Puppet fails to ensure file is present

I am using the following configuration in a module. It only has to ensure the file sysctl.conf is present in /etc folder. But it doesn't do that.

class sysctl::config{
  file{ "/etc/sysctl.conf":
    ensure   => present,
    owner    => 'root',
    group    => 'root',
    mode     => '0644',
    source   => 'puppet:///modules/sysctl/sysctl.conf',

I use a similar configuration for other files like sshd_config, sources.list, etc in their respective modules, and all they work.

Furthermore when I check the puppet report it seems all occurred correctly despite the file not being present.

File[/etc/sysctl.conf]: !ruby/object:Puppet::Resource::Status
      resource: File[/etc/sysctl.conf]
      file: /etc/puppet/modules/sysctl/manifests/config.pp

      failed: false
        - Stage[main]
        - "Sysctl::Config"
        - File[/etc/sysctl.conf]

What am I missing?

You're specifying the file's `source` attribute, but it never gets considered since `ensure => present` (= `touch <filename>`). See https://docs.puppetlabs.com/puppet/latest/reference/types/file.html#file-attribute-ensure for details.

Kai's correct, you want ensure => file if you plan on using a source. ensure => present is more for, ensuring the file exists but doing nothing with it. Combined with audit, this can be useful. It also ensures a file that is normally manually modified, exists at least ...

That is not true. If you specify `ensure => present` the ensure property will be considered insync if it is a file OR a directory (instead of `ensure=>file` or `ensure=>directory`). However this should not ignore the source property and wether the source is in sync..

Do you see any error messages? Is sysctl empty? Is the puppet able to read the source file? What happens if you modify `/etc/sysctl` locally?

are you sure you are looking at the correct server? If you edit the file puppet:///modules/sysctl/sysctl.conf and run puppet, is the Puppet report different than the one in your post?
