gkunwar / yggdrasil

ruby script to manage server configurations by subversion.

Yggdrasil

Yggdrasil is a subversion wrapper to manage server configurations and conditions.

Installation

$ gem install yggdrasil

subversion needs to be installed:

(e.g.)$ sudo yum install subversion

Usage: private use(stand alone)

Prepare subversion repository and initialize Yggdrasil:

$ ygg init --repo private

You should use svn-server if you have. In that case, the configuration files of all the servers can be managed on the unification.

Add configuration files to manage:

$ ygg add /etc/hosts /etc/fstab   ..etc
$ ygg check
$ ygg commit /

Check modify and/or delete:

$ vi /etc/hosts ..etc
$ ygg check
$ ygg commit /etc/hosts ..etc

Refer Help:

$ ygg help

Usage: data center management (example)

Prepare subversion repository and launch server on host:$YGG_SERVER:

(e.g. $YGG_REPO is anywhere you want)
$ svnadmin create $YGG_REPO
$ vi $YGG_REPO/conf/svnserve.conf
$ svnserve -d

Prepare yggdrasil server on host:$YGG_SERVER:

$ yggserve init --repo svn://$YGG_SERVER/$YGG_REPO/{host} --port 4000
$ yggserve daemon

Prepare yggdrasil client to manage config files:

$ ygg init --server $YGG_SERVER:4000
$ ls -al ~/.yggdrasil/checker
and add/modify executable script in "checker"
$ ygg add /etc/hosts /etc/fstab ..etc
$ ygg check
$ ygg commit /

Prepare yggdrasil client to report check results to yggdrasil server, every day:

$ crontab -e
add following line(you should check path by 'which ygg')
17 5 * * * $GEMPATH/ygg check --non-interactive

Check updates of configurations/conditions on host:$YGG_SERVER:

$ yggserve results --expire 1440
CI tool(e.g.Jenkins) may execute this command automatically to daily report/record.

Environment

• Linux
