Interromper ou reiniciar uma VM

Neste documento, explicamos como interromper, reiniciar, redefinir ou reiniciar manualmente uma instância de máquina virtual (VM). Essas operações são úteis nos seguintes cenários:

  • Interrompa uma VM se ela não for mais usada ou se você quiser modificar uma ou mais propriedades dela. Por exemplo, se você quiser renomear a VM, alterar o tipo de máquina, adicionar ou remover discos anexados ou alterar a plataforma mínima da CPU. Depois de interromper a VM, reinicie-a para retomar a carga de trabalho ou exclua a VM se ela não for mais necessária.

  • Redefina a VM se, por exemplo, ela não responder ou se o sistema operacional (SO) convidado tiver falhado. Depois de redefinir a VM, é possível retomar sua carga de trabalho.

  • Reinicialize uma VM no SO convidado se, por exemplo, você quiser limpar a memória da VM e reinicializá-la para o estado de inicialização original. Depois de reiniciar uma VM no SO convidado, é possível retomar a carga de trabalho.

Antes de começar

  • Configure a autenticação, caso ainda não tenha feito isso. A autenticação é o processo de verificação da sua identidade para acesso a serviços e APIs do Google Cloud. Para executar códigos ou amostras de um ambiente de desenvolvimento local, autentique-se no Compute Engine da seguinte maneira.

Funções exigidas

Para receber as permissões necessárias para interromper e reiniciar uma VM, peça ao administrador para conceder a você o papel de Administrador da instância do Compute (v1) (roles/compute.instanceAdmin.v1) do IAM no projeto. Para mais informações sobre a concessão de papéis, consulte Gerenciar o acesso a projetos, pastas e organizações.

Esse papel predefinido contém as permissões necessárias para interromper e reiniciar uma VM. Para conferir as permissões exatas necessárias, expanda a seção Permissões necessárias:

Permissões necessárias

As permissões a seguir são necessárias para interromper e reiniciar uma VM:

  • Para interromper uma VM: compute.instances.stop na VM
  • Para interromper uma VM no SO convidado: compute.instances.setMetadata na VM se ela usar chaves SSH públicas no nível da instância.
  • Para reiniciar uma VM: compute.instances.start na VM
  • Para reiniciar uma VM que usa chaves de criptografia: compute.instances.startWithEncryptionKey na VM
  • Para redefinir uma VM: compute.instances.reset na VM
  • Para reiniciar uma VM no SO convidado: compute.instances.setMetadata na VM

Essas permissões também podem ser concedidas com funções personalizadas ou outros papéis predefinidos.

Interromper uma VM

Quando você interrompe uma VM em execução, acontece o seguinte:

  1. O Compute Engine envia o sinal de encerramento ACPI para a VM e aguarda um breve período para que o SO convidado execute um encerramento limpo. Em seguida, o Compute Engine define o estado da VM como STOPPING primeiro e, em seguida, faz a transição para TERMINATED em um minuto.

  2. A VM é redefinida para o estado de ativação e mantém os IPs internos, endereços MAC, definições de configuração e metadados. No entanto, a VM perde os dados na memória e o estado da VM. Se for necessário manter os dados na memória e o estado da VM, suspenda a VM.

Além disso, se você anexou recursos à VM, eles permanecem anexados até que você os desanexe manualmente ou exclua a VM. Se a VM tiver algum disco SSD local anexado, interromper a VM descartará todos os dados nos discos SSD locais por padrão. Para manter os dados nos discos SSD locais, interrompa a VM usando a CLI gcloud com a sinalização --discard-local-ssd=false. Para mais informações, consulte Interromper uma VM com SSD local.

Para interromper uma VM, selecione um dos métodos descritos neste documento:

Depois de interromper uma VM, é possível reiniciá-la ou excluí-la. Se você não planeja reiniciar a VM, é recomendável excluí-la.

interromper uma VM pelo Google Cloud

Para interromper mais de uma VM por vez, use o console do Google Cloud.

Console

Para interromper uma ou mais VMs, faça o seguinte:

  1. No console do Google Cloud, acesse a página Instâncias de VMs.

    Acessar instâncias de VM

  2. Selecione as VMs que você quer interromper.

  3. Clique em Parar e, em seguida, em Parar para confirmar.

gcloud

Para interromper uma VM, use o comando gcloud compute instances stop:

gcloud compute instances stop VM_NAME \
    --project=PROJECT_ID \
    --zone=ZONE

Substitua:

  • VM_NAME: o nome da VM.

  • PROJECT_ID: o ID do projeto em que a VM está localizada.

  • ZONE: a zona em que a VM está localizada.

Se você anexou um disco SSD local à VM e quer manter os dados do SSD local após interromper a VM, use o comando gcloud beta compute instances stop com --discard-local-ssd=false.

gcloud beta compute instances stop VM_NAME \
    --discard-local-ssd=false \
    --project=PROJECT_ID \
    --zone=ZONE

  • ENCRYPTION_KEY: a chave de criptografia usada para criptografar os discos permanentes anexados à VM. As chaves rawKey ou rsaEncryptedKey precisam ser codificadas em base64. Além disso, para preparar uma chave rsaEncryptedKey, consulte Encapsulamento de chaves por RSA.

Redefina uma VM

Redefinir uma VM em execução é semelhante a uma reinicialização forçada no computador, por exemplo, pressionar um botão de redefinição ou tocar e pressionar o botão liga/desliga. Ao redefinir uma VM, você não dá tempo a ela para executar um encerramento limpo do SO convidado. Consequentemente, os sistemas de arquivos do disco podem ser corrompidos. O Google Cloud recomenda redefinir uma VM somente se o SO convidado tiver falhado e você não tiver outras opções. Se você quiser reinicializar uma VM e executar um encerramento limpo, consulte Reiniciar uma VM neste documento.

Ao redefinir uma VM, acontece o seguinte:

  • A VM é reinicializada para o estado de inicialização inicial com os metadados, a imagem e os discos permanentes originais.

  • A VM força a exclusão permanente do conteúdo da memória, a menos que você faça backup dos dados.

  • O estado da VM permanece RUNNING durante o processo.

Redefinir uma VM não altera nenhuma das propriedades da VM. A VM mantém IPs temporários, IPs estáticos externos, discos permanentes, discos SSD locais (se houver) e tipo de máquina.

Console

Para redefinir uma ou mais VMs em execução, siga estas etapas:

  1. No console do Google Cloud, acesse a página Instâncias de VMs.

    Acessar instâncias de VM

  2. Selecione as VMs que você quer redefinir.

  3. Clique em Redefinir e, em seguida, clique em Redefinir novamente.

gcloud

Para redefinir uma VM em execução, use o comando gcloud compute instances reset.

gcloud compute instances reset VM_NAME \
    --project=PROJECT_ID \
    --zone=ZONE

Substitua:

  • VM_NAME: o nome da VM.

  • PROJECT_ID: o ID do projeto em que a VM está localizada.

  • ZONE: a zona em que a VM está localizada.

REST

Para redefinir uma VM em execução, faça uma solicitação POST para o método instances.reset.

 POST https://www.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/instances/VM_NAME/reset

Substitua:

  • VM_NAME: o nome da VM.

  • PROJECT_ID: o ID do projeto em que a VM está localizada.

  • ZONE: a zona em que a VM está localizada.

Reinicializar uma VM

Quando você reinicializa uma VM no SO convidado, acontece o seguinte:

  • A VM é reinicializada para o estado de inicialização inicial com os metadados, a imagem e os discos permanentes originais.

  • A VM exclui permanentemente o conteúdo da memória da máquina, a menos que você faça backup dos dados.

  • O estado da VM permanece RUNNING durante o processo.

Em comparação com a redefinição de uma VM, reinicializar uma VM no SO convidado aguarda que a VM conclua todas as tarefas em execução antes de enviar o sinal de encerramento da ACPI para a VM. Isso permite que a VM execute um encerramento limpo.

Reiniciar uma VM não altera nenhuma das propriedades da VM. A VM mantém IPs temporários, IPs estáticos externos, discos permanentes, discos SSD locais (se houver) e tipo de máquina.

Linux

Para redefinir uma VM do Linux, reinicialize o SO convidado executando o seguinte comando:

sudo reboot

Windows

Para redefinir uma VM do Windows, reinicialize o SO convidado executando o seguinte comando:

shutdown /r /t 0

Se quiser monitorar o processo de encerramento e reinicialização da VM, ative o menu do Gerenciador de Inicialização do Windows.

Faturamento

Depois que uma VM é interrompida e o Compute Engine define o estado dela como TERMINATED, não há mais cobranças pelo uso da CPU. No entanto, você continua sendo cobrado por todos os recursos anexados à VM, como discos permanentes e endereços IP externos.

Para interromper as cobranças pelos recursos anexados a uma VM, siga um seguinte:

  • Remova esses recursos da VM interrompida.

  • Exclua a VM. Essa ação também exclui todos os recursos anexados à VM.
