Running Owncloud on Docker

dockerManaging multiple appliances on the same server allways had its issues: Dependencies and updates are a risk you have to get over with in order to keep an up to date and secure service.

Docker is a technology that has been giving a lot to talk lately.

Imagine a world where you don’t have to worry about dependencies or configurations gone wrong: Docker is here for this purpose.

It’s not virtualization like we are used to with Virtualbox, VMWare or such. This is a technology involving completely isolated containers with different purposes. Completely abstracted from the underlying OS, so, in case an appliance becomes unstable, the other ones running ont he same server stay unharmed.

With this in mind, you can have a docker daemon running on a Ubuntu Server or CentOS, for example and be running multiple sub-systems (called containers) at the same time.

They offer a public repository of appliances on their web page . This is a public repository contributed by users from all around the world and organizations: Anyone can pack a new appliance and submit it to docker hub so anyone else can pull it on their machine and run it in minutes.

This is how you can get the simplest owncloud installation you can imagine.

First, you should have docker daemon running on your machine.

On Arch LINUX, follow their wiki:

For Ubuntu, they have a dedicated section on how to configure it:

Once it’s working, you only have to pull the image:

docker pull owncloud

Optionally, create a persistent storage volume, so the data stays out of the docker image, and on your real OS’s filesystem:

mkdir /owncloudData

And finally, run the image on a container:

docker run –restart=always -d -p 80:80 -v /owncloudData:/var/www/html owncloud

Then, just point your browser to the machine where the docker daemon is running and you’ll find the initial screen where you can create your user and, optionally, select the database backend you want to use.

By default, it uses sqlite, which is a good choice for portability and if you want to keep a simple installation to use with few users, but you can modify this.

It couldn’t be simpler.
