XOS Docker Images

Introduction

XOS is comprised of 3 core services:

• A database backend (postgres)
• A webserver front end (django)
• A synchronizer daemon that interacts with the openstack backend.

We have created separate dockerfiles for each of these services, making it easier to build the services independently and also deploy and run them in isolated environments.

Database Container

To build and run the database container:

$ cd postgres; make build && make run

XOS Container

To build and run the xos webserver container:

$ cd xos; make build && make run

You should now be able to access the login page by visiting http://localhost:8000 and log in using the default padmin@vicci.org account with password letmein. It may be helpful to bootstrap xos with some sample data; deployment, controllers, sites, slices, etc. You can get started by loading tosca configuration for the opencloud demo dataset:

$ cd xos; make runtosca

Or you can create you own tosca configuraton file and customize the dataset however you want. You can all load your own tosca configuration by setting the TOSCA_CONFIG_PATH environment variable before executing the make command:

$ cd xos; TOSCA_CONFIG_PATH=/path/to/tosca/config.yaml make runtosca

Synchronizer Container

The Synchronizer shares many of the same dependencies as the xos container. The synchronizer container takes advantage of this by building itself on top of the xos image. This means you must build the xos image before building the synchronizer image. The XOS and synchronizer containers can run on separate hosts, but you must build the xos image on the host that you plan to run the synchronizer container. Assuming you have already built the xos container, executing the following will build and run the synchronizer container:

$ cd synchronizer; make build && make run

Solution Compose File

Docker Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a Compose file to configure your application’s services. Then, using a single command, you create, start, scale, and manage all the services from your configuration.

Included is a compose file in YAML format with content defined by the Docker Compose Format. With the compose file a complete XOS solution based on docker containers can be instantiated using a single command. To start the instance you can use the command:

$ docker-compose -f xos-compose.yml up -d
