What is HAProxy Kubernetes Ingress Controller?

Fourteen patches into 3.2, and ssl-passthrough is still where the bugs are.

The controller is deep in the 3.2 patch line, shipping roughly every two weeks with no new configuration surface since the series opened. Four of the last six releases touch ssl-passthrough: resolving its mode before rules are built, reconciling its backends, and now keeping allow and deny lists attached to the https frontend. The rest is Kubernetes-object correctness — EndpointSlice handling, ingress merge ordering, duplicated backend config snippets.

What is Skipper?

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.

Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

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

H5.0

Fourteen patches into 3.2, and ssl-passthrough is still where the bugs are.

◆ Current state

The controller is deep in the 3.2 patch line, shipping roughly every two weeks with no new configuration surface since the series opened. Four of the last six releases touch ssl-passthrough: resolving its mode before rules are built, reconciling its backends, and now keeping allow and deny lists attached to the https frontend. The rest is Kubernetes-object correctness — EndpointSlice handling, ingress merge ordering, duplicated backend config snippets.

◆ Where it's heading

This is a stabilisation series, not a feature series. The recurring theme is that ssl-passthrough interacts badly with everything layered on top of it — access control, backend reconciliation, rule generation — and each release fixes one more intersection. Test coverage is now landing alongside the fixes rather than after them, which suggests the maintainers are treating the passthrough path as a known weak spot rather than a series of unrelated bugs.

◆ Prediction

Expect 3.2.x to continue at a two-week cadence with further ssl-passthrough intersections, and expect any new capability to wait for a 3.3 line rather than arrive in a patch.

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.

◆ Current state

Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

◆ Where it's heading

The Redis L2 integration suggests the Skipper team is addressing the multi-replica cache coherence problem that large deployments encounter. If this pattern continues, distributed-state options—persistent rate limiting, distributed circuit breakers using the same Redis client abstraction—are the natural follow-ons. The high patch cadence signals active production deployment rather than feature-driven development.

◆ Prediction

The Redis client abstraction introduced in v0.27.92 will be extended to other stateful filters, particularly rate limiting, given that distributed rate limiting is the most common request for API gateways running at multi-replica scale.
