A prototype microservice for message passing using Redis and the Pubsub Pattern

pubsub

Novel implementation of the publisher/subscription design pattern, in RustLang

Two applications:

1. publisher : connects to a Redis instance and publishes a message to the stats channel then terminates

2. subscriptor : connects to a Redis instance and subscribes to the stats channel queue to listen and handle messages asynchronously. prints message payloads when receieved.

Building / test

PreReqs:

1. must have a running redis server on your host, or in a container
2. Podman must be installed

To build either app, subscriptor as example:

1. cd subscriptor
2. podman build . -t redis-sub:latest

To Run and connect to redis server on host network:

1. podman run --net=host redis-sub:latest

If done correctly you will get the following output:

service started
connected to queue

likewise after starting redis-pub you should see:

service started
published

and the subscriptor will handle the published message:

Message { id: "13a22505cf7f448b98a13fc4358c326e", channel: "stats", payload: "Ping" }

where id is a randomly generated uuid
