Sock Shop : A Microservice Demo Application

The application is the user-facing part of an online shop that sells socks. It is intended to aid the demonstration and testing of microservice and cloud native technologies.

It is built using Spring Boot, Go kit and Node.js and is packaged in Docker containers.

This repository is a multiarchitecture compute version of the microservices demonstration.

Purpose

The purpose of this application is to use a reference microservices demo to show a real-life multiarchitecture compute.

Applications

1. front-end
2. orders
3. payment
4. user user-db is Intel only. The power overlay supports ppc64le.
5. catalogue catalogue-db is Intel only. The power overlay supports ppc64le.
6. cart
7. shipping
8. queue-master

The catalogue and user have a built-in wait to READY as the dependent databases are started up.

Unless mentioned, each image is cross-compiled in s390x, amd64, arm64, and ppc64le. The image is manifest-listed.

Deployment

There are three diferent kustomizations: fyre, multi, multi-hpa. multi-hpa is a HoriztonalPodAutoScaler version where the front-end autoscales.

fyre

To deploy to fyre, use the following:

1. Update manifests/overlays/fyre/env.secret with username and password:

username=
password=

2. Build sock shop for fyre:

❯ kustomize build manifests/overlays/fyre | oc apply -f - 

3. Destroy sock shop for fyre:

❯ kustomize build manifests/overlays/fyre | oc delete -f - 

multiarch compute

To deploy to a multiarch compute cluster, use the following:

1. Update manifests/base/env.secret with username and password:

username=
password=

2. Build sock shop for multi:

❯ kustomize build manifests/overlays/multi | oc apply -f - 

3. Destroy sock shop for multi:

❯ kustomize build manifests/overlays/multi | oc delete -f - 

Using the application

1. Get the route to the host

❯ oc get routes -n sock-shop
NAME        HOST/PORT                                                 PATH   SERVICES    PORT   TERMINATION   WILDCARD
sock-shop   sock-shop.apps.demo.xyz          front-end   8079   edge/None     None

2. Navigate to https://sock-shop.apps.demo.xyz

3. Pick a test user from User Accounts

Have fun and use it.

Images

The applications are compiled into images that are hosted at quay.io/repository/powercloud. There is a manifest-listed image for each application in the corresponding sock-shop repository.

To build the images, use:

amd64

ARCH=amd64
REGISTRY=quay.io/repository/powercloud/sock-shop-${APP}
make cross-build-amd64

All other arches

ARCH=ppc64le
REGISTRY=quay.io/repository/powercloud/sock-shop-${APP}
make cross-build-amd64

To push the manifest-listed images, use:

REGISTRY=quay.io/repository/powercloud/sock-shop-${APP}
ARM_REGISTRY=quay.io/repostiroy/powercloud/sock-shop-${APP}
APP=front-end
make push-ml

Development

The following custom repos are used:

• front-end - https://github.com/ocp-power-demos/sock-shop-front-end
• user - https://github.com/ocp-power-demos/sock-shop-user
• orders - https://github.com/ocp-power-demos/sock-shop-orders

Using

Please login in via the https route to sock-shop and register a new user.

Testing the Multiarchitecture Compute
