Running docker commands in bash script leads to segmentation fault

Question

The commands are like:

docker run / stop / rm ...

which works in terminal while causes segmentation fault in bash script.

I compared the environments between bash script and terminal, as shown below.

You've rewritten the docker command in a shell, it's entirely possible this is even a recursive definition. Remove this from your environment:

docker () 
{ 
    docker run -dti -v ${PWD}:/home --restart always -p 50000:50000 --name projDev owen263/python3-uwsgi-alpine-docker sh
}
