| # Identus Keycloak Plugins | ||
|
|
||
|  | ||
|  | ||
|
|
||
| # Overview | ||
|
|
||
| This repository provides a Keycloak Plugin that extends Keycloak's functionality to handle Self-Sovereign Identity (SSI) tasks, | ||
| including OpenID for verifiable credential issuance. | ||
|
|
||
| # Getting started | ||
|
|
||
| ## Using published docker image | ||
|
|
||
| ### Default Keycloak plugin image | ||
|
|
||
| The plugin is available as a pre-bundled Docker image. | ||
| This image includes Keycloak and the plugin enabled for basic use cases. | ||
| For a more complex setup, the JAR file published in the Maven repository should be used to build a custom Keycloak image. | ||
| The docker-compose configuration below allows spinning up a basic Keycloak instance with the plugin enabled as part of the Identus cloud agent stack. | ||
|
|
||
| ```yaml | ||
| services: | ||
| keycloak-oid4vci-issuer: | ||
| image: ghcr.io/hyperledger/identus-keycloak-plugins:0.1.0 | ||
| ports: | ||
| - "9980:8080" | ||
| command: | ||
| - start-dev | ||
| - --features=preview | ||
| - --health-enabled=true | ||
| - --hostname-url=http://localhost:9980 | ||
| - --hostname-admin-url=http://localhost:9980 | ||
| environment: | ||
| IDENTUS_URL: <AGENT_URL> # point to cloud agent instance | ||
| KEYCLOAK_ADMIN: admin | ||
| KEYCLOAK_ADMIN_PASSWORD: admin | ||
| restart: always | ||
|
|
||
| # Identus cloud agent and other services below | ||
| ``` | ||
|
|
||
| ### Customized Keycloak plugin image | ||
|
|
||
| In many cases, Keycloak customization is necessary for branding or to meet custom | ||
| authentication and authorization requirements. The default plugin image can be used | ||
| in conjunction with docker multi-stage builds to extract the Keycloak plugin JARs and | ||
| create a customized Keycloak image. | ||
|
|
||
| The image contains plugin JARs in the `/opt/keycloak/providers` directory | ||
|
|
||
| Example `Dockerfile` | ||
|
|
||
| ``` | ||
| FROM ghcr.io/hyperledger/identus-keycloak-plugins:0.1.0 AS dist | ||
| FROM quay.io/keycloak/keycloak:23.0.7 | ||
| COPY --from=dist /opt/keycloak/providers/<PLUGIN_FILE>.jar /opt/keycloak/providers/<PLUGIN_FILE>.jar | ||
| # more steps to customize assets / themes / providers | ||
| RUN /opt/keycloak/bin/kc.sh build | ||
| ENTRYPOINT [ "/opt/keycloak/bin/kc.sh" ] | ||
| ``` | ||
|
|
||
| Please refer to the official [Keycloak documentation](https://www.keycloak.org/server/containers) | ||
| for customization using JAR providers. | ||
|
|
||
| ## Using published JAR | ||
|
|
||
| Each plugin is available individually on [Github maven packages](https://github.com/orgs/hyperledger/packages?repo_name=identus-keycloak-plugins), | ||
| for easy integration with your build process and fine-grained control over which plugins are included when customizing Keycloak. | ||
|
|
||
| Please refer to the official [Keycloak documentation](https://www.keycloak.org/server/containers) | ||
| for customization using JAR providers. | ||
|
|
||
| # Available Plugins | ||
|
|
||
| ## `identus-keycloak-oid4vci` | ||
|
|
||
| Extends Keycloak for integration with Hyperledger Identus Cloud Agent in [OID4VCI](https://openid.net/specs/openid-4-verifiable-credential-issuance-1_0.html) flow. | ||
| The Keycloak instance to use this is the Issuer Authorization Server where the plugin takes care of | ||
| the OpenID extension in the issuance flow. | ||
| The plugin supports the Authorization Endpoint and Token Endpoint according to the specification. | ||
| Additionally, the plugin communicates with the cloud agent during holder authorization to coordinate the issuance session. | ||
|
|
||
