There are a number of related projects in the project GitHub repositories, I’ll call out a few key ones here:

Choria Plugins

A number of Ruby based plugins are maintained in the Choria Plugins organisation, these provide features such as Package, Service and Puppet management. Many of them are installed by default when you install Choria but it’s worth a check what else is there. They are all distributed as Forge Modules.

Stream Replicator

Choria uses technology from in its Network Broker, Choria Streams is a managed instance of NATS JetStream. The Data Adapters supports bridging Registration and Choria Replies onto a Choria Streams service.

You might have multiple data centers and want to transport these registration data to a central location in a way that is resilient to network outage and would support building multiple caches of data in multiple locations with different freshness cadences. You can also subscribe entirely different kinds of processor for the data and each processor can consume the data at its own pace.

This is a key component to be able to build scalable asynchronous REST systems, schedulers and more.

The Choria Stream Replicator is the tool to achieve this and other tools mentioned below are developed to be compatible with data flows managed using it.

Choria Embeddable Backplane

In a modern containerised world the use for a general purpose orchestration server like the main Choria Server is a bit limited, if you write your Microservices in Go though you can use the Choria Embeddable Backplane to gain Circuit Breakers, Health Checks and Emergency Shutdown features that live on the Choria Broker Network where you can manage these Microservices using the CLI, Ruby API, Go API or Choria Playbooks.

Tools like the Stream Replicator and Prometheus Streams will feature this Backplane to manage their internals. The Choria Server Provisioner already incorporates it.

A video demonstrating this capability can be seen below:

Choria Server Provisioner

In large dynamic environments where you do not have configuration management systems like Puppet or wish to do custom CA integration we provide a provisioning system that gives you full control over the life cycle of the Choria Daemon, unconfigured daemons enter a provisioning state where a software component can reach out to them and configure them.

This is an advanced feature and requires custom builds to be made (but we provide the tools for this).

See the documentation in provisioner.

A video demonstrating this capability can be seen below:

Helm Charts

As part of the Scout project we are working on a fully Kubernetes hosted solution that’s independent of Puppet. It auto enrolls nodes, auto configures them and manage their life cycle completely without needing any external components.
