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
/usr/src/app may not be in your path so you should include the full path to the script. You also need to ensure that your entrypoint.sh is executable, docker will copy the permissions exactly as they are on your build host, so this step may not be needed depending on your scenario.
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/
RUN chmod 755 api-entrypoint.sh
ENTRYPOINT ["/usr/src/app/api-entrypoint.sh"]
CMD ["foreman", "start"]
I had the same problem - the entrypoint was not found, but I was sure that it was there.
It seems that you can't use single quotes ' for the entrypoint/command.
So I changed from
ENTRYPOINT ['/foo/bar/script.sh']
CMD ['run']
to
ENTRYPOINT ["/foo/bar/script.sh"]
CMD ["run"]
and it works.
I had this problem with Docker for Windows and the solution was changing the entrypoint script file from CRLF -> LF.
