Zimbra Docker Container

Description

This is an attempt to deploy Zimbra open source edition as a Docker container. It tries to package the Zimbra server as a Docker image with all needed dependencies and really do be deployed.

Current State

The current state is that the Zimbra server docker image is created and can be deployed manually as a docker container. The step to deploy are currently:

  1. Setup A and MX entries for the Zimbra domain.

For testing purposes, a Bind server with Webmin interface can be started. The Zimbra domain needs to be configured to have an A and a MX record.

  • Start bind container with Webmin interface.
make bind-start
  • Example bind zone for Zimbra. The Zimbra domain will be zimbra.local with a mail domain mx1.local. The IP addresses must be changed.
$ttl 38400
local.  IN      SOA     ns1.local. admin.local. (
                        1480066280
                        30M
                        3600
                        30M
                        38400 )
local.  IN      NS      ns1.local.
local.  IN      A       172.17.0.4
ns1.local.      IN      A       172.17.0.3
zimbra.local.   IN      CNAME   local.
local.  IN      MX      10 mx1.local.
mx1.local.      IN      A       172.17.0.4
  1. Install Zimbra in the container on the host.
make zimbra-data zimbra-setup
  1. Start Zimbra on the host.
make zimbra

Issues

  • If trying on a test machine with the bind container, the IP addresses can be mixed up depending on how many containers are already running and the start order of the containers.

  • Server status is red for all services, but the services are running. Below is the list of running services inside the Docker container.

  • Need to mount /opt/zimbra, /var and /etc because the Zimbra setup modifies files in those directories and those modifications must be preserved. Below is a list of the modified files.
