Keycloak 导入多个领域文件 import multiple realms

官方文档 https://www.keycloak.org/docs/7.0/server_admin/#admin-console-export-import

If more than one realm file needs to be imported, a comma separated list of file names can be specified.

This is more appropriate than the cases before, as this will happen only after the master realm has been initialized.

Examples:

• -Dkeycloak.import=/tmp/realm1.json

• -Dkeycloak.import=/tmp/realm1.json,/tmp/realm2.json

使用场景：

在上线前需要在本地新建出不同的realm，然后导出成json配置文件，集成到docker-compose配置文件里，这样发布的时候就可以比较方便，直接部署完就自动新建出不同的realm。

（0） 启动： docker run -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=admin  -p 8080:8080 jboss/keycloak

登录localhost:8080, 先配置realm，新建完导出realm。这里可以新建多个realm，分别导出多个json文件。

（1）把刚才启动的docker停止，可以直接删除上一步用到的container 也可以先留着：

删除的命令是 docker rm <container ID>

（2）新建docker-compose.yml，内容如下， 然后执行启动命令：docker-compose up -d

version: "3"
services:
  keycloak:
    image: jboss/keycloak:7.0.0
    ports:
      - "8080:8080"
    volumes:
      - "./imports:/Users/luciawang/workspace/practise/docker-compose/imports/"
    environment:
      - "KEYCLOAK_USER=admin"
      - "KEYCLOAK_PASSWORD=admin"
      - "DB_VENDOR=postgres"
      - "DB_ADDR=postgres"
      - "DB_DATABASE=postgres"
      - "DB_USER=postgres"
      - "DB_PASSWORD=123456"
      - "PROXY_ADDRESS_FORWARDING=true"
      - "KEYCLOAK_IMPORT=/Users/luciawang/workspace/practise/docker-compose/imports/realms.json,/Users/luciawang/workspace/practise/docker-compose/imports/realms1.json" 
    depends_on:
      - postgres
  postgres:
    image: postgres
    ports:
      - "5432:5432"
    environment:
      - "POSTGRES_PASSWORD:123456"

另一种方式：

version: "3"
services:
  keycloak:
    image: jboss/keycloak:7.0.0
    ports:
      - "8080:8080"
    volumes:
      - "./imports:/Users/lucia/workspace/practise/docker-compose/imports/"
    environment:
      - "KEYCLOAK_USER=admin"
      - "KEYCLOAK_PASSWORD=admin"
      - "DB_VENDOR=postgres"
      - "DB_ADDR=postgres"
      - "DB_DATABASE=postgres"
      - "DB_USER=postgres"
      - "DB_PASSWORD=123456"
      - "PROXY_ADDRESS_FORWARDING=true"
    command:
      - "-b 0.0.0.0 -Dkeycloak.import=/Users/lucia/workspace/practise/docker-compose/imports/realms.json,/Users/luciawang/workspace/practise/docker-compose/imports/realms1.json"
    depends_on:
      - postgres
  postgres:
    image: postgres
    ports:
      - "5432:5432"
    environment:
      - "POSTGRES_PASSWORD:123456"

登录localhost:8080, 进入的用户名密码都是admin，查看一下是否所有的realm都新建成功了
