Find out what instance the job with powershell step is running on.


We have multiple environments with different instance names.  Currently I use this command to define the connection to the instace:


So the instance name is hard coded.  

I am running the script as a job step and need this job to work in all environments without updating the job code.

How do I find out the server and the instance name with powershell on which the SQL job is running?
