Docker：“未知指令：VIRTUALENV”(Docker: "Unknown instruction: VIRTUALENV')

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：

应该删除那些容器吗？ 为什么不看到virtualenv ？

is it supposed to remove those containers? Why isn't it seeing virtualenv?

最满意答案

应该删除那些容器吗？

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

为什么不看到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“VIRTUALENV”指令。 据推测，您打算在ADD之后的每一行之前放置RUN ：

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

is it supposed to remove those containers?

Yes. If you want to keep them for some reason, pass --rm=false to the docker build command.

Why isn't it seeing virtualenv?

It is seeing it, but because it's at the start of a line, it treats it like a Dockerfile instruction, but there is no "VIRTUALENV" instruction. Presumably, you meant to put RUN before each line after the 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
