OpenDev System Configuration
============================
This is the machinery that drives the configuration, testing,
continuous integration and deployment of services provided by the
OpenDev project.
Services are driven by Ansible playbooks and associated roles stored
here. If you are interested in the configuration of a particular
service, starting at ``playbooks/service-<name>.yaml`` will show you
how it is configured.
Most services are deployed via containers; many of them are built or
customised in this repository; see ``docker/``.
A small number of legacy services are still configured with Puppet.
Although the act of running puppet on these hosts is managed by
Ansible, the actual core of their orchestration lives in ``manifests``
and ``modules``.
Testing
-------
OpenDev infrastructure runs a complete testing and
continuous-integration environment, powered by `Zuul
<https://zuul-ci.org/>`__.
Any changes to playbooks, roles or containers will trigger jobs to
thoroughly test those changes.
Tests run the orchestration for the modified services on test nodes
assigned to the job. After the testing deployment is configured
(validating the basic environment at least starts running), specific
tests are configured in the ``testinfra`` directory to validate
functionality.
Continuous Deployment
---------------------
Once changes are reviewed and committed, they will be applied
automatically to the production hosts. This is done by Zuul jobs
running in the ``deploy`` pipeline. At any one time, you may see
these jobs running live on the `status page
<https://zuul.opendev.org/t/openstack/status>`__ or you could check
historical runs on the `pipeline results
<https://zuul.opendev.org/t/openstack/builds?pipeline=deploy>`__ (note
there is also an ``opendev-prod-hourly`` pipeline, which ensures
things like upstream package updates or certificate renewals are
incorporated in a timely fashion).
Contributing
============
Contributions are welcome!
You do not need any special permissions to make contributions, even
those that will affect production services. Your changes will be
automatically tested, reviewed by humans and, once accepted, deployed
automatically.
Bug fixes or modifications to existing code are great places to start,
and you will see the results of your changes in CI testing.
You can develop all the playbooks, roles, containers and testing
required for a new service just by uploading a change. Using a
similar service as a template is generally a good place to start. If
deploying to production will require new compute resources (servers,
volumes, etc.) these will have to be deployed by an OpenDev
administrator before your code is committed. Thus if you know you
will need new resources, it is best to coordinate this before review.
The `#opendev` IRC on OFTC
channel is the main place for interactive discussion. Feel free to
ask any questions and someone will try to help ASAP. The `OpenDev
meeting <https://meetings.opendev.org/#OpenDev_Meeting>`__ is a
co-ordinated time to synchronize on infrastructure issues. Issues
should be added to the `agenda
<https://wiki.openstack.org/wiki/Meetings/InfraTeamMeeting>`__ for
discussion; even if you can not attend, you can raise your issue and
check back on the logs later. There is also the `service-discuss
<http://lists.opendev.org/cgi-bin/mailman/listinfo/service-discuss>`__
mailing list where you are welcome to send queries or questions.
