XOS is comprised of 3 core services:
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.
To build the database container:
$ cd postgresql; make build
To build the XOS webserver container:
$ cd xos; make build
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. Assuming you have already built the XOS container, executing the following will build the Synchronizer container:
$ cd synchronizer; make build
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 up -d
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.
There are many possible configurations of XOS. The best way to get started is to find the configuration that best matches your needs and modify it as necessary. The available "canned" configurations can be found i ../xos/configurations/.
If you have your own OpenStack cluster, and you would like to configure XOS to control it, then take the following steps. Copy the admin-openrc.sh credentials file for your cluster to this directory. Make sure that OpenStack commands work from the local machine using the credentials, e.g., source ./admin-openrc.sh; nova list. Then run:
$ make
XOS will be launched (the Makefile will run the docker-compose up -d command for you) and configured with the nodes and images available in your OpenStack cloud. You can then log in to XOS as described above and start creating slices and instances.
