This document summarizes a presentation about FullStackAutomationwithKatelloandForeman. It introduces the presenters Justin Miller and Weston Bassler and their backgrounds. The presentation covers the Foreman project, Katello project, and how they work together. Foreman is an open source tool for provisioning, configuring, and managing servers. Katello adds content management capabilities like repositories and subscriptions. The document outlines key features of provisioning, configuration, repositories, subscriptions, and more. It includes links to demo videos showcasing functions like host discovery, bulk actions, and Docker integration.

4. TheForeman
What is the Foreman?
“Foreman is an open source project that helps system
administrators manage servers throughout their lifecycle,
from provisioning and configuration to orchestration and
monitoring. Using Puppet, Chef, Salt, and Foreman's smart
proxy architecture, you can easily automate repetitive
tasks, quickly deploy applications, and proactively manage
change, both on-premise with VMs and bare-metal or in the
cloud.”
-From theforeman.org

5. TheForeman
● Provisioning, System Configuration and Registration
○ Automated provisioning of bare metal systems from OS
to application deployment.
○ Management abstractions for targeting and
configuration via concepts such as company, location,
arbitrary host group, and arbitrary environment
definitions.
○ Deep native integration with Puppet, with parameter
configuration targeting available via traditional
Hiera concepts but also via the abstractions mentioned
above.

6. TheForeman
● Provisioning, System Configuration and Registration Cont…
○ Audited tracking of all changes in one location.
○ Transparent locality via “capsul” servers that can
serve as local puppet masters and package repositories
for each site.
○ An extremely powerful REST API and command line tool
enable automation of any task you can think of.
○ Reports and dashboard that make auditing compliance a
breeze.

7. AUTOMATIONOFALLTHINGS

8. TheForeman
● Provisioning
○ private/public cloud, bare metal and Docker!!!!!!
○ Powerful dynamic templates and logic driven scripting
can dynamically build kickstarts based on your
requirements.
○ Dynamic discovery rules via facts such as number of
drives, hardware model, location, subnet make
tailoring automated configuration and deployment by
role possible. IE: When someone in the datacenter
unboxes your server, racks it, and plugs into into
network and power; it will automatically set itself
up.

9. TheForeman
● Provisioning Cont… (Defaults)
○ AWS, Ovirt, VMware, OpenStack, Rackspace, Google
Compute and more
○ Supported Operating systems

10. TheForeman
● Types of Deployment
○ pxe via kickstart
○ images via cloudinit etc
○ Bootdisk plugin - Boot images are written as hybrid
ISO images (usable as ISOs or USB disks), and booted
either from physical media or virtual disk/CDROM
FYI - http://cloudinit.readthedocs.org/en/latest/

11. TheForeman
● Orchestration
○ Smart Proxy Technology
○ Foreman-Smart proxy - helps Foreman commission a new
host and general orchestration
○ Should be on or near The Foreman host
○ Restful API to the various subsystems
■ DHCP, DNS, Puppet, Puppet CA, Realm & TFTP

12. TheForeman
● System Configuration Management
○ Built in Puppet
○ Classes, parameters and auto signing by default
○ Other SCM available (later)
● Grouping of Hosts
○ Host Groups for assigned attributes and functions
■ Puppet Configs, OS, Activation Keys, etc…
■ Much Key to Automation

13. TheForeman
● Inventory Management and Monitoring
○ Trends and Charts
○ Reports from Puppet
● User Management
○ LDAP Auth
○ Users and User Groups
○ Roles

16. Katello
What is Katello?
“Katello brings the full power of content management
alongside the provisioning and configuration capabilities of
Foreman.”
-From katello.org

17. Katello
● What Does Katello Provide?
○ Subscription Content Management
○ Auditing of deployed packages, errata, targeting of
non compliant nodes.
○ Environment update via defined flows. IE: Dev -> Test
-> Production

18. Katello
● Repository/Content Management
○ RPM, Docker, Puppet Content, Red Hat Subcriptions
■ Docker - sync from a registry or upload your own
images
■ Puppet - import puppet modules from git/Puppet
Forge
○ Products - A group of content that you register to
each host.
○ Schedule sync/upload of your repos

19. Katello
● Host Collections - allow for you to group hosts together
● Bulk actions - run install/upgrade/remove against a host
collection or a selected set of hosts
● Demo to come

20. Katello
● Bulk Actions
https://www.youtube.com/watch?
v=5ja1xCL7QPY

21. TheForeman&Katello
● Register Your Products to Host Groups during provisioning
● Create Activation Keys for Subscription
○ Activation Keys provide a mechanism to define
properties that may be applied to Content Hosts during
registration like Products, Repos, etc…
CONGRATS!!! INFRASTRUCTURE = PWNED

24. TheForeman&Katello
● Other Awesomeness
○ Plugins: Docker, Chef, Salt, MCollective
○ Plugins URL - Plugins for things such as bootdisk,
chef, docker, etc
■ http://projects.theforeman.
org/projects/foreman/wiki/List_of_Plugins
○ Rest API
○ CLI -> HAMMER CLI
○ Reporting Plugins -> ABRT (bug), OpenScap (security)
○ Now Ansible Integration

25. DockerDemo
