Fix nova deploy with Ansible<2.8

Mark Goddard authored 5 years ago

Due to a bug in ansible, kolla-ansible deploy currently fails in nova
with the following error when used with ansible earlier than 2.8:

TASK [nova : Waiting for nova-compute services to register themselves]
*********
task path:
/home/zuul/src/opendev.org/openstack/kolla-ansible/ansible/roles/nova/tasks/discover_computes.yml:30
fatal: [primary]: FAILED! => {
    "failed": true,
    "msg": "The field 'vars' has an invalid value, which
        includes an undefined variable. The error was:
        'nova_compute_services' is undefined\n\nThe error
        appears to have been in
        '/home/zuul/src/opendev.org/openstack/kolla-ansible/ansible/roles/nova/tasks/discover_computes.yml':
        line 30, column 3, but may\nbe elsewhere in the file
        depending on the exact syntax problem.\n\nThe
        offending line appears to be:\n\n\n- name: Waiting
        for nova-compute services to register themselves\n ^
            here\n"
}

Example:
http://logs.openstack.org/00/669700/1/check/kolla-ansible-centos-source/81b65b9/primary/logs/ansible/deploy

This was caused by
https://review.opendev.org/#/q/I2915e2610e5c0b8d67412e7ec77f7575b8fe9921,
which hits upon an ansible bug described here:
https://github.com/markgoddard/ansible-experiments/tree/master/05-referencing-registered-var-do-until.

We can work around this by not using an intermediary variable.

Kolla-Ansible Overview

The Kolla-Ansible is a deliverable project separated from Kolla project.

Kolla-Ansible deploys OpenStack services and infrastructure components in Docker containers.

Kolla's mission statement is:

To provide production-ready containers and deployment tools for operating
OpenStack clouds.

Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.

Getting Started

Learn about Kolla-Ansible by reading the documentation online Kolla-Ansible.

Get started by reading the Developer Quickstart.

OpenStack services

Kolla-Ansible deploys containers for the following OpenStack projects:

Infrastructure components

Ceph implementation for Cinder, Glance and Nova.
Collectd, Telegraf, InfluxDB, Prometheus, and Grafana for performance monitoring.
Elasticsearch and Kibana to search, analyze, and visualize log messages.
Etcd a distributed reliable key-value store.
Fluentd as an open source data collector for unified logging layer.
Gnocchi A time-series storage database.
HAProxy and Keepalived for high availability of services and their endpoints.
MariaDB and Galera Cluster for highly available MySQL databases.
Memcached a distributed memory object caching system.
MongoDB as a database back end for Panko.
Open vSwitch and Linuxbridge backends for Neutron.
RabbitMQ as a messaging backend for communication between services.
