The Jinja2 python module is not availed in the shell environment that the Gaea Node is configured to:

Thanks Terry! Will check with Kris and will sort out jinja2 configuration issue.

Thanks Terry! Will check with Kris and will sort out jinja2 configuration issue.

@TerrenceMcGuinness-NOAA, is it expected that the py-jinja2 module be loaded into the Jenkins runner? This seems like something that the shell environment here should load at runtime.

[TerrenceMcGuinness-NOAA]

@kbooker79 It is required that the shell that the Jenkins Node is connected to be configured with all the modules specified in ${HOMEgfs}/modulefiles/module_gwsetup.${MACHINE_ID}.lua for Global-Workflow. This is done on the EMC Nodes (here) in the shell that launches the Java Agent to Jenkins. Which would be similar to Method 2 outlined (here)

@TerrenceMcGuinness-NOAA, can we try using method 1, and just have Jenkins set the environment variable MODULE_GWSETUP_PATH=$HOMEgfs/modulefiles, then load the module path and module for the node module_gwsetup.gaea at runtime? My only issue with method 2 is that it sets certain module persistently in a shell environment that is shared by other teams. I hope this makes sense.

[AnilKumar-NOAA]

@TerrenceMcGuinness-NOAA Please re-run the PR again. Thanks

@TerrenceMcGuinness-NOAA @AnilKumar-NOAA, I've reconfigured Gaea to use Method2 instead, if $HOMEgfs (and subsequently MODULE_GWSETUP_PATH should be) it is set properly this should work now. Please re-run this workflow on Gaea and let me know if you have questions.

It still doesn't appear the shell running on Gaea is getting the gwsetup module loaded:

as such:

Terry.McGuinness@gaea54:~/NOAA/global-workflow/modulefiles> module purge
Terry.McGuinness@gaea54:~/NOAA/global-workflow/modulefiles> module use $PWD
Terry.McGuinness@gaea54:~/NOAA/global-workflow/modulefiles> module load module_gwsetup.gaea 
Terry.McGuinness@gaea54:~/NOAA/global-workflow/modulefiles> python -c "import jinja2"

@TerrenceMcGuinness-NOAA It looks like you are using module purge on Gaea which may lead to issues (from the Gaea docs): "Do not use the command module purge on Gaea. This will remove all modules currently loaded by default in your environment and may lead to errors, and can make your session unusable. If you do run the command to purge your module environment, log out and back in to Gaea to restore the default environment with the default modules loaded."

module-setup.sh is using module reset instead of module purge, which is our preferred method anyway.

[AnilKumar-NOAA]

For CI test - We have updated module setup for Gaea. Some issue with old module path and need to be updated to fix all environments for gaea system

[WalterKolczynski-NOAA]

Where does this one stand? Does it need the Gaea CI Ready label reapplied? Should it be closed?

[AnilKumar-NOAA]

we are still working on it. It's just on hold because gaea c5 has some OS upgrades with spack stack changes. We submitted all the PR's related to all these changes. Soon these PR's will be merged and we will start working on CI test after that.

[WalterKolczynski-NOAA]

Marked this as draft since it is just a dummy PR.
