【问题描述】：
我在使用 Puppet 和 Hiera 时遇到了一些问题，因为 Hiera 似乎没有使用我在模板中要求的事实。
我有一个/etc/puppetlabs/puppet/hiera.yaml 文件，其中包含一个简单的示例层次结构：
---
version: 5
defaults:
datadir: "/etc/puppetlabs/code/environments/%{::environment}/hieradata"
data_hash: yaml_data
hierarchy:
- name: "Per-node data"
path: "nodes/%{trusted.certname}.yaml"
- name: "Per-OS defaults"
path: "os/%{facts.os.family}.yaml"
- name: "Common data"
path: "common.yaml"
然后我有一个 puppet 代理，它已经运行并将它的事实发送给 Puppet。当我测试它的查找时，变量都扩展为空字符串：
> puppet lookup profiles --environment production --node puppet.example.local --explain
Searching for "lookup_options"
Global Data Provider (hiera configuration version 5)
Using configuration "/etc/puppetlabs/puppet/hiera.yaml"
Merge strategy hash
Hierarchy entry "Per-node data"
Path "/etc/puppetlabs/code/environments/production/hieradata/nodes/test-.yaml"
Original path: "nodes/test-%{trusted.certname}.yaml"
Path not found
Hierarchy entry "Per-OS defaults"
Path "/etc/puppetlabs/code/environments/production/hieradata/os/.yaml"
Original path: "os/%{facts.os.family}.yaml"
Path not found
Hierarchy entry "Common data"
Path "/etc/puppetlabs/code/environments/production/hieradata/common.yaml"
Original path: "common.yaml"
No such key: "lookup_options"
Searching for "profiles"
Global Data Provider (hiera configuration version 5)
Using configuration "/etc/puppetlabs/puppet/hiera.yaml"
Hierarchy entry "Per-node data"
Path "/etc/puppetlabs/code/environments/production/hieradata/nodes/.yaml"
Original path: "nodes/test-%{trusted.certname}.yaml"
Path not found
Hierarchy entry "Per-OS defaults"
Path "/etc/puppetlabs/code/environments/production/hieradata/os/.yaml"
Original path: "os/%{facts.os.family}.yaml"
Path not found
Hierarchy entry "Common data"
Path "/etc/puppetlabs/code/environments/production/hieradata/common.yaml"
Original path: "common.yaml"
No such key: "profiles"
Function lookup() did not find a value for the name 'profiles'
未找到该值，但我认为这无关紧要，因为它甚至没有寻找任何真实文件，这些文件都显示为 nodes/.yaml 和 os/.yaml。
如果我再次使用--debug 运行命令，我可以看到包含事实的节点信息转储：
Debug: Facter: fact "osfamily" has resolved to "RedHat".
...
Debug: Facter: fact "os" has resolved to {
architecture => "x86_64",
family => "RedHat",
hardware => "x86_64",
name => "CentOS",
release => {
full => "7.4.1708",
major => "7",
minor => "4"
},
傀儡：5.4.0
【问题讨论】：
-
这是Facter 3.x？
-
@MattSchuchard
facter --version说 3.10.0。 -
您没有在命令行上指定任何事实。
puppet lookup命令将获取并使用指定节点的最新事实如果它们记录在 puppetdb 中并且该命令在有权访问的节点上运行。它不会像puppet agent或puppet apply那样自动收集事实。
