Czech title
Operátor pro MariaDB Galera v prostředí OpenShift

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.
