VMware vFabric Application Director™ Puppet Service

Puppet Labs Logo

Overview

Puppet Labs provides an integration solution for VMware® vFabric™ Application Director™. The Puppet service enables Application Director customers to deploy applications via Puppet manifests or deploy vFabric Application Director blueprints using existing Puppet modules available on the Puppet Forge. The solution leverages the vFabric Application Director management console to configure Puppet classes and utilize Puppet Forge modules to deploy services and create vFabric Application Director blueprints.

Puppet Modules as vFabric Application Director Blueprints

Deploying Puppet modules as blueprints in vFabric Application Director environments consists of the following steps:

  • Install and setup Puppet service.
  • Download and translate Puppet module.
  • Install and setup application service.
  • Configure and deploy application blueprint.

Module Installation

The (github repo)[https://github.com/puppetlabs/puppetlabs-appdirector.git] needs to be installed on the client accessing the vFabric Application Director management console. The repo provides example scripts, as well as a translation utility to map Puppet modules to vFabric Application Director compatible service scripts.

Requirements:

  • Puppet Enterprise 2.5.0+
  • or Ruby 1.8.7 and Puppet open source 2.7.14+.

Installation:

Puppet Service

Users have a choice of installing Puppet Enterprise or Puppet as a service in the vFabric Application Director environment. Both installation scripts only deploy puppet agent.

Puppet Enterprise

  1. Create new service in the catalog.
  2. Use the following values:
    • Name: Puppet Enterprise
    • Version: 2.5.3
    • Tags: "Other"
    • Supported OSes: (Click here to see the full list.)[http://puppetlabs.com/puppet/requirements/]
    • Supported Components: script.
  3. Add scripts/puppet_enterprise.sh to the service install lifecycle.
  4. Add global_conf properties with the value: https://${darwin.server.ip}:8443/darwin/conf/darwin_global.conf (see global_conf.png)
  5. Add installer_payload properties with the approriate package for the operating system: https://pm.puppetlabs.com/puppet-enterprise/2.5.3/
  6. Add puppet_server properties with the approriate puppet master name, otherwise defaults to 'puppet'.
  7. Add agent_cert properties with the systems certificate name, otherwise defaults to the hostname.

Puppet

  1. Create new service in the catalog.
  2. Use the following values:
    • Name: Puppet
    • Version: 2.7
    • Tags: "Other"
    • Supported OSes: Any Operating System in RHEL and Debian OS family.
    • Supported Components: script.
  3. Add scripts/puppet_community.sh to service install lifecycle.
  4. Add the global_conf properties with the value: https://${darwin.server.ip}:8443/darwin/conf/darwin_global.conf (see global_conf.png)

Puppet Modules

There are more than 400 modules in the Puppet Forge, and they can be used to deploy a wide variety of popular applications. The example below describes the process of deploying MySql module; however, any other module can be used. For complex modules, please visit the Puppet Forge for usage examples and documentation.

  1. Search and install modules

    $ puppet module search puppetlabs
    Searching http://forge.puppetlabs.com ...
    NAME                             DESCRIPTION                                                                               AUTHOR        KEYWORDS                                    
    puppetlabs-apache                This is a generic Apache module that includes support for creating VirtualHosts.          @puppetlabs   apache web virtualhost                      
    puppetlabs-collectd              This is a module for managing the Collectd statistical collection daemon.                 @puppetlabs   collectd statistics RRD                     
    puppetlabs-vcsrepo               A module that provides the vcsrepo type and providers.                                    @puppetlabs   vcs repo svn subversion git hg bzr CVS      
    puppetlabs-gcc                   Module to manage gcc                                                                      @puppetlabs   gcc compiler                     
    ...
    $ puppet module install puppetlabs-mysql
    Preparing to install into /Users/nan/.puppet/modules ...
    Downloading from http://forge.puppetlabs.com ...
    Installing -- do not interrupt ...
    /Users/tom/.puppet/modules
    └── puppetlabs-mysql (v0.4.0)
    
  2. Create a new service in the catalog.

  3. Use the Puppet module name and version for the new service (see module documentation for OS support).

    * Name: MySQL
    * Version: 0.4.0
    ...
    
  4. List available Puppet classes:

    $ ./bin/appdirector_module.rb
    Available Puppet Classes:
    mysql
    mysql::backup
    mysql::config
    mysql::java
    mysql::params
    mysql::python
    mysql::ruby
    mysql::server
    mysql::server::account_security
    mysql::server::monitor
    mysql::server::mysqltuner
    
  5. Generate appdirector service script for MySql Puppet class:

    $ ./bin/appdirector_module mysql
    #!/bin/bash
    
    . $global_conf
    
    export PATH=$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
    
    set -u
    set -e
    
    puppet module install puppetlabs/mysql
    
    cat > /tmp/mysql.pp <<EOF
    class { 'mysql':
     package_ensure => $package_ensure,
     package_name   => $package_name,
    }
    EOF
    puppet apply --verbose /tmp/mysql.pp
    
  6. Add any Puppet class parameters as properties with the type string and default value of undef (do not quote).

    • name: package_ensure, type: string, default: undef
    • name: package_name, type: string, default: undef
  7. Add the global_conf properties with the value: https://${darwin.server.ip}:8443/darwin/conf/darwin_global.conf (see global_conf.png)

  8. Create a new blueprint for MySQL.

  9. Add Puppet service.

  10. Add MySQL service.

  11. Create dependency between MySQL and Puppet service.

  12. Deploy application.

One of the benefits of deploying Puppet in vFabric Application Director environment is Puppet's ability to manage resources. For example, once the MySql module is deployed, vFabric Application Director users can describe and deploy MySql databases using the following Puppet manifest:

mysql::db { 'mydb':
  user     => 'myuser',
  password => 'mypass',
  host     => 'localhost',
  grant    => ['all'],
}

Examples

In the sections below, we will provide step-by-step instructions for deploying Jenkins, and a custom Puppet manifest.

Deploying Jenkins

  • Install rtyler/jenkins module from forge:

      $ puppet module install rtyler/jenkins
      Preparing to install into /Users/nan/.puppet/modules ...
      Downloading from http://forge.puppetlabs.com ...
      Installing -- do not interrupt ...
      /Users/tom/.puppet/modules
      └── rtyler-jenkins (v0.2.3)
    
  • Create new service in the catalog:

      * Name: Jenkins
      * Version: 0.2.3
      ...
    
  • Generate appdirector service script for jenkins puppet class:

      $ ./bin/appdirector_module jenkins
      #!/bin/bash
      
      . $global_conf
      
      export PATH=$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
      
      set -u
      set -e
      
      puppet module install rtyler/jenkins
      
      cat > /tmp/jenkins.pp <<EOF
      class { 'jenkins':
      
      }
      EOF
      puppet apply --verbose /tmp/jenkins.pp
    
  • Add the global_conf properties with the value: https://${darwin.server.ip}:8443/darwin/conf/darwin_global.conf (see global_conf.png)

  • Create a new blueprint for Jenkins

  • Add Puppet and Jenkins service.

  • Create dependency between Jenkins and Puppet service.

  • Deploy application.

Custom Puppet Manifests

Once Puppet's service is created, vFabric Application Director can also deploy custom manifests. Use the scripts/puppet_manifests.sh as a template and add any puppet manifests in the appropriate section. The scripts/example.sh provides an example where ssh service is changed to port 80, restarts sshd as necessary, and enforces a specific root user password.
