Converta imagem para o formato RAW no Google Cloud

Colaboradores
PDFs

A imagem que está a ser utilizada para implementar novas instâncias, atualizações ou a ser utilizada em imagens existentes será partilhada com os clientes através "O site de suporte da NetApp (NSS)"do . O resumo assinado e os certificados estarão disponíveis para download através do portal NSS. Certifique-se de que está a transferir o resumo e os certificados para a versão correta correspondente à imagem partilhada pelo suporte da NetApp. Por exemplo, as imagens 9.13.0D terão um resumo assinado 9.13.0D e certificados disponíveis no NSS.

Por que esse passo é necessário?

As imagens do Google Cloud não podem ser baixadas diretamente. Para verificar a imagem em relação ao resumo assinado e aos certificados, você precisa ter um mecanismo para comparar os dois arquivos e baixar a imagem. Para fazer isso, você deve exportar/converter a imagem em um formato Disk.Raw e salvar os resultados em um bucket de storage no Google Cloud. O arquivo Disk.RAW é tarred e gzip no processo.

A conta de usuário/serviço precisará do Privileges para executar o seguinte:

  • Acesso ao bucket de armazenamento do Google

  • Escreva para o bucket do Google Storage

  • Criar trabalhos de compilação na nuvem (usados durante o processo de exportação)

  • Acesso à imagem pretendida

  • Criar tarefas de exportação de imagem

Para verificar a imagem, ela deve ser convertida em um formato Disk.Raw e, em seguida, baixada.

Use a linha de comando do Google Cloud para exportar a imagem do Google Cloud

A maneira preferida de exportar uma imagem para o Cloud Storage é usar o "comando de exportação de imagens de computação gcloud". Este comando pega a imagem fornecida e converte-a em um arquivo Disk.Raw que fica em tarred e gzip. O arquivo gerado é salvo no URL de destino e pode ser baixado para verificação.

O usuário/conta deve ter Privileges para acessar e gravar no bucket desejado, exportar a imagem e compilações na nuvem (usadas pelo Google para exportar a imagem) para executar esta operação.

  • Exportar imagem do Google Cloud usando gcloud*

Clique para apresentar 
$ gcloud compute images export \
    --destination-uri DESTINATION_URI \
    --image IMAGE_NAME

# For our example:
$ gcloud compute images export \
    --destination-uri gs://vsa-dev-bucket1/example-user-exportimage-gcp-demo \
    --image example-user-20230120115139


## DEMO ##
# Step 1 - Optional: Checking access and listing objects in the destination bucket
$ gsutil ls gs://example-user-export-image-bucket/

# Step 2 - Exporting the desired image to the bucket
$ gcloud compute images export --image example-user-export-image-demo --destination-uri gs://example-user-export-image-bucket/export-demo.tar.gz
