GATK WDL scripts on remote server without docker installation

Question

[AR]

Hi! Hope you all doing fine.

I want to use GATK pipeline (WDL workflows) for large number of samples on a remote server. Pardon me I am completely new to this field but what I can tell is the server I am working on I cannot use docker. So, my question is for using WDL do we need to have docker installed on remote server or can these WDLs be used without docker also? and how can we use these WDLs in python script as I am using python to submit my jobs on the remote server. I tried to search for it and found that most of the workflows are using docker. And GATK team suggests use of docker on remote server for parallelisation.

Any help would be highly appreciated! AR
