Usar ModifyDBInstance com o AWS SDK ou a CLI

Exemplo 1: Como modificar uma instância de banco de dados

O exemplo de modify-db-instance a seguir associa um grupo de opção e um grupo de parâmetros a uma instância de banco de dados do Microsoft SQL Server compatível. O parâmetro --apply-immediately faz com que os grupos de opção e parâmetro sejam associados imediatamente em vez de ter que esperar a próxima janela de manutenção.

aws rds modify-db-instance \
    --db-instance-identifier database-2 \
    --option-group-name test-se-2017 \
    --db-parameter-group-name test-sqlserver-se-2017 \
    --apply-immediately

Saída:

Exemplo 2: Como associar um grupo de segurança a uma instância de banco de dados

O seguinte exemplo de modify-db-instance associa um grupo de segurança da VPC específico e remove grupos de segurança de banco de dados da instância de banco de dados:

aws rds modify-db-instance \
    --db-instance-identifier dbName \
    --vpc-security-group-ids sg-ID

Saída:

"DBInstance": {
    "DBInstanceIdentifier": "dbName",

            "Status": "active"
        }
    ],
    ... output omitted ...
