Ian Wienand 1ac445b1d9 nodepool-base: prefer ZK IPv6 addresses
The current loop here uses the ansible_host value of the ZK servers,
which we have set to the IPv4 address in the inventory.

nb03 is constantly dropping out of ZK; for the record the logs record:

 2021-04-21 05:56:15,151 WARNING kazoo.client: Connection dropped: socket connection error: Connection reset by peer
 2021-04-21 05:56:15,151 WARNING kazoo.client: Transition to CONNECTING
 2021-04-21 05:56:15,151 INFO kazoo.client: Zookeeper connection lost
 2021-04-21 05:56:15,152 INFO kazoo.client: Connecting to 23.253.90.246(23.253.90.246):2281, use_ssl: True
 2021-04-21 05:56:15,176 INFO kazoo.client: Zookeeper connection established, state: CONNECTED

and this happens every few minutes.  This cloud does IPv4 behind a NAT
and it seems very likely this is related.

So the primary motivation here is to see if using IPv6 clears this up,
giving us some datapoints.  However I think that our other nodepool
hosts should all be fine to use ZK over IPv6.  However, I think in the
gate we may have cases where hosts don't have IPv6 addresses, so this
looks for the v6 address and if not found, falls back to the current
ansible_host behaviour.

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.

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 or you could check historical runs on the pipeline results (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 channel is the main place for interactive discussion. Feel free to ask any questions and someone will try to help ASAP. The OpenDev meeting is a co-ordinated time to synchronize on infrastructure issues. Issues should be added to the agenda 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 mailing list where you are welcome to send queries or questions.
