Hi,
I'm assessing Cfengine 3 (community edition) to manage a bunch of
servers. It seems to have all the required features but I can't
figure out how to manage packages (at least in the way I want).
I believe package management is quite new in Cfengine 3 so what I
need may not exist yet.
I'd like to be able to list explicitely what packages has to be
installed on each server. This is easy:
bundle agent packages
{
vars:
"match_package" slist => { "pkg1" , "pkg2" } ;
packages:
"$(match_package)"
package_policy => "add" ,
package_method => generic ;
}
But I also want other packages to be removed. Ideally, packages
installed as dependencies of those listed in $(match_package)
should be handled automatically so they don't have to be listed
explicitely but it depends heavily on which package manager is
used. So, supposing every required package (and their
dependencies) is listed in $(match_package), how can I have any
other one removed?
Intuitively, I'd like to be able to add something like that to my
bundle:
packages:
not "$(match_package)"
package_policy => "delete" ,
package_method => generic ;
But I haven't found the right syntax to use (I may have missed
something in the documentation, as it's quite hard for a
newcomer).
Is there a way to do that?
