Add line to file for one node

We have an existing puppet setup that is working well. However, on one node, I want to append a line to a configuration file. How do I do that?

The file is currently fully defined in a manifest. The .pp file includes a file { ... } paragraph with a 'content' attribute that is good for all the other hosts. I have a node/name.yaml file for the node on which I want to append one more line to the file. How do I specify that in the .yaml file? Alternatively, how may I override the entire file {...} paragraph in the .yaml file?

More info is necessary. Please update your question with the actual file resource in question and your hiera setup.

I would recommend taking your module/manifest/template able to take a parameter, that is only defined for the node in question. If you try to do something 'funny' like using a file_line resource, you are going to get thrashing between the file and file_line

It would help to specify the Puppet version and Hiera configuration you are using.

If you have different levels configured in Hiera you may be able to rely on automatic parameter lookup to set 'content' for each host.

Make $content a variable in the .pp file Set the common host string at a high level like Common/Location/Role/OS. Set the host specific content in the FQDN file. Set content => $content,

That's the simplest and most common way to handle that configuration.
