Has anyone got any neat solutions for Asterisk .conf file revision
control?
We have multiple Asterisk boxes here, that we'd like to maintain a
_mostly_ common set of conf files on. They aren't all the same
though. There's subtle differences. For example, in sip.conf,
iax.conf etc, the bindaddr setting is different. Dundi.conf is very
different between each system.
At the moment I have a file tree on a separate server, and I use
the m4 processor to replace certain unique sections of the files. I
have a bunch of scripts to build sip.conf etc and then rsync the
files out to the servers. It works, mostly, but it isn't elegant.
I'd like to revision control all this. I don't know how it could be
done with revision control though. As I said, not all the files are
the same. I don't know if we'd run a version control client on each
Asterisk box, or if we'd run it centrally, and then use rsync
again, to copy the files out.
Here are some general rules we apply to this sort of config/
distribution/version-control set up
across multiple non-identical servers
(Mostly learnt in the web-server world, but it applies generally I
think)
1) Never check in derived files. Only check in the _inputs_ to M4,
never the outputs.
2) do the 'localization' (ie server specific config) on the target
server itself, ideally
automatically - never depend on user input - get the server to tell
the install script what
it needs to know.
3) don't user rsync unless all the files are identical
so you might have
checkitallout.sh
(use appropriate svn stuff - I'm a cvs user, so can't help there)
then a script that customizes and installs the files as needed,
with likes like:
cpp -Dhost=`uname -n` -Darch=`uname -m` iax.conf.generic /etc/
asterisk/iax.conf
or even
cpp -I`uname -n` iax.conf.generic /etc/asterisk/iax.conf
with
#include "iax.conf.local"
in iax.conf.generic and subdirectories for each host with their own
iax.conf.local
Good luck.
