There are two different ideas that are not to be confused with each other. There is the Redis server itself, and then a component’s connection to Redis. The ‘SICRedis’ class is a components component's connection to Redis. The Redis server itself is ran with the redis-server command and has a configuration defined in redis.conf.
Redis server
The IP can be set using export DB_IP=192.168.0.181.
Defaults to localhost.
Messages and requests
A component can implement two callbacks, on_message() and on_request().
A request must be met with a reply
Redis channel specification
output channel format:
{name}:{ip} e.g. DialogflowService:192.168.0.181
request-reply channel format:
{name}:reqreply:{ip} e.g. DialogflowService:reqreply:192.168.0.181
Knowing the IP of the device and the service we expect is running, the request reply channel and output channel are known. Using the request reply channel we can request the component to start listening to input channels (using a ConnectRequest).
