Describe the Problem

In testing METplus, George has found that running ncdump inside a MET Docker container often doesn't work. Instead it errors out. In testing, we have found that it's related to how the NetCDF, HDF4, and HDFEOS libraries are compiled. Recommend updating the Dockerfile to install HDF and HDFEOS into subdirectories of /usr/local and then ensure that ncdump still runs fine.

Once fixed, consider retagging MET version 9.1 so that ncdump is functional within that image.

Expected Behavior

The ncdump utility should run on all valid NetCDF files within the MET docker container.

Environment

Describe your runtime environment:
1. Machine: Docker Container
2. Software version number(s): images for version number met-9.1, develop, and likely others

To Reproduce

Describe the steps to reproduce the behavior:

docker pull dtcenter/met:9.1
docker create --name medium_range dtcenter/metplus-data:3.1-medium_range
docker run --rm -it --volumes-from medium_range dtcenter/met:9.1
ncdump -h /data/input/METplus_Data/model_applications/medium_range/grid_to_obs/netcdf/nam/conus_sfc/prepbufr.nam.20170601.t00z.tm00.nc
