# Knative demos
This repository contains a collection of demos I use in different technical sessions about Knative (e.g. [Generating Events from Your Internal Systems with Knative](https://www.youtube.com/watch?v=riq0x5xdfNg)). I try to keep these updated as new versions of Knative get released but sometimes I may get behind. Do let me know (issue) if you find something that's not working.
For the complete list of official Knative samples see [docs](https://github.com/knative/docs/tree/master/eventing/samples) repository.
## Setup
To run these samples you need to a Knative cluster. If you don't have one, you can use the quick [setup](setup/) steps for GKE including static IP, custom domain and a few other post install configurations.
> For official documentation on how to install and configure Knative on variety of Kubernetes services see the [Knative install documentation](https://github.com/knative/docs/tree/master/docs/install)
## Demos
Follow these instructions to run the demos in the presentation:
* Deploying a pre-build image
* [Using kubectl](kubectl-deploy/)
* [Using kn CLI](kn-deploy/)
* On-cluster build using Tekton
* [Csharp build using Kaniko](tekton-kaniko-build/)
* [Java/Kotlin/Groovy/Scala build using Jib](tekton-jib-build/)
* Cloud (serverless) builds
* [Build and deploy using GitHub Actions](github-action-deploy/)
* Build and deploy using Cloud Build
* Configuring Knative application
* [Internal (cluster-local) services](service-internal/)
* [Automatic scaling](autoscaling/)
* [Limit RAM/CPU resources or require GPU](service-config/)
* Operations (Day 2)
* [Traffic splitting, blue/green updates](traffic-splitting/)
* Eventing
* [Processing IoT core events](eventing-iot/)
* [Twitter processing pipelines](eventing-pipeline/)
## Monitoring
> Note, the monitoring/observability components require [additional install](https://github.com/knative/docs/blob/master/serving/installing-logging-metrics-traces.md)
Run the following command to watch your Kubernetes pods while running the demos:
```shell
kubectl port-forward -n knative-monitoring \
$(kubectl get pods -n knative-monitoring --selector=app=grafana \
--output=jsonpath="{.items..metadata.name}") 3000
```
## Tracing
To enable event tracing first edit the tracing config
```shell
kubectl edit cm config-tracing -n knative-eventing
```
In this case I'm using Stackdriver so just add the following two lines. You can also use `zipkin` in which case you will also have to define the back-end. See the config map's comments for details.
```yaml
backend: stackdriver
sample-rate: "1.0"
```
> If you're tracing high volume events you may want to adjust the `sample-rate` to something smaller like `0.1` (10% of all events).
To view traces, navigate to the [Trace UI](https://console.cloud.google.com/traces/traces) in GCP console
