docker - entrypoint file not found

Question

I have a docker image with this command:

FROM ruby:2.4-alpine
WORKDIR /usr/src/app

COPY Gemfile /usr/src/app/Gemfile
COPY Gemfile.lock /usr/src/app/Gemfile.lock

RUN bundle config build.nokogiri --use-system-libraries
RUN bundle install --without development test

VOLUME /state

COPY . /usr/src/app/

ENTRYPOINT ["api-entrypoint.sh"]
CMD ["foreman", "start"]

it builds correctly but when I try to run bash, for example, I get this container_linux.go:247: starting container process caused "exec: "api-entrypoint.sh": executable file not found in $PATH" docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: "api-entrypoint.sh": executable file not found in $PATH".

I tried copy the entrypoint file, give it executable permissions as well with CMD...nothing worked

Answer 1

I had this problem with Docker for Windows and the solution was changing the entrypoint script file from CRLF -> LF.
