-------------------------------------------------------------------------------- 1 | # Cymbal Shops Branding 2 | 3 | By default, when you deploy this sample app, the "Online Boutique" branding (logo and wording) will be used. 4 | But you may want to use Google Cloud's fictitious company, _Cymbal Shops_, instead. 5 | 6 | To use "Cymbal Shops" branding, set the `CYMBAL_BRANDING` environment variable to `"true"` in the the Kubernetes manifest (`.yaml`) for the `frontend` Deployment. 7 | 8 | ``` 9 | apiVersion: apps/v1 10 | kind: Deployment 11 | metadata: 12 | name: frontend 13 | spec: 14

-------------------------------------------------------------------------------- /docs/development-principles.md: -------------------------------------------------------------------------------- 1 | # Development Principles 2 | 3 | > **Note:** This document outlines guidances behind some development decisions 4 | > behind the Online Boutique demo application. 5 | 6 | ### Minimal configuration 7 | 8 | Running the demo locally or on GCP should require minimal to no 9 | configuration unless absolutely necessary to run critical parts of the demo. 10 | 11 | Configuration that takes multiple steps, especially such as creating service 12 | accounts should be avoided. 13 | 14 | ### Microservice implementations should not be complex 15 | 16 | Each service should provide a minimal implementation and try to avoid 17 | unnecessary code and logic that's not executed. 18 | 19 | Keep in mind that any service implementation is a decent example of “a GRPC 20 | application that runs on Kubernetes”. Keeping the source code short and 21 | navigable will serve this purpose. 22 | 23 | It is okay to have intentional inefficiencies in the code as they help 24 | illustrate the capabilities of profiling and diagnostics offerings. 25 | -------------------------------------------------------------------------------- /docs/img/architecture-diagram.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/go-micro/demo/b09ae408195d72a7a6985d633a0b025a1b8e35bd/docs/img/architecture-diagram.png -------------------------------------------------------------------------------- /docs/img/jaeger-dependencies.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/go-micro/demo/b09ae408195d72a7a6985d633a0b025a1b8e35bd/docs/img/jaeger-dependencies.png -------------------------------------------------------------------------------- /docs/img/memorystore.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/go-micro/demo/b09ae408195d72a7a6985d633a0b025a1b8e35bd/docs/img/memorystore.png -------------------------------------------------------------------------------- /docs/img/online-boutique-frontend-1.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/go-micro/demo/b09ae408195d72a7a6985d633a0b025a1b8e35bd/docs/img/online-boutique-frontend-1.png -------------------------------------------------------------------------------- /docs/img/online-boutique-frontend-2.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/go-micro/demo/b09ae408195d72a7a6985d633a0b025a1b8e35bd/docs/img/online-boutique-frontend-2.png -------------------------------------------------------------------------------- /docs/network-policies/network-policy-adservice.yaml: -------------------------------------------------------------------------------- 1 | # Copyright 2022 Google LLC 2 | # 3 | # Licensed under the Apache License, Version 2.0 (the "License");

See the following instructions for Istio steps. 6 | 7 | ## Steps 8 | 9 | 1. Create a GKE cluster with at least 4 nodes, machine type `e2-standard-4`. 10 | 11 | ``` 12 | PROJECT_ID="" 13 | ZONE="" 14 | 15 | gcloud container clusters create onlineboutique \ 16 | --project=${PROJECT_ID} --zone=${ZONE} \ 17 | --machine-type=e2-standard-4 --num-nodes=4 18 | ``` 19 | 20 | 2. [Install Istio](https://istio.io/latest/docs/setup/getting-started/) on your cluster. 21 | 22 | 3. Enable Istio sidecar proxy injection in the `default` Kubernetes namespace. 23 | 24 | ```sh 25 | kubectl label namespace default istio-injection=enabled 26 | ``` 27 | 28 | 4. Apply all the manifests in the `/release` directory. This includes the Istio and Kubernetes manifests. 29 | 30 | ```sh 31 | kubectl apply -f ./release 32 | ``` 33 | 34 | 5. Run `kubectl get pods` to see pods are in a healthy and ready state. 35 | 36 | 6. Find the IP address of your Istio gateway Ingress or Service, and visit the 37 | application frontend in a web browser. 38 | 39 | ```sh 40 | INGRESS_HOST="$(kubectl -n istio-system get service istio-ingressgateway \ 41 | -o jsonpath='{.status.loadBalancer.ingress[0].ip}')" 42 | echo "$INGRESS_HOST" 43 | ``` 44 | 45 | ```sh 46 | curl -v "http://$INGRESS_HOST" 47 | ``` 48 | 49 | 50 | ## Additional service mesh demos using OnlineBoutique 51 | 52 | - [Canary deployment](https://github.com/GoogleCloudPlatform/istio-samples/tree/master/istio-canary-gke) 53 | - [Security (mTLS, JWT, Authorization)](https://github.com/GoogleCloudPlatform/istio-samples/tree/master/security-intro) 54 | - [Cloud Operations (Stackdriver)](https://github.com/GoogleCloudPlatform/istio-samples/tree/master/istio-stackdriver) 55 | - [Stackdriver metrics (Open source Istio)](https://github.com/GoogleCloudPlatform/istio-samples/tree/master/stackdriver-metrics) 56 | 57 | -------------------------------------------------------------------------------- /go.work: -------------------------------------------------------------------------------- 1 | go 1.19 2 | 3 | use ( 4 | ./service/ad 5 | ./service/cart 6 | ./service/checkout 7 | ./service/currency 8 | ./service/email 9 | ./service/frontend 10 | ./service/payment 11 | ./service/productcatalog 12 | ./service/recommendation 13 | ./service/shipping 14 | ) 15 | -------------------------------------------------------------------------------- /go.work.sum: -------------------------------------------------------------------------------- 1 | github.com/stretchr/objx v0.4.0/go.mod h1:YvHI0jy2hoMjB+UWwv71VJQ9isScKT/TqJzVSSt89Yw= 2 | github.com/stretchr/testify v1.8.0/go.mod h1:yNjHg4UonilssWZ8iaSj1OCr/vHnekPRkoO+kdMU+MU= 3 | github.com/urfave/cli v1.22.4 h1:u7tSpNPPswAFymm8IehJhy4uJMlUuU/GmqSkvJ1InXA= 4 | gopkg.in/yaml.v3 v3.0.1/go.mod h1:K4uyk7z7BCEPqu6E+C64Yfv1cQ7kz7rIZviUmN+EgEM= 5 | -------------------------------------------------------------------------------- /infra/istio/allow-egress-googleapis.yaml: -------------------------------------------------------------------------------- 1 | # Copyright 2018 Google LLC 2 | # 3 | # Licensed under the Apache License, Version 2.0 (the "License");
