A minimalist implementation of a banking server, exposing endpoints for the following purposes:

• creating a banking customer
• creating an account for a particular customer using one of the accepted currencies
• transfering money between customer accounts
• retrieving all accounts created by the customer in the current session
• retrieving one account created by the customer in the current session

go runGatewayServer(config, store)
runGrpcServer(config, store)

• Comment out the environment variables for docker environment and uncomment the ones for localhost in app.env file.
• Download all dependencies

 go mod download

• Start postgresql server

make postgres PG_CONTAINER_NAME=<name>
