What is Inspektor Gadget?

Inspektor Gadget v0.56 adds Kubernetes multi-tenancy and GPU telemetry groundwork

Inspektor Gadget is expanding from a cluster-admin debugging tool toward a multi-tenant eBPF observability platform. v0.56 ships Kubernetes multi-tenancy (experimental), authenticating gadget requests via TokenReview and scoping them to namespaces authorized by RBAC — the first time the tool can be deployed safely in shared clusters without granting cluster-wide access. v0.55 laid GPU observability groundwork with a userspace daemon publishing telemetry through pinned BPF maps, and expanded eBPF program type support (SockOps, SkSKB, SkMsg).

What is werf?

werf ships weekly across two tracks — v3 dev gets JSON Schemas and Harbor v2 fixes, v2 alpha gets the backports.

werf operates two active release channels in parallel: v3.x ("dev") for new capabilities and v2.x ("alpha") for stabilized backports. The September 2026 sprint covers v3.3–v3.5 and v2.78–v2.79, with several meaningful improvements — JSON Schema publication for werf config files, a netavark networking requirement replacing CNI/slirp4netns, and a Harbor registry fix that clears a real registry-compatibility issue. The dual-track cadence lets teams stay on the stable alpha channel while the dev track absorbs the larger changes.

Inspektor Gadget v0.56 adds Kubernetes multi-tenancy and GPU telemetry groundwork

◆ Current state

Inspektor Gadget is expanding from a cluster-admin debugging tool toward a multi-tenant eBPF observability platform. v0.56 ships Kubernetes multi-tenancy (experimental), authenticating gadget requests via TokenReview and scoping them to namespaces authorized by RBAC — the first time the tool can be deployed safely in shared clusters without granting cluster-wide access. v0.55 laid GPU observability groundwork with a userspace daemon publishing telemetry through pinned BPF maps, and expanded eBPF program type support (SockOps, SkSKB, SkMsg).

◆ Where it's heading

Inspektor Gadget is building toward production-grade eBPF observability that can operate safely in multi-tenant Kubernetes environments without requiring cluster-admin. The RBAC-scoped multi-tenancy in v0.56, combined with rootless image commands and stripped Go binary uprobes (which now work on production kubelets), shows a team deliberately removing the prerequisites that blocked enterprise adoption. GPU telemetry is early-stage but positions the tool for AI workload observability before competitors have native eBPF coverage there.

◆ Prediction

The Kubernetes multi-tenancy mode will graduate from experimental to stable in the next 1-2 releases as the SubjectAccessReview enforcement path gets broader testing. GPU telemetry will gain actual gadget consumers once the bridge daemon interface stabilizes.

5.0

werf ships weekly across two tracks — v3 dev gets JSON Schemas and Harbor v2 fixes, v2 alpha gets the backports.

◆ Current state

werf operates two active release channels in parallel: v3.x ("dev") for new capabilities and v2.x ("alpha") for stabilized backports. The September 2026 sprint covers v3.3–v3.5 and v2.78–v2.79, with several meaningful improvements — JSON Schema publication for werf config files, a netavark networking requirement replacing CNI/slirp4netns, and a Harbor registry fix that clears a real registry-compatibility issue. The dual-track cadence lets teams stay on the stable alpha channel while the dev track absorbs the larger changes.

◆ Where it's heading

werf's dev track is progressively expanding its deploy primitives: renderPatches support, returning rendered resources from ReleaseInstall, and authenticated secret write capability (v3.3.0) all suggest a push toward more programmable, auditable deploy pipelines. The embedded Deno binary in v3.2.0 — bundled behind a feature gate — hints at scripted deployment hooks as a coming capability. JSON Schemas for werf config files make editor tooling a first-class citizen.

◆ Prediction

The Deno embedding will likely surface as a supported scripting API for pre/post-deploy hooks in the next major dev release. A corresponding migration of Helm-centric users toward werf's native deploy primitives appears to be the longer arc.
