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
