Docker:命令返回了非零代码:137

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

回答:

如前所述,该命令RUN appmanage.py appconfig appAdd.json按预期成功运行并报告System check

identified no issues (0 silenced).

此外,命令“坚持执行”杀死自己并返回退出代码137。此操作的最小更改是将您更新Dockerfile

...

#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

...

这只会强行忽略上一个命令的返回退出代码并继续构建。
