Curator can be installed in a variety of ways, depending on what meets your needs. It is important to note that Curator only requires access to a client node in the Elasticsearch cluster to work. It need not be installed on one of the nodes in the cluster if you do not want it that way.

If you plan on using SSL/TLS to connect to Elasticsearch, you may encounter issues with older versions of Python and outdated libraries. The binary packages have been compiled with up-to-date versions for your convenience. See the security page for more information.
