The document presents Uyuni, a systems management solution designed for managing Linux infrastructure efficiently through automation and reporting capabilities. It is a fork of Spacewalk, offering features like configuration management, virtualization, and compliance management, while supporting various operating systems. Uyuni aims to build community involvement and continuously improve usability and functionality for managing on-prem, cloud, and hybrid systems.

7. Uyuni: fork of Spacewalk
 Simple installation
 Two stacks: traditional client (“spacewalk”) and Salt
 New development goes into Salt clients (“minions”)
 Traditional stack lets you continue using your Spacewalk/Satellite stack and knowledge in Uyuni. No need to convert to Salt.
 Containers/Kubernetes integration
 Scalability
 Usability
 React Web UI
 Python 3 and JDK11 codebase

8.  System deployment
 Patch management
 Service Pack migration
 Configuration management
 Bare-metal provisioning
 Schedule action chains to be performed on systems
 Compliance management: OpenSCAP and CVE Audit! Get alerts and fix in 1-click!
 API
Features

9.  Transparent integration with Salt
 Manage on-prem, cloud, hybrid cloud or multi-cloud systems
 Content Lifecycle Management: define stages (DEV, TEST, PRO) for your software channels
and apply filters to add/remove contents and create new channels
 Recurring actions
 Build OS and container images
 Compliance: CVE audit, SCAP, subscription matching
 Virtualization management
 Monitoring (Prometheus & Grafana stack), including federation
 Formulas with Forms: create YAML automation templates, no programming skills required!
Cool features!

10.  Public repository and public development: upstream first policy
 Mailing lists, IRC, Gitter
 (Semi) Public CI
 Base OS: openSUSE LLeap 15.1

14. Uyuni installation

15. Install Uyuni
 From scratch:
 Install openSUSE Leap 15.1
 Add Uyuni repository
 zypper in patterns-uyuni_server
 Or as an appliance you can download from:
https://build.opensuse.org/project/show/home:pagarcia:Uyuni:2020.04
15

16. Setup Uyuni
# yast2
 Go to Network Services > Uyuni Setup and answer a few
questions
Important! You need a FQDN or the clients will not be able to connect
Example configuration for a lab: https://github.com/uyuni-project/uyuni/wiki/Libvirt-DNS-and-DHCP-without-Avahi
16

17. openSUSE Leap with Uyuni

18. Add openSUSE Leap channels
# zypper in spacewalk-utils
# spacewalk-common-channels -l | grep leap15_1
# spacewalk-common-channels -a x86_64 opensuse_leap15_1
opensuse_leap15_1-updates opensuse_leap15_1-uyuni-client
# spacewalk-repo-sync -c “opensuse_leap15_1*”
# mgr-create-bootstrap-repo -f --with-custom-channels openSUSE-Leap-

19. Onboard openSUSE clients
 Create activation key
 Register clients using one of three methods:
— Web UI (easiest)
— Bootstrap script (massive onboarding, customization during
onboarding)
— Manually (install Salt minion, accept key in Server)
19

20. Patches
 The openSUSE Leap Updates repository includes patch
information
 Uyuni will use it for Patches and Audit
20

21. openSUSE Leap supported features

Initial Configuration”
 Available for free for a limited time (COVID-19) in the “SUSE Technical Product Training” YouTube channel
 Installation, configuration, channels, activation keys, content lifecycle management, etc
 Use spacewalk-common-channels instead of SCC subscription to add products
