title: entrypoint file not found
body: <p>I have a docker image with this command:</p>
  
  <pre><code>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"]
  </code></pre>
  
  <p>it builds correctly but when I try to run bash, for example, I get this
  <code>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".</code>  </p>
  
  <p>I tried copy the entrypoint file, give it executable permissions as well with <code>CMD</code>...nothing worked</p>
