Re: [HTCondor-users] Is it possible to set which classads are passed as env vars to docker?

[jcaballero.hep@xxxxxxxxx]

Hi Michael,

Not really.
I already have that wrapper script.
It receives from condor a given set of arguments, including some classads.
What I was asking is how to modify that list of classads being âsentâ to the wrapper script.

Cheers,
Jose
