Dokku vs Inspektor Gadget: at a glance
What is Dokku?
Dokku's autumn patches swap new features for safer deploys and stricter validation.
The 0.38 line reached v0.38.34 in late October, and the recent releases are mostly about correctness. Deploy locks now release on exit and honor apps:lock, app names and arguments are validated across commands, config write failures are reported, and dokku run propagates exit codes. Smaller additions include a --no-cache flag for ps:rebuild, per-entry cron MAILTO and a configurable nginx proxy HTTP version.
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.

Dokku's autumn patches swap new features for safer deploys and stricter validation.
◆ Current state
The 0.38 line reached v0.38.34 in late October, and the recent releases are mostly about correctness. Deploy locks now release on exit and honor apps:lock, app names and arguments are validated across commands, config write failures are reported, and dokku run propagates exit codes. Smaller additions include a --no-cache flag for ps:rebuild, per-entry cron MAILTO and a configurable nginx proxy HTTP version.
◆ Where it's heading
The August k3s parity push has given way to a hardening pass through commands that used to fail quietly. A second thread makes configuration declarative: storage mounts, scheduler-k3s metadata and chart overrides each gained a whole-set form, which suits automation tools more than people at a terminal. Machine use of the CLI remains the through-line.
◆ Prediction
Expect the whole-set form to reach more properties, since three subsystems have now gained it. Patch releases should stay frequent, and the notes give no sign of a move past the 0.38 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.
