It then launches the runtime as its child. This allows +managing processes to die in the foreground, but still be able to watch over +and connect to the child process (the container). + +While the container runs, conmon does two things: + + Provides a socket for attaching to the container, holding open the + container's standard streams and forwarding them over the socket. Writes + the contents of the container's streams to a log file (or to the systemd + journal) so they can be read after the container's death. + +Finally, upon the containers death, conmon will record its exit time and code +to be read by the managing programs. + +Written in C and designed to have a low memory footprint, conmon is intended +to be run by a container managing library. Essentially, conmon is the smallest +daemon a container can have. diff --git a/system/conmon/conmon.SlackBuild b/system/conmon/conmon.SlackBuild new file mode 100644 index 000000000000..cca924bf78f6 --- /dev/null +++ b/system/conmon/conmon.SlackBuild @@ -0,0 +1,98 @@ +#!/bin/sh + +# Slackware build script for conmon + +# Copyright 2019 Gabriel Diaz, Madrid, Spain +# Copyright 2019 Vincent Batts, Raleigh, NC, USA +# All rights reserved. +# +# Redistribution and use of this script, with or without modification, is +# permitted provided that the following conditions are met: +# +# 1.
