Singularity VS microservices-demo

The real gem of the Mesos ecosystem was the much lesser known Singularity scheduler from HubSpot.

https://github.com/HubSpot/Singularity

I've run this at scale, in production since 2015 and it has been absolutely rock solid and does most of the production things you'd want. Unlike commercial products, it was written to run HubSpot's own infrastructure so it does what a production system needs. Really bummed to have to downgrade to something like K8s in the near future.

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
