Configuring Puppet Master for PPaaS

Follow steps given below to install Puppet Master on Ubuntu:

Download the Puppet Master distribution package for the Ubuntu release.

wget https://apt.puppetlabs.com/puppetlabs-release-<CODE_NAME>.deb
 
# For example for Ubuntu 14.04 Trusty:
wget https://apt.puppetlabs.com/puppetlabs-release-trusty.deb

Install the downloaded distribution package.

sudo dpkg -i puppetlabs-release-<CODE_NAME>.deb

Install Puppet Master.

sudo apt-get update
sudo apt-get install puppetmaster

Install Passenger with Apache.

For more information, see Install Apache and Passenger.
Change the Ubuntu hostname. Please follow the steps given below to change the Ubuntu hostname:
1. Update the /etc/hosts file.
```
sudo echo "127.0.0.1 puppet.test.org" >> /etc/hosts
```
2. Change the value of the hostname.
```
sudo hostname puppet.test.org
```
Add the following entry to the /etc/puppet/autosign.conf file:
```
*.test.org
```

Add the server=puppet.test.org line to the puppet.conf file, which is in the /etc/puppet directory.

[main]
server=puppet.test.org
logdir=/var/log/puppet
vardir=/var/lib/puppet
ssldir=/var/lib/puppet/ssl
rundir=/var/run/puppet
factpath=$vardir/lib/facter
templatedir=$confdir/templates
dns_alt_names=puppet

[master]
# These are needed when the puppetmaster is run by passenger
# and can safely be removed if webrick is used.
ssl_client_header = SSL_CLIENT_S_DN
ssl_client_verify_header = SSL_CLIENT_VERIFY

Restart the Puppet Master.
```
/etc/init.d/puppetmaster restart
```
Download the VM Tools by navigating to the following path via the PPaaS product page.
Cartridges > common > wso2ppaas-vm-tools-4.1.1
Copy and replace the content in the Puppet Master's /etc/puppet folder with the content in the <VM_TOOLS>/Puppet directory.
Configure the mandatory modules.

Mandatory modules

It is mandatory to configure the following modules when configuring Puppet Master for PPaaS:

Python Cartridge Agent Module

Download the Cartridge Agent via the PPaaS product page.
Copy the downloaded apache-stratos-python-cartridge-agent-4.1.4.zip to the /etc/puppet/modules/python_agent/files directory.
Change the file permission value, of the apache-stratos-python-cartridge-agent-4.1.4.zip file, to 0755.
```
chmod 755 apache-stratos-python-cartridge-agent-4.1.4.zip
```

Update the base.pp file in the /etc/puppet/manifests/nodes directory, with the following Python agent variables.

  $pca_name             = 'apache-stratos-python-cartridge-agent'
  $pca_version          = '4.1.4'
  $mb_ip                = 'MB-IP'
  $mb_port              = 'MB-PORT'
  $mb_type              = 'activemq' #in wso2mb case, value should be 'wso2mb'
  $cep_ip               = "CEP-IP"
  $cep_port             = "7711"
  $cep_username         = "admin"
  $cep_password         = "admin"
  $bam_ip               = '192.168.30.96'
  $bam_port             = '7611'
  $bam_secure_port      = '7711'
  $bam_username         = 'admin'
  $bam_password         = 'admin'
  $metadata_service_url = 'METADATA-SERVICE-URL'
  $agent_log_level      = 'INFO'
  $enable_log_publisher = 'false'

Optionally you can configure the MB_IP, MB_PORT, PUPPET_IP and the PUPPET_HOSTNAME in the network partition as shown below.

It must be noted that the values defined in the network partition receives higher priority over the values declared in the base.pp file ( i.e., The values declared in the base.pp file are overwritten by the values declared in the network partition.).

{
    "id": "network-partition-openstack",
    "provider": "openstack",
    "partitions": [
        {
            "id": "partition-1",
            "property": [
                {
                    "name": "region",
                    "value": "<REGION>"
                }
            ]
        },
        {
            "id": "partition-2",
            "property": [
                {
                    "name": "region",
                    "value": "<REGION>"
                }
            ]
        }
    ],
    "properties": [
        {
            "name": "payload_parameter.PUPPET_IP",
            "value": "<PUPPET_MASTER_IP>"
        },
        {
            "name": "payload_parameter.MB_IP",
            "value": "<MESSAGE_BROKER_IP>"
        },
        {
            "name": "payload_parameter.MB_PORT",
            "value": "<MESSAGE_BROKER_PORT>"
        },
        {
            "name": "payload_parameter.PUPPET_HOSTNAME",
            "value": "<PUPPET_MASTER_HOSTNAME>"
        }
    ]
}

Java Module

Copy the downloaded jdk-7u72-linux-x64.tar.gz file to the files folder, which is in the /etc/puppet/modules/java directory.

Change file permission value, of the jdk-7u72-linux-x64.tar.gz file, to 0755.
```
chmod 755 jdk-7u72-linux-x64.tar.gz
```
Update the base.pp file, which is in the /etc/puppet/manifests/nodes directory, with the following Java variables.
```
$java_distribution = 'jdk-7u72-linux-x64.tar.gz' 
$java_folder = 'jdk1.7.0_72' 
```

Configurator Module

Download the Configurator by navigating to the following path via the PPaaS product page.
Cartridges > common > wso2ppaas-configurator-4.1.1
