Associating a Security Group with a Cluster
Each cluster you provision has one or more security groups associated with it.You can associate a
security group with a cluster when you create the cluster, or you can associate a security group later by
modifying the cluster. For more information, see To create a cluster (p. 8) and To modify a cluster (p. 13).
Managing Security Groups Using AWS SDK for
Java
The following example demonstrates common operations on security groups, including:
• Creating a new security group
• Adding ingress rules to a security group
• Associating a security group with a cluster by modifying the cluster configuration.
By default, when a new security group is created, it has no ingress rules.This example modifies a new
security group by adding two ingress rules. One ingress rule is added by specifying a CIDR/IP range; the
other is added by specifying an owner ID and Amazon EC2 security group combination.
For step-by-step instructions to run the following example, see Running Java Examples for Amazon
Redshift Using Eclipse (p. 118).You need to update the code and provide a cluster identifier and AWS
account number.
