Error Shell script fails on Docker for windows

Question

I’m 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" ]


#!/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 can't run it and get the following error:

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

I got a similar error, just 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.
