Peer

class aws_cdk.aws_ec2.Peer

Bases: object

Peer object factories (to be used in Security Group management).

The static methods on this object can be used to create peer objects which represent a connection partner in Security Group rules.

Use this object if you need to represent connection partners using plain IP addresses, or a prefix list ID.

If you want to address a connection partner by Security Group, you can just use the Security Group (or the construct that contains a Security Group) directly, as it already implements IPeer.

Example:

# instance_type: ec2.InstanceType


provider = ec2.NatProvider.instance(
    instance_type=instance_type,
    default_allowed_traffic=ec2.NatTrafficDirection.OUTBOUND_ONLY
)
ec2.Vpc(self, "TheVPC",
    nat_gateway_provider=provider
)
provider.connections.allow_from(ec2.Peer.ipv4("1.2.3.4/8"), ec2.Port.tcp(80))
