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 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.

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.

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.
