Jun 1, 2025June 2025: Delivered four major feature sets and reliability improvements for the NSX Operator, strengthening multi-tenant networking, IP governance, and diagnostics. Key outcomes include: - Namespace provisioning with pre-created VPCs (no NAT/LB): enables Namespace creation in simplified VPC configurations; updates NetworkInfo reconciliation to gracefully handle missing VPC attachments, NAT IPs, or Load Balancer paths. - IPAddressAllocation: add allocationIPs and validation: introduces allocationIPs field with validation to require either allocationSize or allocationIPs (not both) and enforces immutability after being set. - DTGW/CTGW pathing alignment and diagnostics: aligns DTGW/CTGW pathing with edge cluster path, deprecates the service cluster path for DTGW; improves readiness detection via distributed VLAN attachments and enhances error reporting for diagnostics. - Subnet management enhancements: shared subnets, path centralization, and robustness: centralizes subnet path utilities, supports SubnetPort on shared Subnets, guards against nil Subnet CRs, and avoids unnecessary DHCP IP/MAC updates on IP changes. Business value: reduced provisioning time, stronger IP governance, and more reliable multi-tenant networking with improved observability. Technologies/skills demonstrated: Go-based operator patterns, Kubernetes CRD reconciliation, path utilities, validation, and enhanced diagnostics.
