[Puppet Users] Using Puppet for downgrading Varnish (circular dependency)
Hi all,
I am trying to use puppet (2.7.18) for downgrading varnish cache on Centos
Linux (6.3).
Unfortunately there are two varnish RPMs (which seem to have circular
dependencies):
varnish-3.0.4-1.el6.x86_64
varnish-libs-3.0.4-1.el6.x86_64
When using "ensure" for downgrading I get a bunch of errors:
err: /Stage[main]/Varnish/Package[varnish-libs]/ensure: change from
3.0.4-1.el6 to 3.0.3-1.el6 failed: Could not update: Execution of
''/usr/bin/yum -d 0 -e 0 -y downgrade varnish-libs-3.0.3-1.el6''
returned 1:
Error: Package: varnish-3.0.4-1.el6.x86_64 (@varnish-3.0)
Requires: varnish-libs = 3.0.4-1.el6
Removing: varnish-libs-3.0.4-1.el6.x86_64 (@varnish-3.0)
varnish-libs = 3.0.4-1.el6
Downgraded By: varnish-libs-3.0.3-1.el6.x86_64 (varnish-3.0)
varnish-libs = 3.0.3-1.el6
Available: varnish-libs-2.1.5-1.el6.i686 (EPEL-RHEL)
varnish-libs = 2.1.5-1.el6
Available: varnish-libs-3.0.3-0.rc1.el6.x86_64 (varnish-3.0)
varnish-libs = 3.0.3-0.rc1.el6
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
at /etc/puppet/environments/development/modules/varnish/manifests/init.pp:8
err: /Stage[main]/Varnish/Package[varnish]/ensure: change from 3.0.4-1.el6
to 3.0.3-1.el6 failed: Could not update: Execution of ''/usr/bin/yum -d
0 -e
0 -y downgrade varnish-3.0.3-1.el6'' returned 1: Error: Package:
varnish-3.0.3-1.el6.x86_64 (varnish-3.0)
Requires: varnish-libs = 3.0.3-1.el6
Installed: varnish-libs-3.0.4-1.el6.x86_64 (@varnish-3.0)
varnish-libs = 3.0.4-1.el6
Available: varnish-libs-2.1.5-1.el6.i686 (EPEL-RHEL)
varnish-libs = 2.1.5-1.el6
Available: varnish-libs-3.0.3-0.rc1.el6.x86_64 (varnish-3.0)
varnish-libs = 3.0.3-0.rc1.el6
Available: varnish-libs-3.0.3-1.el6.x86_64 (varnish-3.0)
varnish-libs = 3.0.3-1.el6
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
at /etc/puppet/environments/development/modules/varnish/manifests/init.pp:8
Whatever I try I do not succeed. My goal is to have a rock-solid puppet
manifest for switching between varnish versions in development environments
without having to reinstall the whole VM.
Using yum to downgrade both packages at the same time (and being able to
resolve circular dependencies) succeeds:
/usr/bin/yum -d 0 -e 0 -y downgrade varnish-libs-3.0.3-1.el6
varnish-3.0.3-1.el6
Any idea how I can solve this?
Kind regards,
Stefan

Re: [Puppet Users] Using Puppet for downgrading Varnish (circular dependency)
Hi Stefan,
I''ve run into similar issues before… I don''t have module code
handy, but
what I ended up doing was creating an exec which performed something
similar to:
exec{''nuke_pesky_pkg'':
command => ''rpm -e $package; touch /etc/package.removed'',
creates => ''/etc/package.removed''
}
which I run before the package declaration..
I imagine others might have better suggestions?

Re: [Puppet Users] Using Puppet for downgrading Varnish (circular dependency)
Hi Wolf, indeed that ''exec'' solution is what I''ve found when searching for a solution. In my situation this won''t help - unfortunately. Nevertheless I tracked down the main problem to be caused by different usage scenarios for yum. When upgrading I have to specify only the main varnish package ''varnish''. When downgrading I have to specify both the ''varnish'' and the ''varnish-libs'' package for yum. As long as puppet does not support both options we will have to use work- arounds. ;-) Stefan -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Re: [Puppet Users] Using Puppet for downgrading Varnish (circular dependency)
