Devcontainer will not work on machines without GPU

[adverley]

Our devcontainer uses the nvidia-container-runtime which specifies the --gpus docker run parameter. This only works on machines containing an NVIDIA GPU.

Possible solutions:

1. [Lazy and easy] Comment out the --gpus all line
2. Follow-up feature request for dynamic docker runargs
3. Check available variables in devcontainer. Maybe we can set --gpus to a variable that just ignores this param. Don't think this will work though.

Exactly the same problem here. We have two devcontainer files (devcontainer.json with gpu support, and devcontainer-nogpu.json) the its up to the poor dev running on a Mac (me) to have to swap them out constantly.
