/bin/bash: invalid optionash: -

Question

I'm new with Docker, so sorry if this is a noob question :(

A friend shared with me his project and I'm trying to create the container but I have an error.

Here is my input:

docker build -t project-py -f project-py/prod/Dockerfile .

And here is the error:

 => ERROR [19/27] RUN build.sh                                                                                     0.2s

 > [19/27] RUN build.sh:
: invalid optionash: -
------
failed to solve with frontend dockerfile.v0: failed to build LLB: executor failed running [/bin/sh -c build.sh]: runc did not terminate sucessfully

What I understand so far is he doesn't understand this line in my build.sh : #!/bin/bash -e

I have done some test:

• leave the build.sh file blank = works
• remove the "-e" = give the error bad interpreter

My friend doesn't have the error...

Here is my Dockerfile:

# based on https://github.com/dockerfiles/django-uwsgi-nginx

Thanks a lot for your help

Answer 1

The file appears to be saved with Windows linefeeds (cr+lf). Save the script with Linux linefeeds (lf) since Linux will interpret the carriage return character as part of the command line.

Answer 2

In Dockfile add this line before RUN ./setup.sh

RUN cat setup.sh | sed '1 s/\r$//' > setup.sh

basically, it will remove \r from the first line.
