Auto infra with_foreman_katello
This document discusses automating infrastructure with Foreman and Katello. Foreman is a tool for provisioning and managing systems through their lifecycle, including provisioning, configuration, and monitoring. Katello integrates with Foreman to add content management capabilities. It allows syncing content from various sources, organizing it with content views and libraries, and promoting it through environments. The document outlines key Foreman and Katello features like smart proxies, discovery, host groups, APIs, plugins, repositories, content views, lifecycle environments and more.

- 1. Automating Infrastructure with Foremanand Katello Sachin Ghai @sghai
- 2. Agenda ➢ Introduction ➢ Provisioning ➢Smart-proxy ➢ Plugin – Discovery ➢ Katello ➢ Content Management ➢ Demo
- 3. Foreman ➢ Provisioning andinfrastructure Management project ➢ Performs unattended systems installation of Bare Metal, Private and public clouds ➢ Supports various operating systems ➢ Extendible with various plugins ➢ DNS, DHCP and TFTP management via smart-proxy ➢ Discovers unknown hosts/systems via PXE
- 4. Foreman ➢ Manages theLife-cycle of systems by: ➢ Provisioning ➢ Configuration ➢ Integrated Configuration management via Puppet ➢ Automate repetitive task and quickly deploy applications ➢ Monitoring ➢ Ability to create Trends and Charts on given data ➢ Reports from Puppet run ➢ More reporting via plugins: ABRT and Openscap
- 5. Distributed Architecture ➢ SmartProxies located locally on Foreman itself or independent – used for orchestration of DNS, DHCP, etc. ➢ To manage whole infrastructure from one central place when its distributed over different locations
- 7. Compute Resources ➢ ForemanOffers a unified interface to all major compute-providers ➢ Uses Ruby Library 'Fog' to abstract the communication details from all supported compute-resources ➢ Uses Host-groups to describe OS and puppet-config ➢ Supported Compute-resources are ➢ Libvirt ➢ Ovirt ➢ Openstack ➢ Vmware ➢ Docker ➢ EC2
- 8. Hostgroups ➢ Hostgroup containsdefinition of operating system, puppet configuration and compute-profile ➢ This helps when provisioning multiple hosts with same properties like (OS, arch, media etc)
- 9. API & CLI ➢Full RESTful API ➢ Docs at http://foreman.example.com/apidoc on your Foreman server ➢ Hammer CLI ➢ Easy to use, great for working in shell ➢ Automating stuff to perform bulk operations easily
- 10. Plugins More Info: http://projects.theforeman.org/projects/foreman/wiki/List_of_Plugins Richecosystem of existing plugins
- 11. Discovery ➢ Metal asa Service
- 12. Discovery ➢ http://theforeman.org/plugins/foreman_discovery/2.0/ ➢ Unknownhost boots via DHCP/PXE to a ramdisk ➢ Becomes available in Foreman as a “Discovered Host” ➢ Report hardware capabilities (Memory, CPU, disk etc) ➢ Provision with as few as NO clicks ➢ Automatic provisioning via rules on arbitrary facts: ➢ cpu_count < 8 → web server host group ➢ cpu_count >= 8 → db box host group
- 13. Katello ➢ Brings ContentLifecycle Management ➢ Sync RPM, Docker, and Puppet content ➢ Spin repositories with filters using Content Views
- 14. Content Sources ➢ DirectUpload ➢ Sync External Sources ➢ YUM Repositories ➢ Puppet forges ➢ Docker registries ➢ Red Hat CDN(w/ subscription manifest)
- 15. Content-view ➢ Manages theapplication life-cycle ➢ Dev → QA → Production ➢ User can set filters ➢ Filters allows to customize the contents to be made available to client host
- 16. Default Organization View ➢Simplest View ➢ Available by default ➢ Everything you've synced is visible
- 17. OS Repo App Repo PuppetModules Filters Publish Publish Version 1.0 Selected Puppet Modules Custom Content Views ➢ Add repositories ➢ Add filters ➢ Publish a version (snapshot) of the Content View and it becomes available in the Library
