hi list,
first of all, i'm new to puppet, and i'm evaluating it right now since
a few days in my company ( internet, books, etc as sources ).
i've been using cfengine for a few years now, and trying to get into
puppet.
i'd install puppet 0.25, because i feel a need to use regular
expressions to identify nodes
scenario:
lets say we do have a few servers to get puppetized ;) at different
sites
lets call those sites: office, cloud and datacenter
we now do have 10 webserver on each location,
forming 2 clusters
this would lead to following dns names:
web[01-05].clusterA.cloud.mydomain.com
web[01-05].clusterB.cloud.mydomain.com
web[01-05].clusterA.office.mydomain.com
web[01-05].clusterB.office.mydomain.com
web[01-05].clusterA.datacenter.mydomain.com
web[01-05].clusterB.datacenter.mydomain.com
1. let's say i want to apply a certain config just to clusterB at all
sites (like munin plugins)
i'd guess i would take node definitions for that, loading those
classes like this one
node /^web(.*)\\.clusterB\\.(cloud|office|datacenter)\\.mydomain\\.com
$/ {
include "site::clusterB::web-nodes"
}
2. now lets say, i also want all servers to have a base set of munin
plugins no matter where they are located, using the next node
definition
node /^web(.*)\\.cluster(A|B)\\.(cloud|office|datacenter)\\.mydomain\
\.com$/ {
inclde "site::web-nodes"
}
3. i want just one server to have a config afterwards
node "web01.clusterA.cloud.mydomain.com" {
include "site::cloud::clusterA::web01.clusterA.cloud.mydomain.com"
}
thought that my syntax could be wrong but i hope i got the point.
i did not try that out yet thought but would like to hear your
opinions,
if this is the preffered way to solve my "problem"?????
i thought since there are no much chances besides $hostname and $fqdn
to identify or even classify certain nodes, to apply configs to, thats
the only way
greetings
