我在将 Hiera 3 与 Puppet 4.2 一起使用时遇到了一些问题。使用此命令应用我的木偶清单时:
puppet apply environments/production/manifests/init.pp --hiera_config=hiera.yaml
我收到以下错误:
Error: Evaluation Error: Error while evaluating a Function Call, Could not find data item myclass::ensure in any Hiera data file and no default supplied at /home/vagrant/temp/environments/production/manifests/init.pp:13:39 on node a
这是目录结构:
$ tree
.
├── environments
│ └── production
│ ├── config.yaml
│ └── manifests
│ └── init.pp
└── hiera.yaml
config.yaml 的内容:
$ cat hiera.yaml
---
:backends:
- yaml
:hierarchy:
- config
:yaml:
:datadir: environments/production
init.pp 的内容:
class myclass(
$version = $myclass::params::version,
$ensure = $myclass::params::ensure,
) inherits myclass::params {
notify {"$version": }
notify {"$ensure": }
}
class myclass::params {
$version = hiera('myclass::version', '1.0.0')
$ensure = hiera('myclass::ensure', 'running')
}
class {'myclass': }
hiera数据源内容:
$ cat config.yaml
---
myclass::version: '1.0.0'
myclass::ensure:
看起来 Hiera 无法处理来自 yaml 数据源的空值和/或用默认值替换它们?
