Per associare un indirizzo IP elastico in EC2 -Classic

Questo esempio associa un indirizzo IP elastico a un'istanza in EC2 -Classic. Se il comando va a buon fine, non viene restituito alcun output.

Comando:

aws ec2 associate-address --instance-id i-07ffe74c7330ebf53 --public-ip 198.51.100.0

Per associare un indirizzo IP elastico in - EC2 VPC

Questo esempio associa un indirizzo IP elastico a un'istanza in aVPC.

Comando:

aws ec2 associate-address --instance-id i-0b263919b6498b123 --allocation-id eipalloc-64d5890a

Output:

{ "AssociationId": "eipassoc-2bebb745" }

Nell'esempio seguente viene associato un indirizzo IP elastico a un'interfaccia di rete.

Comando:

aws ec2 associate-address --allocation-id eipalloc-64d5890a --network-interface-id eni-1a2b3c4d

Nell'esempio seguente viene associato un indirizzo IP elastico a un indirizzo IP privato associato a un'interfaccia di rete.

Comando:

aws ec2 associate-address --allocation-id eipalloc-64d5890a --network-interface-id eni-1a2b3c4d --private-ip-address 10.0.0.85

Esempio 1: Questo esempio associa l'indirizzo IP elastico specificato all'istanza specificata in aVPC.

C:\> Register-EC2Address -InstanceId i-12345678 -AllocationId eipalloc-12345678

Output:

eipassoc-12345678

Esempio 2: questo esempio associa l'indirizzo IP elastico specificato all'istanza specificata in EC2 -Classic.

C:\> Register-EC2Address -InstanceId i-12345678 -PublicIp 203.0.113.17
