Its niche is not launching a whole container stack, but sitting between a container manager such as Podman or CRI-O and an OCI runtime such as runc or crun. ### Project history The upstream README describes conmon as an OCI container runtime monitor and communication tool. It double-forks, starts the OCI runtime as its child, keeps standard streams attachable, writes logs, and records exit status for the higher-level manager. The project is maintained under the containers GitHub organization, the same ecosystem that hosts Podman-adjacent container tooling. Its design goal is deliberately narrow: the README calls it the smallest daemon a container can have. ### Adoption history conmon became distribution-visible because Podman and CRI-O need a separate monitor that can outlive the foreground manager. The README says it should usually be packaged with the user's container manager, and the input package metadata lists it across Homebrew, apk, Debian, Ubuntu, Fedora/dnf, Nix, pacman, and zypper. ### How it is used Most users do not run conmon directly. It is installed as support infrastructure for Podman, CRI-O, and other OCI-container workflows, where it keeps container attach sockets, logging, and exit reporting separate from the manager process. ### Why package nerds care conmon is a useful package-manager specimen because it exposes a normally hidden layer of the container stack as its own shippable binary. Packaging it correctly matters for Podman and CRI-O behavior, especially install paths such as libexec locations used by those managers. ### Timeline - 2019: GitHub releases include early 0.x and 2.0.x conmon releases. - 2026: Input package metadata lists conmon in major Linux and macOS package managers. ### Related projects - Podman and CRI-O are the container managers named by the README. - runc and crun are the OCI runtimes named by the README. ### Sources - - ## Security Notes generalized runtime or code generation signal. infrastructure mutation or orchestration signal. - **Geiger risk:** orange / medium - generalized runtime or code generation signal - infrastructure mutation or orchestration signal ## Other Package-Manager Records - Debian apt - conmon - 2.1.12-4: normalized package name match | Debian stable package indexes: conmon from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | OCI container runtime monitor | https://github.com/containers/conmon - Debian apt - golang-github-containers-conmon-dev - 2.1.12-4: normalized package name match | Debian stable package indexes: golang-github-containers-conmon-dev from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | OCI container runtime monitor | https://github.com/containers/conmon - Nix - conmon: normalized package name match | nixpkgs package indexes: pkgs/by-name/co/conmon/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - conmon - 2.1.10+ds1-1build2: normalized package name match | Ubuntu 24.04 LTS package indexes: conmon from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | OCI container runtime monitor | https://github.com/containers/conmon - Ubuntu apt - golang-github-containers-conmon-dev - 2.1.10+ds1-1build2: normalized package name match | Ubuntu 24.04 LTS package indexes: golang-github-containers-conmon-dev from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | OCI container runtime monitor | https://github.com/containers/conmon - apk - conmon - 2.2.1-r0: normalized package name match | Alpine Linux edge package indexes: conmon from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | OCI container runtime monitor | https://github.com/containers/conmon - apk - conmon-doc - 2.2.1-r0: normalized package name match | Alpine Linux edge package indexes: conmon-doc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | OCI container runtime monitor (documentation) | https://github.com/containers/conmon - dnf - conmon - 2.2.1-2.fc45: normalized package name match | Fedora Rawhide package metadata: conmon from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-primary.xml.zst | OCI container runtime monitor | https://github.com/containers/conmon - pacman - conmon - 1:2.2.1-1: normalized package name match | Arch Linux sync databases: conmon from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | OCI container runtime monitor | https://github.com/containers/conmon - zypper - conmon - 2.2.1-1.5: normalized package name match | openSUSE Tumbleweed package metadata: conmon from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | An OCI container runtime monitor | https://github.com/containers/conmon ## Combined YAML source View the package source record on GitHub.
