My use case is slightly different from yours, but what I do is use
virtual resources to get around duplicate definition errors. One of
my defines looks like this. In the class resin::files and
sites::files, I have hardcoded every possible site and environment
that could be passed in (you'll know you forgot this part if on a
puppet run you get "Failed to realize virtual resource blah"). This
is far from ideal, and I'm open to ways to do this that wouldn't
require me to do that :).
The actual use case is that for each site (which is a distinct
website), there are multiple JVM's that make various components of
that site (env_alias, which is really misnamed), We can also
vertically scale JVM's on the same machine, in different runtime
directories (the instance variable). For example, we can have
/apps/runtime/site_A/main/resin/host1_main_1,
/apps/runtime/site_A/main/resin/host1_main_2, and
/apps/runtime/site_A/jive/resin/host1_jive_1 all on the same host.
These are completely unrelated (to puppet) other than the fact that
they're all resin instances running on the same box.
So for each one, I need to make sure that /apps/runtime/site_A,
/apps/runtime/site_A/[main, jive], and /apps/runtime/site_A/[main,
jive]/resin all exist (/apps and /apps/runtime are taken care of in
resin::base. which as you see is included). All of that is handled via
virtual resources, defined in sites::files and resin::files like so:
class resin::files {
@file { "/apps/runtime/gq/main/resin":
owner => cnp,
group => cnp-admin,
mode => 0755,
require => File["/apps/runtime/gq/main"],
ensure => directory;
<much snipped.....>
And here's the complete define resin::instance.
define resin::instance(
$site_alias,
$env_alias,
$instance ="1",
$host_alias,
$resin_ver,
$java_ver,
$watchdog_port = "6700"
) {
include resin::base
include resin::files
include "resin::${resin_ver}"
include sites::files
include "java::${java_ver}"
$instance_name="${host_alias}_${env_alias}_${instance}"
$runtime_dir =
"/apps/runtime/$site_alias/$env_alias/resin/${host_alias}_${env_alias}_${instance}"
file {
"/apps/runtime/$site_alias/$env_alias/resin/${host_alias}_${env_alias}_${instance}":
owner => cnp,
group => cnp-admin,
#mode => 0755,
require => File["/apps/runtime/$site_alias/$env_alias"],
source => "/media/CNT/common/puppet/resin3-runtime",
recurse => true,
ignore => ".svn",
replace => no;
"/apps/runtime/$site_alias/$env_alias/resin/${host_alias}_${env_alias}_${instance}/conf":
owner => cnp,
group => cnp-admin,
require =>
File["/apps/runtime/$site_alias/$env_alias/resin/${host_alias}_${env_alias}_${instance}"],
ensure => "/media/CNT/$site_alias/apps/$site_alias/$env_alias/resin/conf";
}
# no class names are allowed with dots, so do a lame workaround
case $resin_ver {
"resin318": { $real_resin_ver = "resin-pro-3.1.8" }
"resin316": { $real_resin_ver = "resin-pro-3.1.6" }
}
case $java_ver {
"java1607": { $real_java_ver = "jdk1.6.0_07" }
}
file {
"/apps/runtime/$site_alias/$env_alias/resin/${host_alias}_${env_alias}_${instance}/bin/setenv.sh":
owner => cnp,
group => cnp-admin,
require =>
File["/apps/runtime/$site_alias/$env_alias/resin/${host_alias}_${env_alias}_${instance}"],
mode => 0755,
content => template("resin/setenv.sh.erb");
}
# these two are defined in sites::files
realize File["/apps/runtime/$site_alias"]
realize File["/apps/runtime/$site_alias/$env_alias"]
# this is defined in resin::files above
realize File["/apps/runtime/$site_alias/$env_alias/resin"]
}
