Quality assurance of RHEL systems with a high level of security
Javorský, Lukáš ; Matěj,, Týč (oponent) ; Sedlák, Petr (vedoucí práce)
The aim of this thesis is to develop a quality assurance pipeline for RHEL operating systems with security hardening. This thesis is driven by the desire to develop a user-friendly testing environment for quality engineers, allowing them to easily verify the functionality of system packages in security security-hardened testing environment. The achievable outcome was realized by the integration of Red Hat's existing software portfolio, namely Image Builder, and OpenSCAP, resulting in the establishment of pre-hardened virtual machines. Subsequently, integration with Red Hat's test management application Testing Farm, serves to simplify virtual image provisioning and providing an established testing pipeline.

Operator for MariaDB Galera Cluster in OpenShift
Javorský, Lukáš ; Malinka, Kamil (oponent) ; Januš, Filip (vedoucí práce)
The main goal of this thesis is to create an orchestrated system, that will adapt and react to the current database server load. The newest OpenShift 4 orchestration and container deployment platform, which is built on top of the Kubernetes API, is being used as a~solution to this problem. Using the operator as the mind of the OpenShift cluster, responsible for the deployment, load balancing, detecting crashes, and fail-over recovery in the MariaDB containers, we can ensure that the database will keep functioning, even in the highest peaks throughout the day. Galera replication software built into each MariaDB server ensures that the content of every database in the Galera cluster is consistent.
