Are there any known limitations that prevent NetCDF datasets from
being read using `/vsis3/`?
Yes. This requires Linux + sufficient permissions to run the userfaultfd
Linux system call, which can be an issue when running in a container. Cf
https://gdal.org/drivers/raster/netcdf.html#vsi-virtual-file-system-api-support.
The following works for me:
$ docker run --rm -it --security-opt seccomp=unconfined -e
CPL_AWS_CREDENTIALS_FILE=/path/to/.aws/credentials -v $HOME:$HOME
ghcr.io/osgeo/gdal:alpine-normal-3.8.1 gdalinfo
