Folks, As I automate vmware infrastructure via ansible awx, I need to pass dynamic variables and datas in the playbook frequently. For example ESXi\_username and ESXi\_password, Datastore\_name etc. I had to fetch values for the dynamic variables from a .json file, I request your insights if any link for understanding this process or how should I use this kind of methodology Thanks, Best regds vijay ---

I am in a similar boat. I ended up using a series of set\_facts to dynamically shape the VMware variables depending on the requirements for a given machine. ---

it really depends how you want to do it. You can either use group vars, use dictionary structure or surveys in AWX.
