Uyuni is a software-defined infrastructure and configuration management solution. It bootstraps physical servers, creates VMs for virtualization and cloud, deploys and updates packages -even with content lifecycle management features-, builds container images, and tracks what runs on your Kubernetes clusters. All using Salt under the hood. This presentation at the openSUSE Virtual Summit 2020 discusses what is Uyuni, where we are, what's next and opportunities for the community.

5. Origins: Spacewalk
 Free & Open Source Systems Management
 Around since 2008
 Base for Red Hat Satellite 5 and SUSE Manager <= 3.2
 Maintenance mode:
 No modern configuration management
 No clear plans for the future EOL: May 2020 (next month!)

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
7

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
8

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)

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