Question

Dockerfile ：

FROM ubuntu:14.04.2

RUN apt-get -y update && apt-get upgrade -y
RUN apt-get install python build-essential python-dev python-pip python-setuptools -y
RUN apt-get install libxml2-dev libxslt1-dev python-dev -y
RUN apt-get install libpq-dev postgresql-common postgresql-client -y
RUN apt-get install openssl openssl-blacklist openssl-blacklist-extra -y
RUN apt-get install nginx -y
RUN pip install virtualenv uwsgi

ADD canonicaliser_api ~
virtualenv ~/canonicaliser_api/venv
source ~/canonicaliser_api/venv/bin/activate
pip install -r ~/canonicaliser_api/requirements.txt

RUN echo "daemon off;" >> /etc/nginx/nginx.conf
EXPOSE 80

CMD service nginx start

构建错误：

...

Step 9 : VIRTUALENV 
Unknown instruction: VIRTUALENV

它应该删除那些容器吗？为什么看不到virtualenv？

Answer 1

它应该删除那些容器吗？

是。如果由于某种原因想要保留它们，请将--rm=false传递给docker build命令。

为什么它没有看到virtualenv？

它正在看到它，但因为它在一行的开头，它将它视为Dockerfile指令，但没有＆＃34; VIRTUALENV＆＃34;指令。据推测，您打算在RUN之后的每一行之前放置ADD：

ADD canonicaliser_api ~
RUN virtualenv ~/canonicaliser_api/venv

# This one needs to be a single RUN so the "source" will affect pip.
RUN source ~/canonicaliser_api/venv/bin/activate && \
        pip install -r ~/canonicaliser_api/requirements.txt

Docker：“未知指令：VIRTUALENV”
