Write data: Set per-node data

The highest level of the example hierarchy uses the value of $trusted['certname'] to locate its data file, so you can set data by name for each individual node.

This example supposes you have a server named jenkins-prod-03.example.com, and configures it to use SSL and to serve this application at the hostname ci.example.com. To try this out, choose the name of a real server that you can run Puppet on.

  1. To locate the data file, replace %{trusted.certname}with the node name you’re targeting:

    /etc/puppetlabs/code/environments/production/data/ + nodes/ + jenkins-prod-03.example.com + .yaml

  2. Open that file in an editor and add the following contents: 

    # /etc/puppetlabs/code/environments/production/data/nodes/jenkins-prod-03.example.com.yaml
---
profile::hiera_test::ssl: true
profile::hiera_test::site_alias: ci.example.com

  3. Compile to observe that the override takes effect.
