puppet how to manually run a class

1)
how to manually run a class
------------------------------

$echo 'include rjil::system::apt' | puppet apply
$echo 'include rjil::system::apt' | puppet apply --debug
$echo 'include rjil::system::apt' | puppet apply --debug ---noop

2)
How to add entry in /etc/hosts
---------------------------------------

$echo "include rjil::jiocloud::dns" | puppet apply

notify {"ip=${ip}, cname=${cname}, name=${name}":}  === print
notify {"ip=${ip}, ip_real=${ip_real}":}

Notice: ip=false, cname=keystone.service.consul, name=identity.jiocloud.com
Notice: ip=false, ip_real=10.140.15.69

/etc/puppet/modules.overrides/rjil/manifests/jiocloud/dns/entry.pp

3)
How consul check keystone service
-------------------------------------------------------
a)
$vim puppet-rjil/manifests/keystone.pp

  rjil::jiocloud::consul::service { "keystone":
    tags          => ['real'],
    port          => 5000,
  }

b)
$vim puppet-rjil/manifests/jiocloud/consul/service.pp

  file { "/etc/consul/$name.json":
    ensure => "present",
    content => template('rjil/consul.service.erb'),
  } ~> Exec <| title == 'reload-consul' |>

c)
vim /etc/consul/keystone.json

{
  "service": {
    "name": "keystone",
    "port": 5000,
    "tags": [
      "real"
    ],
    "check": {
      "script": "/usr/lib/jiocloud/tests/service_checks/keystone.sh",
      "interval": "10s"
    }
  }
}

* Consul will read this json file and execute the script in the "check" section, then register the service if check is success.

d)
$vim /usr/lib/jiocloud/tests/service_checks/keystone.sh

#!/bin/bash
set -e
/usr/lib/nagios/plugins/check_http -S -H 10.140.15.66 -p 5000

How to test puppet code : Test Spec error and Compilation error

1)
#sudo apt-get install ruby
#sudo apt-get install ruby-dev

2)
http://bundler.io/
#sudo gem install bundler

3)
Clone puppet project from github and goto cloned folder and run.

#bundle install
OR
#bundle install --gemfile=Gemfile

* This will install all the dependencies defined in the "Gemfile"
* Use `bundle show [gemname]` to see where a bundled gem is installed.
* https://puppetlabs.com/blog/the-next-generation-of-puppet-module-testing

4)
Run spec tests in a clean fixtures directory
#rake spec
OR
#bundle exec rake spec

* Run "#rake" to get help page

5)
Check that your Puppet manifest conform to the style guide
#bundle exec rake lint
#bundle exec rake lint | grep ERROR

To check for compilation errors and view a log of events.
#puppet apply --noop --debug manifests/init.pp
