Reading Environment processing in fact Variables in Puppet

Reading Environment processing in fact Variables in Puppet - An unlocked phone is one which is not tied to any particular mobile operator, such as Vodafone or EE. Buying unlocked usually means buying the phone outright without a SIM. The most important point is that an unlocked phone is almost always a better deal than buying a phone on contract. especially when you include, well we have collected a lot of data from the field directly and from many other blogs so very complete his discussion here about Reading Environment processing in fact Variables in Puppet, on this blog we also have to provide the latest automotive information from all the brands associated with the automobile. ok please continue reading:

Puppet uses a tool called Facter to discover facts about the system it is going to provision. Some examples of these facts are: $operatingsystem, $hostname, $processorcount, etc. These facts are available as variables in puppet to use in manifests. You can see the full list here: Factor 2.0 Core Facts.

If you want an environment variable, or a bash script parameter to be available to puppet, you need to make it available as a Facter fact. You can do that by simply setting a variable whose name is prefixed with the "FACTER_" string.

So for instance, if you wanted to make a variable called say $my_module_name available within puppet, and wanted its value to be equal to environment variable PRODUCT_MODULE_NAME, you could do the following in a bash script that invokes puppet:

export FACTER_my_module_name=$PRODUCT_MODULE_NAME

Now, $my_module_name variable will be available within your puppet manifests.

Setting a Default if Environment Variable is not set

To take this further, if you wanted your puppet variable to have a default value, if no environment variable was set, you could specify it in puppet manifest (.pp) file like this:

$module_name = $my_module_name ? {
      undef => "Admin_Module",
      default               => $my_module_name 
}

Note that the above code uses a different variable name called "module_name", whose value will be set to "Admin_Module" if $my_module_name is un-defined, else it will be set to value of "my_module_name" variable.
Now you can use $module_name in all your puppet manifests (instead of using $my_module_name).

To see a sample code where I did this in Bahmni Hospital Management System provisioning scripts, check out this Github commit: Example.

Tip: If you wish to debug what facts are being set in your system, you can use this snippet to print all facts to a file: Printing all puppet facts.

Tip: If your puppet script is running with "sudo", then the environment variables set in current environment won't be passed to the sudo environment. If you want that, then use "-E" switch with sudo to pass environment variables forward.
