You should see an output like this: ```bash mydomain.gent01.dev.grid.tf ``` ## Gateway FQDN In case you have a FQDN already pointing to the node, you can expose your VM using Gateway FQDN. ## Example ```go import ( "fmt" "github.com/threefoldtech/tfgrid-sdk-go/grid-client/deployer" "github.com/threefoldtech/tfgrid-sdk-go/grid-client/workloads" "github.com/threefoldtech/zos/pkg/gridtypes/zos" ) func main() { // Create Threefold plugin client tfPluginClient, err := deployer.NewTFPluginClient(mnemonics, "sr25519", network, "", "", "", 0, true) // Create gateway to deploy gateway := workloads.GatewayFQDNProxy{ NodeID: 14, Name: "mydomain", Backends: []zos.Backend{"http://[300:e9c4:9048:57cf:6d98:42c6:a7bf:2e3f]:8080"}, FQDN: "my.domain.com", TLSPassthrough: true, } err = tfPluginClient.GatewayFQDNDeployer.Deploy(ctx, &gateway) gatewayObj, err := tfPluginClient.State.LoadGatewayFQDNFromGrid(nodeID, gateway.Name, gateway.Name) } ``` This deploys a Gateway FQDN Proxy that forwards requests to from node 14 public IP to your VM.
