General

For further information about keycloak, see the documentation.

Setup

Following, the two ways to setup keycloak are discussed. To be able to automate the process, a bash script was written.

The bash script follows the steps of the manual setup.

Manual

Keycloak comes with the so-called 'master' realm by default, which governs all other realms ('sub-realms'). It is for administrative purposes.

To allow 'normal' users to authenticate, a new realm should be created (for any given application / as needed) to separate concerns.

If an admin needs access to sub-realms, he should authenticate against the master realm, receive a token, and can then proceed to access the sub-realms.


For further information about keycloak, see the documentation.

Setup

Start docker container

  1. Do a   docker Do a `docker pull quay.io/keycloak/keycloak:11.0.3`3
  2. Start the docker container with set env vars for 'KEYCLOAK_USER' and 'KEYCLOAK_PASSWORD` on a preferred port. Internal port is 8080.
  3. Navigate to http://localhost:8080/auth/admin and login, getting access to the master realm / admin console.
  4. Create an 'onap' realm

Following, three steps need to be done. The creation of the default users, creating and assigning roles, and the creation of a client for onap/odlux to use for authentication of the users.

...

  1. Navigate to 'Clients' and create a new one
  2. Create a client with client ID 'odlux.app' and client protocol 'openid-connect'
  3. Select client and open 'Settings' tab
  4. enable if not already done
    1. Direct Access Grants
    2. Standard Flow Enabled
  5. Add valid redirect urls for your onap installation
  6. Set access type to 'confidential'
  7. Add valid redirect urls for your onap installation(Save. Navigate to the 'credentials' tab and create your secret)
  8. (Note: If the lifespan of a token should be longer, it can be updated under the 'Advanced Settings' dropdown)

Automated

To automate the process, the following script can be used. Make sure to download the realm.json file. Place both files next to each other,

The bash script will pull the correct docker container, start it with admin/username set to 'admin', import the 'onap' realm and 'odlux.app' client, create default users in accordance with User management, and set their roles.

Known problems - change secret of client / automated creation

Further setup

Before you go and run Keycloak in production there are a few more things that you will want to do, including:

  • Switch to a production ready database such as PostgreSQL

  • Configure SSL with your own certificates

  • Switch the admin password to a more secure password

Quoted from: [https://www.keycloak.org/getting-started/getting-started-docker]

To access the secret via the GUI, the access-type must be changed to 'confidential' and saved. Following, the 'credentials' tab gets visible in the GUI.

On the credentials tab, the current secret can be copied or a new one created.

Currently, the client can not be created as confidential via the REST API.
