What is HAProxy Kubernetes Ingress Controller?

Nine months into the 3.2 line, HAProxy Ingress is still repairing ssl-passthrough and ingress merge order.

The controller ships a steady patch cadence on the 3.2 branch, roughly one release every two to four weeks. Content is almost entirely correctness work: ssl-passthrough handling and the rules that decide which Ingress object owns a shared backend. Feature additions are absent from the last ten releases; dependency bumps to k8s.io and golang.org/x packages appear in most of them.

What is Tailscale?

Tailscale is turning the tailnet itself into something a script provisions and pages through.

Two threads run in this window. The client and operator releases are maintenance-grade — a Funnel regression fix, library-only container updates, Kubernetes operator work on PeerRelays, workload identity federation and IPv6 egress. The more consequential thread is the tailnet management API: creation landed in alpha at the end of July, and the list endpoint has now been paginated, with a hard 100-result default for organizations holding more.

HAProxy Kubernetes Ingress Controller vs Tailscale: editorial side-by-side

H2.5

Nine months into the 3.2 line, HAProxy Ingress is still repairing ssl-passthrough and ingress merge order.

◆ Current state

The controller ships a steady patch cadence on the 3.2 branch, roughly one release every two to four weeks. Content is almost entirely correctness work: ssl-passthrough handling and the rules that decide which Ingress object owns a shared backend. Feature additions are absent from the last ten releases; dependency bumps to k8s.io and golang.org/x packages appear in most of them.

◆ Where it's heading

v3.2.13 is the largest release in the window and marks a shift from patching individual ssl-passthrough bugs to defining the semantics properly: backends are now reconciled rather than recreated, the invariant is applied before anything that can fail, and controller-owned backend state survives a failed transaction. Alongside it, ingress merge order became deterministic — oldest ingress first — and the first Ingress to constitute a backend now owns it, with the annotations a losing Ingress forfeits named explicitly. That pairing suggests the team traced a class of flapping and non-reproducible config bugs back to undefined ordering.

◆ Prediction

Expect the next few releases to stay on the 3.2 patch line, adding tests around the new ownership and passthrough invariants rather than new annotations.

Tailscale is turning the tailnet itself into something a script provisions and pages through.

◆ Current state

Two threads run in this window. The client and operator releases are maintenance-grade — a Funnel regression fix, library-only container updates, Kubernetes operator work on PeerRelays, workload identity federation and IPv6 egress. The more consequential thread is the tailnet management API: creation landed in alpha at the end of July, and the list endpoint has now been paginated, with a hard 100-result default for organizations holding more.

◆ Where it's heading

Tailscale has spent this period on two different customers at once. The operator work serves platform teams running Tailscale inside Kubernetes, where the gaps being closed are reconciliation loops, stale DNS ConfigMaps and cert-renewal backoff. The tailnet API work serves a different shape entirely: organizations holding enough tailnets that a hundred is a page boundary, which only happens when tailnets are allocated per customer or per environment rather than per company. The second thread is the one that changes what Tailscale is for.

◆ Prediction

Pagination on list implies the creation API is being used at volume, so expect the alpha to gain the management operations a fleet needs — policy templating or bulk configuration across tailnets. The client release line looks settled on 1.102.x maintenance in the near term.
