#### [ CLI ]

**AWS CLI**  
**Exemplo 1: como criar um grupo do Auto Scaling**  
O exemplo de `create-auto-scaling-group` a seguir cria um grupo do Auto Scaling em sub-redes de várias zonas de disponibilidade de uma região. As instâncias são executadas com a versão padrão do modelo de execução especificado. Observe que os padrões são usados na maioria das outras configurações, como nas políticas de encerramento e na configuração de verificação de integridade.  

```
aws autoscaling create-auto-scaling-group \
    --auto-scaling-group-name my-asg \
    --launch-template LaunchTemplateId=lt-1234567890abcde12 \
    --min-size 1 \
    --max-size 5 \
    --vpc-zone-identifier "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782"
```
Este comando não produz saída.  
Para obter mais informações, consulte[ Grupos do Auto Scaling](https://docs.aws.amazon.com/autoscaling/ec2/userguide/AutoScalingGroup.html) no *Guia do usuário do Amazon EC2 Auto Scaling*.  
**Exemplo 2: como anexar o Application Load Balancer, o Network Load Balancer ou o Gateway Load Balancer**  
Este exemplo especifica o ARN de um grupo de destino para um balanceador de carga compatível com o tráfego esperado. O tipo de verificação de integridade especifica o `ELB`. Desta forma, quando o Elastic Load Balancing reportar uma instância como não íntegra, o grupo do Auto Scaling a substitui. O comando também define um período de carência de `600` segundos para a verificação de integridade. O período de carência ajuda a evitar o encerramento prematuro de instâncias recém-iniciadas.  

```
aws autoscaling create-auto-scaling-group \
    --auto-scaling-group-name my-asg \
    --launch-template LaunchTemplateId=lt-1234567890abcde12 \
    --target-group-arns arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/943f017f100becff \
    --health-check-type ELB \
    --health-check-grace-period 600 \
    --min-size 1 \
    --max-size 5 \
    --vpc-zone-identifier "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782"
```
Este comando não produz saída.  
Para obter mais informações, consulte [Elastic Load Balancing e Amazon EC2 Auto Scaling](https://docs.aws.amazon.com/autoscaling/ec2/userguide/autoscaling-load-balancer.html) no *Guia do usuário do Amazon EC2 Auto Scaling*.  
**Exemplo 3: como especificar um grupo de posicionamento e usar a versão mais recente do modelo de execução**  
Este exemplo executa instâncias em um grupo de posicionamento dentro de uma única zona de disponibilidade. Isso pode ser útil para grupos de baixa latência com workloads de HPC. Esse exemplo também especifica o tamanho mínimo e máximo e a capacidade desejada do grupo.  

```
aws autoscaling create-auto-scaling-group \
    --auto-scaling-group-name my-asg \
    --launch-template LaunchTemplateId=lt-1234567890abcde12,Version='$Latest' \
    --min-size 1 \
    --max-size 5 \
    --desired-capacity 3 \
    --placement-group my-placement-group \
    --vpc-zone-identifier "subnet-6194ea3b"
```
Este comando não produz saída.  
Para obter mais informações, consulte [Grupos de posicionamento](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html) no *Guia do usuário para instâncias do Linux do Amazon EC2*.  
**Exemplo 4: como especificar um grupo do Auto Scaling de instância única e usar uma versão específica para iniciar o modelo**  
Este exemplo cria um grupo do Auto Scaling com capacidade mínima e máxima definida como `1` para impor que uma apenas instância seja executada. O comando também especifica a v1 de um modelo de execução no qual o ID de um ENI existente é especificado. Ao usar um modelo de execução que especifica um ENI existente para eth0, é necessário especificar uma zona de disponibilidade para o grupo do Auto Scaling que corresponda à interface de rede, mas sem especificar um ID de sub-rede na solicitação.  

```
aws autoscaling create-auto-scaling-group \
    --auto-scaling-group-name my-asg-single-instance \
    --launch-template LaunchTemplateName=my-template-for-auto-scaling,Version='1' \
    --min-size 1 \
    --max-size 1 \
    --availability-zones us-west-2a
```
Este comando não produz saída.  
Para obter mais informações, consulte[ Grupos do Auto Scaling](https://docs.aws.amazon.com/autoscaling/ec2/userguide/AutoScalingGroup.html) no *Guia do usuário do Amazon EC2 Auto Scaling*.  
**Exemplo 5: como especificar uma política de encerramento diferente**  
Este exemplo cria um grupo do Auto Scaling usando uma configuração de execução e define a política de encerramento para encerrar as instâncias mais antigas primeiro. O comando também aplica uma tag ao grupo e suas instâncias, com uma chave `Role` e valor de `WebServer`.  

```
aws autoscaling create-auto-scaling-group \
    --auto-scaling-group-name my-asg \
    --launch-configuration-name my-lc \
    --min-size 1 \
    --max-size 5 \
    --termination-policies "OldestInstance" \
    --tags "ResourceId=my-asg,ResourceType=auto-scaling-group,Key=Role,Value=WebServer,PropagateAtLaunch=true" \
    --vpc-zone-identifier "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782"
```
Este comando não produz saída.  
Para obter mais informações, consulte [Trabalhar com políticas de término do Amazon EC2 Auto Scaling](https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-termination-policies.html) no *Guia do usuário do Amazon EC2 Auto Scaling*.  
**Exemplo 6: como especificar um gancho do ciclo de vida de lançamento**  
Este exemplo a seguir cria um grupo do Auto Scaling com um gancho do ciclo de vida que oferece suporte a uma ação personalizada na inicialização da instância.  

```
aws autoscaling create-auto-scaling-group \
    --cli-input-json file://~/config.json
```

# Usar `CreateOrUpdateTags` com uma CLI
<a name="auto-scaling_example_auto-scaling_CreateOrUpdateTags_section"></a>

Os exemplos de código a seguir mostram como usar o `CreateOrUpdateTags`.

------
#### [ CLI ]

**AWS CLI**  
**Para criar ou atualizar tags de um grupo do Auto Scaling**  
Este exemplo adiciona duas tags ao grupo do Auto Scaling especificado.  

```
aws autoscaling create-or-update-tags \
    --tags ResourceId=my-asg,ResourceType=auto-scaling-group,Key=Role,Value=WebServer,PropagateAtLaunch=true ResourceId=my-asg,ResourceType=auto-scaling-group,Key=Dept,Value=Research,PropagateAtLaunch=true
```
Este comando não produz saída.  
Para obter mais informações, consulte [Marcar instâncias e grupos de Auto Scaling](https://docs.aws.amazon.com/autoscaling/ec2/userguide/autoscaling-tagging.html) no *Guia do usuário do Amazon EC2 Auto Scaling*.

------
#### [ PowerShell ]

**Ferramentas para PowerShell V4**  
**Exemplo 1: Este exemplo adiciona uma única tag ao grupo do Auto Scaling especificado. A chave da tag é 'myTag' e o valor da tag é 'myTagValue'. O Auto Scaling propaga essa tag para as instâncias do EC2 subsequentes lançadas pelo grupo do Auto Scaling. A sintaxe usada neste exemplo requer a PowerShell versão 3 ou posterior.**  

```
Set-ASTag -Tag @( @{ResourceType="auto-scaling-group"; ResourceId="my-asg"; Key="myTag"; Value="myTagValue"; PropagateAtLaunch=$true} )
```
**Exemplo 2: Com a PowerShell versão 2, você deve usar New-Object para criar a tag para o parâmetro Tag.**  

```
$tag = New-Object Amazon.AutoScaling.Model.Tag
$tag.ResourceType = "auto-scaling-group"
$tag.ResourceId = "my-asg" 
$tag.Key = "myTag" 
$tag.Value = "myTagValue"
$tag.PropagateAtLaunch = $true
Set-ASTag -Tag $tag

#### [ CLI ]

**AWS CLI**  
**Exemplo 1: como descrever uma ou mais instâncias**  
Este exemplo descreve a instância especificada.  

```
aws autoscaling describe-auto-scaling-instances \
    --instance-ids i-06905f55584de02da
```
Saída:  

```
{
    "AutoScalingInstances": [
        {
            "InstanceId": "i-06905f55584de02da",
            "InstanceType": "t2.micro",
            "AutoScalingGroupName": "my-asg",
            "AvailabilityZone": "us-west-2b",
            "LifecycleState": "InService",
            "HealthStatus": "HEALTHY",
            "ProtectedFromScaleIn": false,
            "LaunchTemplate": {
                "LaunchTemplateId": "lt-1234567890abcde12",
                "LaunchTemplateName": "my-launch-template",
                "Version": "1"
            }
        }
    ]
}
```
**Exemplo 2: como descrever uma ou mais instâncias**  
Este exemplo usa a opção `--max-items` para especificar quantas instâncias devem ser retornadas pela chamada.  

```
aws autoscaling describe-auto-scaling-instances \
    --max-items 1
```
Se a saída incluir um campo `NextToken`, há mais instâncias. Para obter as instâncias adicionais, use o valor desse campo com a opção `--starting-token` em uma chamada subsequente da seguinte maneira.  

```
aws autoscaling describe-auto-scaling-instances \
    --starting-token Z3M3LMPEXAMPLE
```
Consulte uma amostra de saída no exemplo 1.  
**Exemplo 3: descrever instâncias que usam configurações de execução**  
Este exemplo usa a opção `--query` para descrever instâncias que usam configurações de execução.  

```
aws autoscaling describe-auto-scaling-instances \
    --query 'AutoScalingInstances[?LaunchConfigurationName!=`null`]'
```
Saída:  

```

Os exemplos de código a seguir mostram como usar o `PutScalingPolicy`.

------
#### [ CLI ]

**AWS CLI**  
**Para adicionar uma política de escalabilidade com monitoramento do objetivo a um grupo do Auto Scaling**  
O exemplo `put-scaling-policy` a seguir aplica uma política de escalabilidade de monitoramento de destino ao grupo do Auto Scaling especificado. A saída contém os nomes ARNs e dos dois CloudWatch alarmes criados em seu nome. Se já existir uma política de escalonamento com o mesmo nome, ela será substituída pela nova política de escalonamento.  

```
aws autoscaling put-scaling-policy --auto-scaling-group-name my-asg \
  --policy-name alb1000-target-tracking-scaling-policy \
  --policy-type TargetTrackingScaling \
  --target-tracking-configuration file://config.json
