Docker在circleCI上失败用于Rails测试，在本地工作，在CircleCI上构建时出现此错误

问题描述

因此，并不是所有人都对docker-compose有所了解，但是我正在尝试将CircleCI与我已经在本地使用Docker-Compose进行了Docker化的项目集成。但是当在CircleCI上运行相同的构建时，我似乎会遇到这些错误。

错误是：

Creating project_app_1      ... error
ERROR: for project_app_1  Cannot start service app: oci runtime error: container_linux.go:265: starting container process caused "exec: \"./entrypoints/docker-entrypoint.sh\": stat ./entrypoints/docker-entrypoint.sh: no such file or directory"
ERROR: for app  Cannot start service app: oci runtime error: container_linux.go:265: starting container process caused "exec: \"./entrypoints/docker-entrypoint.sh\": stat ./entrypoints/docker-entrypoint.sh: no such file or directory"
ERROR: Encountered errors while bringing up the project.
Exited with code exit status 1
CircleCI received exit code 1

作为参考，我的circleCI的 config.yml 文件是：

version: 2.1
orbs:
  ruby: circleci/ruby@0.1.2

jobs:
  build:
    docker:
      - image: circleci/cci-demo-docker-primary:0.0.2
    steps:
      - checkout
      
      - setup_remote_docker
      - run:
          name: Install Docker Compose
          command: |
            set -x
            curl -L https://github.com/docker/compose/releases/download/1.25.3/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
            chmod +x /usr/local/bin/docker-compose
      
      - run:
          name: Set working directory
          command: |
            cd ./
            chmod +x ./entrypoints/docker-entrypoint.sh
      - run:
          name: Running Compose to start container in test environment
          command: |
            docker-compose -f testenv.docker-compose.yml up -d
      - run:
          name:  Setup test database and migrations
          command: |
            docker-compose exec app bundle exec rake db:setup db:migrate
      - run:
          name: Running tests
          command: |
            docker-compose exec rails test 

我的 testenv.docker-compose.yml 文件如下：

version: '3.4'

services:
  app: 
    build:
      context: .
      dockerfile: Dockerfile
    depends_on:     
      - database
    ports: 
      - "3000:3000"
    volumes:
      - .:/app
      - gem_cache:/usr/local/bundle/gems
      - node_modules:/app/node_modules
    environment:
      RAILS_ENV: test
      DATABASE_NAME: proj_mgmt
      DATABASE_USER: postgres
      DATABASE_PASSWORD: postgres
      DATABASE_HOST: database

  database:
    image: postgres:12.1
    volumes:
      - db_data:/var/lib/postgresql/data
      - ./init.sql:/docker-entrypoint-initdb.d/init.sql

volumes:
  gem_cache:
  db_data:
  node_modules:

最后，我的 Dockerfile 是：

FROM ruby:2.7.0

ENV BUNDLER_VERSION=2.1.4

RUN curl -sL https://deb.nodesource.com/setup_10.x | bash - \
    && apt install -y nodejs

RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - \
    && echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list \
    && apt-get update \
    && apt-get install yarn   

RUN gem install bundler:2.1.4

WORKDIR /app

COPY Gemfile Gemfile.lock ./

RUN bundle config build.nokogiri --use-system-libraries

RUN bundle check || bundle install

COPY package.json yarn.lock ./

RUN yarn install --check-files

COPY . ./ 

RUN chmod +x ./entrypoints/docker-entrypoint.sh

ENTRYPOINT ["./entrypoints/docker-entrypoint.sh"]

在此错误的基本google搜索中，我被重定向到here，这表明我添加了 chmod +x docker-entrypoint.sh 到我的 Dockerfile 。 但这也无济于事，并且相同的错误仍然存​​在。相同的 testenv.docker-compose.yml 可以在我的本地计算机上完美运行，而且我似乎无法弄清楚出了什么问题。任何帮助表示赞赏。
