Deploying the app on Openshift

  • Login into the cluster using oc login.

  • Create a new project.

oc new-project sf-quarkus
  • Clone the customer-ms-quarkus repo.
git clone https://github.com/ibm-garage-ref-storefront/customer-ms-quarkus.git
cd customer-ms-quarkus
  • Setup the database.
cd database_setup
./setup_database.sh sf-quarkus
cd ..
  • Include the OpenShift extension like this:
./mvnw quarkus:add-extension -Dextensions="openshift"

This will add the below dependency to your pom.xml

<dependency>
  <groupId>io.quarkus</groupId>
  <artifactId>quarkus-openshift</artifactId>
</dependency>
  • Now, navigate to src/main/resources/application.properties and add the below.
# Create ibm-java-env secret with corresponding keycloak credentials

quarkus.openshift.env.mapping.keycloak-client-id.from-secret=ibm-java-env
quarkus.openshift.env.mapping.keycloak-client-id.with-key=KEYCLOAK_CLIENT_ID
quarkus.openshift.env.mapping.keycloak-client-secret.from-secret=ibm-java-env
quarkus.openshift.env.mapping.keycloak-client-secret.with-key=KEYCLOAK_CLIENT_SECRET

quarkus.openshift.env.vars.couchdb-host=customer-couchdb-svc-couchdb
quarkus.openshift.env.vars.couchdb-port=5985
quarkus.openshift.env.vars.couchdb-user=user
quarkus.openshift.env.vars.couchdb-password=passw0rd

quarkus.oidc.auth-server-url=https://keycloak-keycloak.mq-devops-6ccd7f378ae819553d37d5f2ee142bd6-0000.par01.containers.appdomain.cloud/auth/realms/sfrealm
  • To trigger a build and deployment in a single step, run the below command.
./mvnw clean package -Dquarkus.kubernetes.deploy=true

If it is run successfully, you will see something like this.

  • Now create the route as follows.
oc expose svc customer-ms-quarkus
  • Grab the route.
oc get route customer-ms-quarkus --template='{{.spec.host}}'

You will see something like below.

$ oc get route customer-ms-quarkus --template='{{.spec.host}}'
customer-ms-quarkus-sf-quarkus-dev.mq-devops-6ccd7f378ae819553d37d5f2ee142bd6-0000.par01.containers.appdomain.cloud
  • Now access the endpoint using http://<route_url>/health.

For instance if using the above route, it will be https://customer-ms-quarkus-sf-quarkus-dev.mq-devops-6ccd7f378ae819553d37d5f2ee142bd6-0000.par01.containers.appdomain.cloud/health.
