How to configure puppet so that it installs yum repos with debug mode? - yum

Question

When i run puppet apply, it tries to install packages using the following command:
/usr/bin/yum -d 0 -e 0 -y install couchdb-1.2.0-7.el6
How can i configure so that it runs it as following instead:
/usr/bin/yum -y install couchdb-1.2.0-7.el6
That is, without removing the debug logs?

Answer 1

You could create a module with an exec resource in it.

> command => "/usr/bin/yum -y -d 0 install couchdb-1.2.0-7.el6",
> path => "/usr/local/bin/:/bin/",

as a test I did an update to my wget. Before running the module wget was at 1.11.4-2.el5. In my repository I had 1.11.4-3.el5_8.1.
Here are the results of my 'yum update list wget.x86_64':
Installed Packages
wget.x86_64 1.11.4-2.el5 installed
Available Packages
wget.x86_64 1.11.4-3.el5_8.1 update
this is my puppet output after applying the class (with a debug option to show you the ouput):
debug: Executing '/usr/bin/yum -y -d 0 update wget.x86_64' notice:
/Stage[main]/Yum-update-test/Exec[wget]/returns: executed successfully
And this is the output of the 'yum update list wget.x86_64' after the class/module was applied:
Installed Packages
wget.x86_64 1.11.4-3.el5_8.1 installed

While waiting for a real fix thru this ticket:
https://tickets.puppetlabs.com/browse/PUP-3453
Your only solution is to modify directly the yum package provider:
/usr/lib/ruby/site_ruby/1.8/puppet/provider/package/yum.rb
def install
wanted = #resource[:name]
# If not allowing virtual packages, do a query to ensure a real package exists
unless #resource.allow_virtual?
yum *['-d', '0', '-e', '0', '-y', install_options, :list, wanted].compact
end
Change the '-d' value to 10 and you'll be done

Answer 3

If you provide yum the -d or -e options multiple times, it will use the most recent values. So, you can also use install_options on your package resources. For example:
package { 'wget':
install_options => ['-d' , '10' , '-e' , '1' , '-v'],
}
your puppet log will then include something like:
2017-10-19 14:02:48 +0000 Puppet (debug): Executing: '/usr/bin/yum -d 0 -e 0 -y -d 10 -e 1 -v install wget'
... and all of the debug output.
