Class 如何根据另一个类的状态编写puppet类依赖关系

我有两个类叫做

main.pp

和

precheck.pp

。我的想法是main.pp将继续执行，如果

precheck.pp

成功。那么，我应该如何获得

precheck.pp

class my::main {
   require my::module::precheck
   # I want to execute installpackage if precheck is succeed.
   require my::module::installpackage
}

class my::module::precheck {
       if $facts['osfamily'] == 'redhat' {
        if versioncmp($facts['operatingsystemmajrelease'], '7') >= 0 {
            notify {"osrelease":
                message => "${::operatingsystemmajrelease} is good to install myapp."
            }
        }
        else {
            fail("myapp is not supported on this OS release")
        }
    }
    else {
         fail("myapp is not supported on ${::osfamily}.")
    }
} 

在

precheck.pp

class my::main {
   require my::module::precheck
   # I want to execute installpackage if precheck is succeed.
   require my::module::installpackage
}

class my::module::precheck {
       if $facts['osfamily'] == 'redhat' {
        if versioncmp($facts['operatingsystemmajrelease'], '7') >= 0 {
            notify {"osrelease":
                message => "${::operatingsystemmajrelease} is good to install myapp."
            }
        }
        else {
            fail("myapp is not supported on this OS release")
        }
    }
    else {
         fail("myapp is not supported on ${::osfamily}.")
    }
} 

上述代码段未按预期工作

您可以使用以下工具创建类级依赖项：

这将在

precheck

类容器上为

installpackage

类容器创建依赖项。请注意，与类容器结合使用的类级依赖通常不被认为是最佳实践
