There are 4 | just a few small guidelines you need to follow. 5 | 6 | ### Fork 7 | 8 | In the interest of keeping this repository clean and manageable, you should 9 | work from a fork. To create a fork, click the 'Fork' button at the top of the 10 | repository, then clone the fork locally using `git clone 11 | git@https://github.com//microservices-demo`. 12 | 13 | You should also add this repository as an "upstream" repo to your local copy, 14 | in order to keep it up to date. You can add this as a remote like so: 15 | 16 | `git remote add upstream https://github.com/signalfx/microservices-demo.git` 17 | 18 | Verify that the upstream exists: 19 | 20 | `git remote -v` 21 | 22 | To update your fork, fetch the upstream repo's branches and commits, then merge 23 | your `main` with upstream's `main`: 24 | 25 | ``` 26 | git fetch upstream 27 | git checkout main 28 | git merge upstream/main 29 | ``` 30 | 31 | Remember to always work in a branch of your local copy, as you might otherwise 32 | have to contend with conflicts in `main`. 33 | 34 | 35 | ## Creating a PR 36 | 37 | Checkout a new branch, make modifications, build locally, and push the branch to your fork 38 | to open a new PR: 39 | 40 | ```shell 41 | $ git checkout -b myfeature 42 | # edit 43 | # verify that all applications are running well and emitting expected telemetry 44 | $ git add . 45 | $ git commit -m "My commit mesage" 46 | $ git push --set-upstream origin myfeature 47 | ``` 48 | -------------------------------------------------------------------------------- /cloudbuild.yaml: -------------------------------------------------------------------------------- 1 | # This configuration file is used to build and deploy the app into a 2 | # GKE cluster using Google Cloud Build. 3 | # 4 | # PREREQUISITES: 5 | # - Cloud Build service account must have role: "Kubernetes Engine Developer" 6 | 7 | # USAGE: 8 | # GCP zone and GKE target cluster must be specified as substitutions 9 | # Example invocation: 10 | # `gcloud builds submit --config=cloudbuild.yaml --substitutions=_ZONE=us-central1-b,_CLUSTER=demo-app-staging .` 11 | 12 | steps: 13 | - id: 'Deploy application to cluster' 14 | name: 'gcr.io/k8s-skaffold/skaffold:v0.20.0' 15 | entrypoint: 'bash' 16 | args: 17 | - '-c' 18 | - > 19 | gcloud container clusters get-credentials --zone=$_ZONE $_CLUSTER; 20 | skaffold run -f=skaffold.yaml --default-repo=gcr.io/$PROJECT_ID; 21 | 22 | # Add more power, and more time, for heavy Skaffold build 23 | timeout: '3600s' 24 | options: 25 | machineType: 'N1_HIGHCPU_8' -------------------------------------------------------------------------------- /docs/development-principles.md: -------------------------------------------------------------------------------- 1 | # Development Principles 2 | 3 | > **Note:** This document outlines guidances behind some development decisions 4 | > behind the Hipster Shop 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 | ### App must work well outside GCP 15 | 16 | Demo application should work reasonably well when it is not deployed to GCP 17 | services. The experience of running the application locally or on GCP should 18 | be close. 19 | 20 | For example: 21 | - OpenCensus prints the traces to stdout when it cannot connect to GCP. 22 | - Stackdriver Debugging tries connecting to GCP multiple times, eventually gives 23 | up. 24 | 25 | ### Running on GCP must not reduce functionality 26 | 27 | Running the demo on the GCP must not reduce/lose any of the capabilities 28 | developers have when running locally. 29 | 30 | For example: Logs should still be printed to stdout/stderr even though logs are 31 | uploaded to Stackdriver Logging when on GCP, so that developers can use "kubectl 32 | logs" to diagnose each container. 33 | 34 | ### Microservice implementations should not be complex 35 | 36 | Each service should provide a minimal implementation and try to avoid 37 | unnecessary code and logic that's not executed. 38 | 39 | Keep in mind that any service implementation is a decent example of “a GRPC 40 | application that runs on Kubernetes”. Keeping the source code short and 41 | navigable will serve this purpose. 42 | 43 | It is okay to have intentional inefficiencies in the code as they help 44 | illustrate the capabilities of profiling and diagnostics offerings. 45 | -------------------------------------------------------------------------------- /docs/img/architecture-diagram.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/signalfx/microservices-demo/57d144651f438e254adb22f952957dfda73d6198/docs/img/architecture-diagram.png -------------------------------------------------------------------------------- /docs/img/online-boutique-frontend-1.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/signalfx/microservices-demo/57d144651f438e254adb22f952957dfda73d6198/docs/img/online-boutique-frontend-1.png -------------------------------------------------------------------------------- /docs/img/online-boutique-frontend-2.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/signalfx/microservices-demo/57d144651f438e254adb22f952957dfda73d6198/docs/img/online-boutique-frontend-2.png -------------------------------------------------------------------------------- /hack/README.md: -------------------------------------------------------------------------------- 1 | ## `hack/` 2 | 3 | This directory provides scripts for building and pushing Docker images, and tagging new demo 4 | releases. 5 | 6 | ### env variables 7 | 8 | - `TAG` - git release tag / Docker tag. 9 | - `REPO_PREFIX` - Docker repo prefix to push images. Format: `$user/$project`. Resulting images will be of the 10 | format `$user/$project/$svcname:$tag` (where `svcname` = `adservice`, `cartservice`, 11 | etc.) 12 | 13 | ### scripts 14 | 15 | 1. `./make-docker-images.sh`: builds and pushes images to the specified Docker repository. 16 | 2. `./make-release-artifacts.sh`: generates a combined YAML file with image $TAG at: 17 | `./release/kubernetes-manifests/demo.yaml`. 18 | 3. `./make-release.sh`: runs scripts 1 and 2, then runs `git tag` / pushes updated manifests to master. 19 | -------------------------------------------------------------------------------- /hack/license_header.txt: -------------------------------------------------------------------------------- 1 | # Copyright 2018 Google LLC 2 | # 3 | # Licensed under the Apache License, Version 2.0 (the "License");

The goal of this feature is to allow you to modify the 7 | `products.json` file and have the changes be picked up without having to 8 | restart the service. 9 | 10 | However, this feature is bugged: the catalog is actually reloaded on each 11 | request, introducing a noticeable delay in the frontend. This delay will also 12 | show up in profiling tools: the `parseCatalog` function will take more than 80% 13 | of the CPU time. 14 | 15 | You can trigger this feature (and the delay) by sending a `USR1` signal and 16 | remove it (if needed) by sending a `USR2` signal: 17 | 18 | ``` 19 | # Trigger bug 20 | kubectl exec \ 21 | $(kubectl get pods -l app=productcatalogservice -o jsonpath='{.items[0].metadata.name}') \ 22 | -c server -- kill -USR1 1 23 | # Remove bug 24 | kubectl exec \ 25 | $(kubectl get pods -l app=productcatalogservice -o jsonpath='{.items[0].metadata.name}') \ 26 | -c server -- kill -USR2 1 27 | ``` 28 | 29 | ## Latency injection 30 | 31 | This service has an `EXTRA_LATENCY` environment variable. This will inject a sleep for the specified [time.Duration](https://golang.org/pkg/time/#ParseDuration) on every call to 32 | to the server. 33 | 34 | For example, use `EXTRA_LATENCY="5.5s"` to sleep for 5.5 seconds on every request. 35 | -------------------------------------------------------------------------------- /src/productcatalogservice/genproto.sh:
