Ansible deployment of the Kolla containers

Will Szumski 6f536a4f71 Put etcd behind HTTP loadbalancer etcd-compatible tooz drivers do not support multiple endpoints via backend_url. We can put a loadbalancer in front of etcd and configure backend_url to use the VIP instead. The issue with hard coding the first host is that we break coordination if we take this host offline. In the case of cinder, we would not be able to perform any volume related operations.

Kolla Ansible

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:

Collectd, Telegraf, InfluxDB, Prometheus, and Grafana for performance monitoring.
OpenSearch and OpenSearch Dashboards 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.
Open vSwitch for use with Neutron.
RabbitMQ as a messaging backend for communication between services.
Redis an in-memory data structure store.

Directories
