Authentication and Authorization

This part of the project demonstrates how to do authentication and authorization in Quarkus applications and web applications. Keycloak is used as OpenID Connect provider.

Documentation

There are blog entries and a workshop that describe how this project has been implemented:

The workshop linked above is a description on how to use the code.

Scenario

In order to demonstrate the security features, a sample application is used which displays links to articles in a web application only when a user is logged in and has the role 'user'.

The web application invokes the web-api service and then invokes the articles service. The web-api service also provides an endpoint to read the current user name.

This diagram shows the architecture:

This is a gif of the web application:

Setup

At this point the code is run locally which means you need a JVM and Maven. For the web application you also need yarn. In this setup, Keycloak is installed on a Red Hat OpenShift cluster on IBM Cloud.

Step 0: Clone the Repo

$ git clone https://github.com/IBM/cloud-native-starter.git
$ cd security

Step 1: Create an OpenShift cluster, e.g. on the IBM Cloud

https://cloud.ibm.com/kubernetes/catalog/create?platformType=openshift

Step 2: Login in a Terminal

Get the login command from the OpenShift Web Console, e.g.

$ oc login --token=OnMwHZ4FLgZnWdcxxxxxxxxxxxxxxx --server=https://c107-e.us-south.containers.cloud.ibm.com:30058

Step 3: Install the Keycloak Operator

Follow these steps to install the operator via the OpenShift Web Console: documentation.

Alternatively you can install it programmatically:

$ oc new-project keycloak
$ oc create -f keycloak-operator.yaml

Step 4: Create a Keycloak Cluster

You can create the Keycloak cluster either in the OpenShift Web Console or programmatically:

$ oc create -f keycloak.yaml
$ oc get keycloak/example-keycloak -o jsonpath='{.status.ready}'

Step 5: Get the admin password and Keycloak URLs

  • Get admin password:
$ oc get secret credential-example-keycloak -o go-template='{{range $k,$v := .data}}{{printf "%s: " $k}}{{if not $v}}{{$v}}{{else}}{{$v | base64decode}}{{end}}{{"\n"}}{{end}}'
  • Get Keycloak URLs:
$ KEYCLOAK_URL=https://$(oc get route keycloak --template='{{ .spec.host }}')/auth &&
echo "" &&
echo "Keycloak:                   $KEYCLOAK_URL" &&
echo "Keycloak Admin Console:     $KEYCLOAK_URL/admin" &&
echo "Keycloak Account Console:   $KEYCLOAK_URL/realms/myrealm/account" &&
echo "Keycloak [auth-server-url]: $KEYCLOAK_URL/realms/quarkus"

Step 6: Import Realm in Keycloak

Open the Keycloak console and log in as admin. Then import quarkus-realm.json. Check the setup Keycloak documentation for how to import the realm.

Step 7: Configure articles-secure

Insert your the auth-server-url URL of your Keycloak instance in application.properties. Therefore you use the Keycloak URL of the output in your terminal.

Keycloak [auth-server-url]: https://YOUR_URL/auth/realms/quarkus

Step 8: Configure web-api-secure

Insert your the auth-server-url URL you know from above in application.properties.

Step 9: Configure web-app

Now insert the Keycloak URL Keycloak URL/auth from the output of your terminal session in main.js.

  urls = {
    api: 'http://localhost:8081/',
    login: 'https://YOUR_URL/auth' // insert your http or https://<KeycloakURL>/auth
  }
}

Step 10: Run web-app

Run first terminal (on port 8080):

$ cd security/web-app
$ yarn install
$ yarn serve

Step 11: Run web-api

Run second terminal (on port 8081):

$ cd security/web-api-secure
$ mvn clean package quarkus:dev

Step 12: Run articles-secure

Run third terminal (on port 8082):

$ cd security/articles-secure
$ mvn clean package quarkus:dev

Step 13: Open Web App

http://localhost:8080
