BuildInstanceSecurityGroup

The security group to assign to build instances. If blank, the Rack uses the same security group as the runtime instances (or the value of InstanceSecurityGroup if set).

| Default value | "" |

Use Cases

  • Isolating build instance network access from runtime instances for security compliance
  • Granting build instances access to specific internal resources (e.g., private artifact repositories, license servers) that runtime instances should not reach
  • Restricting outbound internet access on build instances in regulated environments

Additional Information

The security group must exist in the same VPC as the Rack. When specifying a custom security group, ensure it allows the necessary outbound access for pulling Docker images, accessing ECR, and communicating with the ECS control plane.
