DCImanager 6 structure

The architecture of DCImanager 6 is based on the use of Docker. The Docker technology allows to create and manage containers. A docker container is an isolated environment in which the application is running. DCImanager 6 uses the docker-compose service to manage all docker containers. The required environment is configured in the /opt/ispsystem/dci/docker-compose.yaml file.
