keycloak - 开发环境的配置持久化

前情提要： Keycloak - docker 运行 & 前端集成

本来是想顺便试一下 Okta 集成的，但是发现 Okta 没有本地的 docker 镜像，他们毕竟是做 Identity as a service……算了……

更新后的 docker compose 如下：

version: "3.8"
services:
  keycloak:
    container_name: keycloak
    image: quay.io/keycloak/keycloak:21.1.1
    command: start-dev --import-realm
    volumes:
      - ./realm-config/export:/opt/keycloak/data/import
    environment:
      - KEYCLOAK_ADMIN=admin
      - KEYCLOAK_ADMIN_PASSWORD=pass
      - DB_VENDOR=h2
    ports:
      - 9090:8080

主要的区别就是添加了一些指令、镜像源换成官方镜像，随后更新了一下 volume 和环境名，其他和前文基本都一样

持久过程

其实主要就是跑两个 docker 指令，一个是执行 /opt/keycloak/bin/kc.sh 的脚本去导出当前有的配置，另一个就是使用 docker cp 将 docker 中的配置保存到本地：

❯ docker exec -it keycloak /opt/keycloak/bin/kc.sh export --dir /opt/keycloak/data/export
