Dokku vs Robusta: 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 Robusta?
Robusta's recent releases patch its runner image rather than add features.
Robusta ships from an alpha channel, so alpha tags are its release line. The October tags are almost entirely image and CI work: 0.52.0-alpha patched high and critical CVEs in the runner image and removed orphaned Perl packages after a Debian upgrade, 0.52.0-alpha.1 backported OpenSSH, curl, expat and systemd fixes from Debian forky, and 0.54.0-alpha's notes cover only the removal of helm golden-file tests from CI. The last feature work in the feed was August's workflow trigger action and the signing-key leak fix.
Dokku vs Robusta: editorial side-by-side
Dokku
5.0INFRA · APIS
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.
Robusta
5.0INFRA · APIS
Robusta's recent releases patch its runner image rather than add features.
◆ Current state
Robusta ships from an alpha channel, so alpha tags are its release line. The October tags are almost entirely image and CI work: 0.52.0-alpha patched high and critical CVEs in the runner image and removed orphaned Perl packages after a Debian upgrade, 0.52.0-alpha.1 backported OpenSSH, curl, expat and systemd fixes from Debian forky, and 0.54.0-alpha's notes cover only the removal of helm golden-file tests from CI. The last feature work in the feed was August's workflow trigger action and the signing-key leak fix.
◆ Where it's heading
Since late August the project has been treating its container image as the product surface that needs attention, with CVE patching handled by backporting packages from the next Debian release. The feature line that added workflow chaining, JSON logs and new alert sources has gone quiet in these entries. The 0.53 tag does not appear in the feed, so part of the picture may be missing.
◆ Prediction
Expect more runner-image CVE releases on the alpha line. Whether feature work on Holmes integration or alert sources resumes is not visible in these entries.
