Docker：命令返回了非零代码：137

Question

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中直到RUN appmanage.py appconfig 的步骤均按预期成功运行，但此后我得到错误：

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

当我用Google搜索错误时，我得到诸如内存之类的建议是不够​​的。但是我已经证实，系统（centos）有足够的内存。

其他信息

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

Step 7/8 : RUN appmanage.py appconfig

Answer 1

如前所述，命令RUN appmanage.py appconfig appAdd.json按预期成功运行，并报告了System check identified no issues (0 silenced).。

此外，该命令“杀死”自己并返回退出代码137。此操作的最小更改是将Dockerfile更新为

...
#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 || true
...

这只会强制忽略上一条命令的返回退出代码并继续构建。
