For the convenience of working with the database, you can use the pgcli utility. Migrations are rolled out when the service starts. migrations are located in the ./migrations directory and are created using the goose tool.

$ pgcli "postgresql://docker:docker@localhost:5432/srv_verification_api"

Python client

$ python -m venv .venv
$ . .venv/bin/activate
$ make deps
$ make generate
$ cd pypkg/srv-verification-api
$ python setup.py install
$ cd ../..
$ docker-compose up -d
$ python scripts/grpc_client.py
