QuarkusCoffeeshop Install

NOTE: Ansible must be installed https://docs.ansible.com/ansible/latest/installation_guide/index.html

The QuarkusCoffeeshop Ansbile Role performs a basic installation that includes the microservices for a coffeeshop, installation of the Crunchy PostgreSQL DB, AMQ Streams (Kafka.)

The QuarkusCoffeeshop Role will deploy an event-driven demo application built with Quarkus, AMQ Streams (Kafka), and MongoDB. The application deploys to OpenShift (Kubernetes.) The source code for the quarkuscoffeeshop application support doc can be found here.

Requirements

• OpenShift 4.12 an up Cluster installed
• Docker or podman

Currently tested on

• OpenShift 4.12.2
• OpenShift Pipelines: 1.9.0
• AMQ Streams: 2.3.0-0odm
• Postgres Operator: v5.3.0
• OpenShift Quay: v3.8.1
• OpenShift GitOps: v1.7.1

Quick Start

Set Environment variables for standard deployment

This command will deploy the application on a Single cluster with the following services below.

• AMQ Streams
• Postgres Operator configuration
• quarkus coffeeshop helm deployment

$ cat >source.env<<EOF
CLUSTER_DOMAIN_NAME=clustername.example.com
TOKEN=sha256~XXXXXXXXXXXX
ACM_WORKLOADS=n
AMQ_STREAMS=y
CONFIGURE_POSTGRES=y
MONGODB_OPERATOR=n
MONGODB=n
HELM_DEPLOYMENT=y
DELETE_DEPLOYMENT=false
DEBUG=-v
EOF
$ podman run  -it --env-file=./source.env  quay.io/quarkuscoffeeshop/quarkuscoffeeshop-ansible:v4.12.1

Set Environment variables for ACM WORKLOADS

• Gogs server
• OpenShift Pipelines
• OpenShift GitOps
• Quay.io
• AMQ Streams
• Postgres Template deployment
• homeoffice Tekton pipelines
• quarkus-coffeeshop Tekton pipelines

$ cat >source.env<<EOF
CLUSTER_DOMAIN_NAME=clustername.example.com
TOKEN=sha256~XXXXXXXXXXXX
ACM_WORKLOADS=y
AMQ_STREAMS=y
CONFIGURE_POSTGRES=y

DELETE_DEPLOYMENT=false
DEBUG=-v
EOF
$ podman run  -it --env-file=./source.env  quay.io/quarkuscoffeeshop/quarkuscoffeeshop-ansible:v4.12.1

Optional: Change namespace for helm deployments
default is quarkuscoffeeshop-demo

$ cat >source.env<<EOF
CLUSTER_DOMAIN_NAME=clustername.example.com
TOKEN=sha256~XXXXXXXXXXXX
ACM_WORKLOADS=n

Usage

• Default web page 5.0.1-SNAPSHOT
  • http://quarkuscoffeeshop-web-quarkus-cafe-demo.apps.example.com/ this endpoint is used to view the events coming into the cluster
• Default web page v3.3.1
  • http://quarkuscoffeeshop-web-quarkus-cafe-demo.apps.example.com/cafe this endpoint is used to view the events coming into the cluster
• If you deploy skip_quarkus_cafe_customermock this will automatically push events to the quarkus cafe dashboard.
• If you would like to manally push events to AMQ use the command below.

export ENDPOINT="quarkuscoffeeshop-web-quarkus-cafe-demo.apps.ocp4.example.com"
curl  --request POST http://${ENDPOINT}/order \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
-d '{
    "beverages": [
        {
            "item": "COFFEE_WITH_ROOM",
            "name": "Mickey"
        },
        {
            "item": "CAPPUCCINO",
            "name": "Minnie"
        }
    ],
    "kitchenOrders": [
        {
            "item": "CAKEPOP",
            "name": "Mickey"
        },
        {
            "item": "CROISSANT",
            "name": "Minnie"
        }
    ]
}'

Developer Notes

• OpenShift 4.10 an up Cluster installed
• Ansible should be installed on machine
• oc cli must be installed
• Ansible community.kubernetes module must be installed ansible-galaxy collection install community.kubernetes
• Install Helm Binary
• Postges Operator for Quarkus CoffeeShop 5.0.1-SNAPSHOT Deployments

Role Variables

Download the deploy-quarkuscoffeeshop-ansible.sh shell script

$ curl -OL https://raw.githubusercontent.com/quarkuscoffeeshop/quarkuscoffeeshop-ansible/master/files/deploy-quarkuscoffeeshop-ansible.sh
$ chmod +x deploy-quarkuscoffeeshop-ansible.sh
$ ./deploy-quarkuscoffeeshop-ansible.sh -d ocp4.example.com -t sha-123456789 -p 123456789 -s ATLANTA

To Build container image

podman build -t  quarkuscoffeeshop-ansible:v0.0.2 -f Dockerfile

Test Container

podman run  -it   --env-file=./source.env  quarkuscoffeeshop-ansible:v0.0.2 bash or
podman run  -it --env-file=./source.env   localhost/quarkuscoffeeshop-ansible:v0.0.2

Delete old containers

podman rm $(podman ps -a | grep Exited | awk '{print $1}')
podman rmi localhost/quarkuscoffeeshop-ansible:v0.0.2 

Troubleshooting

Force delete kafka crds after bad install

oc get crds -o name | grep '.*\.strimzi\.io' | xargs -r -n 1 oc delete
