permissions etc look correct to me.

Solution

  • In the end my IDE (PHPStorm) was set to system dependent line endings, and was inserting Windows endings (\r\n) instead of unix line endings (\n), despite the file within the image seeming not to have the resulting issue.

    Changing the setting and saving the affected files resulted in the entrypoint functioning correctly.
