1. 备份

curl \
  -X POST 'http://172.17.0.1:37700/dumps'

返回结果如下：

{
  "taskUid": 57978,
  "indexUid": null,
  "status": "enqueued",
  "type": "dumpCreation",
  "enqueuedAt": "2022-06-21T16:10:29.217688Z"
}

可以根据返沪结果查看备份任务执行的状态

curl \
  -X GET 'http://localhost:37700/tasks/57978'

1.2. 把原数据移动到备份目录

mv data/data.ms back/

2. 恢复数据

2.1 启动新版本的 meilisearch

使用如下 docker-compose 配置启动新版本的服务

version: '3'
services:
  meilisearch_server:
    #image: docker.io/getmeili/meilisearch:v0.29
    image: getmeili/meilisearch:v1.0
    container_name: meilisearch_server
    entrypoint: /bin/sh
    command:
      - "-c"
      - "sleep 10000000"
    ports:
      - "37700:7700"
    volumes:
      - ./data:/meili_data
    #  - /home/data/docker/webcrawler_358_1636118043/webcrawler/apps.weixinqqq.com/pics:/usr/share/nginx/html/000-pics
    user: root
    network_mode: bridge
    environment:
      - MEILI_ENV=development

2.2 进入容器内部

docker-compose exec -it meilisearch_server sh

2.3 导入数据

# replace {dump_uid.dump} with the name of your dump file
./meilisearch --import-dump dumps/20230315-105044020.dump

等待数据导入完成。数据导入完成后，最后一行日志如下：

A batch of tasks was successfully completed

使用命令 Ctrl + C 退出 meilisearch。

3. 重启新版本 meilisearch

退出容器，修改 docker-compose 如下

version: '3'
services:
  meilisearch_server:
    #image: docker.io/getmeili/meilisearch:v0.29
    image: getmeili/meilisearch:v1.0
    container_name: meilisearch_server
    #entrypoint: /bin/sh
    #command:
    #  - "-c"
    #  - "sleep 10000000"
    ports:
      - "37700:7700"
    volumes:
      - ./data:/meili_data
    #  - /home/data/docker/webcrawler_358_1636118043/webcrawler/apps.weixinqqq.com/pics:/usr/share/nginx/html/000-pics
    user: root
    network_mode: bridge
    environment:
      - MEILI_ENV=development

然后重启容器，服务生效。
