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
