HAProxy Kubernetes Ingress Controller vs Inspektor Gadget: at a glance
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 Inspektor Gadget?
Inspektor Gadget keeps cutting the privileges an eBPF tool has to ask for.
Inspektor Gadget v0.57.0 lets gadgets run rootless with cap_bpf, cap_perfmon and cap_sys_ptrace, and adds a flag that drops CAP_SYS_ADMIN on Kubernetes deployments. v0.56.0 introduced experimental multi-tenancy through TokenReview and RBAC. The v0.56.1 and v0.56.2 patches backported USDT parsing fixes, so crafted binaries cannot crash the process or exhaust memory, and bounded owner reference enrichment.

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.

2.5INFRA · APIS
Inspektor Gadget keeps cutting the privileges an eBPF tool has to ask for.
◆ Current state
Inspektor Gadget v0.57.0 lets gadgets run rootless with cap_bpf, cap_perfmon and cap_sys_ptrace, and adds a flag that drops CAP_SYS_ADMIN on Kubernetes deployments. v0.56.0 introduced experimental multi-tenancy through TokenReview and RBAC. The v0.56.1 and v0.56.2 patches backported USDT parsing fixes, so crafted binaries cannot crash the process or exhaust memory, and bounded owner reference enrichment.
◆ Where it's heading
The direction is lower trust: fewer privileges for the tool and less trust in the binaries it inspects. Multi-tenancy, rootless runs and hardened ELF parsing all remove reasons a security team would refuse to deploy it. GPU telemetry from v0.55 has no follow-up in the recent notes.
◆ Prediction
Multi-tenancy graduating from experimental remains the likely next milestone as it pairs with reduced-privilege deployments. Whether GPU telemetry gets gadget consumers soon is unclear from these entries.
