Purpose

Install Zimbra Collaboration Server and DNS Server with a Script, in a Single-Server, using Docker.

Resolution

Before you start

This guide is not officially supported by Zimbra, as docker is not in the Operating System, or Virtualization Supported platforms in the System Requirements.

This guide is intended for testing platforms, development, etc.

What is Docker

From the official docker website - Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. Consisting of a Docker Engine, a portable, lightweight runtime and packaging tool, and Docker Hub, a cloud service for sharing applications and automating workflows, Docker enables apps to be quickly assembled from components and eliminates the friction between development, QA, and production environments. As a result, IT can ship faster and run the same app, unchanged, on laptops, data center VMs, and any cloud.

Advantages of using Docker and the ZimbraEasyInstall Script

  • Time saving
  • Fully automated
  • Easy to use
  • Great for a quick Zimbra Preview

Installing Docker

First you need to install Docker on the server that you would like to use as a host for the docker containers. For example, here the instructions to install docker in Ubuntu 14.04:

wget -qO- https://get.docker.com/ | sh

If you want to install Docker in a different platform, please follow the next guide - https://docs.docker.com/installation/#installation

One of the advantages of using docker is that the host OS does not matter, the containers will work on any platform.

Creating the Zimbra Image

The content of the Dockerfile and the start.sh is based on the next Script - ZimbraEasyInstall. The Dockerfile creates a Ubuntu Server 14.04 image and install on it wget, then when the container is launched, automatically starts with the start.sh script:

Using git

Download from github, you will need git installed on your OS

git clone https://github.com/Zimbra-Community/zimbra-docker.git
Using wget

For those who want to use wget, follow the next instructions to download the Zimbra-docker package. You might need wget and unzip installed on your OS

wget https://github.com/Zimbra-Community/zimbra-docker/archive/master.zip
unzip master.zip

Build the image using the Dockerfile

The Makefile in the docker/ directory provides you with a convenient way to build your docker image. You might need make on your OS. Just run

cd zimbra-docker/docker
sudo make

The default image name is zimbra_docker. You can specify a different image name by setting the Image variable:

cd zimbra-docker/docker
sudo IMAGE=your_image_name make

You will see the next Steps:

docker build --rm -t zimbra_docker .

Deploy the Docker container

Now to deploy the container based on the previous image. As well as publish the Zimbra Collaboration ports, the hostname and the proper DNS, as you want to use bind as a local DNS nameserver within the container, also we will send the password that we want to our Zimbra Server like admin password, mailbox, LDAP, etc.: Syntax:

docker run -p PORTS -h HOSTNAME.DOMAIN --dns DNSSERVER -i -t -e PASSWORD=YOURPASSWORD NAMEOFDOCKERIMAGE

Example:

docker run -p 25:25 -p 80:80 -p 456:456 -p 587:587 -p 110:110 -p 143:143 -p 993:993 -p 995:995 -p 443:443 -p 8080:8080 -p 8443:8443 -p 7071:7071 -p 9071:9071 -h zimbra86-docker.zimbra.io --dns 127.0.0.1 --dns 8.8.8.8 -i -t -e PASSWORD=Zimbra2015 zimbra_docker

This will create the container in few seconds, and run automatically the start.sh:

  • Install a DNS Server based in bind9 and the dnsutils package
  • Configure all the DNS Server to resolve automatically internal the MX and the hostname that we define while launch the container.
  • Install the OS dependencies for Zimbra Collaboration 8.6
  • Create 2 files to automate the Zimbra Collaboration installation, the keystrokes and the config.defaults.
  • Launch the installation of Zimbra based only in the .install.sh -s
  • Inject the config.defaults file with all the parameters that is autoconfigured with the Hostname, domain, IP, and password that you define before.

The script takes a few minutes, dependent on the your Internet Speed, and resources.

Access to the Web Client and Admin Console

The Script will take care of everything and after a few minutes you can go to the IP address of your server and use the following URLs:
