Docker image of a running solr instance for dovecot

This repo contains a running instance of solr optimized for dovecot.

Build architecture

The images are automatically build at the docker hub: https://hub.docker.com/r/lmmdock/dovecot-solr

Tested with

• dovecot 2.2.9 on Ubuntu 14.04 LTS
• dovecot 2.2.22 on Ubuntu 16.04 LTS

First steps

Before you start please note the two main problems with this docker image:

1. This image contains a solr instance which is not compatible to all versions of dovecot by default; up to date versions should work out of the box
2. This image does not support any authentication or encryption

Installation of solr

Simply execute

docker run -d -p 127.0.0.1:8983:8983 -t lmmdock/dovecot-solr:latest

on your server running dovecot

Afterwards you can access the solr admin panel at http://127.0.0.1:8983/solr

Hooking up dovecot

Afterwards you have to configure the solr usage in dovecot like described at http://wiki2.dovecot.org/Plugins/FTS/Solr

Please note that the url schema has changed a bit; you probably should use this url: http://localhost:8983/solr/dovecot/

Dovecot 2.2.9

With dovecot version 2.2.9 there is a problem with dovecot's header setting here: https://github.com/dovecot/core/blob/master/src/plugins/fts-solr/solr-connection.c#L490

I solved the problem by removing the line completly.

Working out of the box.
