Почему создание из файла докеров занимает все пространство на диске?

Question

Я использую docker-compose для создания и запуска приложения.

здесь докер-compose.yml:

db: 
    image: postgres 
web: 
    build: . 
    command: sh startup.sh 
    volumes: 
    - .:/code 
    ports: 
    - "8000:8000" 
    links: 
    - db 

мой Dockerfile:

FROM python:2.7 
ENV PYTHONUNBUFFERED 1 
RUN apt-get update && apt-get install -y nginx 
RUN mkdir /code 
WORKDIR /code 
ADD requirements.txt /code/ 
RUN pip install -r requirements.txt 
ADD . /code/ 

Так что, когда я иду в командную строку и сделать docker-compose up это только вид остается там говорят Building web... в течение долгого времени, наконец, заканчивается ошибкой, говоря, что у нее закончилось свободное пространство. Бродячий vm имеет 40 Гб, поэтому я не уверен, что приведет к тому, что все это пространство будет рассмотрено.

Кто-нибудь знает, что сначала принимает Building web... шаг так долго? Или почему это займет все пространство на машине. Я только устанавливаю несколько пакетов и библиотек pip.

Answer 1

Вы писали: mkdir xxx ; cd xxx Перед созданием файла Dockerfile?

Возможно, у вас появилось сообщение «контекст загрузки».

Извлечение из https://github.com/docker/docker/issues/2342 «клиент tar/сжатие каталога (и всех подкаталогов), в котором вы выполнили сборку докеров. Да, это правильно. Если вы выполните это в корневом каталоге, весь ваш диск получит tar'd и отправлен на демон докеров ».
