Good afternoon,

Trying to run ncview via the docket container on windows 10 and I’m getting an error stating “can’t open display” and was wondering how one might get it to open properly. Thanks for the help!

Respectfully,

Andrew,

Ah yes, forwarding the display on a Windows 10 machine via a Docker
container is an issue.  We have another project in the DTC where we
provide
a tutorial of doing end-to-end Numerical Weather Prediction modelling
using
Docker containers (WRF, GSI, UPP, NCL, MET, and METviewer):

https://dtcenter.org/community-code/numerical-weather-prediction-nwp-
containers/tutorial-version-3

And having trouble forwarding the display has come up in that context
as
well.  Unfortunately, I don't have a good solution for you.  Some
Googling
reveals that there may be ways of solving this, but there's just no
general-purpose, foolproof way of doing so... at least that I'm aware
of.

Here's two workarounds...
(1) The tutorial instructions tell you to map a local drive from your
machine into the container:
   docker run --rm -it -v
${MET_TUTORIAL_DIR}/tutorial:/met/met-8.1/tutorial dtcenter/met:8.1
/bin/bash
That means that the output files you're generating should be
accessible on
your local machine in ${MET_TUTORIAL_DIR}/tutorial.
If there's some way of getting ncview on your Windows10 machine, you
could
run those commands there.  But I have no idea if that is possible.

(2) You could also run MET's plot_data_plane tool to visualize gridded
NetCDF output.  For example, on this page:
https://dtcenter.org/met-online-tutorial-metv8-0/grid-processing-
tools/pcp-combine/output
Run:
*plot_data_plane \*
*$MET_TUTORIAL_DATA/output/pcp_combine/sample_fcst_24L_2005080800V_12A.nc
\*
*$MET_TUTORIAL_DATA/output/pcp_combine/sample_fcst_24L_2005080800V_12A.ps
\*
*'name="APCP_12"; level="(*,*)";'*

And then via that PostScript file on your Windows10 machine instead.

John
