I've been learning about how ARM templates work and how there is an incremental mode. Can I perform a custom deployment that will update a resource with a template that only includes what I want to update?
What I'm trying to accomplish is to update or add rewrite rules for a specific set in our app gateway (see example below).
When I try the following I get InvalidTemplateDeployment errors with messages about missing template properties i.e. "0 IP configuration specified for gateway".
For my template I was trying to follow an example here https://learn.microsoft.com/en-us/azure/architecture/guide/azure-resource-manager/advanced-templates...
