Shell script fails on Docker for windows

I'm facing a problem trying to run an image on Docker for Windows.

I have a Dockerfile like this:

FROM openjdk:8-jre-alpine
WORKDIR /myworkdir
COPY path/tomyproject/src/main/bin/start /myworkdir/start
...
EXPOSE 8080

CMD [ "sh", "/myworkdir/start" ]

And here is a piece that fails on "start" file:

#!/bin/sh

SCRIPT="$0"
# set the environment variables received from the command line
for i; do
case "$i" in
  *=*) echo $i ;
  key=${i%=*}
  value=${i#*=};
  export $key=$value
esac
done

I have not problem building and running this into a Mac however on Windows (Docker for windows) i can't run it and got this message:

: not found myworkdir/start: line 4: /myworkdir/start: line 6: syntax error: unexpected word (expecting "do")

If someone is familiar with this and know how to resolve it, please help !!

try to delete the character \r in the script start, for example: sed -i 's/\r//g' start Then copy the script start to windows and rebuild the image
