Puppet users - Feb 2013 - Why a "execute" command show as "changed" on Dashboard?

Hello,

I''m using the puppet-dashboard-1.2.10 and I''ve noticed that I
have too much
"Changed" hosts, but this is not true. This is only hosts running
"exec"
commands, like:

    notice 
>     executed successfully 
>     /Stage[main]/Executecron/Exec[crontab_backup]/returns 
>     /etc/puppet/manifests/crontab.pp

Which is some like this:

    command => "/usr/bin/crontab -l >
/movile/crontab/root_$hostname.txt",


So, why this happen? Can I avoid this?

Thanks!!

You are creating a ''new'' file every time(well new content), so
in essence,
it is true that the configuration has changed.

To avoid this, you should make your command smarter and make sure it only 
runs when changes are in the crontab. There is no need to make a backup of 
something that has not changed.

It would probably be even better to just manage the file itself in puppet, 
giving you complete control over it, and not needing a backup anymore.

Also, creating backups by using puppet is not really good practise. Puppet 
is good at setting up a configuration, and should be about resources coming 
to a defined state, not about being a job scheduler. 

In short, there is no ''normal'' way around abnormal use of
Puppet ;) But of
course workarounds are possible.

Hello Danny, nice explanation, thank you!!!

I agree with you, this is really a "new" file everytime. So
let''s try
another example:

exec { "authconfig":
>             command => "authconfig-tui --ldapserver=ldap://ldap.com
> --ldapbasedn=dc=bla,dc=com --enableshadow --enablemd5 --enableldap 
> --enableldapauth --disableldaptls --enablelocauthorize --kickstart",
>             path    => "/usr/bin/:/bin/:/usr/sbin",
>             onlyif  => "fgrep ldap.com /etc/ldap.conf",
>         }

The idea is the same: Just do the configuration if was needed, but when I 
look the report, I got:

Log
LevelMessageSourceFileLineTimenoticeexecuted successfully
/Stage[main]/Base::Ldap/Exec[authconfig]/returns
/etc/puppet/modules/base/manifests/ldap.pp362013-02-14 10:38 BRSTnoticeFinished 
catalog run in 7.56 secondsPuppet2013-02-14 10:38 BRST

What can I do to workaround this? :D

Thanks!!

The message means that the authconfig-tui command is run *every time* 
puppet runs. This does not seem to be your intention. I guess, you 
should write "unless => [ldap is configured]" instead of
"onlyif =>
[ldap is configured]"
