badger

badger

Badger is a lightweight alternative to systemd, it runs your scripts and manages your daemons at startup.

Features

• Live reload of the daemons file allows your to add and remove daemons and scripts while system is running live
• Automatically restarts failed daemons and stops removed daemons
• Offers a simple replacement for an otherwise heavy init daemon like systemd.
• Designed to be used with runc, systemd and serve as systemd replacement in docker containers
• Properly reaps zombies
• Follows KISS principle

initFile

s:/runMeOnce.sh param1
d:/iAmDaemon.sh
d:/usr/sbin/sshd -D

Running

Using inplace of /sbin/init

badger can be used inplace of /sbin/init, for example when using microvms. In those cases as no arguments are passed it will read config from /initrc and write log to init.log

Shell

./badger if /initFile log /log/badger.log

runC

Place badger in /bin/badger inside container/rootfs/bin/badger and create the container/rootfs/initFile and log folder. runC config.json example:

	"args": [
		"/bin/badger if /initFile log /log/badger.log"
	],

systemD

Using badger to start your services on startup Add contents to /etc/systemd/system/badger.service
