Zercurity is supported on RHEL/CentOS/Fedora.

.. note::

   This installation assumes you are installing Zercurity as a system user
   called **admin** under the working directory ``/home/admin``. You can
   install Zercurity to any system directory. Just make sure to update
   the volumes section within the ``docker-compose.yml`` file.

Installing Docker
=================

As the user **root** run the following commands to install Docker.

.. code-block:: bash

   yum install -y yum-utils device-mapper-persistent-data lvm2
   yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
   yum install -y docker-ce docker-ce-cli

   # Add the docker user to your user group to avoid permission errors
   # we're using the user admin in this example.
   usermod -aG docker admin

   systemctl start docker

Installing Docker Compose
=========================

In order to deploy Zercurity and keep it up-to-date Docker Compose is required.

.. code-block:: bash

   yum install -y python3-pip
   pip3 install --upgrade docker-compose

Starting Zercurity
==================

To setup Zercurity copy across the installation files. Provided to you by
your account manager. The ``./setup.sh`` script will guide you through the
process.

.. code-block:: bash

   # You'll be required to enter the domain name you want to use
   # which will update your **production.dev** file which stores all
   # configuration settings. The setup will also download the latest
   # version of Zercurity for Docker.
   ./setup.sh

   systemctl start zercurity

Updating Zercurity
==================

.. code-block:: bash

   # There is no need to shutdown Zercurity. The new image containers will
   # be fetched and used the next time the service is restarted.
   ./update.sh

   systemctl restart zercurity
