I’ve been using Puppet here and there for about a year now. \u00a0In the last six month, I went rather heavy, and managed to accumulate quite a bit of modules, configs, hosts, etc. \u00a0Refactoring some of the code, and trying out new ideas, I’m reading through the Beginner’s Guide to Modules<\/a> to help me with the best practices. \u00a0A couple of bits from there, I think, are worth quoting:<\/p>\n

(Tip: If you describe the function of your module and you find yourself using the word \u2018and\u2019, it\u2019s time to split the module at the \u2018and\u2019<\/em>.)<\/p><\/blockquote>\n

This above is useful to people like me, who got comfortable throwing bits and pieces into modules, but don’t quite know yet where is that thin line for the module separation. \u00a0The above tip makes that crystal clear. \u00a0So, for example, “my module installs and configures something” no becomes two modules, where one “installs something” and another “configures something”.<\/p>\n

It is standard practice for Puppet users to have upwards of 200 modules in their environment.<\/p><\/blockquote>\n

With this I know that my current setup is rather small and simplistic. \u00a0It’s not the numbers I am after, of course. \u00a0But, again, it’s difficult to say if I am doing too much of it, or not enough; if the system has been built to scale to the level where I am. \u00a0It turns out, \u00a0I have a long way to go. \u00a0A quick check shows that I’m at 127 modules in my current setup. \u00a0And that one is used for configuring pretty much everything – base installs, web \/ db \/ dev servers, desktops, etc.<\/p>\n

Some of it will get expanded as I am replacing quite a bit of my own modules with third-party ones. \u00a0Interestingly enough, I wasn’t comfortable using other people’s code in the beginning and wanted things to be precisely my way (there were some time constraints). \u00a0It worked well, for a time. \u00a0But not a lot of it can be thrown away and replaced with other people’s code. \u00a0More features and less maintenance for the win!<\/p>\n\n","protected":false},"excerpt":{"rendered":"\n
