*	**MONGO_INITDB_ROOT_PASSWORD** - пароль привилегированного пользователя
*	**MONGO_INITDB_DATABASE** - определение базы данных, используемой в скриптах развертывания в ``/docker-entrypoint-initdb.d/*.js/sh. (1)``
*	**ECOS_HISTORY_APP_DATASOURCE_DATABASE** - db микросервиса истории **(ecos-history)**
*	**ECOS_HISTORY_APP_DATASOURCE_USERNAME** - логин для мкр истории, роль dbOwner **(ecos-history)**
*	**ECOS_HISTORY_APP_DATASOURCE_PASSWORD** - пароль для мкр истории **(ecos-history-password)**
*	**ECOS_PROCESS_APP_DATASOURCE_DATABASE** - db микросервиса ecos-process **(ecos-process)**
*	**ECOS_PROCESS_APP_DATASOURCE_USERNAME **- логин для мкр ecos-process, роль dbOwner **(ecos-process)**
*	**ECOS_PROCESS_APP_DATASOURCE_PASSWORD** - пароль для мкр ecos-process **(ecos-process-password)**
 	
(1) - This variable allows you to specify the name of a database to be used for creation scripts in /docker-entrypoint-initdb.d/.js (see Initializing a fresh instance below). MongoDB is fundamentally designed for «create on first use», so if you do not insert data with your JavaScript files, then no database is created.
