-## Docker usage
-
-**start platform using docker:**
-- install docker
-- cd to 'docker' folder
-- create folder for cassandra data directory on your local env (host)
-  - `mkdir /home/user/data_dir`
-- modify .env file to point to the directory created in previous step
-- start ./deploy.sh script to run all the services
-
-
-**start-up for local development** 
-
-cassandra with thingsboard schema (9042 and 9061 ports are exposed).  
-zookeper services (2181 port is exposed).  
-9042, 9061 and 2181 ports must be free so 'Thingsboard' server that is running outside docker container is able to connect to services.  
-you can change these ports in docker-compose.static.yml file to some others, but 'Thingsbaord' application.yml file must be updated accordingly.    
-if you would like to change cassandra port, change it to "9999:9042" for example and update cassandra.node_list entry in application.yml file to localhost:9999.
