What is Dokku?

Dokku is quietly turning into a k3s front-end with a JSON-first CLI.

The 0.38 patch line keeps shipping small releases with real features in them. v0.38.27 drops the local-image requirement for k3s deploys, reports Traefik DNS-provider variables as global keys, adds storage directory mode and removal flags, and introduces a vector-cron-sink so scheduled cron output has somewhere to go. It follows v0.38.26, which brought wildcard domains, custom cert issuers, and kernel sysctls to the k3s scheduler.

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.

Dokku is quietly turning into a k3s front-end with a JSON-first CLI.

◆ Current state

The 0.38 patch line keeps shipping small releases with real features in them. v0.38.27 drops the local-image requirement for k3s deploys, reports Traefik DNS-provider variables as global keys, adds storage directory mode and removal flags, and introduces a vector-cron-sink so scheduled cron output has somewhere to go. It follows v0.38.26, which brought wildcard domains, custom cert issuers, and kernel sysctls to the k3s scheduler.

◆ Where it's heading

Two threads run through almost every release: closing the gap between the k3s scheduler and the classic single-host path, and making every command machine-readable. The k3s work has moved from basic scheduling to the operational details — certificates, DNS, sysctls, and now deploys that no longer assume a local Docker image — which is the sequence a project follows when it expects the Kubernetes path to become the default rather than the alternative.

◆ Prediction

Expect the remaining k3s parity gaps to keep closing one release at a time, and expect the logging work started with vector-cron-sink to extend to other task types that currently have no sink.

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.
