项目结构

自定义SPI注册

docker cp keycloak-service-self-spi.jar keycloak:/opt/
docker cp module-one-add.cli keycloak:/opt/
docker exec -it keycloak bash
$JBOSS_HOME/bin/jboss-cli.sh --file=/opt/module-one-add.cli

使用docker commit保存你当前容器为一个新的镜像，然后启动它即可

Dockerfile

FROM jboss/keycloak:11.0.3
USER root
#self provider
WORKDIR /opt
COPY target/keycloak-service-self-spi.jar .
RUN mkdir cli
COPY module-one-add.cli cli/
RUN $JBOSS_HOME/bin/jboss-cli.sh --file=cli/module-one-add.cli
RUN rm -rf $JBOSS_HOME/standalone/configuration/standalone_xml_history/current

打包

docker build -t self/keycloak .

后续的扩展

当有了自己的SPI接口之后，它也有了对应的ProviderFactory和Provider，然后你就可以在扩展它了，一般的步骤是：

1. 建立新项目

2. 依赖上面的SPI项目（它已经被注入到keycloak里，就像keycloak系统的spi）

3. 将新的项目打包上传到/opt/jboss/keycloak/standalone/deployments目录完成自动化部署

4. 在resources/META-INF/jboss-deployment-structure.xml里添加上面项目spi module

5. 注册成功之后，在keycloak管理平台的server-info/providers里会有体现
