Zimbra Docker Container
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.
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:
- 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.
- Example bind zone for Zimbra. The Zimbra domain will be
zimbra.localwith a mail domain
mx1.local. The IP addresses must be changed.
$ttl 38400 local. IN SOA ns1.local. admin.local. ( 1480066280 30M 3600 30M 38400 ) local. IN NS ns1.local. local. IN A 172.17.0.4 ns1.local. IN A 172.17.0.3 zimbra.local. IN CNAME local. local. IN MX 10 mx1.local. mx1.local. IN A 172.17.0.4
- Install Zimbra in the container on the host.
make zimbra-data zimbra-setup
- Start Zimbra on the host.
If trying on a test machine with the bind container, the IP addresses can be mixed up depending on how many containers are already running and the start order of the containers.
Server status is red for all services, but the services are running. Below is the list of running services inside the Docker container.
zimbra@zimbra:~$ zmcontrol status Host zimbra.local amavis Running antispam Running antivirus Running dnscache Running ldap Running logger Running mailbox Running memcached Running mta Running opendkim Running proxy Running service webapp Running snmp Running spell Running stats Running zimbra webapp Running zimbraAdmin webapp Running zimlet webapp Running zmconfigd Running
- Need to mount
/etcbecause the Zimbra setup modifies files in those directories and those modifications must be preserved. Below is a list of the modified files.

The idea for the image was taken from the zimbra-docker Git repository.
