kibana-proxy

Hosts Kibana 3 as a nodejs express application.

Features:

• Proxy access to Elasticsearch: all elasticsearch queries are sent through the express application.
• Optional Google OAuth2 login with (passport)[http://passport.org].
• Support for Elasticsearch protected by basic-authentication: only the express app will know about the username and password.

Front-ends specifically tested:

• Kibana 3
• Head
• Bigdesk

Note regarding Kibana 4: it won't be supported here.

Please use Elastic's Shield or contribute to https://github.com/hmalphettes/kibana-auth-plugin or wait for elastic/kibana#3904

Longer story: Kibana 4 requires its own web-tier; it processes the requests issued by the browser and then sends them to Elasticsearch.

Reference: elastic/kibana#1628 (comment)

For Kibana 4 it seems an authentication plugin is what is needed to replace this proxy.

In fact Kibana 4 is a NodeJS app since RC1. We should be able to plug our middleware for authentication in a sniffy!

• APP_ID, APP_SECRET: Google OAuth2 config. Optional.
• AUTHORIZED_EMAILS: define what authenticated email is granted access; a comma separated listed of patterns; defaults to *. example: *@stoic.com,justme@gmail.com each pattern must be one-of:
  • *: anything,
  • *@domain: any email in the domain
