v1.4.0

Features & Enhancements

1. Bring Your Own Network (BYON)

• Users can now select existing network resources (VCN, subnets, gateways, etc.) when creating a new cluster, enabling "Bring Your Own Network" capability via the use_existing_network option. Previously, the stack only allowed creation of new network resources for each cluster. With BYON, customers have finer control and flexibility in cluster networking.

2. Agent-Based Installation (ABI): Advanced Configurations & Disconnected Support

• Added new configuration options for Agent-based Installer (ABI), especially for disconnected. New output with pre-configured install-config.yaml and agent-config.yaml, to be used in conjunction with existing dynamic_custom_manifest. The create-cluster stack now supports creating a webserver for disconnected ABI to host the cluster installation process and the rootfs file for the instances.
