$ info cobbler

Cobbler is a Linux installation server that

allows for rapid setup of network installation

environments. It glues together and automates

many associated Linux tasks so you do not have to

hop between lots of various commands and

applications when rolling out new systems, and,

in some cases, changing existing ones.

$


Command line access is simple: Setup:

$ cobbler import --name=RHEL5 --mirror=/mnt/dvd

$ cobbler import --name=Centos5 --path=rsync://foo

Create and edit distros:

$ cobbler distro edit --name=RHEL5-i386 --kopts="noapic x=y z=4"

Define some roles for your systems to fill:

$ cobbler profile edit --name=RHEL5-i386 --

kickstart=/path/to/template.ks --ksmeta="somevar=1 othervar=2"

$ cobbler profile copy --name=RHEL5-i386 --newname=webservers

Also help manage updates as they relate to installation and post-

installation:

$ cobbler repo add --name=f10-updates --mirror=http://foo

$ cobbler reposync

$ cobbler profile edit --name=desktops --repos="f10-updates"

Puppet

Puppet


$ info puppet

Puppet is a tool designed to manage the

configuration of Unix-like and Microsoft Windows

systems declaratively. In the Puppet manifests,

the user describes system resource and resource

state either in Puppet or Ruby DSL (domain-

specific language).

$

Puppet


class ssh{

package { "openssh-server":

ensure => latest,

}

file { "/etc/ssh/sshd_config":

owner => root,

group => root,

mode => 644,

source => "puppet:///ssh/sshd_config",

}

service { ssh:

ensure => running,

hasrestart => true,

subscribe => File["/etc/ssh/sshd_config"],

}

Marionette Collective


$ info mcollective

MCollective is a framework to build server

orchestration or parallel job execution systems.

It enables real-time discovery of network

resources and can select which resources to

affect based on configuration data from leading

systems management platforms, including Puppet.).

$ info redmine

Redmine is a free and open source, web-based

project management and bug-tracking tool. It

includes calendar and Gantt charts to aid visual

representation of projects and their deadlines.

It supports multiple projects. Redmine provides

integrated project management features, issue

tracking, and support for multiple version

control options.

$

$ info jenkins

Jenkins provides continuous integration services

for software development, primarily in the Java

programming language. It supports SCM tools

including CVS, Subversion, Git and Clearcase and

can execute Apache Ant and Apache Maven based

projects, as well as arbitrary shell scripts and

Windows batch commands.

$

$ info cucumber

Cucumber lets software development teams describe

how software should behave in plain text. The

text is written in a business-readable domain-

specific language and serves as documentation,

automated tests and development-aid - all rolled

into one format.

$

Red Hat Package Manager


$ info rpm

RPM Package Manager (RPM) is a package management

system. The name RPM variously refers to the .rpm

file format, files in this format, software

packaged in such files, and the package manager

itself. RPM was intended primarily for GNU/Linux

distributions; the file format is the baseline

package format of the Linux Standard Base.

Vagrant

$ info vagrant

Vagrant is a tool for building and

distributing virtualized development

environments.

By providing automated creation and

provisioning of virtual machines using

Oracle’s VirtualBox, Vagrant provides

the tools to create and configure

lightweight, reproducible, and portable

virtual environments that can be run on

development workstations and laptops.

$

$ info katello

Katello helps you take control of your software and

your systems in an easy-to-use and scalable manner.

Katello can pull in content from remote repositories,

local directories and ISOs. You can then organize that

content into repositories that are easily searchable,

filtered, manipulated and controlled in a locked-down

container called an Environment.

Katello integrates the open-source projects Pulp,

Candlepin, and Foreman with a modern Rails front end

and a Python CLI to make it easier than ever to manage

your systems and content the way you do business.

$ info katello

Liquibase is a database-independent library for tracking,

managing and applying database changes. It is built on a

readable yet trackable form and checked into source control.

Liquibase Supports:

• Extensibility

• Merging changes from multiple developers

• Code branches

• Multiple Databases

• Managing production data as well as various test datasets

• Cluster-safe database upgrades

• Automated updates or generation of SQL scripts that can be

approved and applied by a DBA

• Update rollbacks

• Database ”diff“s

• Generating starting change logs from existing databases

• Generating database change documentation
