It became widely known because it solves the PID 1 problem in Docker-style containers: reaping zombie processes and forwarding signals while staying transparent to the application. ### Project history Tini's README defines the project in intentionally minimal terms: it spawns one child process, waits for it to exit, reaps zombies, and forwards signals. That narrow scope is the project's identity; it is not a process supervisor, service manager, or orchestration layer. The first visible tag in the official repository is v0.1.0 in 2015, and the release stream continued through v0.19.0 in 2020. Over that period the README grew into a container-packaging guide: download a signed binary, verify checksums, add it as an ENTRYPOINT, or install it from a distribution package. ### Adoption history Tini's adoption story is unusually strong for a tiny utility because Docker incorporated it. The README states that Docker 1.13 and later include Tini and enable it with docker run --init; Docker's own prior release notes describe the --init flag as using Tini as a zombie-reaping PID 1. The README also documents Alpine Linux, NixOS, Debian, and Arch packaging, plus prebuilt Docker images. The supplied package-manager facts add Homebrew, Fedora/dnf, Ubuntu, and zypper, showing that package managers treat Tini as a standalone utility even after Docker embedded it. ### How it is used The common manual use is to install a Tini binary into a container image and set ENTRYPOINT to run Tini before the real application. Tini then handles signal forwarding and child reaping, preserving application behavior while making container shutdown and cleanup more predictable. Operators can also use options for subreaping when Tini is not PID 1, exit-code remapping for cases such as SIGTERM exit 143, and process-group killing for shell wrappers or child process trees. ### Why package nerds care Tini is package-nerd catnip because it is almost the smallest possible program that became infrastructure. It turned a subtle Linux/container semantic problem into a single binary that distros, Docker images, and Docker itself could depend on. Its packaging story also shows how a tool can move from GitHub release asset, to distro package, to embedded runtime component, while still remaining useful as an explicit package for users outside Docker's default path. ### Timeline - 2015: v0.1.0 appears in the official repository tag history. - 2017: Docker 1.13 added --init support using Tini as a zombie-reaping PID 1. - 2018: The project published v0.18.0. - 2020: The project published v0.19.0, the current release shown by the official GitHub release list inspected for this batch. ### Related projects - Docker is the most important downstream adopter; Docker 1.13 integrated Tini behind the --init flag. - dumb-init occupies a similar container-init niche. - Linux subreaper behavior is part of Tini's option model when it cannot run as PID 1. ### Sources -
