microservices-demo VS mainflux

As an inbetween beginner and advanced you can look at this project - https://microservices-demo.github.io/ its more practical and again uses Python.

I'm new to kubernetes world. I got sample kubernetes deployments (like sock-shop) working end-to-end without any issues. I tried NodePort to access the service but instead of running it on a different port I need to run it exact port 80 on the host. I tried many ingress solutions but didn't work.

Here's an example app that fits all of the criteria above. Can be used as a good reference point. https://github.com/microservices-demo/microservices-demo

1) Deploy the Sock Shop app in our K8s cluster. While we’ll use Sock Shop as our example application, you can deploy your own app to your cluster and still follow along. 2) Deploy APIClarity in our K8s cluster and configure monitoring 3) Observe API traffic on the APIClarity dashboard 4) Review and create an API specification and view the generated OpenAPI spec in Swagger format. 5) Identify deviations from an API spec along with usage of shadow and zombie APIs. 6) View and filter API events

Depending on what you want there is Microservice demo from Google or Sock Shop from Weaveworks.

There are sample application that you could deploy, for example https://github.com/microservices-demo/microservices-demo

For something more advanced you can look at this example but this is very advanced, its from an IoT platform written in Golang - https://github.com/mainflux/mainflux

There is lots of software to choose from, I suggest you have a look at Mainflux, and Mosquitto is popular for broker. Thingsboard is a turnkey solution, it's nice in some ways, but also very slow and heavy. Other options to research in this wikipedia article.
