Quarkus App for Polls
=============================
### Launch on OpenShift
Images are downloaded from docker hub
Images:
- Postgres (image debezium/postgres) on port 5432
- AMQ Streams (Zookeeper on port 2181 and Kafka on port 9092)
- Voting Service on port 8080
In order to create the demo on your openshift environment, you need:
- ocp user with cluster-admin role
- oc client installed on your machine
- AMQ Streams 1.x for ocp downloaded from Red Hat
https://access.redhat.com/jbossnetwork/restricted/listSoftware.html?downloadType=distributions&product=jboss.amq.streams
Follow these instructions to create the demo:
Login to ocp, create a new project, create e new service account runasanyuid (postgres must run as root):
```bash
oc login --token=
oc new-project quarkus-voting
oc create serviceaccount runasanyuid
oc adm policy add-scc-to-user anyuid -z runasanyuid -n quarkus-voting
```
Create postgres, then create voting database:
```bash
oc new-app debezium/postgres
oc patch dc/postgres --patch '{"spec":{"template":{"spec":{"serviceAccountName": "runasanyuid"}}}}'
oc exec $(oc get pods | grep postgres | cut -d " " -f1) -- bash -c 'psql -h localhost -p 5432 -U postgres -c "CREATE DATABASE voting;"'
```
#### Install AMQ Streams on OpenShift 3.11
Install AMQ Streams cluster operator and a kafka cluster with 3 brokers (ephemeral and with prometheus metrics).
This step requires that you've downloaded and unpacked the AMQ Streams zip archive for ocp
(for more info about the installation, https://access.redhat.com/documentation/en-us/red_hat_amq/7.2/html-single/using_amq_streams_on_openshift_container_platform/index)
```bash
#replace the template namespace with quarkus-voting
sed -i 's/namespace: .*/namespace: quarkus-voting/' install/cluster-operator/*RoleBinding*.yaml
oc apply -f install/cluster-operator/020-RoleBinding-strimzi-cluster-operator.yaml -n quarkus-voting
oc apply -f install/cluster-operator/031-RoleBinding-strimzi-cluster-operator-entity-operator-delegation.yaml -n quarkus-voting
oc apply -f install/cluster-operator/032-RoleBinding-strimzi-cluster-operator-topic-operator-delegation.yaml -n quarkus-voting
oc apply -f install/cluster-operator -n quarkus-voting
oc apply -f examples/metrics/kafka-metrics.yaml
```
#### Install AMQ Streams on OpenShift 4.x
a) In the OpenShift 4 web console, click Operators > OperatorHub.
b) Search or browse for the AMQ Streams Operator, in the Streaming & Messaging category.
c) Click the AMQ Streams tile and then, in the sidebar on the right, click Install.
d) On the Create Operator Subscription screen, choose from the following installation and update options:
Installation Mode: Choose to install the AMQ Streams Operator to a specific (project) namespace
e) Click Subscribe; the AMQ Streams Operator is installed to your OpenShift cluster.
Verify that the amq-streams-cluster-operator is Running:
```bash
oc get pods
NAME READY STATUS RESTARTS AGE
amq-streams-cluster-operator-v1.4.0-55f4b48cc6-mhckl 1/1 Running 0 56s
```
Then apply the kafka CRD:
```bash
oc apply -f examples/metrics/kafka-metrics.yaml
```
#### Install voting microservice
```bash
cd voting/
./mvnw clean package -Dquarkus.container-image.build=true -Dquarkus.kubernetes.deploy=true
```
#### Install prometheus and grafana
```bash
wget https://raw.githubusercontent.com/strimzi/strimzi-kafka-operator/0.10.0/metrics/examples/prometheus/kubernetes.yaml
mv kubernetes.yaml prometheus.yaml
oc apply -f prometheus.yaml -n quarkus-voting
oc adm policy add-cluster-role-to-user prometheus -z prometheus-server
wget https://raw.githubusercontent.com/strimzi/strimzi-kafka-operator/0.10.0/metrics/examples/grafana/kubernetes.yaml
mv kubernetes.yaml grafana.yaml
oc apply -f grafana.yaml -n quarkus-voting
oc expose svc/grafana
```
Download and import grafana dashboard for kafka and zookeeper, dashboard can be downloaded at:
wget https://raw.githubusercontent.com/strimzi/strimzi-kafka-operator/master/metrics/examples/grafana/strimzi-kafka.json
wget https://raw.githubusercontent.com/strimzi/strimzi-kafka-operator/master/metrics/examples/grafana/strimzi-zookeeper.json
Follow the instruction to import the kafka and zookeeper grafana dashboards:
https://strimzi.io/docs/latest/#grafana_dashboard
Import the custom grafana dashboard for showing poll results:
```bash
grafana/grafana-unconference.json
```
Results will be available at:
```bash
http:///poll/results
```
and on a grafana dashboard
### Launch on local env - linux and mac
Launch the bootstrap script to create the docker containers.
Images are downloaded from docker hub.
Images:
- Postgres (image debezium/postgres) on local port 5432
- Zookeeper (image debezium/zookeeper) on local port 2181
- Kafka (image debezium/kafka) on local port 9092
- Jaeger (image jaegertracing/all-in-one) on local port 16686
If you want to run the voting application in dev mode use the script:
```bash
./scripts/deploy-docker-no-voting.sh
```
and then run the voting application with:
```bash
cd voting/
./mvnw clean compile quarkus:dev (debug port 5005)
```
To test the application run:
```bash
cd voting/
mvn clean compile test
```
### Endpoints
Test them with swagger, available at:
```bash
http:///swagger-ui
http:///openapi
```
### Jaeger
See tracing at:
```bash
http://:16686
```
### Compile and Create Images
Launch the script to compile and create the native images:
```bash
./scripts/build-native-image.sh
```
