我找到了一个 Django 项目，但未能通过以下方式在 Docker 容器中运行：

  1. git clone https://github.com/hotdogee/django-blast.git

  2. $ cat requirements.txt在此文件中，必须更新以下依赖项：

    • 海带==3.0.30
    • psycopg2==2.8.6

我有以下 Dockerfile：

FROM python:2
ENV PYTHONUNBUFFERED=1
WORKDIR /code
COPY requirements.txt /code/
RUN pip install -r requirements.txt
COPY . /code/

因为docker-compose.yml我使用：

version: "3"

services:
  db:
    image: postgres
    volumes:
      - ./data/db:/var/lib/postgresql/data
    environment:
      - POSTGRES_DB=postgres
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

docker-compose 使用哪个 IP 地址，因为我必须更改以下硬编码地址：

$ grep -ir "127.0.0.1" 
i5k/settings_prod.py:    'HOST': '127.0.0.1',
i5k/settings.py:    'HOST': '127.0.0.1',
i5k/settings.py:        'LOCATION': '127.0.0.1:11211',
Binary file i5k/settings.pyc matches
example/blastdb/AGLA_new_ids.faa.phd:13312790801051
grep: data/db: Permission denied
blast/static/blast/components/code-mirror/codemirror-4.0/mode/nginx/index.html:    fastcgi_pass   127.0.0.1:9000;
blast/static/blast/components/code-mirror/codemirror-4.0/mode/nginx/index.html:    fastcgi_pass 127.0.0.1:9000;
axes/tests.py:        reset(ip='127.0.0.1')
axes/decorators.py:            ip_address = '127.0.0.1'

先感谢您

我找到了一个 Django 项目，但未能通过以下方式在 Docker 容器中运行：

  1. git clone https://github.com/hotdogee/django-blast.git

  2. $ cat requirements.txt

    #psycopg2==2.6.0 # 如果使用 postgreSQL 作为数据库后端

我有以下 Dockerfile：

FROM python:2.7

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
        postgresql-client \
    && rm -rf /var/lib/apt/lists/*

WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install -r requirements.txt
COPY . .

EXPOSE 8000
CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]

接下来，我跑了：

$ docker run --name some-django-app -p 8000:8000 -d my-django-app
4202d7b2b47603e32dc800d3fbedbfaf4363f8cafe45684242aa3bb2b0eba257

最后，我输入http://localhost:8000/并得到了Firefox can’t establish a connection to the server at localhost:8000.

我使用了以下命令，但由于某些原因，它找不到参数。

$ ls lachesis.ini 
lachesis.ini
$ docker run -it 5071f1ab27a0 /usr/local/bin/Lachesis lachesis.ini
RunParams is parsing INI file at lachesis.ini
ERROR: Can't find file lachesis.ini
