Elasticdump migrates elasticsearch data

Elasticdump github address

Https://github.com/taskrabbit/elasticsearch-dump

After tossing about for a while, nodejs lost all patience and decisively used the docker method.

1. Download docker image

Pull the image

Docker pull taskrabbit/elasticsearch-dump2, export data

If you export the data as a file, you need to mount the host directory to the container.

# create a data directory in advance. Mkdir / data

Export the data to the json file, mount the host / data directory to the container / tmp directory, and export the specified file-- output to the / tmp directory.

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# export log 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# export file [root@localhost / data] # lltotal 20 RW Murray 1 root root 18192 Dec 11 17:45 info-ad-map.json3, import data docker run-- net=host-- rm-ti-v / data:/tmp taskrabbit/elasticsearch-dump\-- input=/tmp/info-ad-map.json\-- output= http://localhost:9200/abcd# Import log 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: you need to use-- net=host to mount the network to the container when using localhost:9200
