The container created by docker-compose does not see the entrypoint

问题

I encountered a problem in docker-compose that the api service doesn't see the entrypoint.sh and crashes. Specific error:
> exec /app/entrypoint.sh: no such file or directory

Dockerfile:

  1. FROM ruby:3.1.0-slim
  3. ENV LANG=C.UTF-8
  4. WORKDIR app
  5. RUN apt-get update && apt-get -y install build-essential libpq-dev autoconf autogen libtool
  6. EXPOSE 3000
  8. COPY Gemfile /app/Gemfile
  9. COPY Gemfile.lock /app/Gemfile.lock
  11. RUN bundle install
  13. COPY ./entrypoint.sh .
  15. ENTRYPOINT ["/app/entrypoint.sh"]

.docker-compose.yml:

  1. services:
  2.   es:
  3.     image: elasticsearch:8.7.0
  4.     environment:
  5.       - discovery.type=single-node
  6.       - ES_JAVA_OPTS=-Xms750m -Xmx750m
  7.       - xpack.security.enabled=false
  9.   db:
  10.     image: postgres:14.0-alpine
  11.     environment:
  12.       - POSTGRES_PASSWORD= ...
  13.     ports:
  14.       - 5431:5432
  16.   redis:
  17.     image: redis:7.0.11-alpine
  19.   api:
  20.     build: .
  21.     volumes:
  22.       - .:/app
  23.     ports:
  24.       - 3000:3000
  25.     environment:
  26.       - ELASTICSEARCH_URL=http://es:9200
  27.       - REDIS_URL=redis://redis:6379
  28.     command: bundle exec rails s -p 3000 -b '0.0.0.0'
  29.     depends_on:
  30.       - db
  31.       - redis

The file structure of the container created for the api service:
Docker-compose创建的容器无法看到入口点。

Also, strangely enough, the dockerfile has not changed since it was successfully started. I can't figure out where the problem is. Help me, please Docker-compose创建的容器无法看到入口点。

I tried deleting all images, all containers, and all volumes, none of this helped.

The executable in shebang of entrypoint.sh is not found inside docker container. Install the executable or change shabang. Most probably you have bash and bash is not inside the container, for example.
