This document provides instructions for installing various development tools on Mac OSX, including Xcode, command line tools, Homebrew, Ruby, Python, VirtualBox, Vagrant, Chef, and Ansible. It describes downloading and installing each tool, and in some cases providing additional configuration steps or notes on cleaning up existing installations. The overall purpose is to set up a standard development environment with common utilities.
The document discusses using Docker containers and Puppet to compartmentalize services running on a personal server. Previously, many services like Postfix, Dovecot, DNS, etc. were running on the server with no isolation. The approach taken was to define Puppet profiles for each service, build Docker containers from those profiles, and run the containers independently with their own isolated environments. This improves security, ease of development and deployment, and allows immutable infrastructure by replacing containers instead of changing server configurations. Challenges discussed include Docker bugs, inconsistent Debian packages, and future plans to add HAProxy and a container registry.

This document discusses Docker and Puppet and how they can be used together. It suggests using Puppet to install and configure Docker on the host system, and then using Dockerfiles to build container images in a deterministic way. While Puppet could theoretically be used to build containers, the document argues it is better to use Dockerfiles for image builds and to separate operational concerns like logging and monitoring into separate containers for better portability and flexibility.
#OktoCampus - Workshop : An introduction to AnsibleCédric Delgehier
- A playbook is defined to check if a pattern is present in the content of a web page retrieved from localhost. The playbook registers the content and fails if the defined pattern is not found.
- The playbook is modified to define different patterns for different host groups - the groups "prod" and "recette" would each have their own unique pattern to check for.
- The playbook uses Ansible modules like uri to retrieve a web page, register to store the content, and fail if a registered pattern is not found in the content. Variables and conditionals allow defining patterns dynamically based on host groups.
Puppet is an open source tool used to automate server configuration management. It ensures servers are configured and packages installed as defined. Puppet manages configuration through resources like packages, files, users and more. It can install packages, configure files and folders, manage services, create users/groups, and run commands. Puppet applies configurations idempotently so they can be run multiple times without changing the server unless the configuration changes.
This document provides an overview of Puppet configuration management software. It discusses the need for configuration management and introduces Puppet. It covers Puppet basics like the Puppet master, agents, catalogs, resources and attributes. It also discusses Puppet concepts like idempotence, declarations, drift, tags and classes. The document demonstrates how to set up a Puppet master and agent and provides examples of Puppet manifests using resources like packages, files, services and more. It also discusses Puppet modules, the fileserver and provides exercises for using Puppet.
A book for learning puppet by real example and by building code. Chapter 1 gives you basic introduction and sets you up with a server-agent using Vagrant so that you can do hands-on.
Puppet is a configuration management tool that allows systems to be provisioned in a consistent, automated way. It uses manifests and resources to describe a system's configuration. Resources include packages, services, files and users. Modules contain reusable sets of resources. Templates allow variables to be used when generating configuration files. Puppet can be used with Vagrant for development and provisioning, and in production via a Puppet master to distribute configuration to clients.
Kris Buytaert discusses how they used Vagrant, Puppet, and other tools to improve their Puppet development and testing workflow. Some key points:
- Vagrant allows creating reproducible development environments for Puppet code.
- Puppet style guides help write more readable manifests. Tools like Puppet Lint can validate style.
- Testing Puppet code with rspec-puppet, cucumber-puppet, and other tools helps prevent errors.
- Using Git, GitHub, and Git flow practices helps manage Puppet modules in version control.
- Jenkins can automate building, testing, and deploying Puppet code and modules.
- Demonstr
Puppet is automation software that helps system administrators manage infrastructure by automating provisioning, configuration, and other repetitive tasks. It ensures consistency and stability. Puppet consists of a Puppet Master and Puppet Agents. Vagrant provides a way to easily create and configure virtual development environments using configuration files and automation (e.g. Puppet). It uses Oracle VirtualBox and allows specifying and provisioning resources. Benefits include consistent environments for development, testing, and teams.

The DevOps movement aims to improve communication between developers and operations teams to solve critical issues such as fear of change and risky deployments. But the same way that Agile development would likely fail without continuous integration tools, the DevOps principles need tools to make them real, and provide the automation required to actually be implemented. Most of the so called DevOps tools focus on the operations side, and there should be more than that, the automation must cover the full process, Dev to QA to Ops and be as automated and agile as possible. Tools in each part of the workflow have evolved in their own silos, and with the support of their own target teams. But a true DevOps mentality requires a seamless process from the start of development to the end in production deployments and maintenance, and for a process to be successful there must be tools that take the burden out of humans.
Apache Maven has arguably been the most successful tool for development, project standardization and automation introduced in the last years. On the operations side we have open source tools like Puppet or Chef that are becoming increasingly popular to automate infrastructure maintenance and server provisioning.
In this presentation we will introduce an end-to-end development-to-production process that will take advantage of Maven and Puppet, each of them at their strong points, and open source tools to automate the handover between them, automating continuous build and deployment, continuous delivery, from source code to any number of application servers managed with Puppet, running either in physical hardware or the cloud, handling new continuous integration builds and releases automatically through several stages and environments such as development, QA, and production.
This document discusses using Puppet to program IT infrastructures. It introduces Puppet as a tool for automating infrastructure management and provisioning. Puppet uses a declarative language and allows infrastructure to be coded and version controlled. The document provides an overview of Puppet architecture with Master and Agent nodes and explains how nodes are defined and organized using classes and modules. It also shows examples of Puppet code for configuring common services and managing files and templates.
The document discusses how immutable infrastructure can be achieved through Puppet by treating systems configuration as code. Puppet allows defining systems in code and enforcing that state through automatic idempotent runs, compensating for inherent system mutability. This brings predictability to infrastructure and allows higher level operations by establishing a foundation of reliable, known states.
This document provides instructions for setting up Dexterity in Plone in 15 minutes or less. It outlines downloading required resources, Dexterity's philosophy of reuse over reinvention and Zope concepts, and provides step-by-step instructions for installing Dexterity via buildout, creating a simple content type through the web interface, and adding a custom Dexterity content type through the filesystem.
This document discusses how Vagrant and Puppet can help solve common development environment issues by providing easy and repeatable deployment. Vagrant allows developers to quickly set up and provision virtual development environments that match production. Using Puppet for configuration management further ensures consistency between environments. The document outlines how Vagrant reduces setup time, ensures parity between environments, and isolates dependencies and versions, improving the development workflow.
1. The document discusses moving from a Dev to DevOps model by addressing issues like siloization between development and operations teams and embracing concepts like infrastructure as code.
2. It recommends several DevOps tools for infrastructure automation including Puppet, Vagrant, and VeeWee which allow developers to define infrastructure in code and provision environments.
3. The Puppet Domain Specific Language (DSL) is demonstrated for declaring resources like users, files, packages, and services with attributes and relationships between them in a declarative way.
This document discusses using Fabric and Puppet together to streamline system administration tasks. Fabric can be used to execute tasks across multiple servers using Python, while Puppet defines infrastructure using code and templates. The document suggests using Fabric to set up environments and trigger Puppet deployments, while defining nodes and classes in Puppet. This allows taking advantage of Fabric's host management capabilities and Puppet's declarative approach. Initial Fabric functions would prepare environments, while global functions handle setup/teardown. Puppet would define the desired configuration to deploy using its domain-specific language.

2. What Vagrant is and what it isn’t
● Vagrant is a wrapper for Virtual Machine providers (VirtualBox, VMWare,
etc) .
● Vagrant can use provisioners, including shell scripts, puppet, chef and
others.
● Puppet (which we’ll cover here) is but one option of provisioners supported by
Vagrant; there are others like Chef, Ansible, Salt, etc.
● Vagrant is no configuration management tool.
3. What is Puppet and where does it fit in?
● Puppet can be seen series of system-level asserts. Puppet resources are
meant to be idempotent, i.e. stateless (just like HTTP).
● Puppet is a declarative language. In other words, it does not specify steps,
but states your system must be in.
● Couldn’t I just do everything Puppet does using shell provisioners?
○ Well, yeah but: You would have to write distribution-specific code for each
box (think apt-get vs yum, deb vs rpm, etc).
○ Things will quickly get messy if you need complex provisioning steps that
depend on each other, files to include, third-party modules, etc.
○ Your code would be order-dependent (stateful).
4. Manifest files - I
● These are the config files for Puppet: This is where you define resources
for your system.
● The main manifest file (entry script) must be pointed to in your
Vagrantfile
● Puppet is a Ruby-inspired DSL.
● Resources are not necessarily applied to the target system in the order
they are written in the manifests. If a resource must be applied before or
after some other resource, you must explicitly say so.
5. Manifest files - II
Example manifest file - Clone project rails/rails from github:
Exec {
path => [ "/bin/", "/sbin/" , "/usr/bin/", "/usr/sbin/","/usr/local/bin" ]
}
exec { 'sys_update':
command => 'apt-get update --fix-missing',
}
package { 'git-core':
require => Exec['sys_update'],
ensure => 'installed',
}
exec{ 'clone rails project':
command => 'git clone https://github.com/rails/rails.git',
cwd => '/home/foo/',
require => Package['git-core'],
}
define a command
install a package but only after system
update (this is the command you’ve
define above)
set defaults for a
resource (in this case,
default path for Execs)
clone a project using git
but first make sure the
git package is installed
6. Resources
● Resources are the basic building blocks in Puppet.
● Resources are state definitions. They are not commands that get run, but
assertions that get verified. They should not have side-effects.
● A resource looks like this:
type {'title':
attribute => 'value',
}
● Common resource types are Exec, Package, File and Service.
● Official docs entry for resources.
7. Resource types: Package I
● This resource type is used to assert that a package is in a given state.
● Attribute provider is used to define what kind of package will be used (it
defaults to your system’s default package manager but others can be
used, including things like pip, gem and npm.
● install a package using default provider (depending on your OS):
package {'apache2':
ensure => 'installed',
}
8. Resource types: Package II
● Making sure a pip package is updated:
package {'Django':
ensure => 'latest',
provider => 'pip',
}
More info: Puppet Docs for Package Resource
9. Resource types: Exec
● This resource type defines a shell command to be run in your virtual machine.
● The command must be idempotent or stateless: it should be able to run
multiple times with no errors. Use attributes like onlyif, unless and
creates to control when they run.
● example:
exec {'install chrome browser':
command => 'dpkg -i google-chrome-stable_current_i386.deb',
cwd => "/home/username/Downloads",
creates => "/usr/bin/google-chrome",
}
this command creates a
file, so Puppet knows it
shouldn’t be run if the
file already exists
10. Resource types: File
● It merely asserts that a file exists. So if it doesn’t exist, it is created; if it already
exists, nothing is done.
● Assert that a file exists and is owned by a given user:
file {'make sure my-file exists':
path => '/path/to/my-file',
ensure => 'present',
owner => 'johndoe',
}
11. Resource types: File II
● Make sure a directory exists and has given mode
file {'settings-directory',
ensure => 'directory',
path => '/path/to/settings-directory',
mode => 755,
recurse => true,
}
all child files will
have given
mode as well
12. Classes
● Just a simple way to group resources together, introducing modularization
and reuse:
class python {
package{'python-dev':
ensure => 'installed',
}
package{'python-pip':
ensure =>'installed',
require => Package['python-dev'],
}
}
include python
enforce ordering
between resources
don’t forget to
include what you
have defined
13. Heads-up
● In order to be able to launch 64-bit boxes, make sure you have
‘Virtualization Support’ enabled in your computer BIOS.
● You need to include all classes you want to be able to use, even though
they are not your ‘entry point’.
