I am seeing the following error...
Error: Evaluation Error: Unknown variable: 'osfamily'. (file: /etc/puppetlabs/code/environments/production/manifests/print_text.pp, line: 1, column: 4) on node mgmtserver.mydomain.com
...when attempting to run a manifest on the Puppet Server...
puppet apply /etc/puppetlabs/code/environments/production/manifests/print_text.pp
The manifest is:
if $osfamily == 'RedHat' {
notice("A test message")
}
The following returns results...
puppet facts osfamily
{
"osfamily": "RedHat"
}
...as does the following:
facter osfamily
RedHat
The Puppet Server is:
puppetserver.service (master) is running on the host but puppet.service (agent) is not.
Any suggestions?
If you are attempting to resolve a fact, then you would need to access the fact's value. The syntax $osfamily would instead attempt to resolve a value assigned to the variable osfamily which is undefined in your accessible scope. This can be accomplished with the following syntax:
if $facts['os']['family'] == 'RedHat' {
notice("A test message")
}
Note the documentation also contains this as an example.
