Scripts and Puppet manifests to easily install Maestro and related services (jenkins, archiva,...) from scratch

Nodes defined

There are a few useful nodes defined for a Maestro master server, agent node and maestro master+agent node. See the manifests/nodes/default files for details. Includes classes defined in Maestro-Nodes for reusability.

Installing in a fresh machine

The script can install a Puppet master with all the required Maestro Puppet configuration and trigger a Puppet update to install Maestro and a Maestro agent from a minimal CentOS 6.3 server.

From a minimal CentOS 6.3 server you can run the script to automatically install everything, passing your MaestroDev provided username and password.

curl -L | bash -s USERNAME PASSWORD

The puppet process can also be run in the background by setting the environment variable DAEMON to true.

curl -L | DAEMON=true bash -s USERNAME PASSWORD

Other parameters

The script accepts the following parameters in order

  • username
  • password
  • node type [master, master_with_agent, or any of the other puppet nodes defined under manifests/nodes/default]
  • environment [development] If set to development the rpm won't be installed, useful for Vagrant environments

Setting up a Maestro server without any of the other servers (Maestro Agent, Jenkins, Archiva, etc)

You can install the Maestro server without any of the servers needed by the default examples. To do this, simply specify the master_base node type when invoking the script. Like so:

curl -L | bash -s USERNAME PASSWORD master_base

Setting up a Puppet Master only

You can ask the to skip the Puppet step at the end. This will set up a Puppet master on the machine, which can then be customised and used for setting up other machines.

curl -L | sudo NO_PROVISION=true bash -s USERNAME PASSWORD

Creating an Image

To create an image of the Maestro master, it is best not to start the Maestro software as it will configure itself for the current host. In this case, set MAESTRO_ENABLED to false.


To later re-enable Maestro, edit the value in Hiera (see Customizing below).

Installing agents on CentOS with Puppet

The script can install a Puppet agent and trigger a Puppet update to install a Maestro agent from a minimal CentOS 6.3 server, installing typical tools like git, subversion, ruby, java,...

From a minimal CentOS 6.3 server you can automatically install the Maestro Agent, passing the hostname of the Maestro master server. Optionally you can pass the ip of the master server too if there is no dns entry for the master hostname and it will create an entry in the agent /etc/hosts file to properly resolve the name to that ip.


Installing the agents on a machine with non-standard hostname.

By default, agent hosts must have the word agent in their name. If you want to install the agent on a machine that doesn't have a host name that has the word agent in it, you must first add a node definition on the puppet master for this new machine. From the puppet master do the following:

cd /etc/puppet


Where AGENTHOSTNAME is the name of the host where you wish to install the agent.

Then, simply follow standard agent installation instructions on the agent host.


Maestro Master

You can run the to install all prerequisites (ie. Puppet and modules upgrades) in the master, but skipping the Puppet step at the end

curl -L | sudo NO_PROVISION=true bash -s USERNAME PASSWORD

Then puppet can be run as usual with the --noop flag to check that all changes look correct before applying them. Note that some steps are expected to fail as they depend on file downloads that don't actually happen in noop mode. In case of doubts please use your Maestro support account to contact us.

puppet agent --test --noop

If all looks correct Puppet can be run again to aply the changes

puppet agent --test

Maestro Agents

Agents can be updated the same way. First with NO_PROVISION to update the prerequisites if necessary, then running Puppet. We recommend updating one agent and check that it shows up in the Infrastructure tab in the Maestro Web UI before upgrading the rest of the agents.

curl -L | sudo NO_PROVISION=true bash -s MASTER_HOSTNAME [MASTER_IP]
sudo puppet agent --test --noop

If all looks good

sudo puppet agent --test


Issues with hostnames

You might receive the following error:

Unable to find fact 'fqdn', please check your networking configuration

This should be corrected by ensuring that hostname and hostname -d have the expected values. This will usually involve adjusting /etc/sysconfig/network on CentOS (and either rebooting or changing temporarily with hostname as well). You may also need to change /etc/resolv.conf and/or /etc/hosts.

Problems can also be encountered if the hostname or domain name includes uppercase characters. Use lowercase for more predictable results.


You can customize the installation using Puppet 3 Hiera's capabilities. The default configuration variables are in /etc/puppet/hieradata/default.yaml, and can be customized in /etc/puppet/hieradata/common.yaml for all nodes or /etc/puppet/hieradata/$clientcert.yaml for node specific configuration as defined in hiera.yaml.

You can add your own Puppet nodes to /etc/puppet/manifests/nodes and they will take precedence over those defined in /etc/puppet/manifests/nodes/default and will not be overwritten on upgrades.


This project uses librarian-puppet to fetch all the required puppet modules as defined in Puppetfile, bundler for the gem dependencies defined in Gemfile, and rspec-puppet for unit tests.

To build everything and run the specs

bundle install
bundle exec rake

To just fetch the required puppet modules

bundle exec librarian-puppet install


There are several Vagrant boxes defined:

  • default: provisions using the modules checkout out in the local repo
  • maestro: provisions using the script and modules from rpm as it would do in a real server
  • agent: provisions an agent from another Puppet server, configured by default to
You can’t perform that action at this time.
