planned to have the patches attribute like the mentioned example

kustomize {
  patches {
	  target {
		  kind = "Deployment"
		  name = "the-deployment"
	  }
	  patch = <<-EOT
	        - op: replace
		  path: /spec/template/spec/containers/0/name
		  value: the-container-1
	  EOT
       }
 }

This block can be repeated in case multiple patches needed

I would also like this feature. Today found out the hard way that this is not supported.

  kustomize {
    patches = [

        target = {
          kind = "Deployment"
          name = "kong-mesh"
        }
        patch = <<-EOF ...
