$(pwd) v $PWD

[codecowboy]

In the bind mount section, I had to use "$PWD" instead of "$(pwd)" but am unclear as to why.

I'm adapting the instructions to a current use case I have:

docker run -it --runtime=nvidia --gpus all --mount type=bind,source="$PWD"/upscale,target=/home name-of-container bash

The above works for me but if I use "$(pwd)" I get the error:

docker: Error response from daemon: invalid mount config for type "bind": bind source path does not exist: /upscale.
See 'docker run --help'.

Might this be the nvidia runtime causing this? I am using the nvidia container toolkit for the equivalent to passthrough in VM land.

The image is ubuntu:jammy

I wondered if you might be able to shed some light on this? I realise it's not strictly related to the course content.

edit - I since realised that this works:

docker run -it --runtime=nvidia --gpus all --mount type=bind,source="$(pwd)/upscale",target=/home name-of-container bash

So maybe there is a typo in your instructions (note that the closing quote goes after the complete path) or I have been staring at this for too long
