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

declare const vpc: ec2.Vpc;
const cluster = new msk.Cluster(this, 'Cluster', {
  clusterName: 'myCluster',
  kafkaVersion: msk.KafkaVersion.V2_8_1,
  vpc,
});

cluster.connections.allowFrom(
  ec2.Peer.ipv4('1.2.3.4/8'),
  ec2.Port.tcp(2181),
);
cluster.connections.allowFrom(
  ec2.Peer.ipv4('1.2.3.4/8'),
  ec2.Port.tcp(9094),
);
