Alfresco Identity Service

⚠ WARNING: Alfresco Identity Service has reached End of Life. Please refrain from using Alfresco Identity Service at this time and switch to raw Keycloak instead. This branch now contains a set of tests and examples for vanilla Keycloak, whereas the, now unmaintained, Alfresco Identity Service development branch has been moved to release/2.0.x.

Keycloak is a central component responsible for identity-related capabilities needed by other Alfresco software, such as managing users, groups, roles, profiles, and authentication. Currently it deals just with authentication. This project contains the open-source core of this service.

For installing Keycloak you can choose either a sample Kubernetes distribution or a sample standalone distribution. Both methods are described in the following sections. For upgrading, it is recommended to follow the official Keycloak upgrading guide.

Check the Kubernetes deployment prerequisites and standalone prerequisites before you start.

Any variation from these technologies and versions may affect the end result. If you do experience any issues please let us know through our Gitter channel.

Standalone Distribution

Overview

This guide helps you get started with Keycloak. It covers simple standalone startup with the Alfresco example realm, Alfresco Theme and use of the default database. Advanced deployment options are not covered. For a deeper description of Keycloak features or configuration options, consult the official Keycloak readme .

Prerequisites

1. Java 11 JDK

Installing and booting

1. Move to distribution and execute the following command: make.

2. Wait for the build process to complete, then locate the .distribution/alfresco-keycloak-${KEYCLOAK_VERSION} directory and cd into it.

3. Run the standalone boot script.

Linux/Unix

$ cd bin
$ ./kc.sh start --import-realm --http-relative-path="/auth" --hostname=<HOSTNAME> --https-certificate-file=<PATH_TO_CERT_FILE> --https-certificate-key-file=<PATH_TO_CERT_KEY_FILE>

Windows bat

> cd bin
> kc.bat start --import-realm --http-relative-path=/auth --hostname=<HOSTNAME> --https-certificate-file=<PATH_TO_CERT_FILE> --https-certificate-key-file=<PATH_TO_CERT_KEY_FILE>

This is deployed with the default example realm applied which results in default values of:

Property	Value
Admin User Username	admin
Admin User Password	admin
Admin User Email	[email protected]
Alfresco Client Redirect URIs	*

Creating the Master Realm Admin Account

After the server boots, open http://<IP_ADDRESS>:8080/auth in your web browser. The welcome page will indicate that the server is running.

Enter a username and password to create an initial admin user.

This account will be permitted to log in to the master realm’s administration console, from which you will create realms and users and register applications to be secured by Keycloak.

The Alfresco realm already has the admin account created and you can reach the realm console with the following url:

http://<IP_ADDRESS>:8080/auth/admin/alfresco/console/

Modifying the valid redirect URIs

Note: for security reasons, the redirect URIs should be as specific as possible. See Keycloak official documentation.

1. After logging in to the Alfresco realm follow the left side menu and choose clients.
2. Choose the Alfresco client from the client list.
3. In the client settings window you will have to fill in your appropriate redirect URI's for the Content and Process applications.

Kubernetes Deployment

Kubernetes Cluster

These instructions illustrate deployment to a Kubernetes cluster on EKS.

Please check the ACS deployment documentation.

If you are deploying Keycloak into a cluster with other Alfresco components such as Content Services and Process Services, a VPC and cluster with 5 nodes is recommended. Each node should be a m4.xlarge EC2 instance.

K8s Cluster Namespace

Create the namespace if it does not already exist, to avoid conflicts in the cluster:

export DESIREDNAMESPACE=example
kubectl create namespace $DESIREDNAMESPACE

This environment variable will be used in the deployment steps.

Deploying the sample Keycloak Chart

1. Prepare the EKS cluster by deploying an ingress. See the instruction here.

2. cd to the root of this repository.

3. Get the release name from the ingress deployment (step 1) and set it as a variable:

export INGRESS_RELEASENAME=<YOUR_INGRESS_RELEASE_NAME>

4. Set the Keycloak release name as a variable:

export RELEASENAME=kc

5. Deploy Keycloak.

helm install $RELEASENAME helm/alfresco-keycloak --devel \
  --namespace $DESIREDNAMESPACE

6. Wait for the release to get deployed (When checking status your pods should be READY 1/1):

helm status $RELEASENAME

7. Get local or ELB IP and set it as a variable for future use:

export ELBADDRESS=$(kubectl get services $INGRESS_RELEASENAME-ingress-nginx-controller --namespace=$DESIREDNAMESPACE -o jsonpath='{.status.loadBalancer.ingress[0].hostname}')

The above steps will deploy Keycloak with the default example realm applied which results in default values of:

Property	Value
Admin User Username	admin
Admin User Password	admin
Admin User Email	[email protected]
Alfresco Client Redirect URIs	http://localhost*

(Note that APS expects the email as the username)

Changing Alfresco Client redirectUris

Note: for security reasons, the redirect URIs should be as specific as possible. See Keycloak official documentation.

You can override the default redirectUri of http://localhost* for your environment with the realm.alfresco.client.redirectUris property:

helm install $RELEASENAME helm/alfresco-keycloak --devel \
  --set realm.alfresco.client.redirectUris="{$DNSNAME}" \
  --namespace $DESIREDNAMESPACE

including multiple redirectUris:

helm install $RELEASENAME helm/alfresco-keycloak --devel \
  --set realm.alfresco.client.redirectUris="{$DNSNAME,$DNSNAME1,$DNSNAME2}" \
  --namespace $DESIREDNAMESPACE

Note in case of multiple redirectUris the values must be comma-separated with no whitespaces surrounding the corresponding commas.

If you want to deploy your own realm with further customizations, see Customizing the Realm below.

Changing Alfresco Client webOrigins

Similarly to redirectUris, webOrigins can be changed by overriding the realm.alfresco.client.webOrigins property:

helm install $RELEASENAME helm/alfresco-keycloak --devel \
  --set realm.alfresco.client.webOrigins="{$DNSNAME}" \
  --namespace $DESIREDNAMESPACE

For multiple webOrigins:

helm install $RELEASENAME helm/alfresco-keycloak --devel \
  --set realm.alfresco.client.webOrigins="{$DNSNAME,$DNSNAME1,$DNSNAME2}" \
  --namespace $DESIREDNAMESPACE

Multiple Replicas, High Availability and Clustering

For added resilience, we rely on support in the Keycloak chart for specifying multiple replicas. To enable this you will need to deploy the Keycloak chart with this additional setting:

  --set keycloakx.replicas=3

In addition, for high availability, Keycloak supports clustering. For more information on how to configure high availability and clustering, you can consult this additional documentation.

Keycloak-X chart Readme

Configuring Keycloak for production

NOTE: Be aware that Keycloak recommends that sticky sessions are used so keep that in mind if you choose to use a different ingress type than nginx.

Customizing the Realm

Customizing the Realm During Deployment

1. You will need a realm file. A sample realm file is provided.

2. Create a secret using your realm json file

!!NOTE The secret name must be realm-secret, and the realm file name must not be alfresco-realm.json.

kubectl create secret generic realm-secret \
  --from-file=./realm.json \
  --namespace=$DESIREDNAMESPACE

3. Create a yaml file with following settings. The file name can be anything, for example: custom-values.yaml

keycloakx:
  extraEnv: |
    - name: KEYCLOAK_ADMIN
      value: admin
    - name: KEYCLOAK_ADMIN_PASSWORD
      value: admin
    - name: KEYCLOAK_IMPORT
      value: /data/import/alfresco-realm.json
    - name: JAVA_OPTS_APPEND
      value: >-
        -Djgroups.dns.query={{ include "keycloak.fullname" . }}-headless

NOTE: The above settings use the default admin/admin for keycloak username and password, you can replace those with your own values.

4. Deploy the Keycloak chart with the new settings:

helm install $RELEASENAME helm/alfresco-keycloak --devel \
  -f custom-values.yaml \
  --namespace $DESIREDNAMESPACE

For further details see Setting a Custom Realm.

Once Keycloak is up and running, login to the Management Console to configure the required realm.

Manually

1. Add a realm named "Alfresco"

2. Create an OIDC client named "alfresco" within the Alfresco realm

3. Create a group named "admin"

4. Add a new user with a username of "testuser", email of "[email protected]" and first and last name of "test"

Using the Sample Realm File

1. Go to the Add Realm page and click the "Select File" button next to the Import label.

2. Choose the sample realm file and click the "Create" button.
