Exemplo 2: para filtrar instâncias com o tipo especificado

O exemplo describe-instances a seguir usa filtros para definir o escopo dos resultados para instâncias do tipo especificado.

aws ec2 describe-instances \
    --filters Name=instance-type,Values=m5.large

Para obter um exemplo da saída, consulte o Exemplo 1.

Para obter mais informações, consulte Listar e filtrar usando a CLI no Guia do usuário do Amazon EC2.

Exemplo 3: filtrar instâncias com o tipo e a zona de disponibilidade especificados

O exemplo describe-instances a seguir usa vários filtros para definir o escopo dos resultados para instâncias com o tipo especificado que também estão na zona de disponibilidade especificada.

aws ec2 describe-instances \
    --filters file://filters.json

Conteúdo de filters.json:

[
    {
        "Name": "instance-type",
        "Values": ["t2.micro", "t3.micro"]
    },
    {
