Docker：运行pip安装boto成功，但从结果图像中丢失

我有这个Dockerfile：

FROM hopsoft/graphite-statsd MAINTAINER Jakub Holy # python dependencies RUN pip install --global-option="--without-libyaml" PyYAML RUN pip install boto RUN pip install cloudwatch-to-graphite==0.5.0 EXPOSE 80 2003 8125/udp CMD /sbin/my_init 

当我用docker build -t monitoring .构build它时docker build -t monitoring . 它似乎已经安装了boto，但在安装cloudwatch-to-graphite时，它的行为就好像它不在那里：

当我运行产生的容器时，没有boto或cloudwatch-to-graphite的痕迹 – 例如PyYAML在那里：

 root@7318ed2b04d0:/usr/local/src/carbon# pip list argparse (1.2.1) chardet (2.0.1) colorama (0.2.5) Django (1.3) django-tagging (0.3.1) docopt (0.6.2) flup (1.0.2) html5lib (0.999) Jinja2 (2.7.3) MarkupSafe (0.23) pip (1.5.4) python-memcached (1.53) PyYAML (3.11) requests (2.2.1) setuptools (3.3) six (1.5.2) Twisted (11.1.0) txAMQP (0.6.2) urllib3 (1.7.1) whisper (0.9.12) wsgiref (0.1.2) zope.interface (4.1.2) root@7318ed2b04d0:/usr/local/src/carbon# 

和：

  find / -iname '*boto*' | wc -l 0 

这里发生了什么？ 为什么不包含这些包？

如果我手动将它安装在容器中（ pip install cloudwatch-to-graphite ），它就在那里 – 尽pipe由于某种原因（从以前安装的石墨中剩下的），软件包最终会放在/opt/graphite/lib/python2.7/site-packages/ 。

PS：还有一个类似的问题： Pip install -e软件包不会出现在Docker中
