Greetings GEMPAK users,

I have published the latest Unidata GEMPAK 7.4.1 release as its own Docker
image, available at

https://hub.docker.com/r/unidata/gempak/

To Run Containerized GEMPAK (on any Docker-supported host machine):

1) docker pull unidata/gempak

2) docker run --user gempak -it unidata/gempak:latest

3) from within the container you have GEMPAK programs available in $PATH,
and an example script is supplied to show grid parameters from the latest
"A2NAM" grid (defined in $GEMTBL/config/datatype.tbl and
$GEMTBL/data-access/nam.xml to reference the 12km NAM domain), pulled from
the cloud-based AWIPS EDEX server

[gempak@1b075df3bed4 ~]$ ./rungempak.sh
 GDFILE   = A2NAM
 LSTALL   = YES
 OUTPUT   = T
 GDATTIM  = all
 GLEVEL   = 750
 GVCORD   = PRES
 GFUNC    = TMPK
