And I think many of them could be useful for other +people installing servers. They are already available on our svn server, +but I think we can do something better, to make them easier to use. + +When trying to use puppet modules from other people that I found on the +internet, I usually have the following problems : + - modules are made for other distributions + - modules have dependencies on other modules, and it is not easy to see + which ones + - sometimes they can have dependency on an other module doing something + that you already do with a different module (for instance there is many + different apache httpd modules) + - modules come from unknow people, so you have to check them carefully + before using them + - you need to modify them to do what you want, because there often is + a lot of hardcoded values everywhere + +So I think it could be interesting to provide some modules for Mageia, +and distribute them as packages, doing the same as what we do for other +software. + +We could do something like this : + - one package per module + - modules installed in /usr/share/puppet/modules + - use rpm find-requires and find-provides to automatically manage + dependencies between modules + - remove any hardcoded values from modules, but use parameterised + classes, so you don't have to modify modules to use them + - setup puppet so that someone who wants to overwrite a module installed + by a package can create one with the same name in /etc/puppet/modules. + Or overwrite one template file. + +Then people using Mageia will be able to install puppet modules that +are known to work with Mageia. + +For instance, someone who wants to install a wordpress blog with a mysql +database on a second server could do something like this very quickly : + +# urpmi puppet-wordpress puppet-mysql +# cat > /etc/puppet/manifests/site.pp <<EOF +node server1 { + class { mysql::server: + dbtype => "innodb" + } + class { mysql::dbuser: + dbuser => 'wordpress', + dbpassword => 'password', + } +} +node server2 { + class { wordpress: + hostname => 'blog.example.com', + dbtype => 'mysql', + dbhost => 'server1.example.com', + dbuser => 'wordpress', + dbpassword => 'password', + } +} +EOF + +Or someone who wants to setup a Mageia buildsystem to build his own +packages : +# urpmi puppet-mgabuildsystem +# cat > /etc/puppet/manifests/site.pp <<EOF +node mainnode { + class { mgabuildsystem::mainnode: + distribname => "My Distribution", + domain => "mydistribution.org", + ... + } +} +... +EOF + +Those module could also be used locally by some tools. For instance if +we want to create a graphical tool like drakwizard, to setup some software +on a machine. This graphical interface would ask some parameters, then +install the corresponding puppet modules, generate a puppet file +containing the parameters entered and run puppet on it locally. + +However compared to what we do currently : + - it will be more work, to avoid hardcoding anything + - modules can become more complexe if they support more things + - we will have to be careful when changing API of released modules, or + write it in release notes so users of the packages know what they need + to change when updating to a newer release of the distribution. + +So it is more work, but I think it can be worth it. We can maybe convince +other Mageia packagers to help write puppet modules for the software +they package. + +A distribution providing puppet modules for many software would allow +someone to install one or many servers very quickly and easily, and I +think it would be very nice. + +Maybe this is something that could be done for Mageia release 2 or later. +So I plan to try to see if/how this could be done. + +What do you think ? + +</PRE> + + + + + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="003190.html">[Mageia-sysadm] Some work to do on tx +</A></li> + <LI>Next message: <A HREF="003192.html">[Mageia-sysadm] Packaging puppet modules +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#3191">[ date ]</a> + <a href="thread.html#3191">[ thread ]</a> + <a href="subject.html#3191">[ subject ]</a> + <a href="author.html#3191">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-sysadm">More information about the Mageia-sysadm +mailing list</a><br> +</body></html> |
