Conmon is the container monitor. It is a small +program whose job is to watch the primary process of the container, and if the +container dies, save the exit code. It also holds open the tty of the +container, so that it can be attached to later. This is what allows Podman to +run in detached mode (backgrounded), so Podman can exit but conmon continues to +run. Each container has their own instance of conmon. Conmon waits for the +container to exit, gathers and saves the exit code, and then launches a Podman +process to complete the container cleanup, by shutting down the network and +storage. For more information on conmon, please reference the conmon(8) man +page. + ## FILES **/etc/subuid** @@ -1427,7 +1441,7 @@ NOTE: Use the environment variable `TMPDIR` to change the temporary storage loca ## SEE ALSO **podman**(1), **podman-secret**(1), **podman-save**(1), **podman-ps**(1), **podman-attach**(1), **podman-pod-create**(1), **podman-port**(1), **podman-start*(1), **podman-kill**(1), **podman-stop**(1), -**podman-generate-systemd**(1) **podman-rm**(1), **subgid**(5), **subuid**(5), **containers.conf**(5), **systemd.unit**(5), **setsebool**(8), **slirp4netns**(1), **fuse-overlayfs**(1), **proc**(5)**. +**podman-generate-systemd**(1) **podman-rm**(1), **subgid**(5), **subuid**(5), **containers.conf**(5), **systemd.unit**(5), **setsebool**(8), **slirp4netns**(1), **fuse-overlayfs**(1), **proc**(5), **conmon**(8). ## HISTORY October 2017, converted from Docker documentation to Podman by Dan Walsh for Podman `<dwalsh@redhat.com>` |
