Git Bash is an awesome shell that comes with Git for Windows but Docker and Docker Compose don't work well in it due to path conversions, see e.g. this issue. To confirm that you have the problem, try to run this:
$ docker run --rm -it ubuntu /bin/bash
If you get this error, you're impacted:
stat C:/Program Files/Git/usr/bin/bash: no such file or directory
Note how the Linux path is prepended with C:/Program Files/Git which is of course completely wrong from the container's point of view. Another common examples are volume mappings.
The key to a solution is the MSYS_NO_PATHCONV variable. Create two small scripts, docker and docker-compose, and put them in a location that has higher-priority than Docker's path. Actually, Docker puts itself very high in the list, you have to become no. 1 system path (not user PATH) to beat it. Here is an example from my computer:
The contents of the docker proxy script is this:
#!/bin/bash
(export MSYS_NO_PATHCONV=1; "docker.exe" "$@")Similarly for docker-compose.
One final important note is that you have to do this after every Docker update: it will simply put itself back at the top.
Hope this helps.
What extention did you use for your script? I tried using .SH and adding .SH to my PATHEXT, but it still prioritizes Docker.exe unless i type docker.sh
