# Microservices demo
|
||||
|
||||
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.
|
||||
|
||||
### Setup on GKE
|
||||
|
||||
1. Install:
|
||||
|
||||
- [gcloud](https://cloud.google.com/sdk/) + sign in to your account/project.
|
||||
- kubectl (can be installed via `gcloud components install kubectl`)
|
||||
- Docker (on Mac/Windows, install Docker for Desktop CE)
|
||||
- [Skaffold](https://github.com/GoogleContainerTools/skaffold/#installation)
|
||||
|
||||
1. Create a Google Kubernetes Engine cluster and make sure `kubectl` is pointing
|
||||
to the cluster.
|
||||
|
||||
1. Enable Google Container Registry (GCR) on your GCP project:
|
||||
|
||||
gcloud services enable containerregistry.googleapis.com
|
||||
|
||||
1. Configure docker to authenticate to GCR:
|
||||
|
||||
gcloud auth configure-docker -q
|
||||
|
||||
1. Edit `skaffold.yaml`, prepend your GCR registry host (`gcr.io/YOUR_PROJECT/`)
|
||||
to all `imageName:` fields.
|
||||
|
||||
1. Edit the Deployment manifests at `kubernetes-manifests` directory and update
|
||||
the `image` fields to match the changes you made in the previous step.
|
||||
|
||||
1. Run `skaffold run`. This builds the container
|
||||
images, pushes them to GFR, and deploys the application to Kubernetes.
|
||||
|
||||
1. Find the IP address of your application:
|
||||
|
||||
kubectl get service frontend-external
|
||||
|
||||
then visit the application on your browser to confirm
|
||||
installation.
