Hi all,
I just recently started using CFEngine 3 and was wondering what the best
practice for constructing system configuration files (e.g., /etc/resolv.conf)
is. Right now I am just adding and deleting lines from the file, but it seems
to execute with every run of cf-execd. On the other hand, I am pulling down a
global /etc/passwd file from the server, and that seems to execute much more
efficiently since it only gets copied when I make changes to that. Any
suggestions would be greatly appreciated!
Also, here is the bundle I am currently trying to execute. The delete_lines
doesn't seem to work, but that is probably my fault and I will just look
further into it.
bundle agent resolv_file
{
vars:
"resolv_fields" slist => {"search <search domains>","nameserver
<ip>","nameserver <ip>","nameserver <ip>"};
files:
"/etc/resolv.conf"
edit_line => DeleteLinesMatching("^nameserver.*"),
edit_line => addline($(resolv_fields));
}
bundle edit_line DeleteLinesMatching(regex)
{
delete_lines:
"$(regex)";
}
bundle edit_line addline(resolvList)
{
insert_lines:
"$(resolvList)";
}
Thanks,
Scott
