I've been at this for less than a week and primarily concentrating on ubuntu,
not RHEL/CentOS so take this with a grain of salt
You have to be careful when installing packages from another repo but
generally, you just keep the EPEL repo disabled and instead of using the
built-in package command, you would want to 'exec' something like...
exec('/usr/bin/yum --enablerepo=epel install -y ganglia-gmond') and I would
also note that you have to ensure that the rpm-gpg key is installed for the
epel repo BEFORE that command is executed - I believe you already provided the
gpg-key URL to us.
something like this should work (adapt for rpm/yum and note that rpm stores
keys in /etc/pki/rpm-gpg)...
class apt {
package { "apt":
ensure => installed,
}
file{"/etc/apt/sources.list":
ensure => present,
owner => root,
group => root,
mode => 0444,
content => template("apt/sources.list.erb"),
require => Package["apt"],
}
exec{"/usr/bin/apt-get update":
refreshonly => true,
subscribe => File["/etc/apt/sources.list"],
require => File["/etc/apt/sources.list"],
}
# MongoDB Key
apt::key { "7F0CEB10":
keyid => "7F0CEB10",
ensure => present,
}
}
define apt::key($keyid, $ensure, $keyserver = "keyserver.ubuntu.com") {
case $ensure {
present: {
exec { "Import $keyid to apt keystore":
path => "/bin:/usr/bin",
environment => "HOME=/root",
command => "gpg --keyserver $keyserver --recv-keys $keyid && gpg
--export --armor $keyid | apt-key add -",
user => "root",
group => "root",
unless => "apt-key list | grep $keyid",
logoutput => on_failure,
}
}
absent: {
exec { "Remove $keyid from apt keystore":
path => "/bin:/usr/bin",
environment => "HOME=/root",
command => "apt-key del $keyid",
user => "root",
group => "root",
onlyif => "apt-key list | grep $keyid",
}
}
default: {
fail "Invalid 'ensure' value '$ensure' for apt::key"
}
}
}
