I’m trying to run this project/image with Docker Toolbox

# docker-machine -v

docker-machine.exe version 0.14.0, build 89b8332

# docker-compose -v

docker-compose version 1.20.1, build 5d8c71b2

# docker -v

Docker version 18.03.0-ce, build 0520e24302

# docker-compose up

Everything works as expected

# docker-compose down

But, when I try to build the image and run (instead of using the official image):

# docker build -t novosga:2.0.0-RC3 .

Change docker-compose.yml to use novosga:2.0.0-RC3

# docker-compose up

novosga_1 | /usr/local/bin/docker-php-entrypoint: 9: exec: start.sh: not found

More info:

# docker run -it --rm novosga/novosga sh -c 'ls -la /usr/local/bin'

The file start.sh is there with same contents, but with diferente sizes.

Can someone reproduce this?

What’s your host OS? How did you get the source?

https://github.com/novosga/docker/blob/master/novosga-2.0/start.sh says it’s 875 bytes, which matches what’s in the official image. But if you have a Windows host, and your copy of the source has DOS CR+LF line endings, that file has 29 newlines, and if there are 29 extra carriage return bytes, that adds up to 904 bytes, which matches your image. When the image actually runs, it’s on a Linux VM, which expects only Unix LF line endings, so it’s trying to run /bin/sh^M as an interpreter and not finding it, hence the “command not found” error.

Just a guess, but…

Hello, thank you for your quick reply!
I’m running Docker Toolbox for Windows 10, I did

# git clone https://github.com/novosga/docker.git

I’ve openned this project with Visual Studio Code and created the docker-compose.yml, I didn’t modify others files.
I’m using Git for Windows.

EDIT: I’ve changed line endings to LF (Unix Style) and it’s ok now. Thank you!
