A sample project for event-driven microservices built with FastAPI and Kafka pub/sub
This project supports docker-compose and kubernetes with minikube
All services required to run the project have been dockerized and can be initiated with the generic docker-compose up, as seen below:
$ COMPOSE_DOCKER_CLI_BUILD=1 DOCKER_BUILDKIT=1 docker-compose up -d --build # Use Docker Buildkit for multi-stage builds$ minikube start
😄 minikube v1.27.0 on Ubuntu 20.04
❗ Kubernetes 1.25.0 has a known issue with resolv.conf. minikube is using a workaround that should work for most use cases.
❗ For more information, see: https://github.com/kubernetes/kubernetes/issues/112135
