The system is deployed on 4 containers controlled via The Docker Compose subsystem. The Docker Compose working directory consists of 4 parts:

• postgres
• redis
• nginx
• web

The file docker-compose.yml describes the architecture of the system. Containers interconnect each other via local host network. Each part has 'log', 'init' and some of them 'data' directories inside:

• 'init' is intended for initial scripts and configuration files;
• 'log' contains log files generated by working containers (could be used for Elastic stack issues in the next versions);
• 'data' for the data generated by the working containers.

The SystemD is used for managing Docker compose subsystem.
