Egkatastasis is an open source testing system for openSUSE container images. It installs and tests packages within containers to check for issues, using Docker and systemd-nspawn. Tests are isolated, ephemeral, and do not impact the host system. Egkatastasis aims to improve image quality by detecting orphaned packages or packages using the wrong repositories. It provides visualization of installation metrics and logs to analyze test results at scale. The goal is fast, trusted, and simple testing of all packages in openSUSE images.

3. What it means...
● εγκαθιστώ < γκαθίστημι < ν + κατά + στημιἐ ἐ ἵ
● In + to + stallum → Move sth in to a location or medium
● Install → Installation
● Permanent existence (of software) over a medium

4. What is it?

5. ● Egkatastasis is an open source system for testing openSUSE
container images providing basic mechanisms for installation,
log analysis, and metrics visualization of every package
contained into the official repositories.
● Egkatastasis tests production container workloads at scale
using Docker and systemd-nspawn, combined with the best-of-
breed ideas and practices from the community using Filebeat
and Elastic Stack.
● Egkatastasis is hosted by GitHub. If you are interested in
openSUSE and you want to help shape the evolution of testing
openSUSE container images, consider joining our effort by
contributing in any way that feels fun for you.

6. How it started ...

7. ● Bad quality of our images
– Orphaned packages
– Wrong repositories
● OpenQA is kind of overkill
– [gsoc] Investigate/implement container-based backend
● Zero testing in our images
Motivation

8. ● How many packages might be problematic without my knowledge?
● How do we know unless we test all of them?
● How many packages are supported? Can we test all the packages?
● How big untertaking is this?
● How much time is it gonna take?
● How much of resources are going to be needed?
● How difficult is it?
● How accurate the results are going to be?
Trying to answer ...

13. Isolation

14. ● Virtual Machines
● Chroot
● Containers

15. Methodology

16. ● Tests shouldn't influence each other
● Tests should be ephemeral
● Tests should not affect the host OS that they are running
