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
