# Hipster Shop: Cloud-Native Microservices Demo Application
This repo is a fork of http://go/microservices-demo with modifications to suite the Tetrate Service Bus.
Changes includes :
- using `Zipkin` traces instead of `Jaeger`/`Stackdriver`
- adding HTTP and GRPC metrics where needed
## Changelog
- 20200129
- All Go microservices are updated to use Zipkin and provide a `/metrics` endpoint for metrology
- Loadgenerator can connect to an HTTPS endpoint
## building images
You can build the images using the scripts located in the `hack` folder:
```
# build only one image
TAG=v1.2.3 REPO_PREFIX=my.docker.hub ./hack/make-docker-images-nopush.sh emailservice
# build all images
TAG=v1.2.3 REPO_PREFIX=my.docker.hub ./hack/make-docker-images-nopush.sh
# build all and push to Docker Registry
TAG=v1.2.3 REPO_PREFIX=my.docker.hub ./hack/make-docker-images.sh
```
## Original Project Description
This project contains a 10-tier microservices application. The application is a
web-based e-commerce app called **“Hipster Shop”** where users can browse items,
add them to the cart, and purchase them.
