Ansible deployment of the Kolla containers

Mark Goddard 365bb5177d Create cells before starting nova services Nova services may reasonably expect cell databases to exist when they start. The current cell setup tasks in kolla run after the nova containers have started, meaning that cells may or may not exist in the database when they start, depending on timing. In particular, we are seeing issues in kolla CI currently with jobs timing out waiting for nova compute services to start. The following error is seen in the nova logs of these jobs, which may or may not be relevant: No cells are configured, unable to continue This change creates the cell0 and cell1 databases prior to starting nova services. In order to do this, we must create new containers in which to run the nova-manage commands, because the nova-api container may not yet exist. This required adding support to the kolla_docker module for specifying a command for the container to run that overrides the image's command. We also add the standard output and error to the module's result when a non-detached container is run. A secondary benefit of this is that the output of bootstrap containers is now displayed in the Ansible output if the bootstrapping command fails, which will help with debugging.

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

Kolla-Ansible deploys containers for the following 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.
Redis an in-memory data structure store.

Directories

ansible - Contains Ansible playbooks to deploy OpenStack services and infrastructure components in Docker containers.
contrib - Contains demos scenarios for Heat, Magnum and Tacker and a development environment for Vagrant
doc - Contains documentation.
etc - Contains a reference etc directory structure which requires configuration of a small number of configuration variables to achieve a working All-in-One (AIO) deployment.
specs - Contains the Kolla-Ansible communities key arguments about architectural shifts in the code base.
tests - Contains functional testing tools.
tools - Contains tools for interacting with Kolla-Ansible.
