Mover uma instância de VM entre zonas ou regiões

Mantenha tudo organizado com as coleções Salve e categorize o conteúdo com base nas suas preferências.

gcloud

Neste exemplo, você move uma VM chamada myinstance que tem dois discos permanentes chamados mybootdisk e mydatadisk , de europe-west1-c para us-west1-b .

1. Identifique os discos associados à VM que você deseja mover:

   gcloud compute instances describe myinstance --format="list(name,status,disks)"
   

   Neste exemplo, você encontra os dois discos associados a seguir para a VM myinstance :

   • Um disco de inicialização chamado mybootdisk
   • Um disco de dados chamado mydatadisk

2. Defina o estado de exclusão automática de mybootdisk e mydatadisk como false para garantir que os discos não sejam excluídos automaticamente quando a VM for excluída.

   gcloud compute instances set-disk-auto-delete myinstance --zone europe-west1-c \
       --disk mybootdisk --no-auto-delete

   Se o estado foi atualizado, gcloud compute retornará a resposta Updated [...] . Se o estado de exclusão automática já estiver definido como falso, gcloud compute retornará:

   No change requested; skipping update for [myinstance].

3. (Opcional) Salve os metadados da VM.

   Quando você exclui sua VM, os metadados da VM também são removidos. Você pode salvar essas informações em um arquivo separado e reaplicar os metadados da VM à nova VM.

   Descreva os metadados da sua VM da seguinte forma:

   gcloud compute instances describe myinstance --zone europe-west1-c

   Salve o conteúdo em um arquivo separado.

4. Crie backups dos seus dados usando snapshots de discos permanentes.

   Como precaução, crie backups dos seus dados enquanto os discos permanentes ainda estão anexados à VM usando snapshots de discos permanentes. Antes de criar um snapshot, certifique-se de que ele seja consistente com o estado do disco permanente seguindo as práticas recomendadas para snapshots .

   Depois de limpar os buffers de disco, crie os snapshots:

   gcloud compute disks snapshot mybootdisk mydatadisk \
       --snapshot-names backup-mybootsnapshot,backup-mydatasnapshot \
       --zone europe-west1-c 

   Para verificar se o snapshot foi criado, execute gcloud compute snapshots list .

5. (Opcional) Se você estiver movendo uma VM entre zonas dentro da mesma região e quiser preservar seu endereço IP interno ou externo efêmero, promova o endereço IP interno ou externo para um endereço IP estático, que poderá ser reutilizado posteriormente.

6. Exclua sua VM.

   Excluir sua VM a desliga de forma limpa e desanexa todos os discos permanentes.

   gcloud compute instances delete myinstance --zone europe-west1-c

   gcloud solicita que você confirme a exclusão:

   
   The following VMs are deleted. Any attached disks configured to
   be auto-deleted are deleted unless they are attached to any other
   VMs or the `--keep-disks` flag is given and specifies them for keeping.
   Deleting a disk is irreversible and any data on the disk is lost.
   — [myinstance] in [europe-west1-c]
   Do you want to continue (Y/n)?

   Como você desativou o estado de exclusão automática dos discos anteriormente neste processo, insira Y para continuar e ignore o aviso.

7. Em seguida, crie outro instantâneo do disco de inicialização e do disco de dados.

   gcloud compute disks snapshot mybootdisk mydatadisk \
       --snapshot-names mybootsnapshot,mydatasnapshot \
       --zone europe-west1-c 

   Created [.../mydatasnapshot].
   Created [.../mybootsnapshot].

8. (Opcional) Exclua seus discos permanentes.

   Se você planeja reutilizar os nomes dos discos permanentes para os novos discos, deverá excluir os discos existentes para liberar os nomes. Excluir seus discos também economiza custos de armazenamento em disco persistente.

   Se você não planeja reutilizar os mesmos nomes de disco, não será necessário excluí-los.

   gcloud compute disks delete mybootdisk mydatadisk --zone europe-west1-c

9. Crie novos discos permanentes em us-west1-b com base nos snapshots que você criou. Primeiro crie o disco de inicialização.

   gcloud compute disks create mybootdiskb --source-snapshot mybootsnapshot \
       --zone us-west1-b

   Created [.../mybootdiskb].
   NAME        ZONE           SIZE_GB TYPE        STATUS
   mybootdiskb us-west1-b     100     pd-standard READY

   Em seguida, crie o disco de dados.

   gcloud compute disks create mydatadiskb --source-snapshot mydatasnapshot \
       --zone us-west1-b

   Created [.../mydatadiskb].
   NAME        ZONE           SIZE_GB TYPE        STATUS
   mydatadiskb us-west1-b 4000    pd-standard READY

10. Recrie sua VM em us-west1-b .

    • Se você optou por salvar os metadados da VM em um arquivo, por exemplo myinstance.describe , poderá usá-lo para definir os mesmos metadados na sua VM.

    • Se sua VM tiver um endereço IP externo estático, você poderá reatribuir esse endereço à sua nova VM especificando a opção --address [ADDRESS] . Se você estiver movendo uma VM entre regiões, deverá escolher um endereço IP externo diferente para a nova instância de VM.

    • Se sua VM tiver um endereço IP interno estático, você poderá reatribuir esse endereço à sua nova VM especificando a opção --private-network-ip ADDRESS . Se você estiver movendo uma VM entre regiões, deverá escolher um endereço IP interno diferente para a nova instância de VM.

    • Se sua VM incluiu GPUs, adicione GPUs à VM usando a opção --accelerator .

    • Se a VM usar uma sub-rede específica, adicione o sinalizador --subnet [SUBNET_NAME] .

    Para obter uma lista completa de sinalizações adicionais, consulte gcloud computing instances create .

    gcloud compute instances create myinstanceb --machine-type n1-standard-4 \
        --zone us-west1-b \
        --disk name=mybootdiskb,boot=yes,mode=rw \
        --disk name=mydatadiskb,mode=rw 

    Created [.../myinstanceb].
    NAME        ZONE           MACHINE_TYPE  INTERNAL_IP    EXTERNAL_IP     STATUS
    myinstanceb us-west1-b     n1-standard-4 10.240.173.229 146.148.112.106 RUNNING

11. (Opcional) Exclua os snapshots do disco permanente.

    Depois de confirmar que suas máquinas virtuais foram movidas, economize nos custos de armazenamento excluindo os instantâneos temporários que você criou.

    gcloud compute snapshots delete mybootsnapshot mydatasnapshot

    Se você não precisar mais dos seus snapshots de backup, exclua-os também:

    gcloud compute snapshots delete backup-mybootsnapshot backup-mydatasnapshot

1. Obtenha os detalhes da VM e identifique os discos anexados à VM.

   import (
   	"context"
   	"fmt"
   	"io"
   
   	compute "cloud.google.com/go/compute/apiv1"
   	computepb "cloud.google.com/go/compute/apiv1/computepb"
   )
   
   // getInstance prints a name of a VM instance in the given zone in the specified project.
   func getInstance(w io.Writer, projectID, zone, instanceName string) error {
   	// projectID := "your_project_id"

   	}
   
   	fmt.Fprintf(w, "Instance: %s\n", instance.GetName())
   
   	return nil
   }
   

2. Defina o estado de exclusão automática do disco de inicialização e do disco de dados como false para garantir que os discos não sejam excluídos automaticamente quando a VM for excluída.

   import (

   	// autoDelete := true
   
   	ctx := context.Background()
   	instancesClient, err := compute.NewInstancesRESTClient(ctx)
   	if err != nil {
   		return fmt.Errorf("NewInstancesRESTClient: %w", err)
   	}
   	defer instancesClient.Close()
   
   	getInstanceReq := &computepb.GetInstanceRequest{
   		Project:  projectID,

   	diskExists := false
   
   	for _, disk := range instance.GetDisks() {
   		if disk.GetDeviceName() == diskName {
   			diskExists = true
   			break
   		}
   	}
   
   	if !diskExists {
   		return fmt.Errorf(
   			"instance %s doesn't have a disk named %s attached",
   			instanceName,
   			diskName,
   		)
   	}
   
   	req := &computepb.SetDiskAutoDeleteInstanceRequest{
   		Project:    projectID,

   	if err = op.Wait(ctx); err != nil {
   		return fmt.Errorf("unable to wait for the operation: %w", err)
   	}
   
   	fmt.Fprintf(w, "disk autoDelete field updated.\n")
   
   	return nil
   }
   

3. Crie backups dos seus dados usando snapshots de discos permanentes.

   Como precaução, crie backups dos seus dados enquanto os discos permanentes ainda estão anexados à VM usando snapshots de discos persistentes. Antes de criar um snapshot, certifique-se de que ele seja consistente com o estado do disco permanente seguindo as práticas recomendadas para snapshots .

   Depois de limpar os buffers de disco, crie os snapshots:

   import (
   	"context"
   	"fmt"
   	"io"
   
   	compute "cloud.google.com/go/compute/apiv1"
   	computepb "cloud.google.com/go/compute/apiv1/computepb"
   	"google.golang.org/protobuf/proto"
   )
   
   // createSnapshot creates a snapshot of a disk.
   func createSnapshot(
   	w io.Writer,
   	projectID, diskName, snapshotName, zone, region, location, diskProjectID string,

   	ctx := context.Background()
   
   	snapshotsClient, err := compute.NewSnapshotsRESTClient(ctx)
   	if err != nil {
   		return fmt.Errorf("NewSnapshotsRESTClient: %w", err)
   	}
   	defer snapshotsClient.Close()
   
   	if zone == "" && region == "" {
   		return fmt.Errorf("you need to specify `zone` or `region` for this function to work")
   	}
   
   	if zone != "" && region != "" {
   		return fmt.Errorf("you can't set both `zone` and `region` parameters")
   	}
   
   	if diskProjectID == "" {
   		diskProjectID = projectID
   	}
   
   	disk := &computepb.Disk{}
   	locations := []string{}
   	if location != "" {
   		locations = append(locations, location)
   	}
   
   	if zone != "" {
   		disksClient, err := compute.NewDisksRESTClient(ctx)
   		if err != nil {
   			return fmt.Errorf("NewDisksRESTClient: %w", err)
   		}
   		defer disksClient.Close()
   
   		getDiskReq := &computepb.GetDiskRequest{

   		if err != nil {
   			return fmt.Errorf("NewRegionDisksRESTClient: %w", err)
   		}
   		defer regionDisksClient.Close()
   
   		getDiskReq := &computepb.GetRegionDiskRequest{
   			Project: projectID,
   			Region:  region,
   			Disk:    diskName,

   	}
   
   	fmt.Fprintf(w, "Snapshot created\n")
   
   	return nil
   }
   

4. Exclua sua VM da zona de origem.

   import (
   	"context"
   	"fmt"
   	"io"
   
   	compute "cloud.google.com/go/compute/apiv1"

   	// instanceName := "your_instance_name"
   	ctx := context.Background()
   	instancesClient, err := compute.NewInstancesRESTClient(ctx)
   	if err != nil {
   		return fmt.Errorf("NewInstancesRESTClient: %w", err)
   	}
   	defer instancesClient.Close()
   
   	req := &computepb.DeleteInstanceRequest{
   		Project:  projectID,
   		Zone:     zone,
   		Instance: instanceName,
   	}
   
   	op, err := instancesClient.Delete(ctx, req)
   	if err != nil {
   		return fmt.Errorf("unable to delete instance: %w", err)
   	}
   
   	if err = op.Wait(ctx); err != nil {
   		return fmt.Errorf("unable to wait for the operation: %w", err)
   	}
   
   	fmt.Fprintf(w, "Instance deleted\n")
   
   	return nil
   }
   

5. Em seguida, crie outro instantâneo do disco de inicialização e dos discos de dados.

   		}
   
   		disk, err = regionDisksClient.Get(ctx, getDiskReq)
   		if err != nil {

   	op, err := snapshotsClient.Insert(ctx, req)
   	if err != nil {
   		return fmt.Errorf("unable to create snapshot: %w", err)
   	}
   
   	if err = op.Wait(ctx); err != nil {
   		return fmt.Errorf("unable to wait for the operation: %w", err)
   	}
   
   	fmt.Fprintf(w, "Snapshot created\n")
   
   	return nil
   }
   

6. (Opcional) Exclua seus discos permanentes.

   Se você planeja reutilizar os nomes dos discos permanentes para os novos discos, deverá excluir os discos existentes para liberar os nomes. Excluir seus discos também economiza custos de armazenamento em disco persistente.

   Se você não planeja reutilizar os mesmos nomes de disco, não será necessário excluí-los.

   import (

   	}
   
   	fmt.Fprintf(w, "Disk deleted\n")
   
   	return nil
   }
   

7. Crie novos discos permanentes na zona de destino a partir dos snapshots que você criou. Primeiro crie o disco de inicialização e depois os discos de dados.

   import (
   	"context"
   	"fmt"
   	"io"
   
   	compute "cloud.google.com/go/compute/apiv1"

   	}
   	defer disksClient.Close()
   
   	req := &computepb.InsertDiskRequest{
   		Project: projectID,
   		Zone:    zone,
   		DiskResource: &computepb.Disk{
   			Name:           proto.String(diskName),
   			Zone:           proto.String(zone),
   			Type:           proto.String(diskType),
   			SourceSnapshot: proto.String(snapshotLink),
   			SizeGb:         proto.Int64(diskSizeGb),
   		},
   	}
   
   	op, err := disksClient.Insert(ctx, req)
   	if err != nil {
   		return fmt.Errorf("unable to create disk: %w", err)
   	}
   
   	if err = op.Wait(ctx); err != nil {
   		return fmt.Errorf("unable to wait for the operation: %w", err)
   	}
   
   	fmt.Fprintf(w, "Disk created\n")
   
   	return nil
   }
   

8. Recrie sua VM com os novos discos na zona de destino.

   import (

   	"io"
   
   	compute "cloud.google.com/go/compute/apiv1"
   	computepb "cloud.google.com/go/compute/apiv1/computepb"
   	"google.golang.org/protobuf/proto"
   )
   
   // createWithExistingDisks create a new VM instance using selected disks.
   // The first disk in diskNames will be used as boot disk.
   func createWithExistingDisks(
   	w io.Writer,

         System.out.printf("Retrieved the instance %s", instance.toString());
       }
     }
   }

2. Defina o estado de exclusão automática do disco de inicialização e do disco de dados como false para garantir que os discos não sejam excluídos automaticamente quando a VM for excluída.

3. Crie backups dos seus dados usando snapshots de discos permanentes.

   Como precaução, crie backups dos seus dados enquanto os discos permanentes ainda estão anexados à VM usando snapshots de discos persistentes. Antes de criar um snapshot, certifique-se de que ele seja consistente com o estado do disco permanente seguindo as práticas recomendadas para snapshots .

   Depois de limpar os buffers de disco, crie os snapshots:

   Se você planeja reutilizar os nomes dos discos permanentes para os novos discos, deverá excluir os discos existentes para liberar os nomes. Excluir seus discos também economiza custos de armazenamento em disco persistente.

   Se você não planeja reutilizar os mesmos nomes de disco, não será necessário excluí-los.

         }
   
         System.out.println("Snapshot deleted!");
       }
     }
   }

Node.js

1. Obtenha os detalhes da VM e identifique os discos anexados à VM.

   /**
    * TODO(developer): Uncomment and replace these variables before running the sample.
    */
   // const projectId = 'YOUR_PROJECT_ID';
   // const zone = 'europe-central2-b'
   // const instanceName = 'YOUR_INSTANCE_NAME'
   
   const compute = require('@google-cloud/compute');
   
   async function getInstance() {
     const instancesClient = new compute.InstancesClient();
   
     const [instance] = await instancesClient.get({
       project: projectId,
       zone,
       instance: instanceName,
     });
   
     console.log(
       `Instance ${instanceName} data:\n${JSON.stringify(instance, null, 4)}`
     );
   }
   getInstance();

2. Defina o estado de exclusão automática do disco de inicialização e do disco de dados como false para garantir que os discos não sejam excluídos automaticamente quando a VM for excluída.

   /**
    * TODO(developer): Uncomment and replace these variables before running the sample.
    */
   // const projectId = 'YOUR_PROJECT_ID';
   // const zone = 'europe-central2-b';
   // const instanceName = 'YOUR_INSTANCE_NAME';
   // const diskName = 'YOUR_DISK_NAME';
   // const autoDelete = true;
   
   const compute = require('@google-cloud/compute');
   
   async function setDiskAutodelete() {
     const instancesClient = new compute.InstancesClient();
   
     const [instance] = await instancesClient.get({
       project: projectId,
       zone,
       instance: instanceName,
     });
   
     if (!instance.disks.some(disk => disk.deviceName === diskName)) {
       throw new Error(
         `Instance ${instanceName} doesn't have a disk named ${diskName} attached.`
       );
     }
   
     const [response] = await instancesClient.setDiskAutoDelete({
       project: projectId,
       zone,
       instance: instanceName,
       deviceName: diskName,
       autoDelete,
     });
     let operation = response.latestResponse;
     const operationsClient = new compute.ZoneOperationsClient();
   
     // Wait for the update instance operation to complete.
     while (operation.status !== 'DONE') {
       [operation] = await operationsClient.wait({
         operation: operation.name,
         project: projectId,
         zone: operation.zone.split('/').pop(),
       });
     }
   
     console.log('Disk autoDelete field updated.');
   }
   
   setDiskAutodelete();

3. Crie backups dos seus dados usando snapshots de discos permanentes.

   Como precaução, crie backups dos seus dados enquanto os discos permanentes ainda estão anexados à VM usando snapshots de discos permanentes. Antes de criar um snapshot, certifique-se de que ele seja consistente com o estado do disco permanente seguindo as práticas recomendadas para snapshots .

   Depois de limpar os buffers de disco, crie os snapshots:

   /**
    * TODO(developer): Uncomment and replace these variables before running the sample.
    */
   // const projectId = 'YOUR_PROJECT_ID';
   // const diskName = 'YOUR_DISK_NAME';
   // const snapshotName = 'YOUR_SNAPSHOT_NAME';
   // const zone = 'europe-central2-b';
   // const region = '';
   // const location = 'europe-central2';
   // let diskProjectId = 'YOUR_DISK_PROJECT_ID';
   
   const compute = require('@google-cloud/compute');
   
   async function createSnapshot() {
     const snapshotsClient = new compute.SnapshotsClient();
   
     let disk;
   
     if (!zone && !region) {
       throw new Error(
         'You need to specify `zone` or `region` for this function to work.'
       );
     }
   
     if (zone && region) {
       throw new Error("You can't set both `zone` and `region` parameters");
     }
   
     if (!diskProjectId) {
       diskProjectId = projectId;
     }
   
     if (zone) {
       const disksClient = new compute.DisksClient();
       [disk] = await disksClient.get({
         project: diskProjectId,
         zone,
         disk: diskName,
       });
     } else {
       const regionDisksClient = new compute.RegionDisksClient();
       [disk] = await regionDisksClient.get({
         project: diskProjectId,
         region,
         disk: diskName,
       });
     }
   
     const snapshotResource = {
       name: snapshotName,
       sourceDisk: disk.selfLink,
     };
   
     if (location) {
       snapshotResource.storageLocations = [location];
     }
   
     const [response] = await snapshotsClient.insert({
       project: projectId,
       snapshotResource,
     });
     let operation = response.latestResponse;
     const operationsClient = new compute.GlobalOperationsClient();
   
     // Wait for the create snapshot operation to complete.
     while (operation.status !== 'DONE') {
       [operation] = await operationsClient.wait({
         operation: operation.name,
         project: projectId,
       });
     }
   
     console.log('Snapshot created.');
   }
   
   createSnapshot();

4. Exclua sua VM da zona de origem.

   /**
    * TODO(developer): Uncomment these variables before running the sample.
    */
   // const projectId = 'YOUR_PROJECT_ID';
   // const zone = 'europe-central2-b'
   // const instanceName = 'YOUR_INSTANCE_NAME';
   
   const compute = require('@google-cloud/compute');
   
   // Delete the instance specified by `instanceName` if it's present in the given project and zone.
   async function deleteInstance() {
     const instancesClient = new compute.InstancesClient();
   
     console.log(`Deleting ${instanceName} from ${zone}...`);
   
     const [response] = await instancesClient.delete({
       project: projectId,
       zone,
       instance: instanceName,
     });
     let operation = response.latestResponse;
     const operationsClient = new compute.ZoneOperationsClient();
   
     // Wait for the delete operation to complete.
     while (operation.status !== 'DONE') {
       [operation] = await operationsClient.wait({
         operation: operation.name,
         project: projectId,
         zone: operation.zone.split('/').pop(),
       });
     }
   
     console.log('Instance deleted.');
   }
   
   deleteInstance();

5. Em seguida, crie outro instantâneo do disco de inicialização e dos discos de dados.

   /**
    * TODO(developer): Uncomment and replace these variables before running the sample.
    */
   // const projectId = 'YOUR_PROJECT_ID';
   // const diskName = 'YOUR_DISK_NAME';
   // const snapshotName = 'YOUR_SNAPSHOT_NAME';
   // const zone = 'europe-central2-b';
   // const region = '';
   // const location = 'europe-central2';
   // let diskProjectId = 'YOUR_DISK_PROJECT_ID';
   
   const compute = require('@google-cloud/compute');
   
   async function createSnapshot() {
     const snapshotsClient = new compute.SnapshotsClient();
   
     let disk;
   
     if (!zone && !region) {
       throw new Error(
         'You need to specify `zone` or `region` for this function to work.'
       );
     }
   
     if (zone && region) {
       throw new Error("You can't set both `zone` and `region` parameters");
     }
   
     if (!diskProjectId) {
       diskProjectId = projectId;
     }
   
     if (zone) {
       const disksClient = new compute.DisksClient();
       [disk] = await disksClient.get({
         project: diskProjectId,
         zone,
         disk: diskName,
       });
     } else {
       const regionDisksClient = new compute.RegionDisksClient();
       [disk] = await regionDisksClient.get({
         project: diskProjectId,
         region,
         disk: diskName,
       });
     }
   
     const snapshotResource = {
       name: snapshotName,
       sourceDisk: disk.selfLink,
     };
   
     if (location) {
       snapshotResource.storageLocations = [location];
     }
   
     const [response] = await snapshotsClient.insert({
       project: projectId,
       snapshotResource,
     });
     let operation = response.latestResponse;
     const operationsClient = new compute.GlobalOperationsClient();
   
     // Wait for the create snapshot operation to complete.
     while (operation.status !== 'DONE') {
       [operation] = await operationsClient.wait({
         operation: operation.name,
         project: projectId,
       });
     }
   
     console.log('Snapshot created.');
   }
   
   createSnapshot();

6. (Opcional) Exclua seus discos permanentes.

   Se você planeja reutilizar os nomes dos discos permanentes para os novos discos, deverá excluir os discos existentes para liberar os nomes. Excluir seus discos também economiza custos de armazenamento em disco persistente.

   Se você não planeja reutilizar os mesmos nomes de disco, não será necessário excluí-los.

   /**
    * TODO(developer): Uncomment and replace these variables before running the sample.

   // const projectId = 'YOUR_PROJECT_ID';
   // const zone = 'europe-central2-b';
   // const diskName = 'YOUR_DISK_NAME';
   
   const compute = require('@google-cloud/compute');
   
   async function deleteDisk() {
     const disksClient = new compute.DisksClient();
   
     const [response] = await disksClient.delete({

     while (operation.status !== 'DONE') {
       [operation] = await operationsClient.wait({

         project: projectId,
         zone: operation.zone.split('/').pop(),
       });
     }
   
     console.log('Disk deleted.');
   }
   
   deleteDisk();

7. Crie novos discos permanentes na zona de destino a partir dos snapshots que você criou. Primeiro crie o disco de inicialização e depois os discos de dados.

   /**
    * TODO(developer): Uncomment and replace these variables before running the sample.
    */
   // const projectId = 'YOUR_PROJECT_ID';
   // const zone = 'europe-central2-b';
   // const diskName = 'YOUR_DISK_NAME';
   // const diskType = 'zones/us-west3-b/diskTypes/pd-ssd';
   // const diskSizeGb = 10;
   // const snapshotLink = 'projects/project_name/global/snapshots/snapshot_name';
   
   const compute = require('@google-cloud/compute');
   
   async function createDiskFromSnapshot() {
     const disksClient = new compute.DisksClient();
   
     const [response] = await disksClient.insert({
       project: projectId,
       zone,
       diskResource: {
         sizeGb: diskSizeGb,
         name: diskName,
         zone,
         type: diskType,
         sourceSnapshot: snapshotLink,
       },
     });
     let operation = response.latestResponse;
     const operationsClient = new compute.ZoneOperationsClient();
   
     // Wait for the create disk operation to complete.
     while (operation.status !== 'DONE') {
       [operation] = await operationsClient.wait({
         operation: operation.name,
         project: projectId,
         zone: operation.zone.split('/').pop(),
       });
     }
   
     console.log('Disk created.');
   }
   
   createDiskFromSnapshot();

8. Recrie sua VM com os novos discos na zona de destino.

   /**
    * TODO(developer): Uncomment and replace these variables before running the sample.
    */
   // const projectId = 'YOUR_PROJECT_ID';
   // const zone = 'europe-central2-b';
   // const instanceName = 'YOUR_INSTANCE_NAME';
   // const diskNames = ['boot_disk', 'disk1', 'disk2'];
   
   const compute = require('@google-cloud/compute');
   
   async function createWithExistingDisks() {
     const instancesClient = new compute.InstancesClient();
     const disksClient = new compute.DisksClient();
   
     if (diskNames.length < 1) {
       throw new Error('At least one disk should be provided');
     }
   
     const disks = [];
     for (const diskName of diskNames) {
       const [disk] = await disksClient.get({
         project: projectId,
         zone,
         disk: diskName,
       });
       disks.push(disk);
     }
   
     const attachedDisks = [];
   
     for (const disk of disks) {
       attachedDisks.push({
         source: disk.selfLink,
       });
     }
   
     attachedDisks[0].boot = true;
   
     const [response] = await instancesClient.insert({
       project: projectId,
       zone,
       instanceResource: {
         name: instanceName,
         disks: attachedDisks,
         machineType: `zones/${zone}/machineTypes/n1-standard-1`,
         networkInterfaces: [
           {
             name: 'global/networks/default',
           },
         ],
       },
     });
     let operation = response.latestResponse;
     const operationsClient = new compute.ZoneOperationsClient();
   
     // Wait for the create operation to complete.
     while (operation.status !== 'DONE') {
       [operation] = await operationsClient.wait({
         operation: operation.name,
         project: projectId,
         zone: operation.zone.split('/').pop(),
       });
     }
   
     console.log('Instance created.');
   }
   
   createWithExistingDisks();

9. (Opcional) Exclua os instantâneos de disco temporários. Depois de confirmar que suas máquinas virtuais foram movidas, economize nos custos de armazenamento excluindo os instantâneos temporários que você criou.

   /**
    * TODO(developer): Uncomment and replace these variables before running the sample.
    */
   // const projectId = 'YOUR_PROJECT_ID';
   // const snapshotName = 'YOUR_SNAPSHOT_NAME';
   
   const compute = require('@google-cloud/compute');
   
   async function deleteSnapshot() {
     const snapshotsClient = new compute.SnapshotsClient();
   
     const [response] = await snapshotsClient.delete({
       project: projectId,
       snapshot: snapshotName,
     });
     let operation = response.latestResponse;
     const operationsClient = new compute.GlobalOperationsClient();
   
     // Wait for the create disk operation to complete.
     while (operation.status !== 'DONE') {
       [operation] = await operationsClient.wait({
         operation: operation.name,
         project: projectId,
       });
     }
   
     console.log('Snapshot deleted.');
   }
   
   deleteSnapshot();
