Hi,
After upgrading openproductionource Puppet to version 4.9, I followed
the Hiera guide
https://docs.puppet.com/puppet/4.9/hiera_hierarchy.html#most-hierarchies-interpolate-variables
<https://docs.puppet.com/puppet/4.9/hiera_hierarchy.html#most-hierarchies-interpolate-variables>
to feed some data to it. I found that for some node, 'puppet lookup' failed to
interpolate variables in yaml setting, which lead to incorrect lookup results.
Any suggestion is welcome.
Best,
Jianwen
Steps to reproduce this issue
1. Install Puppet server on puppet.
<http://puppet.sjtu.edu.cn/>pi.sjtu.edu.cn .
2. Install Puppet agents on puppet.pi.sjtu.edu.cn
<http://puppet.pi.sjtu.edu.cn/>, slurm1.pi.sjtu.edu.cn
<http://slurm1.pi.sjtu.edu.cn/> and mu05.pi.sjtu.edu
<http://mu05.pi.sjtu.edu/>.cn. Sign certificates for them.
3. Delete global hiera setting `/etc/puppetlabs/code/hiera.yaml`.
# rm -f /etc/puppetlabs/code/hiera.yaml
4. Create an environment named `production`.
# mkdir -p
/etc/puppetlabs/code/environments/production/{hieradata,maifests,modules}
5. Create the Hiera conf file for the production environment in
`/etc/puppetlabs/code/environments/production/hiera.yaml`
---
version: 5
defaults:
datadir: hieradata
data_hash: yaml_data
hierarchy:
- name: "Per-node data"
path: "nodes/%{trusted.certname}.yaml"
- name: "common"
path: "common.yaml"
6. Add common data in
`/etc/puppetlabs/code/environments/production/hieradata/common.yaml`:
---
group: Compute Nodes
7a. Add per-node hiera data for slurm1.pi.sjtu.edu.cn in
`/etc/puppetlabs/code/environments/production/hieradata/nodes/slurm1.pi.sjtu.edu.cn.yaml`:
---
group: SLURM
7b. Add per-node hiera data for puppet.pi.sjtu.edu.cn in
`/etc/puppetlabs/code/environments/production/hieradata/nodes/puppet.pi.sjtu.edu.cn.yaml`:
---
group: Puppet Server
8a. Lookup group for puppet.pi.sjtu.edu.cn and successfully get
"Puppet Server" stored in `puppet.pi.sjtu.edu.cn
<http://puppet.pi.sjtu.edu.cn/>.yaml`.
# puppet lookup group --node puppet.pi.sjtu.edu.cn --explain

8c. Lookup group for puppet.pi.sjtu.edu.cn and fail to
interpolate %{trusted.certname} which results in incorrect lookup fallback to
`common.yaml`. It is expected to use `slurm1.pi.sjtu.edu.cn
<http://slurm1.pi.sjtu.edu.cn/>.yaml` instead thus the correct result should be
"SLURM", not "Compute Nodes".
