[Puppet Users] newly added ruby function executes on the server instead of the node
Hi,
1) I added this test function tom my
/etc/puppet/modules/write_line_to_file/lib/puppet/parser/functions/write_line_to_file.rb
:
*module Puppet::Parser::Functions newfunction(:write_line_to_file) do |args|
filename = args[0]
str = args[1]
File.open(args[0], ''a'') {|fd| fd.puts str }
end
end*
2) I invoked it in the
/etc/puppet/modules/write_line_to_file/manifest/init.pp like this:
*class write_line_to_file{
write_line_to_file(''/tmp/some_file'', "Hello world!")
}*
3) And I also included this module into my /etc/puppet/manifests/nodes.pp
under the correct node:
*node default {}
node ''testnode.domain.com''
{
include hosts
include uninstall_screen
include write_line_to_file
}*
*
*The function does execute, but on the puppetmaster - not on the remote
node. Other two functions execute on the correct node. What am I missing?
Thank you!
Vicki

What am I missing?Functions run on puppet master, facts and resource provider run on puppet agent. Writing functions won''t allow you to change puppet agent files (unless you clone module and run puppet apply). If you are trying to write line to a file either use augeas type or puppet file_line from stdlib: http://forge.puppetlabs.com/puppetlabs/stdlib HTH, Nan -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

It''s a half-decent way of puppetizing an arbitrary number of files at once.> HTH, > > Nan > > -- > You received this message because you are subscribed to the Google Groups "Puppet Users" group. > To post to this group, send email to puppet-users@googlegroups.com. > To unsubscribe from this group, send email to puppet-users+unsubscribe@googlegroups.com. > For more options, visit this group at http://groups.google.com/group/puppet-users?hl=en. > >-- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Thank you for the quick reply! This explains the the behavior I see.
