Tungsten Fabric operator

Tungsten Fabric operator

The Tungsten Fabric operator (TFO) is based on the operator SDK project. The operator SDK is a framework that uses the controller-runtime library to make writing operators easier by providing:

  • High-level APIs and abstractions to write the operational logic more intuitively.

  • Tools for scaffolding and code generation to bootstrap a new project fast.

  • Extensions to cover common operator use cases.

The TFO deploys the following sub-operators. Each sub-operator handles a separate part of a TF deployment:

TFO sub-operators

Network

Description

TFControl

Deploys the Tungsten Fabric control services, such as:

  • Control

  • DNS

  • Control NodeManager

TFConfig

Deploys the Tungsten Fabric configuration services, such as:

  • API

  • Service monitor

  • Schema transformer

  • Device manager

  • Configuration NodeManager

  • Database NodeManager

TFAnalytics

  • API

  • Collector

  • Alarm

  • Alarm-gen

  • SNMP

  • Topology

  • Alarm NodeManager

TFVrouter

Deploys a vRouter on each compute node with the following services:

  • vRouter agent

  • NodeManager

TFWebUI

Deploys the following web UI services:

  • Web server

  • Job server

TFTool

Deploys the following tools to verify the TF deployment status:

  • TF-status

  • TF-status aggregator

TFTest

An operator to run Tempest tests.

Besides the sub-operators that deploy TF services, TFO uses operators to deploy and maintain third-party services, such as different types of storage, cache, message system, and so on. The following table describes all third-party operators:

TFO third-party sub-operators

Network

Description

casandra-operator

An upstream operator that automates the Cassandra HA storage operations for the configuration and analytics data.

zookeeper-operator

An upstream operator for deployment and automation of a ZooKeeper cluster.

kafka-operator

An operator for the Kafka cluster used by analytics services.

redis-operator

An upstream operator that automates the Redis cluster deployment and keeps it healthy.

rabbitmq-operator
