Install ownCloud on Ubuntu 14.04 Using Docker

This article was written based on the exact step-by-step process used to create an ownCloud Server using Ubuntu 14.04 with Docker from a new 512MB Cloud Instance from Codero Hosting. Each step is documented starting from the initial log into the server.

Requirements:
SSH root access to the server.
Use of Nano text editor.

Update Ubuntu

apt-get -y update

As of 04-15-2016, the installed version of Docker is unsupported and must be updated.

apt-get -y upgrade

Edit the firewall to allow forwarding traffic required by oneCloud

nano /etc/default/ufw

Scroll down and change DEFAULT_FORWARD_POLICY to “ACCEPT”

#DEFAULT_FORWARD_POLICY="DROP"
DEFAULT_FORWARD_POLICY="ACCEPT"

Save and exit the file.
*the firewall should not be running yet, so we’ll leave it off for now.
