What is Kaniko?

Kaniko's release feed stops dead in June 2024 after a patch that undid its own change

Kaniko builds container images inside a container without a Docker daemon, and its release feed reads as a project in late-stage maintenance that then simply stopped. Every entry in this window carries the same boilerplate header of executor, debug and slim image tags, and underneath it the substance is dependency bumps, CVE-driven upgrades, and narrow fixes to ADD and COPY semantics. The last release here, v1.23.1, is a revert of behaviour changed weeks earlier plus documentation clarifying what the flag was supposed to do.

What is Skipper?

Skipper adds RFC 9421 HTTP Message Signatures and delivers 21% RouteGroup load time improvement

Skipper v0.27 is shipping at a steady maintenance cadence with two functional additions of note: v0.27.96 adds native RFC 9421 HTTP Message Signatures filter support — a 2023 IETF standard for request signing gaining traction in financial services and regulated APIs. v0.27.95 delivers a shared parse cache across RouteGroups, producing a measured 21% load time reduction, 12% lower memory, and 26% fewer allocations on a 200-RouteGroup benchmark.

Kaniko's release feed stops dead in June 2024 after a patch that undid its own change

◆ Current state

Kaniko builds container images inside a container without a Docker daemon, and its release feed reads as a project in late-stage maintenance that then simply stopped. Every entry in this window carries the same boilerplate header of executor, debug and slim image tags, and underneath it the substance is dependency bumps, CVE-driven upgrades, and narrow fixes to ADD and COPY semantics. The last release here, v1.23.1, is a revert of behaviour changed weeks earlier plus documentation clarifying what the flag was supposed to do.

◆ Where it's heading

The cadence tells the story: nine releases between December 2023 and June 2024, then nothing at all in the two years since. Even during the active stretch the work was defensive — registry-map compatibility, ECR authentication breakage, tar.gz handling in ADD, vulnerability scanning added to the executor image — rather than any expansion of what Kaniko does. The one recurring theme with forward motion, registry mirror and registry-map support, was about surviving locked-down or mirrored registry environments.

◆ Prediction

Nothing in these entries points at planned work, and a two-year gap after a revert-and-document patch is the signature of a project no longer being released; anyone depending on it should assume the last published executor image is the last one.

Skipper adds RFC 9421 HTTP Message Signatures and delivers 21% RouteGroup load time improvement

◆ Current state

Skipper v0.27 is shipping at a steady maintenance cadence with two functional additions of note: v0.27.96 adds native RFC 9421 HTTP Message Signatures filter support — a 2023 IETF standard for request signing gaining traction in financial services and regulated APIs. v0.27.95 delivers a shared parse cache across RouteGroups, producing a measured 21% load time reduction, 12% lower memory, and 26% fewer allocations on a 200-RouteGroup benchmark.

◆ Where it's heading

Skipper is building out its security posture at the proxy layer: RFC 9421 request signing, Redis L2 cache (v0.27.92), and security header handling improvements (v0.27.88) suggest a consistent push toward production-grade security primitives without architectural breaks. The performance improvements in v0.27.95 address real-world Kubernetes clusters where large RouteGroup counts are common.

◆ Prediction

RFC 9421 support will likely get expanded configuration options — signing key rotation, policy enforcement modes, per-route key selection — as Zalando's internal adopters surface operational requirements for the filter.
