How to create a directory with date and time stamp in a puppet manifest. I am on Unix OS. I tried couple of things but couldnt able to capture the current date and time in a variable.

example: exec {"newdir": command => "mkdir -p /tmp/foo/foobardate_time"

}

With Puppet you define the state of the system. If you tell puppet "I want to have a directory with the current time stamp in it" this will be impossible to achieve because your desired state actually changes from second to second.

Why do you need that directory? What is your goal?

Just for reference: You can use the generate function to execute arbitrary shell code

$timestamp = generate('/bin/date', '+%Y%d%m_%H:%M:%S')

file { "/tmp/foo_${timestamp}":
  ensure => directory,
}

but this will add directories on every puppet run.

Thanks for the response. I want to create couple of file in datestamped directory. Like this: $wrkdir = "/tmp/aafoo/foobar" $timestamp = generate('/bin/date', '+%Y%d%m')

exec {"newdir" : command => "mkdir -p $wrkdir/new${timestamp}", path => ["/usr/bin/"], before => File["$wrkdir/new_${timestamp}/switch.xml"], }

file {"$wrkdir/new${timestamp}/switch.xml": ensure => present, require => Exec["newdir"], }

file {"$wrkdir/new${timestamp}/datafile.xml": ensure => present, require => Exec["newdir"], }

But I am getting this error: sudo puppet apply file_manifest.pp

Error: Could not set 'present' on ensure: No such file or directory - /tmp/aafoo/foobar/new20132603 /switch.xml ... (more)

It looks like puppet was not able to create the file because the parent directory was not there. I suspect that generate returns the date output with a nasty newline ...(more)

It still smells like you are trying to do something with puppet that puppet really is not designed for so a bit more details about why you need the directory ...(more)

As Stefan alluded, Puppet will not recursively create directories. You must explicitly create the directories, or specify your dirs as an array.
