dockerfiler vs rush: at a glance
What is dockerfiler?
dockerfiler's 1.0.0 changes what its generated Dockerfiles actually contain.
After two years of small parameter additions, ThinkR shipped a 1.0.0 that changes the tool's output for every existing user. The vendored copy of renv is gone, generated images default to multi-arch rocker/r-ver running as a non-root rstudio user, and packages come from Posit Public Package Manager binaries instead of a source CRAN mirror.
What is rush?
Rush spent 2026 making distributed task ownership correct, starting with a breaking 1.0.
rush is the Redis-backed distributed computing backend behind mlr3's parallel tuning: workers pull tasks, push results and are tracked through heartbeats. Since 1.0.0 in March 2026 it has shipped five releases in four months, almost all correcting how tasks and workers are owned and identified under failure. The most recent lets each worker start in its own mirai call so it can spawn local daemons.

dockerfiler's 1.0.0 changes what its generated Dockerfiles actually contain.
◆ Current state
After two years of small parameter additions, ThinkR shipped a 1.0.0 that changes the tool's output for every existing user. The vendored copy of renv is gone, generated images default to multi-arch rocker/r-ver running as a non-root rstudio user, and packages come from Posit Public Package Manager binaries instead of a source CRAN mirror.
◆ Where it's heading
The package is being hardened rather than extended. Every user-supplied value that reaches a Dockerfile shell context is validated at function entry, and two long-standing code-injection paths — a crafted renv.lock version string and DCF continuation lines in DESCRIPTION fields — were closed after an internal audit. The new parameters point at production image builds: github_pat via BuildKit secret mounts, strict_install turning install warnings into build failures, and a configurable renv cache path.
◆ Prediction
With the injection surface closed and the defaults flipped, the next releases are more likely to be compatibility work against renv and pak than new generators.
rush
2.5INFRA · APIS
Rush spent 2026 making distributed task ownership correct, starting with a breaking 1.0.
◆ Current state
rush is the Redis-backed distributed computing backend behind mlr3's parallel tuning: workers pull tasks, push results and are tracked through heartbeats. Since 1.0.0 in March 2026 it has shipped five releases in four months, almost all correcting how tasks and workers are owned and identified under failure. The most recent lets each worker start in its own mirai call so it can spawn local daemons.
◆ Where it's heading
The through-line is moving responsibility from the controller to the worker. 1.0.0 rewrote the task lifecycle and dropped the seed mechanism; 1.2.0 moved fail_tasks(), finish_tasks(), pop_task() and push_running_tasks() from Rush onto RushWorker so only the worker that ran a task can mark it done, and gave worker ids random suffixes so they cannot collide. 1.1.0 had already removed phantom failed tasks when a worker crashes between evaluations.
◆ Prediction
With ownership and identity settled, the remaining pressure points are heartbeat and lost-worker detection; expect the next releases to tighten failure recovery rather than add API surface.
