Question

运行 docker-compose up –build 时，我总是遇到此错误消息。任何人都知道我对 docker-entrypoint 文件做错了什么？

 ERROR: for 986991ccdfe1_ubercoach_web_1  Cannot start service web: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"./docker-entrypoint.sh\": permission denied": unknown

ERROR: for web  Cannot start service web: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"./docker-entrypoint.sh\": permission denied": unknown
ERROR: Encountered errors while bringing up the project.

从 python:3 中拉取基础镜像

ENV PYTHONUNBUFFERED 1

# Set work directory
RUN mkdir /code
WORKDIR /code

# Install dependencies
RUN pip install --upgrade pip
RUN pip install pipenv
COPY ./Pipfile /code/Pipfile
RUN pipenv install --deploy --system --skip-lock --dev

# Copy project
COPY . /code/

# Collect static files
echo "Collect static files"
python manage.py collectstatic --noinput

# Apply database migrations
echo "Apply database migrations"
python manage.py migrate

# Start server

Answer 1

\”./docker-entrypoint.sh\”: 权限被拒绝”: 未知

我猜你的 docker-entrypoint.sh 没有执行权限（ x ）。而且 docker-compose.yml 并不是 docker-entrypoint.sh 的最佳位置。这是覆盖设置，请参见 entrypoint 。默认值应该放在 Dockerfile 中。尝试这个：

将此添加到您的末尾 Dockerfile

 COPY ./docker-entrypoint.sh /docker-entrypoint.sh
RUN chmod +x /docker-entrypoint.sh
ENTRYPOINT ["/docker-entrypoint.sh"]

docker-entrypoint.sh 应该与 Dockerfile 位于同一文件夹中（或调整 COPY 路径）。从 --- 中删除 entrypoint docker-compose.yml 。重建，重新运行。

你应该像这样复制入口点：

 version: '3'

services:
  db:
    image: postgres
    ports:
      - "5432:5432"
  web:

    entrypoint: /docker-entrypoint.sh
    env_file: .env
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

Dockerfile：

 # Pull base image FROM python:3

# Set environment varibles
ENV PYTHONUNBUFFERED 1

# Set work directory
RUN mkdir /code
WORKDIR /code

# Install dependencies
COPY ./docker-entrypoint.sh /docker-entrypoint.sh
RUN chmod +x /docker-entrypoint.sh

RUN pip install --upgrade pip
RUN pip install pipenv
COPY ./Pipfile /code/Pipfile
RUN pipenv install --deploy --system --skip-lock --dev

# Copy project
COPY . /code/
