Ansible deployment of the Kolla containers

Go to file

Mark Goddard de00bf491d Simplify handler conditionals Currently, we have a lot of logic for checking if a handler should run, depending on whether config files have changed and whether the container configuration has changed. As rm_work pointed out during the recent haproxy refactor, these conditionals are typically unnecessary - we can rely on Ansible's handler notification system to only trigger handlers when they need to run. This removes a lot of error prone code. This patch removes conditional handler logic for all services. It is important to ensure that we no longer trigger handlers when unnecessary, because without these checks in place it will trigger a restart of the containers.

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.
Zookeeper an open-source server which enables highly reliable distributed coordination.

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.
