Description

Hello,

I have a crontab like this :

@reboot root /directories/script.sh &> /dev/null

But I can't use @reboot at the line frequency, I have this message when I save:

The form contains some errors, please correct them.
Please modify Manually defined frequency to match the requested format : Please enter a valid cron interval

@reboot is a reserved words for crons
Could you help me to solve this problem ?

Thks a lot

tested with rudder-server 3.2.4 on ubuntu 14.04

It might be worth mentioning, that there are also other special prefixes as of man 5 crontab:

@reboot    :    Run once, at startup.
@yearly    :    Run once a year, ie.  "0 0 1 1 *".
@annually  :    Run once a year, ie.  "0 0 1 1 *".
@monthly   :    Run once a month, ie. "0 0 1 * *".
@weekly    :    Run once a week, ie.  "0 0 * * 0".
@daily     :    Run once a day, ie.   "0 0 * * *".
@hourly    :    Run once an hour, ie. "0 * * * *".

Hello

is it possible to add manually special prefixes into technique (file) "Cron daemon configuration version 3.0" ?

Target version changed from 3.2.6 to 2.11.24

Thanks for the report Jérémy.

The allowed strings are defined by a (rather long) regex in https://github.com/Normation/rudder-techniques/blob/master/techniques/systemSettings/systemManagement/cronManagement/3.0/metadata.xml#L95. That same file is on Rudder servers under /var/rudder/configuration-repository/techniques/...

If you can patch the regex to accept those strings, you have a workaround. If you can a patch submitted via GitHub pull request would be most welcome!

I tried to
edit /opt/rudder/share/techniques/systemSettings/systemManagement/cronManagement/3.0/metadata.xml
restart server services
create new directive

and I don't see my modifications

is it somewhere else ?

No, that's the correct location, but this is a git repository. After making changes you need to git add <file> && git commit -m "Useful message here". Then run "rudder server reload-techniques" (or click on "Reload techniques" in the web interface under Settings)

Oh, sorry, wait. No, that is not the right location. That is the distribution standard copy of Techniques. Please don't ever edit them.

The correction location is the one I gave above, under /var/rudder/configuration-repository/techniques/...

Tanks Jonathan,

I edited metadata.xml into /var/rudder/configuration-repository/techniques/systemSettings/systemManagement/cronManagement/3.0 to add a new item (into diff file)
I presume just add a item can make me use predefined value for special prefixes
but i was mistaken

I can modify regex but this is not really what i want to do, I think add item may be a more efficient solution (and '''chronophage-less''' frenglish inside :þ)

It works perfectly
I created a new technique 3.1 with .diff file

user@machine:/var/rudder/configuration-repository/techniques/systemSettings/systemManagement/cronManagement# git add 3.1/
user@machine:/var/rudder/configuration-repository/techniques/systemSettings/systemManagement/cronManagement# git commit -a -m "Add reboot into cronManagement technique (3.1)"
[master 6732a6d] Add reboot into cronManagement technique (3.1)
