@sanjeev_prasad the Docker Compose repo comes with all values pre-configured. There is no need to change any configuration, other than changing the region from EU868 to something else if you want to use a different region. It will also create all databases for you, see https://github.com/brocaar/chirpstack-docker/tree/master/configuration/postgresql/initdb, these scripts are automatically executed at the first docker-compose up
