## Installation
> **Note:** that the first build can take up to 20-30 minutes. Consequent builds
> will be faster.
We offer three installation methods:
1. **Running locally with “Docker for Desktop”** (~20 minutes) You will build
and deploy microservices images to a single-node Kubernetes cluster running
on your development machine.
2. **Running on Google Kubernetes Engine (GKE)”** (~30 minutes) You will build,
upload and deploy the container images to a Kubernetes cluster on Google
Cloud.
3. **Using pre-built container images:** (~10 minutes, you will still need to
follow one of the steps above up until `skaffold run` command). With this
option, you will use pre-built container images that are available publicly,
instead of building them yourself, which takes a long time).

1. Install tools to run a Kubernetes cluster locally:
- kubectl (can be installed via `gcloud components install kubectl`)
- Docker for Desktop (Mac/Windows): It provides Kubernetes support as [noted
here](https://docs.docker.com/docker-for-mac/kubernetes/).
- [skaffold](https://github.com/GoogleContainerTools/skaffold/#installation)
- [skaffold](https://skaffold.dev/docs/getting-started/#installing-skaffold)
(ensure version ≥v0.20)
1. Launch “Docker for Desktop”. Go to Preferences and choose “Enable Kubernetes”.

1. Install tools specified in the previous section (Docker, kubectl, skaffold)
1. Create a Google Kubernetes Engine cluster and make sure `kubectl` is pointing
to the cluster.

`docker` CLI to authenticate to GCR:
```sh
gcloud services enable containerregistry.googleapis.com
```
```sh
gcloud auth configure-docker -q
```
3. Set your project ID on image names:
1. In the root of this repository, run `skaffold run --default-repo=gcr.io/[PROJECT_ID]`,
where [PROJECT_ID] is your GCP project ID.
- Edit `skaffold.yaml`, update the `imageName:` fields that look like
`gcr.io/[PROJECT_ID]` with your own GCP project ID.
This command:
- Similarly, edit all Kubernetes Deployment manifests in the
[`./kubernetes-manifests`](./kubernetes-manifests) directory. Find the
`image:` fields with `gcr.io/[...]` and change them to your own GCP project
ID.
5. Run `skaffold run` from the root of this repository. This command:
- builds the container images
- pushes them to GCR
- applies the `./kubernetes-manifests` deploying the application to
Kubernetes.
6. Find the IP address of your application, then visit the application on your
**Troubleshooting:** If you get "No space left on device" error on Google
Cloud Shell, you can build the images on Google Cloud Build: [Enable the

API](https://console.cloud.google.com/flows/enableapi?apiid=cloudbuild.googleapis.com),
then run `skaffold run -p gcb --default-repo=gcr.io/[PROJECT_ID]` instead.
1. Find the IP address of your application, then visit the application on your
browser to confirm installation.
kubectl get service frontend-external
### (Optional) Deploying on a Istio-installed cluster
**Troubleshooting:** A Kubernetes bug (will be fixed in 1.12) combined with
a Skaffold [bug](https://github.com/GoogleContainerTools/skaffold/issues/887)
causes load balancer to not to work even after getting an IP address. If you
are seeing this, run `kubectl get service frontend-external -o=yaml | kubectl apply -f-`
to trigger load balancer reconfiguration.
### Option 3: Using Pre-Built Container Images
> 💡 Recommended if you want to deploy the app faster in fewer steps to an
> existing cluster.
**NOTE:** If you need to create a Kubernetes cluster locally or on the cloud,
follow "Option 1" or "Option 2" until you reach the `skaffold run` step.
This option offers you pre-built public container images that are easy to deploy
by deploying the [release manifest](./release) directly to an existing cluster.
**Prerequisite**: a running Kubernetes cluster (either local or on cloud).
1. Clone this repository, and go to the repository directory
1. Run `kubectl apply -f ./release/kubernetes-manifests.yaml` to deploy the app.
1. Run `kubectl get pods` to see pods are in a Ready state.
1. Find the IP address of your application, then visit the application on your
browser to confirm installation.
```sh
kubectl get service/frontend-external
```
### (Optional) Deploying on a Istio-installed GKE cluster
> **Note:** you followed GKE deployment steps above, run `skaffold delete` first
> to delete what's deployed.
1. Create a GKE cluster.
1. Create a GKE cluster (described in "Option 2").
2. Install Istio **without mutual TLS** option. (Istio mTLS is not yet supported
on this demo.)
1. Use [Istio on GKE add-on](https://cloud.google.com/istio/docs/istio-on-gke/installing)
to install Istio to your existing GKE cluster.
3. Install the automatic sidecar injection (annotate the `default` namespace
```sh
gcloud beta container clusters update demo \
--zone=us-central1-a \
--update-addons=Istio=ENABLED \
--istio-config=auth=MTLS_PERMISSIVE
```
> NOTE: If you need to enable `MTLS_STRICT` mode, you will need to update
> several manifest files:
>
> - `kubernetes-manifests/frontend.yaml`: delete "livenessProbe" and
> "readinessProbe" fields.
> - `kubernetes-manifests/loadgenerator.yaml`: delete "initContainers" field.
1. (Optional) Enable Stackdriver Tracing/Logging with Istio Stackdriver Adapter
by [following this guide](https://cloud.google.com/istio/docs/istio-on-gke/installing#enabling_tracing_and_logging).
1. Install the automatic sidecar injection (annotate the `default` namespace
with the label):
```sh
kubectl label namespace default istio-injection=enabled
```
4. Apply the manifests in [`./istio-manifests`](./istio-manifests) directory.
1. Apply the manifests in [`./istio-manifests`](./istio-manifests) directory.
(This is required only once.)
```sh
kubectl apply -f ./istio-manifests
```
This is required only once.
1. Deploy the application with `skaffold run --default-repo=gcr.io/[PROJECT_ID]`.
5. Deploy the application with `skaffold run`.
1. Run `kubectl get pods` to see pods are in a healthy and ready state.
6. Run `kubectl get pods` to see pods are in a healthy and ready state.
7. Find the IP address of your istio gateway Ingress or Service, and visit the
1. Find the IP address of your Istio gateway Ingress or Service, and visit the
application.
INGRESS_HOST="$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.status.loadBalancer.ingress[0].ip}')"
```sh
INGRESS_HOST="$(kubectl -n istio-system get service istio-ingressgateway \
-o jsonpath='{.status.loadBalancer.ingress[0].ip}')"
echo "$INGRESS_HOST"
```
```sh
curl -v "http://$INGRESS_HOST"
```
### Cleanup
If you've deployed the application with `skaffold run` command, you can run
`skaffold delete` to clean up the deployed resources.
If you've deployed the application with `kubectl apply -f [...]`, you can
run `kubectl delete -f [...]` with the same argument to clean up the deployed
resources.

# Development Principles
> **Note:** This document outlines guidances behind some development decisions
> behind the Hipster Shop demo application.
### Minimal configuration
Running the demo locally or on GCP should require minimal to no
configuration unless absolutely necessary to run critical parts of the demo.
Configuration that takes multiple steps, especially such as creating service
accounts should be avoided.
### App must work well outside GCP
Demo application should work reasonably well when it is not deployed to GCP
services. The experience of running the application locally or on GCP should
be close.
For example:
- OpenCensus prints the traces to stdout when it cannot connect to GCP.
- Stackdriver Debugging tries connecting to GCP multiple times, eventually gives
up.
### Running on GCP must not reduce functionality
Running the demo on the GCP must not reduce/lose any of the capabilities
developers have when running locally.
For example: Logs should still be printed to stdout/stderr even though logs are
uploaded to Stackdriver Logging when on GCP, so that developers can use "kubectl
logs" to diagnose each container.
### Microservice implementations should not be complex
Each service should provide a minimal implementation and try to avoid
unnecessary code and logic that's not executed.
Keep in mind that any service implementation is a decent example of “a GRPC
application that runs on Kubernetes”. Keeping the source code short and
navigable will serve this purpose.
It is okay to have intentional inefficiencies in the code as they help
illustrate the capabilities of profiling and diagnostics offerings.

## `hack/`
This directory provides scripts for building and pushing Docker images, and tagging new demo
releases.
### env variables
- `TAG` - git release tag / Docker tag.
- `REPO_PREFIX` - Docker repo prefix to push images. Format: `$user/$project`. Resulting images will be of the
format `$user/$project/$svcname:$tag` (where `svcname` = `adservice`, `cartservice`,
etc.)
### scripts
1. `./make-docker-images.sh`: builds and pushes images to the specified Docker repository.
2. `./make-release-artifacts.sh`: generates a combined YAML file with image $TAG at:
`./release/kubernetes-manifests/demo.yaml`.
3. `./make-release.sh`: runs scripts 1 and 2, then runs `git tag` / pushes updated manifests to master.

## Dynamic catalog reloading / artificial delay
This service has a "dynamic catalog reloading" feature that is purposefully
not well implemented. The goal of this feature is to allow you to modify the
`products.json` file and have the changes be picked up without having to
restart the service.
However, this feature is bugged: the catalog is actually reloaded on each
request, introducing a noticeable delay in the frontend. This delay will also
show up in profiling tools: the `parseCatalog` function will take more than 80%
of the CPU time.
You can trigger this feature (and the delay) by sending a `USR1` signal and
remove it (if needed) by sending a `USR2` signal:
```
# Trigger bug
kubectl exec \
$(kubectl get pods -l app=productcatalogservice -o jsonpath='{.items[0].metadata.name}') \
-c server -- kill -USR1 1
# Remove bug
kubectl exec \
$(kubectl get pods -l app=productcatalogservice -o jsonpath='{.items[0].metadata.name}') \
-c server -- kill -USR2 1
```
## Latency injection
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
to the server.
For example, use `EXTRA_LATENCY="5.5s"` to sleep for 5.5 seconds on every request.
