file: square bracket in template

[Laurent CREPET]

Hi,

I'm new to Puppet. I'm using Puppet 3.4.3. I'm trying tried to build a template of file /etc/my.cnf. Puppet does not like the square brackets in my.cnf.erb, giving the following error:

    Error: Parameter source failed on File[/etc/my.cnf]: Could not understand source [mysqld]

I will have a look at the Puppet Forge for modules to deal with MySQL. However, can we have a square bracket in a template (outside of the "Out-of-Scope Variables" use) ?

Regards,

Laurent.

To the best of my knowledge, square brackets appearing in ERB template text have no special meaning to ERB.  They are just copied verbatim to the output.

I suspect that you have written something like

file { '/etc/my.cnf'':
  source => template('my.cnf.erb')
}

where what you want is

file { '/etc/my.cnf'':
  content => template('my.cnf.erb')
}

The distinction is quite important: the 'source' parameter is expected to specify a URL from which the agent get retrieve the desired file content, whereas the 'content' property gives the content itself.  (The two are mutually exclusive.)

You're right about the fact that I've used "source" instead of "content" !

Thanks for your help.
