If you have global classes, and you want to have a bundle that can act based on
any of those classes, you could also use ifvarclass, something like this:
body common control {
version => "1.0.0";
bundlesequence => { "g", "main" };
}
bundle common g
{
classes:
"one" expression => "any";
}
bundle agent main
{
methods:
"any" usebundle => foo("one");
"any" usebundle => foo("two");
"any" usebundle => foo("three");
}
bundle agent foo(classarg)
{
reports:
cfengine::
# The decision is made based on the class whose name was passed as an argument
"Class '$(classarg)' is defined"
ifvarclass => "$(classarg)";
"Class '$(classarg)' is not defined"
ifvarclass => "!$(classarg)";
}
When run:
$ /var/cfengine/bin/cf-agent -KI -f ./test.cf
R: Class 'one' is defined
R: Class 'two' is not defined
R: Class 'three' is not defined
