[英]Run command on entrypoint in docker outputs no file errors
On a simple dockerfile: 在简单的dockerfile上:
FROM python:3
ENV PYTHONUNBUFFERED 1
WORKDIR /code/
If I run: 如果我运行:
docker build -t my_image .
docker run -v ~/Downloads/data/:/home -it -d my_image # mount data folder inside home
docker exec -it container_id sh -c "python script.py -i /home/db.sqlite"
Everything runs ok. 一切正常。 But I would like to run the script.py
on run so that there is no need for an exec command. 但是我想在运行时运行script.py
,因此不需要exec命令。
So I added to the dockerfile: 所以我添加到dockerfile中:
ENTRYPOINT ["python script.py -i /home/db.sqlite"]
But when I run my container now it fails with a file or folder not found error at python script.py
但是当我现在运行容器时,它失败,并在python script.py
出现文件或文件夹未找到错误
I think the problem is how the ENTRYPOINT
syntax works. 我认为问题在于ENTRYPOINT
语法如何工作。 Your using the exec-form and it does not find the binary (it uses the whole command line as path to the binary). 您使用的是exec-form,但找不到二进制文件(它使用整个命令行作为二进制文件的路径)。
From https://docs.docker.com/engine/reference/builder/#entrypoint : 从https://docs.docker.com/engine/reference/builder/#entrypoint :
ENTRYPOINT has two forms: ENTRYPOINT有两种形式:
ENTRYPOINT ["executable", "param1", "param2"] (exec form, preferred) ENTRYPOINT [“ executable”,“ param1”,“ param2”](执行表格,首选)
ENTRYPOINT command param1 param2 (shell form) ENTRYPOINT命令param1 param2(shell形式)
So try either: 因此,请尝试:
ENTRYPOINT ["/path/to/python", "script.py", "-i", "/home/db.sqlite"]
Or 要么
ENTRYPOINT python script.py -i /home/db.sqlite
