构建Django的Web镜像

文章目录

- 构建Django的Web镜像

1.前提

已经在环境上安装了Docker

2.步骤

1.拉取最新代码

bash 复制代码

git clone https://github.com/lp1506947671/recruitment.git

2.指定manage.py中读取的Django配置文件来源为os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings.local")

python 复制代码

#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys


def main():
    """Run administrative tasks."""
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings.local")
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == "__main__":
    main()

3.从拉取的代码中找到Dockerfile文件

dockerfile 复制代码

FROM python:3.10-alpine
MAINTAINER xiaopawnye
ENV DJANGO_SETTINGS_MODULE=settings.local
WORKDIR /data/recruitment
COPY ./requirements.txt .
COPY ./start.sh .
COPY ./src .
RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories # 替换为apk阿里云镜像
RUN apk add --update --no-cache curl jq py3-configobj py3-pip py3-setuptools python3-dev \
  && apk add --no-cache gcc g++ jpeg-dev zlib-dev libc-dev libressl-dev musl-dev libffi-dev \
  && python -m pip install --upgrade pip \
  && pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple \
  && apk del gcc g++ libressl-dev musl-dev libffi-dev python3-dev \
  && apk del curl jq py3-configobj py3-pip py3-setuptools \
  && ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
  && echo 'Asia/Shanghai' >/etc/timezone  \
  && rm -rf /var/cache/apk/*
RUN sed -i 's/\r//' /data/recruitment/start.sh
RUN chmod +x ./start.sh
EXPOSE 39979
CMD ["/bin/sh", "/data/recruitment/start.sh"]

4.构建镜像,注意下面命令中recruitment/必须是Dockerfile文件的上级父目录
bash 复制代码
```
docker build --network=host -t xiaopawnye/recruitment-base:v1 recruitment/
```

5.镜像构建完成后启动容器,命令如下

bash 复制代码

docker run --rm --network=host  -p 39979:39979 -v "$(pwd)":/data/recruitment  --env server_params="--settings=settings.local" xiaopawnye/recruitment-base:v1

3.问题与思考

问题1:执行镜像构建命令时报错docker build -t xiaopawnye/recruitment-base:v1

bash 复制代码

报错ERROR: unable to select packages:

  curl (no such package):

    required by: world[curl]

  jq (no such package):

    required by: world[jq]

  py3-configobj (no such package):

    required by: world[py3-configobj]

  py3-pip (no such package):

    required by: world[py3-pip]

  py3-setuptools (no such package):

    required by: world[py3-setuptools]

  python3 (no such package):

    required by: world[python3]

  python3-dev (no such package):

    required by: world[python3-dev]

解决方法:

查询google,Dockerfile编译django时执行pip命令报错网络不通,通过将命令修改为docker build --network=host -t xiaopawnye/recruitment-base:v1即可

问题2报错

bash 复制代码

问题3:容器启动成功但是web无法访问,显示违反csrf,解决方法注释如下代码
python 复制代码
```
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True
```
