This is a Dockerfile and some supporting bits for running Couchbase Server in a Docker container.

NOTE: This project is currently being updated to use the new Docker official Mac OS X support.

There is a Vagrantfile in the vagrant directory that is configured to prepare an Ubuntu 12.04 VirtualBox host for Docker and the requisite bits needed by Couchbase Server, such as increasing open file limits and locked memory as detailed below. If you use the supplied Vagrantfile, the steps in the following section will be done for you when you vagrant up, and you will not need to do them by hand.

Note about open file limits and locked memory: You'll need to increase the number of open files and locked memory available to Couchbase Server containers from the Docker host.

To do so, first ssh into the Docker host machine and ensure that the /etc/init directory is present:

sudo mkdir /etc/init

Next, edit /etc/init/docker.conf:

sudo $EDITOR /etc/init/docker.conf

Then, append the following lines to the end of the file:

limit memlock unlimited unlimited
limit nofile 262144 262144

You'll need to restart the Docker daemon or host machine after making the above changes. These changes will affect the Docker daemon and all of its children, including containers.

To restart the entire Docker host:

boot2docker restart

Prior to building and running the container, you'll need to prepare a directory on the Docker host for mapping the Couchbase Server data directory if you wish to preserve your data through restarts of the image.

First, ssh into the Docker host, the execute the following commands:

sudo mkdir /home/couchbase-server
sudo chown 999:999 /home/couchbase-server

Now, you can build and run a Couchbase Server Docker container; be sure to replace <yourname> in the example shown below with your own unique identifier.

Clone this project into the /home/docker directory on the Docker host:

git clone https://github.com/brianshumate/docker-couchbase-server.git

Then, execute the following commands to build a container:

cd docker-couchbase-server
sudo docker build -t <yourname>/couchbase-server .

A command like the following is used to run the container:

sudo docker run -i -t  -p 11210:11210 -p 8091:8091 -p 8092:8092 \
<yourname>/couchbase-server

or, if you prefer to have the container run in the background:

sudo docker run -i -t -d -p 11210:11210 -p 8091:8091 -p 8092:8092 \
<yourname>/couchbase-server

To use this project on Mac OS X with official Docker support and the boot2docker tool, follow these instructions:

Install the boot2docker script with Homebrew:

brew install boot2docker

Learn more about Docker Mac OS X support in the Mac OS X installation documentation

Once you've installed boot2docker you can install the latest Docker Mac OS X client with Homebrew:

brew install docker

Now initialize and boot the Docker daemon and VM:

boot2docker init
boot2docker up

Using the Docker client will now work as expected agains the VirtualBox based VM host:

docker version

You can also easily ssh into the VM:

boot2docker ssh

• User name : root
• Password : tcuser

Once you've established the Docker host, you can follow the directions under Prepare Docker Host and Build & Run a Container to get the project up and running.
