STEPS TO INTEGRATE KEYCLOAK WITH SW360 NEW UI

Install Java 17

• Update the package index: sudo apt update
• Install OpenJDK 17: sudo apt install openjdk-17-jdk

Set JAVA_HOME

• Edit the ~/.bashrc file: vim ~/.bashrc
• Add the following line at the end of the file: export JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64
• Save and exit the editor.
• Update the environment variables: source ~/.bashrc
• Or you can set environment variable in /etc/environment file

Install postgresql:

• Install PostgreSQL 14 or higher.

sudo apt update && sudo apt upgrade -y
sudo apt install postgresql-14

Set Username and Password in PostgreSQL:

• Switch to the PostgreSQL user: sudo su postgres
• Access the PostgreSQL console: psql
• Execute the following SQL commands:

CREATE USER keycloak WITH ENCRYPTED PASSWORD 'password';
CREATE DATABASE keycloak;
GRANT ALL PRIVILEGES ON DATABASE keycloak TO keycloak;

Install Keycloak:

• Download Keycloak 26.0.5 from the official repository.
• Or download the tar file wget https://github.com/keycloak/keycloak/releases/download/26.0.5/keycloak-26.0.5.tar.gz
• Extract the downloaded file to the /opt folder, sudo tar -xvf myfiles.tar -C /opt
• Goto keycloak conf folder and uncomment the following from keycloak.conf file:

# Database

# The database vendor.
db=postgres

# The username of the database user.
db-username=keycloak

# The password of the database user.
db-password=password

# The full database JDBC URL. If not provided, a default URL is set based on the selected database vendor.
db-url=jdbc:postgresql://localhost/keycloak

• Set environment variables for Keycloak administration:

export KEYCLOAK_ADMIN=admin
export KEYCLOAK_ADMIN_PASSWORD=admin

Start Keycloak:

• Navigate to the Keycloak directory, cd /path/to/keycloak/bin
• Run the start command with the necessary parameters:

./kc.sh start --log="console,file" --hostname-strict-backchannel=false --http-enabled=true --http-port=8083 --https-port=8533 --hostname-strict=false --hostname-strict-https=false

• Run the start command with the necessary parameters(with debug mode):

sudo ./kc.sh start  --log="console,file" --hostname-strict-backchannel=false --http-enabled=true --http-port=8083 --https-port=8533 --hostname-strict=false --debug  --log-level=INFO,org.eclipse.sw360.keycloak.spi:debug,org.eclipse.sw360.keycloak.event.listener:debug

Build the Backend:

• Build the SW360 backend code using Maven, mvn clean install -DskipTests -Dbase.deploy.dir=/opt/apache-tomcat-11.x.x/ -Dlistener.deploy.dir=/opt/keycloak-26.x.x/providers -P deploy
• Start the Apache Tomcat server.

Keycloak Providers and Libraries:

Providers are used to read users from sw360 db and register users from keycloak to sw360 db.

• After building the backend with deploy profile, following files should be copied and available at /opt/keycloak-26.0.5/providers/:

commonIO-19.0.0.jar
datahandler-19.0.0.jar
httpcore5-5.2.5.jar
libthrift-0.20.0.jar
spring-security-crypto-6.3.3.jar
sw360-keycloak-event-listener.jar
sw360-keycloak-user-storage-provider.jar

Keycloak Admin Console:

• Login to Keycloak admin console.

  username: admin
  password: admin
  

• Create Realm and name it sw360.

• Get the JWT issuer and key set for realm and update the backend file at rest/resource-server/src/main/resources/application.yml and reinstall the backend with Tomcat restart

  • Select "OpenID Endpoint Configuration" from the "Realm Settings" and copy "jwks_uri". It will look something like http://localhost:8083/realms/sw360/protocol/openid-connect/certs
  • Update the issuer-uri and jwk-set-uri in the application.yml file with this copied jwks_uri.
  • Build and install the backend one more time.

• Create Client in Keycloak.

  • Follow the below steps for client creation:

    • Under General settings, enter Client ID which will be used in .env file(SW360 Frontend Repo) as well as in rest.

    • In Capability config enable Client authentication.

    • Goto Login settings and enter below fields:

    Home URL: http://localhost:3000
    Valid redirect URIs: http://localhost:3000/api/auth/callback/keycloak, https://oauth.pstmn.io/v1/callback
    Valid post logout redirect URIs: +
    Web origins: *
    

• Create Client Scopes.

  • Create READ scope by clicking on Create client scope button.

  • Similarly create WRITE scope.

• Add Scopes to our Client.

  • Goto Clients, then select your newly created client in Client lists page.
  • Goto Client scopes page, click on Add client scope and there you will see your READ and WRITE scopes that you need to add.
  • Select both scopes and then click on Add(default).

• Create Groups.

  • Goto Groups and create different groups that we are going to use in sw360.

  • Create 7 groups: ADMIN, CLEARING_ADMIN, CLEARING_EXPERT, ECC_ADMIN, SECURITY_ADMIN, SW360_ADMIN, USER.

• Create an Attribute.

  • Goto Realm settings then click on User profile page where we can create a new attribute.

  • Create a new attribute by the name Department and give the required permissions as shown in screenshot.

• Add Event Listner.

  • Goto Events page in Realm settings.
  • Click on event listners dropdown and select sw360-add-user-to-couchdb.

• Access to external Databases.

  • Goto User federation and select sw360-user-storage-jpa providers.

  • Give proper name and create the custom provider.

• Check Authentication Settings

  • Goto Authentication and apply the permissions in Required actions as shown in screenshot.

• Create Users

  • To create a new user one can goto Users section.

  • Also check whether user is created in couchdb or not.

  • Set password for the newly created user by selecting the user and going to the Credentials page.

Clone SW360 Frontend Repository

• Run the git clone command, git clone git@github.com:eclipse-sw360/sw360-frontend.git
• Create .env file inside the repository and add the following data:

NEXTAUTH_SECRET = 'secret'
NEXT_PUBLIC_SW360_API_URL = 'http://localhost:8080'
NEXTAUTH_URL='http://localhost:3000'
NEXT_PUBLIC_SW360_REST_CLIENT_ID='trusted-sw360-client'
NEXT_PUBLIC_SW360_REST_CLIENT_SECRET='sw360-secret'
NEXT_PUBLIC_ENABLE_SW360_OAUTH_PROVIDER='true'
#possible values are sw360basic, sw360oauth, keycloak
#NEXT_PUBLIC_SW360_AUTH_PROVIDER='keycloak'
SW360_KEYCLOAK_CLIENT_ID=
SW360_KEYCLOAK_CLIENT_SECRET=
AUTH_ISSUER=http://localhost:8083/realms/sw360

• Get SW360_KEYCLOAK_CLIENT_ID and SW360_KEYCLOAK_CLIENT_SECRET from Keycloak console
  • SW360_KEYCLOAK_CLIENT_ID will be present in your client's Settings page.
  • SW360_KEYCLOAK_CLIENT_SECRET will be present in your clients's Credentials page

Install NVM

• Installs NVM (Node Version Manager) curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.4/install.sh | bash
• Download and Install Node.js nvm install 20.5.1
• Verifies the right Node.js version is in the environment node -v # should print v20.5.1
• Verifies the right NPM version is in the environment npm -v # should print 10.2.4
• Installs next npm install next@latest react@latest react-dom@latest

Build the Frontend

npm run build
npm run start
/usr/bin/google-chrome-stable --disable-web-security --user-data-dir="/home/${USER}/cors" --allow-file-access-from-files

Token Creation for REST

• Type of authorization will be OAuth 2.0.
• Enter the below details while creating a new Bearer token:
