The config.yaml file has the configuration for the fully functioning Nameko. First, we inform Nameko of the access route to the message broker, in this case, the RabbitMQ:

AMQP_URI: 'amqp://guest:guest@rabbitmq'

Then, we pass the route to access the database, thus allowing the dependency injection by Nameko:

 
DB_URIS: 
    "command_famous:Base": ${COMMANDDB_DEV_HOST} 
 

The next setting refers to the logging level that should be used by our application:

LOGGING: 
    version: 1 
    handlers: 
        console: 
            class: logging.StreamHandler 
    root: 
        level: DEBUG 
        handlers: [console] 

The complete config.yaml file has the following configuration:

AMQP_URI: 'amqp://guest:guest@rabbitmq' 
 
DB_URIS: 
    "command_famous:Base": ${COMMANDDB_DEV_HOST} 
 
LOGGING: 
    version: 1 
    handlers: 
        console: 
            class: logging.StreamHandler 
    root: 
        level: DEBUG 
        handlers: [console]
