vCenter Server Profile

 

vCenter Server Profile

What is a vCenter Profile? A vCenter Server Profile it is a tool introduced in 7.0 that creates a template from a known-good vCenter Server from which vCenter Server profiles may be created and applied.

The .json file can be copied to the target VCs, ensuring that they all inherit the same configuration settings, similar to a host profile for esxi hosts.

Step 1: Click on the home page of the vSphere Client and select Developer Center.

Step 2: Select your vCenter Server if necessary.

Step 3: On the top right, replace the word vcenter for appliance.

Step 4: Using the filtering capability, type profile to find infraprofile/configs.

Step 5: Expand infraprofile/configs and click on POST (in green) next to /api/appliance ...

Step 6: Click on Execute and Continue.

Step 7: Click on Download and save the resulting .json file in your favorite directory.
