This is a small Python3 utility to copy indexes, mappings, and settings from one ElasticSearch cluster to another.

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Python 3, Requests, optionally virtualenv and pip.

Clone the repository.

git clone https://github.com/crisvp/copy-cluster.git

Set up a virtualenv and install the requirements:

pipenv install

Verify she chooches:

./copy-cluster.py -h

This will copy indexes, aliases, and settings from one cluster to another. Data is not copied. For that, use a tool like logstash or elasticsearch-reindex.

The destination cluster should be completely empty so that indexes and aliases can be created. The tool is fairly basic. Any errors are passed on as exceptions, the tool will crash, and you will have to manually bring the destination cluster back into an empty state. Typically this just means deleting the indexes.

This will copy all indexes, settings, and aliases from the cluster at localhost:9200 to the cluster at localhost:9201:

./copy-cluster.py http://localhost:9200 http://localhost:9201
