Curator: how to escape characters of "--timestring" in systemd?


(Fbarbeira) #1

I tried to set up a task in systemd but I'm not able to escape the characters used in the parameter "--timestring". For example:

docker run user/curator --host x.x.x.x --port 9200 --dry-run delete indices --older-than 5 --time-unit days --timestring %Y.%m.%d

If I execute the previous command on the command line it works fine but when I tried to include it in a systemd timer task it failed with the following message:

I tried to escape that characters using:

$ systemd-escape %Y.%m.%d
\x25Y.\x25m.\x25d
$

But it fails with the same message. Somebody knows how to execute that curator line in a systemd timer task??

I stumbled over the same issue today on CoreOs.
I found that a single percent is escaped as '%%'.
Things will work if you write:

--timestring '%%Y.%%m.%%d'

(from http://www.freedesktop.org/software/systemd/man/systemd.unit.html)

Cheers,

Thanks for this! I will add it as a FAQ to the Curator documentation!
