我的docker文件如下：

#Use python 3.6 image
FROM python:3.6
ENV PYTHONUNBUFFERED 1

#install required packages
RUN apt-get update
RUN apt-get install libsasl2-dev libldap2-dev libssl-dev python3-dev psmisc -y

#install a pip package
#Note: This pip package has a completely configured django project in it
RUN pip install <pip-package>

#Run a script
#Note: Here appmanage.py is a file inside the pip installed location(site-packages), but it will be accessible directly without cd to the folder
RUN appmanage.py appconfig appadd.json

#The <pip-packge> installed comes with a built in django package, so running it with following CMD
#Note: Here manage.py is present inside the pip package folder but it is accesible directly
CMD ["manage.py","runserver","0.0.0.0:8000"]

当我跑步时：

sudo docker build -t test-app .

dockerfile中的步骤，直到：RUN appmanage.py appconfig按预期成功运行，但是之后我得到了错误：

The command '/bin/sh -c appmanage.py appconfig ' returned a non-zero code: 137

当我用谷歌搜索错误时，我得到诸如内存不足的建议。但是我已经证实，系统（中心）有足够的内存。

附加信息

执行期间的命令行输出RUN appmanage.py appconfig为：

Step 7/8 : RUN appmanage.py appconfig
