## Introduction
After [deploying a VM](grid3_go_vm.md) you can deploy Gateways to further expose your VM.
2024-04-29 17:49:02 +00:00
## Gateway Name
This generates a FQDN for your VM.
## 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/tfgrid-sdk-go/grid-proxy/pkg/types"
"github.com/threefoldtech/zos/pkg/gridtypes/zos"
)
func main() {
// Create Threefold plugin client
tfPluginClient, err := deployer.NewTFPluginClient(mnemonics, "sr25519", network, "", "", true, false)
// Get a free node to deploy
domain := true
status := "up"
filter := types.NodeFilter{
Domain: &domain,
Status: &status,
}
nodeIDs, err := deployer.FilterNodes(tfPluginClient.GridProxyClient, filter)
nodeID := uint32(nodeIDs[0].NodeID)
// Create gateway to deploy
gateway := workloads.GatewayNameProxy{
NodeID: nodeID,
Name: "mydomain",
Backends: []zos.Backend{"http://[300:e9c4:9048:57cf:6d98:42c6:a7bf:2e3f]:8080"},
TLSPassthrough: true,
}
err = tfPluginClient.GatewayNameDeployer.Deploy(ctx, &gateway)
gatewayObj, err := tfPluginClient.State.LoadGatewayNameFromGrid(nodeID, gateway.Name, gateway.Name)
fmt.Println(gatewayObj.FQDN)
}
```
This deploys a Gateway Name Proxy that forwards requests to your VM. 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.
