What is HAProxy Kubernetes Ingress Controller?

Nineteen patches into 3.2, HAProxy's ingress controller is mostly bumping dependencies

The controller remains on the 3.2 patch line. Since v3.2.14 the only release of substance is v3.2.15, which stopped filtering ingresses on IngressClass name at ingestion, reworked status publishing and moved to Go 1.27. Later patches are mainly dependency and tooling updates, with v3.2.18 keeping every TLS secret of an ingress on the same host and v3.2.19 fixing a data race on the reload flag.

What is runc?

runc 1.6.0-rc.1 lifts the 1024-CPU limit and refuses settings it used to quietly ignore

The 1.6.0 cycle opened on October 6 with a first release candidate that is mostly cleanup: deprecated libcontainer APIs removed, Go 1.26 now required, urfave/cli moved from v1 to v3, and the binary about 15% smaller on amd64. The changes with operational weight are that cpuAffinity and NUMA memoryPolicy no longer stop at 1024 CPUs or nodes, and that a container asking for a read-only rootfs without its own mount namespace is now refused. Eleven days earlier 1.5.2 worked around a kernel bug, present since v6.17, that corrupted memory inside runc and caused random crashes on cgroup v2. It also stopped runc exec --cgroup from escaping into a sibling cgroup.

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

H5.0

Nineteen patches into 3.2, HAProxy's ingress controller is mostly bumping dependencies

◆ Current state

The controller remains on the 3.2 patch line. Since v3.2.14 the only release of substance is v3.2.15, which stopped filtering ingresses on IngressClass name at ingestion, reworked status publishing and moved to Go 1.27. Later patches are mainly dependency and tooling updates, with v3.2.18 keeping every TLS secret of an ingress on the same host and v3.2.19 fixing a data race on the reload flag.

◆ Where it's heading

The ssl-passthrough theme has faded, and the series is now closer to routine upkeep than stabilization. Fixes have moved to ingress class handling, TLS secret storage and concurrency, with test coverage arriving in the same changes. Patches keep coming, but no new configuration surface has appeared on this line in the entries shown, apart from amending the SSL frontend through a custom resource in v3.2.15.

◆ Prediction

Expect further patches dominated by go.mod and Kubernetes client updates, with new capability waiting for a later line.

runc 1.6.0-rc.1 lifts the 1024-CPU limit and refuses settings it used to quietly ignore

◆ Current state

The 1.6.0 cycle opened on October 6 with a first release candidate that is mostly cleanup: deprecated libcontainer APIs removed, Go 1.26 now required, urfave/cli moved from v1 to v3, and the binary about 15% smaller on amd64. The changes with operational weight are that cpuAffinity and NUMA memoryPolicy no longer stop at 1024 CPUs or nodes, and that a container asking for a read-only rootfs without its own mount namespace is now refused. Eleven days earlier 1.5.2 worked around a kernel bug, present since v6.17, that corrupted memory inside runc and caused random crashes on cgroup v2. It also stopped runc exec --cgroup from escaping into a sibling cgroup.

◆ Where it's heading

The project keeps converting silent behaviour into explicit behaviour. Read-only requests that were ignored now fail, a umask that was dropped is now honoured, and poststart hooks moved to conform to the runtime spec. The same maintainers are shrinking the surface underneath, dropping the deprecated API and the high-level cilium/ebpf path, which took roughly 7.5% off the 1.5.2 binary. Stricter behaviour plus a smaller dependency set is what a component under every container host would be expected to do between majors.

◆ Prediction

1.5.0's notes pointed to a 1.6.0 in late October 2026, and the feed so far shows only rc.1, so further release candidates or the final are the next entries to expect. The refused read-only configurations are the change most likely to surface as user reports during testing.
