#### [ CLI ]

**AWS CLI**  
**Esempio 1: come avviare un’istanza in una sottorete predefinita**  
Nell’esempio di `run-instances` seguente viene avviata una singola istanza di tipo `t2.micro` nella sottorete predefinita per la regione attuale e viene associata alla sottorete predefinita per il VPC predefinito per la regione. La coppia di chiavi è opzionale se non si desidera collegare l’istanza tramite SSH (Linux) o RDP (Windows).  

```
aws ec2 run-instances \
    --image-id ami-0abcdef1234567890 \

**Esempio 2: come avviare un’istanza in una sottorete non predefinita e aggiungere un indirizzo IP pubblico**  
Nell’esempio di `run-instances` seguente viene richiesto un indirizzo IP pubblico per un’istanza avviata in una sottorete non predefinita. L’istanza è associata al gruppo di sicurezza specificato.  

```
aws ec2 run-instances \
    --image-id ami-0abcdef1234567890 \
    --instance-type t2.micro \
    --subnet-id subnet-08fc749671b2d077c \
    --security-group-ids sg-0b0384b66d7d692f9 \
    --associate-public-ip-address \
    --key-name MyKeyPair
```
Per un esempio dell’output di `run-instances`, consulta l’Esempio 1.  
**Esempio 3: come avviare un’istanza con volumi aggiuntivi**  
Nell’esempio di `run-instances` seguente viene utilizzata una mappatura dei dispositivi a blocchi, specificata in mapping.json, per collegare volumi aggiuntivi al momento del lancio. Una mappatura dei dispositivi a blocchi può specificare volumi EBS, oppure sia volumi EBS e volumi di archivio dell’istanza.  

```
aws ec2 run-instances \
    --image-id ami-0abcdef1234567890 \
    --instance-type t2.micro \
    --subnet-id subnet-08fc749671b2d077c \
    --security-group-ids sg-0b0384b66d7d692f9 \
    --key-name MyKeyPair \
    --block-device-mappings file://mapping.json
```
Contenuto di `mapping.json`. In questo esempio viene aggiunto `/dev/sdh`, un volume EBS vuoto della dimensione di 100 GiB.  

```
[
    {
        "DeviceName": "/dev/sdh",
        "Ebs": {
            "VolumeSize": 100
        }
    }
]
```
Contenuto di `mapping.json`. In questo esempio viene aggiunto `ephemeral1`, un volume di archivio dell’istanza.  

```
[
    {
        "DeviceName": "/dev/sdc",
        "VirtualName": "ephemeral1"
    }
]
```
Per un esempio dell’output di `run-instances`, consulta l’Esempio 1.  
Per ulteriori informazioni sulle mappature dei dispositivi a blocchi, consulta [Mappatura dei dispositivi a blocchi](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/block-device-mapping-concepts.html) nella *Guida per l’utente di Amazon EC2*.  
**Esempio 4: come avviare un’istanza e aggiungere tag al momento della creazione**  
Nell’esempio di `run-instances` seguente viene aggiunto un tag con una chiave `webserver` e un valore `production` all’istanza. Il comando avvia applica inoltre un tag con una chiave `cost-center` e un valore `cc123` a qualsiasi volume EBS creato, in questo caso il volume root.  

```
aws ec2 run-instances \
    --image-id ami-0abcdef1234567890 \
    --instance-type t2.micro \
    --count 1 \
    --subnet-id subnet-08fc749671b2d077c \
    --key-name MyKeyPair \
    --security-group-ids sg-0b0384b66d7d692f9 \
    --tag-specifications 'ResourceType=instance,Tags=[{Key=webserver,Value=production}]' 'ResourceType=volume,Tags=[{Key=cost-center,Value=cc123}]'
```
Per un esempio dell’output di `run-instances`, consulta l’Esempio 1.  
**Esempio 5: come avviare un’istanza con dati utente**  
Nell’esempio di `run-instances` seguente i dati utente vengono trasferiti in un file denominato `my_script.txt` che contiene uno script di configurazione per l’istanza. Lo script viene eseguito al momento dell’avvio.  

```
aws ec2 run-instances \
    --image-id ami-0abcdef1234567890 \
    --instance-type t2.micro \
    --count 1 \
    --subnet-id subnet-08fc749671b2d077c \
    --key-name MyKeyPair \
    --security-group-ids sg-0b0384b66d7d692f9 \
    --user-data file://my_script.txt
```
Per un esempio dell’output di `run-instances`, consulta l’Esempio 1.

**Esempio 6: come avviare un’istanza a prestazioni espandibili**  
Nell’esempio di `run-instances` seguente viene avviata un’istanza t2.micro con l’opzione di credito `unlimited`. All’avvio di un’istanza T2, se non si specifica `--credit-specification`, l’opzione di credito predefinita `standard`. All’avvio di un’istanza T3, l’opzione di credito predefinita è `unlimited`.  

```
aws ec2 run-instances \
    --image-id ami-0abcdef1234567890 \
    --instance-type t2.micro \
    --count 1 \
    --subnet-id subnet-08fc749671b2d077c \
    --key-name MyKeyPair \
    --security-group-ids sg-0b0384b66d7d692f9 \
    --credit-specification CpuCredits=unlimited
