replace variable value on ruby template via puppet

Question

I am looking the way to have the result of this ruby template file:

ServerName 1.server.foo

knowing that if I run

$ facter -p fqdn
1.server.foo.internet.com

I would probably play with <%= @fqdn %> and .gsub?

server-id: <%= @fqdn %>.gsub(/.internet.com/, '')

oobs. seems not working well . `server-id: 01.server.foo.internet.com.gsub(/\.internet.comt/b/, '')` — nerabis, Feb 25 '20 at 13:56

The entire expression needs to be in the <%= %> tag, so try

server-id: <%= @fqdn.regsubst(/.internet.com/, '') %>

The template syntax is documented at https://puppet.com/docs/puppet/5.5/lang_template_erb.html with examples of expressions used in <%= %> tags.

I'd also note that ERB templates have been replaced by native Embedded Puppet EPP templates, so it may be better to convert now.

am trying with EPP. `server-id: <%= $facts[fqdn].gsub(/.internet.com/, '') %>;` but, he do not like. Unknown function: 'gsub' – nerabis Feb 25 '20 at 17:29

using EPP with regsubst it works!

server-id: <%= $facts[fqdn].regsubst(/.internet.com/, '') %>

I've shamelessly updated my answer to use this, the correct function! – Jon Feb 26 '20 at 13:10
