GLB Service

GLB Service example

The following template example shows how to set up a GLB service and it's dependencies. There is a DNS zone file, DNS zone configuration, a GLB monitor, two locations and a GLB service.

resource "brocadevtm_dns_zone_file" "example" {
name = "example.com.db"
  dns_zone_config = <<DNS_ZONE_FILE

                                        3600; refresh after 1 hour
                                        300; retry after 5 minutes
