## Docker settings

By default, there are 4 CPU cores allocated: core 0 for monitoring, core 1 for database (MariaDB), and cores 2 and 3 for Keycloak server.
Default memory limits for database and Keycloak server are 2g. The `cpuset` and `memlimit` parameters set here are set to `cpuset` and
`mem_limit` parameters of docker-compose configuration. See docker-compose documentation for meaning of the values. How to set the parameters
correctly depends on number of factors - number of cpu cores, NUMA, available memory etc., hence it is out of scope of this document.
