Beyond Traditional VPNs: WireGuard Mesh Networking for Kubernetes with Tailscale
summary
WireGuard mesh replaces hub-and-spoke VPNs here by exposing Kubernetes services with a single annotation: the Tailscale Operator registers services and tailscale expose: true adds DNS and HTTPS via a load balancer class: tailscale. A connector pod advertises subnet routes to external managed resources (e.g., ElastiCache) and policies live as code in the infra repo. SCIM-driven revocation shows up in ~10 minutes, audit trails and SSO group-based access are enforced, and the setup largely removes prior VPN complaints.
