elasticdump 迁移 elasticsearch 数据

elasticdump 迁移 elasticsearch 数据

elasticdump github地址
https://github.com/taskrabbit/elasticsearch-dump

折腾了一会nodejs耐心尽失，果断使用docker方式。

1、下载docker镜像

拉取镜像

docker pull taskrabbit/elasticsearch-dump

2、导出数据

如果将数据导出为文件形式，需要将宿主机目录挂载至容器上。

# 提前创建数据目录。mkdir /data

导出数据至json文件中，将宿主机/data目录挂载到容器/tmp目录上，--output指定文件导出至/tmp目录中。

docker run --net=host --rm -ti -v /data:/tmp taskrabbit/elasticsearch-dump \   --input=http://localhost:9200/info-ad \   --output=/tmp/info-ad-map.json \   --type=data# 导出日志Wed, 11 Dec 2019 09:45:35 GMT | starting dumpWed, 11 Dec 2019 09:45:35 GMT | got 16 objects from source elasticsearch (offset: 0)Wed, 11 Dec 2019 09:45:35 GMT | sent 16 objects to destination file, wrote 16Wed, 11 Dec 2019 09:45:35 GMT | got 0 objects from source elasticsearch (offset: 16)Wed, 11 Dec 2019 09:45:35 GMT | Total Writes: 16Wed, 11 Dec 2019 09:45:35 GMT | dump complete# 导出文件[root@localhost /data]# lltotal 20-rw-r--r--. 1 root root 18192 Dec 11 17:45 info-ad-map.json

3、导入数据

docker run --net=host --rm -ti -v /data:/tmp taskrabbit/elasticsearch-dump \   --input=/tmp/info-ad-map.json \   --output=http://localhost:9200/abcd# 导入日志Wed, 11 Dec 2019 09:47:43 GMT | starting dumpWed, 11 Dec 2019 09:47:43 GMT | got 16 objects from source file (offset: 0)Wed, 11 Dec 2019 09:47:44 GMT | sent 16 objects to destination elasticsearch, wrote 16Wed, 11 Dec 2019 09:47:44 GMT | got 0 objects from source file (offset: 16)Wed, 11 Dec 2019 09:47:44 GMT | Total Writes: 16Wed, 11 Dec 2019 09:47:44 GMT | dump complete

ps：在使用localhost:9200时需要使用--net=host将网络挂载到容器上
