* Grafana Operator v5

* OpenShift 4.13

=== Ansible requirements

* https://www.ansible.com/[Ansible 3]

- https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html#control-node-requirements[Ansible's requirement]

* https://pypi.org/project/kubernetes/[Python's Kubernetes module]

=== Parameters

[options="header"]

|=======================

| Parameter | Example Value                                      | Definition

| token     | sha256~vFanQbthlPKfsaldJT3bdLXIyEkd7ypO_XPygY1DNtQ | access token for a user with cluster-admin privileges

| server    | https://api.my-cluster.com:6443                    | OpenShift cluster API URL

|=======================

=== Running the installation

You will need an user with permission to create a project and install operators on cluster level.

Export the user's `token` and the `server` API address as environment variables, then run the following command under the `ansible` folder:

----

cd demos_camel_k/ansible/

ansible-playbook -e token=${token} -e server=${server} playbook.yml

----

== Running the example

First you need to prepare the environment by creating the database used by the application:

----

# make sure you're logged in the right cluster

oc login

oc new-app --name postgresqldb -e POSTGRESQL_USER=redhat -e POSTGRESQL_PASSWORD=redhat  -e POSTGRESQL_DATABASE=camelk quay.io/gcamposo/postgresql-camelk:latest -n demo-camelk-api

----

now you can create the integrations following the instructions:

----

cd demos_camel_k/camel_k

oc create cm camel-k-api --from-file=openapi.yml

kamel run API.java 

kamel run Client.java

----

== Running Kaoto version(yaml)

----

oc project demo-camelk-api

kamel run API.yaml --dependency=mvn:io.quarkus:quarkus-jdbc-postgresql --dependency=camel:jdbc --dependency=camel:jslt --trait=route.enabled=true --trait=logging.json=false --trait=prometheus.enabled=true --open-api=file:openapi.yml --build-property=quarkus.datasource.camel.db-kind=postgresql --resource=file:spec.json --property=file:db.properties 

----

== Testing the integration

----

export ROUTE=$(oc get route api -o jsonpath='{.spec.host}')

#List messages saved in the db

curl $ROUTE/v1/camelk

----
